    Ecology. Can science rescue salmon? (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-08-19
    Description: At a press conference on 27 July, the National Marine Fisheries Service (NMFS) released a long-awaited plan to save the Columbia River's endangered salmon by restoring fish habitat, overhauling hatcheries, limiting harvest, and improving river flow. What the plan did not do, however, was call for immediate breaching of four dams on the Snake River, the Columbia's major tributary--an option that has been the subject of a nationwide environmental crusade. The NMFS will hold that option in abeyance while it sees whether the less drastic measures will do the trick. Responses from both sides were immediate and outraged.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mann, C C -- Plummer, M L -- New York, N.Y. -- Science. 2000 Aug 4;289(5480):716-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10950712" target="_blank"〉PubMed〈/a〉

    Impacts of climatic change and fishing on Pacific salmon abundance over the past 300 years (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-10-29
    Description: The effects of climate variability on Pacific salmon abundance are uncertain because historical records are short and are complicated by commercial harvesting and habitat alteration. We use lake sediment records of delta15N and biological indicators to reconstruct sockeye salmon abundance in the Bristol Bay and Kodiak Island regions of Alaska over the past 300 years. Marked shifts in populations occurred over decades during this period, and some pronounced changes appear to be related to climatic change. Variations in salmon returns due to climate or harvesting can have strong impacts on sockeye nursery lake productivity in systems where adult salmon carcasses are important nutrient sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finney, B P -- Gregory-Eaves, I -- Sweetman, J -- Douglas, M S -- Smol, J P -- New York, N.Y. -- Science. 2000 Oct 27;290(5492):795-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Marine Science, University of Alaska Fairbanks, Fairbanks, AK 99775, USA. finney@ims.uaf.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11052941" target="_blank"〉PubMed〈/a〉

    Description: Using a novel technique, described on page 795, paleoceanographers have been able to chart the abundance of sockeye salmon in the Bristol Bay and Kodiak Island regions of Alaska over the past 300 years--by far the most complete record yet. Through time, they found, sockeye populations have alternately soared and slipped, following natural climate variations--well before commercial fishers began throwing nets over the sides of boats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, K -- New York, N.Y. -- Science. 2000 Oct 27;290(5492):685-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11184190" target="_blank"〉PubMed〈/a〉

    Homogenization of fish faunas across the United States (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-08
    Description: Fish faunas across the continental United States have become more similar through time because of widespread introductions of a group of cosmopolitan species intended to enhance food and sport fisheries. On average, pairs of states have 15.4 more species in common now than before European settlement of North America. The 89 pairs of states that formerly had no species in common now share an average of 25.2 species. Introductions have played a larger role than extirpations in homogenizing fish faunas. Western and New England states have received the most introductions, which is a reflection of the small number of native fishes in these areas considered desirable gamefish by settlers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rahel, F J -- New York, N.Y. -- Science. 2000 May 5;288(5467):854-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA. frahel@uwyo.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10797007" target="_blank"〉PubMed〈/a〉

    Migratory movements, depth preferences, and thermal biology of Atlantic bluefin tuna (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-08-18
    Description: The deployment of electronic data storage tags that are surgically implanted or satellite-linked provides marine researchers with new ways to examine the movements, environmental preferences, and physiology of pelagic vertebrates. We report the results obtained from tagging of Atlantic bluefin tuna with implantable archival and pop-up satellite archival tags. The electronic tagging data provide insights into the seasonal movements and environmental preferences of this species. Bluefin tuna dive to depths of 〉1000 meters and maintain a warm body temperature. Western-tagged bluefin tuna make trans-Atlantic migrations and they frequent spawning grounds in the Gulf of Mexico and eastern Mediterranean. These data are critical for the future management and conservation of bluefin tuna in the Atlantic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Block, B A -- Dewar, H -- Blackwell, S B -- Williams, T D -- Prince, E D -- Farwell, C J -- Boustany, A -- Teo, S L -- Seitz, A -- Walli, A -- Fudge, D -- New York, N.Y. -- Science. 2001 Aug 17;293(5533):1310-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tuna Research and Conservation Center, Stanford University, Hopkins Marine Station, Oceanview Boulevard, Pacific Grove, CA 93950, USA. bblock@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11509729" target="_blank"〉PubMed〈/a〉

    A global map of human impact on marine ecosystems (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-02-16
    Description: The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers. However, large areas of relatively little human impact remain, particularly near the poles. The analytical process and resulting maps provide flexible tools for regional and global efforts to allocate conservation resources; to implement ecosystem-based management; and to inform marine spatial planning, education, and basic research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halpern, Benjamin S -- Walbridge, Shaun -- Selkoe, Kimberly A -- Kappel, Carrie V -- Micheli, Fiorenza -- D'Agrosa, Caterina -- Bruno, John F -- Casey, Kenneth S -- Ebert, Colin -- Fox, Helen E -- Fujita, Rod -- Heinemann, Dennis -- Lenihan, Hunter S -- Madin, Elizabeth M P -- Perry, Matthew T -- Selig, Elizabeth R -- Spalding, Mark -- Steneck, Robert -- Watson, Reg -- New York, N.Y. -- Science. 2008 Feb 15;319(5865):948-52. doi: 10.1126/science.1149345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, 735 State Street, Santa Barbara, CA 93101, USA. halpern@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18276889" target="_blank"〉PubMed〈/a〉

    Description: Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rooker, Jay R -- Secor, David H -- De Metrio, Gregorio -- Schloesser, Ryan -- Block, Barbara A -- Neilson, John D -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):742-4. doi: 10.1126/science.1161473.

    Publication Date: 2010-07-22
    Description: Since the collapse of the pelagic fisheries off southwest Africa in the late 1960s, jellyfish biomass has increased and the structure of the Benguelan fish community has shifted, making the bearded goby (Sufflogobius bibarbatus) the new predominant prey species. Despite increased predation pressure and a harsh environment, the gobies are thriving. Here we show that physiological adaptations and antipredator and foraging behaviors underpin the success of these fish. In particular, body-tissue isotope signatures reveal that gobies consume jellyfish and sulphidic diatomaceous mud, transferring "dead-end" resources back into the food chain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Utne-Palm, Anne C -- Salvanes, Anne G V -- Currie, Bronwen -- Kaartvedt, Stein -- Nilsson, Goran E -- Braithwaite, Victoria A -- Stecyk, Jonathan A W -- Hundt, Matthias -- van der Bank, Megan -- Flynn, Bradley -- Sandvik, Guro K -- Klevjer, Thor A -- Sweetman, Andrew K -- Bruchert, Volker -- Pittman, Karin -- Peard, Kathleen R -- Lunde, Ida G -- Strandabo, Ronnaug A U -- Gibbons, Mark J -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):333-6. doi: 10.1126/science.1190708.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Bergen, Bergen, Norway. anne.palm@bio.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20647468" target="_blank"〉PubMed〈/a〉

    Bushmeat hunting, wildlife declines, and fish supply in West Africa (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-11-13
    Description: The multibillion-dollar trade in bushmeat is among the most immediate threats to the persistence of tropical vertebrates, but our understanding of its underlying drivers and effects on human welfare is limited by a lack of empirical data. We used 30 years of data from Ghana to link mammal declines to the bushmeat trade and to spatial and temporal changes in the availability of fish. We show that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in biomass of 41 wildlife species. Local market data provide evidence of a direct link between fish supply and subsequent bushmeat demand in villages and show bushmeat's role as a dietary staple in the region. Our results emphasize the urgent need to develop cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions of tropical wildlife.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brashares, Justin S -- Arcese, Peter -- Sam, Moses K -- Coppolillo, Peter B -- Sinclair, A R E -- Balmford, Andrew -- New York, N.Y. -- Science. 2004 Nov 12;306(5699):1180-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Conservation Biology Group, Department of Zoology, University of Cambridge, Cambridge CB2 3EJ, UK. brashares@nature.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15539602" target="_blank"〉PubMed〈/a〉

    Climate impact on plankton ecosystems in the Northeast Atlantic (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-09-14
    Description: It is now widely accepted that global warming is occurring, yet its effects on the world's largest ecosystem, the marine pelagic realm, are largely unknown. We show that sea surface warming in the Northeast Atlantic is accompanied by increasing phytoplankton abundance in cooler regions and decreasing phytoplankton abundance in warmer regions. This impact propagates up the food web (bottom-up control) through copepod herbivores to zooplankton carnivores because of tight trophic coupling. Future warming is therefore likely to alter the spatial distribution of primary and secondary pelagic production, affecting ecosystem services and placing additional stress on already-depleted fish and mammal populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richardson, Anthony J -- Schoeman, David S -- New York, N.Y. -- Science. 2004 Sep 10;305(5690):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sir Alister Hardy Foundation for Ocean Science, The Laboratory, Citadel Hill, Plymouth, PL1 2PB, UK. anr@sahfos.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15361622" target="_blank"〉PubMed〈/a〉

    Global patterns of predator diversity in the open oceans (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-07-30
    Description: The open oceans comprise most of the biosphere, yet patterns and trends of species diversity there are enigmatic. Here, we derive worldwide patterns of tuna and billfish diversity over the past 50 years, revealing distinct subtropical "hotspots" that appeared to hold generally for other predators and zooplankton. Diversity was positively correlated with thermal fronts and dissolved oxygen and a nonlinear function of temperature (approximately 25 degrees C optimum). Diversity declined between 10 and 50% in all oceans, a trend that coincided with increased fishing pressure, superimposed on strong El Nino-Southern Oscillation-driven variability across the Pacific. We conclude that predator diversity shows a predictable yet eroding pattern signaling ecosystem-wide changes linked to climate and fishing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worm, Boris -- Sandow, Marcel -- Oschlies, Andreas -- Lotze, Heike K -- Myers, Ransom A -- New York, N.Y. -- Science. 2005 Aug 26;309(5739):1365-9.

    Trophic cascades in a formerly cod-dominated ecosystem (2005)

    Details
    Publication Date: 2005-06-11
    Description: Removal of top predators from ecosystems can result in cascading effects through the trophic levels below, completely restructuring the food web. Cascades have been observed in small-scale or simple food webs, but not in large, complex, open-ocean ecosystems. Using data spanning many decades from a once cod-dominated northwest Atlantic ecosystem, we demonstrate a trophic cascade in a large marine ecosystem. Several cod stocks in other geographic areas have also collapsed without recovery, suggesting the existence of trophic cascades in these systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frank, Kenneth T -- Petrie, Brian -- Choi, Jae S -- Leggett, William C -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1621-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Oceans, Bedford Institute of Oceanography, Ocean Sciences Division, Post Office Box 1006, Dartmouth, Nova Scotia, B2Y 4A2, Canada. frankk@mar.dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15947186" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-05-14
    Description: We show that the distributions of both exploited and nonexploited North Sea fishes have responded markedly to recent increases in sea temperature, with nearly two-thirds of species shifting in mean latitude or depth or both over 25 years. For species with northerly or southerly range margins in the North Sea, half have shown boundary shifts with warming, and all but one shifted northward. Species with shifting distributions have faster life cycles and smaller body sizes than nonshifting species. Further temperature rises are likely to have profound impacts on commercial fisheries through continued shifts in distribution and alterations in community interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perry, Allison L -- Low, Paula J -- Ellis, Jim R -- Reynolds, John D -- New York, N.Y. -- Science. 2005 Jun 24;308(5730):1912-5.

    A general model for designing networks of marine reserves (2002)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2002-12-10
    Description: There is debate concerning the most effective conservation of marine biodiversity, especially regarding the appropriate location, size, and connectivity of marine reserves. We describe a means of establishing marine reserve networks by using optimization algorithms and multiple levels of information on biodiversity, ecological processes (spawning, recruitment, and larval connectivity), and socioeconomic factors in the Gulf of California. A network covering 40% of rocky reef habitat can fulfill many conservation goals while reducing social conflict. This quantitative approach provides a powerful tool for decision-makers tasked with siting marine reserves.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sala, Enric -- Aburto-Oropeza, Octavio -- Paredes, Gustavo -- Parra, Ivan -- Barrera, Juan C -- Dayton, Paul K -- New York, N.Y. -- Science. 2002 Dec 6;298(5600):1991-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Marine Biodiversity and Conservation, Scripps Institution of Oceanography, La Jolla, CA 92093, USA. esala@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12471258" target="_blank"〉PubMed〈/a〉

    Fishing, trophic cascades, and the process of grazing on coral reefs (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: Since the mass mortality of the urchin Diadema antillarum in 1983, parrotfishes have become the dominant grazer on Caribbean reefs. The grazing capacity of these fishes could be impaired if marine reserves achieve their long-term goal of restoring large consumers, several of which prey on parrotfishes. Here we compare the negative impacts of enhanced predation with the positive impacts of reduced fishing mortality on parrotfishes inside reserves. Because large-bodied parrotfishes escape the risk of predation from a large piscivore (the Nassau grouper), the predation effect reduced grazing by only 4 to 8%. This impact was overwhelmed by the increase in density of large parrotfishes, resulting in a net doubling of grazing. Increased grazing caused a fourfold reduction in the cover of macroalgae, which, because they are the principal competitors of corals, highlights the potential importance of reserves for coral reef resilience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mumby, Peter J -- Dahlgren, Craig P -- Harborne, Alastair R -- Kappel, Carrie V -- Micheli, Fiorenza -- Brumbaugh, Daniel R -- Holmes, Katherine E -- Mendes, Judith M -- Broad, Kenneth -- Sanchirico, James N -- Buch, Kevin -- Box, Steve -- Stoffle, Richard W -- Gill, Andrew B -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):98-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Spatial Ecology Lab, School of BioSciences, University of Exeter, Prince of Wales Road, Exeter EX4 4PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400152" target="_blank"〉PubMed〈/a〉

    Ecological role of purple sea urchins (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-11
    Description: Sea urchins are major components of marine communities. Their grazing limits algal biomass, and they are preyed upon by many predators. Purple sea urchins (Strongylocentrotus purpuratus) are among the best studied species. They live in environments that alternate between two stable states: luxuriant, species-rich kelp forests and sea urchin-dominated "barrens." The transition from one state to the other can be initiated by several factors, including the abundance of algal food, predators, storm intensities, and incidence of disease. Purple sea urchins compete with other grazers, some of which are important fishery resources (such as abalones and red sea urchins), and they are harvested for scientific research. Revelations from their genome will lead to a better understanding of how they maintain their ecological importance, and may in turn enhance their economic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearse, John S -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):940-1.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Long Marine Laboratory, University of California, Santa Cruz, 100 Shaffer Road, Santa Cruz, CA 95060, USA. pearse@biology.ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095690" target="_blank"〉PubMed〈/a〉

    Publication Date: 2007-06-30
    Description: Like all species, humans have exercised their impulse to perpetuate and propagate themselves. In doing so, we have domesticated landscapes and ecosystems in ways that enhance our food supplies, reduce exposure to predators and natural dangers, and promote commerce. On average, the net benefits to humankind of domesticated nature have been positive. We have, of course, made mistakes, causing unforeseen changes in ecosystem attributes, while leaving few, if any, truly wild places on Earth. Going into the future, scientists can help humanity to domesticate nature more wisely by quantifying the tradeoffs among ecosystem services, such as how increasing the provision of one service may decrease ecosystem resilience and the provision of other services.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kareiva, Peter -- Watts, Sean -- McDonald, Robert -- Boucher, Tim -- New York, N.Y. -- Science. 2007 Jun 29;316(5833):1866-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nature Conservancy, 4245 North Fairfax Drive, Suite 100, Arlington, VA 22203, USA. pkareiva@tnc.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17600209" target="_blank"〉PubMed〈/a〉

    Cascading effects of the loss of apex predatory sharks from a coastal ocean (2007)

    Details
    Publication Date: 2007-03-31
    Description: Impacts of chronic overfishing are evident in population depletions worldwide, yet indirect ecosystem effects induced by predator removal from oceanic food webs remain unpredictable. As abundances of all 11 great sharks that consume other elasmobranchs (rays, skates, and small sharks) fell over the past 35 years, 12 of 14 of these prey species increased in coastal northwest Atlantic ecosystems. Effects of this community restructuring have cascaded downward from the cownose ray, whose enhanced predation on its bay scallop prey was sufficient to terminate a century-long scallop fishery. Analogous top-down effects may be a predictable consequence of eliminating entire functional groups of predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, Ransom A -- Baum, Julia K -- Shepherd, Travis D -- Powers, Sean P -- Peterson, Charles H -- New York, N.Y. -- Science. 2007 Mar 30;315(5820):1846-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Dalhousie University, 1355 Oxford Street, Halifax, NS B3H 4J1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17395829" target="_blank"〉PubMed〈/a〉

    Genetic effects of captive breeding cause a rapid, cumulative fitness decline in the wild (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-06
    Description: Captive breeding is used to supplement populations of many species that are declining in the wild. The suitability of and long-term species survival from such programs remain largely untested, however. We measured lifetime reproductive success of the first two generations of steelhead trout that were reared in captivity and bred in the wild after they were released. By reconstructing a three-generation pedigree with microsatellite markers, we show that genetic effects of domestication reduce subsequent reproductive capabilities by approximately 40% per captive-reared generation when fish are moved to natural environments. These results suggest that even a few generations of domestication may have negative effects on natural reproduction in the wild and that the repeated use of captive-reared parents to supplement wild populations should be carefully reconsidered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Araki, Hitoshi -- Cooper, Becky -- Blouin, Michael S -- New York, N.Y. -- Science. 2007 Oct 5;318(5847):100-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, 3029 Cordley Hall, Oregon State University Corvallis, OR 97331, USA. arakih@science.oregonstate.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17916734" target="_blank"〉PubMed〈/a〉

    Global seabird response to forage fish depletion--one-third for the birds (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-12-24
    Description: Determining the form of key predator-prey relationships is critical for understanding marine ecosystem dynamics. Using a comprehensive global database, we quantified the effect of fluctuations in food abundance on seabird breeding success. We identified a threshold in prey (fish and krill, termed "forage fish") abundance below which seabirds experience consistently reduced and more variable productivity. This response was common to all seven ecosystems and 14 bird species examined within the Atlantic, Pacific, and Southern Oceans. The threshold approximated one-third of the maximum prey biomass observed in long-term studies. This provides an indicator of the minimal forage fish biomass needed to sustain seabird productivity over the long term.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cury, Philippe M -- Boyd, Ian L -- Bonhommeau, Sylvain -- Anker-Nilssen, Tycho -- Crawford, Robert J M -- Furness, Robert W -- Mills, James A -- Murphy, Eugene J -- Osterblom, Henrik -- Paleczny, Michelle -- Piatt, John F -- Roux, Jean-Paul -- Shannon, Lynne -- Sydeman, William J -- New York, N.Y. -- Science. 2011 Dec 23;334(6063):1703-6. doi: 10.1126/science.1212928.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche pour le Developpement, UMR EME-212, Centre de Recherche Halieutique Mediterraneenne et Tropicale, Avenue Jean Monnet, Sete Cedex, France. philippe.cury@ird.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22194577" target="_blank"〉PubMed〈/a〉

    Description: Samples of the frozen hake (Merluccius capensis) were obtained once a week as corresponding to supply in Yenagoa Market Bayelsa State, Nigeria. From every supply of 10 cartons, 10 pieces of hake were examined for the presence of Anisakids nematodes. The incidence was concluded after sampling continuously every week for 8 weeks between September-November 2009. The highest parasite burden (13.2 ~c 2.28) was recorded in the second week and the lowest (8.5~c 2.9) in the 7th week, the highest mean weight of fish sample calculated was 134.80 ~c 19.16 gm in the 4th week and lowest in the 5th week with 118.30 ~c 3.56 g. The mean length was highest (29.10 ~c 1.90cm) in the second week and lowest (26.40 ~c 1.88 cm) in the 7th week. The percentage infection was 96.25% and very alarming since only 3 pieces were not infected as observed from all the samples examined.

    Description: The prevailence of protozoan and helminthic parasite species occurring on and in the internal organs of Oreochromis niloticus were studied. Twenty samples of a mixture of adult and juvenile individuals of Oreochromis niloticus were randomly obtained from fishermen landing at the jetties of Epe water side, Ikorodu (Odoguyan) river and a brackish water (makoko), between September and and October, 2009, during a period of low rainfall. Samples were eviscerated and the parasites were excised, identified and each specie of parasites was counted. Most of the parasites encountered were of the Protozoa, manogenea, Digenea, Cestoda and Nematoda groups. The infestation was predominantly by Nematoda species and followed by protozoan species. Protozoan parasites like Trichodina sp and Ichyobodo sp were found to be prevalent, in varying magnitude, in most of the fish samples without clear age discrimination. The study reveals that the prevailence of parasites infestation increases with increasing length, size and age of the fish host and different pars of the fish.

    Description: Mangrove swamps supply various goods and provide invaluable ecological services, especially as critical habitats for fish breeding. These functions are discussed in the context of rural livelihoods of coastal dwellers in the Niger Delta in particular, and the contribution to national economies in general. The decline in capture fisheries production in Nigeria is partly linked to massive mangrove loss in the Niger Delta. This provides basis for urgent evolution of effective mangrove conservation schemes in the Niger Delta and for focused research on the interaction between the delta mangroves and inland/coastal fish recruitment and production dynamics.

    Description: Standing on the abandoned jetty at Iwuochang / Upenekang fishing beach in 1999 [Ibeno LGA, Akwa Ibom State] and looking across the Qua Iboe River [en-route the Atlantic Ocean] were strips of luxuriant mangrove vegetation all around the estuary. Surprisingly, 10 years later still standing on the same jetty and looking across the same River also, all the vegetation round about the estuary are now replaced by nipa palms with pockets of mangrove plants. The fear of the paper is that, there may be crash in fish supply from the coastal waters of Nigeria in the near future. The time to act is now and FISON must be pro-active in this coastal re-construction and re-habilitation. Nigeria’s coastal water is a ‘food-basket’; much should be done to protect and jealously cherish it ? else, it may be the last standing mangrove forest ecosystem southeast of the Niger delta.

    Description: There are more occupational and health hazards in the Fishing Industry than in other occupational categories in the world. In Nigerian Industrial Fisheries, safety measures are regulated while little attention is given to safety standards in the artisanal fisheries. In West Africa, the coastal artisanal canoe fatality rates have been given in 1991-1994 to be 300 to 1,000 per 100,000 fishermen. Thus, the fatality rate in Nigerian artisanal fisheries, (coastal states) has been estimated to be 999 to 3,329 per 100,000 fishermen. The high rate is due to piracy, boundary disputes between fishing communities, unemployment, societal low value for human life and human labour. The paper discusses the various types of accidents associated with artisanal coastal fisheries and give recommendations. Fishermen have rights to safe working conditions in their working environment just as workers in offices and factories on land.

    Description: Twenty samples of canned seafood consisting of tuna, mackerel, sardines, prawn and shrimp were collected from retail operations in Victoria Island, Lagos, Nigeria. Mercury content in these canned seafood were determined after digestion by the Association of Official Analytical Chemists methods. The mercury contents for all the canned seafood products have concentrations well below the permissible EU levels for this toxic metal. Their contribution to the body burden can therefore be considered negligible and the canned seafood products seem to be safe for human consumption.

    Impact of oil exploration on fisherfolks' livelihood and safety of fisheries industry in Nigeria (2021)

    Description: There have been many outcries in the Nigerian media on the various environmental degradation of the vast water space in the Niger Delta area of Nigeria by oil explorers. About 70% of the Nigerian populace lives in the coastal areas where the occupation is predominantly fishing and farming. For most of the publications, the extents of impact on the fishing industry are not addressed in order for solutions to be given. Production from the fisheries sector has dropped astronomically thereby earning the country a deficit due to importation of frozen fish to the country. In this study, a survey of three states (Bayelsa, Rivers and Delta) in the Niger Delta area of Nigeria was done. The communities studied include Ogulagha, Okobelema and Okpoama. Personal interviews with fishermen and primary data on the sector’s contribution to fish production and GDP were also carried out. The study aimed at finding out the sources and nature of degradation and the impacts such have on the fishing industry and the socio-economics of the fishermen. The study revealed that there are no significant difference in the negative impacts of environmental degradation caused by the activities of the oil companies on the socio-economics of the fishermen ((F2,27=0.59, P〉0.05)) The difference is not significant and the hypothesis is therefore accepted. The major impact on fishing was depletion in catches and low income earnings by fishermen with a resultant poor quality of living and livelihood. Oil spills, foreign vessels incursions and bunkering, vandalization of pipelines were identified sources of depletion in fish catches from the wild. The personal interviews and Focus Group Discussion (FGDs) showed that most heads of communities rely on the remuneration they get from the companies and refused to mobilize the fishermen for joint action against the oil companies. Mitigation measures usually carried out by the oil companies do not actually replenish the destroyed mangroves where breeding of fishes take place. The communities need the Government to institute high level surveillance of the high seas and monitor the activities of oil explorers as well as education of the communities on the effects of bunkering near shoreline.

    Description: This study was carried out to determine the bioaccumulation of heavy metals in Clarias anguillaris and Parachanna africana from Lake Geriyo Yola, Nigeria using energy dispersive X-ray fluorescence (EDXRF) spectrophotometer. The results in (mg/kg, dry weight) showed different levels of Cr, Cu, Mn, Fe, Ni, Zn, and Pb in the two fish species. The order of heavy metals accumulated by C. anguillaris and P. africana are Cr〉Fe〉Zn 〉 Mn〉Cu〉Ni〉Pb and Ni〉Fe〉Zn〉Cu respectively. The levels of Cr, Mn and Ni in C. anguillaris and in Ni in P. africana were higher than WHO and FEPA recommended maximum permissible limits (MPL) in fish, while the levels of Zn, Cu and Pb were below the standards. The results suggest that Lake Geriyo has high pollution loads of these heavy metals in fishes and could pose a health hazards to man. Consequently, close monitoring of heavy metal loads in Lake Geriyo is recommended with a view to minimizing the risks to health of the population that depend on the lake for their water and fish supply.

A total of 52 live catfish (average weight 700.0~c7.0g) were used for the experiment. Ten freshly slaughtered fish samples each were selected for organoleptic assessment at 0, 4, 8 and 12 hours post-slaughter, while three fish samples each were selected for chemical and microbial analyses. Microbial load on fish samples increased significantly (P〈 0.05) with increase in length of delay after slaughter, LODAS. Bacteria isolated included Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Bacillus spp and Staphylococcus aureus. Percent protein and ash contents of fish samples increased with increasing LODAS, while moisture content decreased and lipid was not affected. It was observed that raw C. gariepinus retained most of its physical attributes up to 4 hours post-slaughter. These quality attributes except colour and odour of gills, deteriorated significantly (P 〈 0.05) at every successive four-hour post-slaughter interval. Significant negative correlation existed between LODAS and sensory quality of raw fish (eyes, r = -0.966, P 〈 0.05; gills, r = -0.980, P 〈 0.05; skin, r = -0.998, P 〈 0.01; and odour, r = -0.994, P 〈 0.01). This study established that quality of raw C. gariepinus deteriorated with increasing LODAS and that raw C. gariepinus was not totally unacceptable when delayed for 12 hours after slaughter at ambient temperatures.

    Description: A 24-month survey was conducted during the wet (May- August) and Dry (October ?April) season of 2004 and 2006 along eight economic fishing sites in Ondo State bearing Wetland, with the aim of determining the abundance, species diversity of some ornamental species thus promoting ecotourism potential and preventing the loss of these species in the area during and after exploitation. The study was carried out in 4 study zones namely Odigbo (S1), Ode-Aye (S2), Okitipupa (S3), and Ilaje ese-odo (S4) noted for active bitumen seepage. Fishing potential of the area was assessed using catch per unit effort method as well as physico chemical analysis of water samples obtained from designated sites in the area in accordance with AOAC methodology. Fish compositions were assessed using multifilament gillnet, of different sizes hanging from 38 mm to 178 mm. The results revealed that the area is blessed with 24 economic species of fishes belonging to 13 families which could boost the tourist potential of Ondo State. The percentage composition of families identified varies as follows: Ariidae (2.04%), Anabantidae (3.27%), Bagridae (6.36%), Channidae (4.32%), Characidae (10.62%) Cichlidae (45.65%) Clupeidae (3.94%), Clariidae (11.78%), Hepsetidae (0.95%), Mormyridae (7.42 %), Malapteruridae (1.13%), Schilbiidae (1.76%), Polypteridae (0.76%). The family Cichlidae was the most abundant in the area during the study period. The diversity of fish during the study varied with locations and season .The study showed higher fish population during the dry season than raining season and lower population in study zones highly polluted by bitumen seepages. The study emphasizes the need for sustainable resource management during bitumen exploitation.

    Description: The Niger Delta serves as the economic nerve centre of the Nigeria Federation with its vast oil deposits. However the question is how far has the coastal fisheries thrived in the Niger delta since the discovery of crude oil? Fishing is the predominant occupation in the coastal communities. The Niger Delta is home to Nigeria’s oil industry. However, this ‘blessing’ has become a challenge for the people of the Niger Delta. They have suffered environmental devastation, economic poverty, and constant conflict. This paper discusses issues and challenges facing fisheries development in Niger-Delta area of Nigeria.

    Description: Static bioassays were carried out in the laboratory for 96h to investigate the effect of Parateq a synthetic base mud on the fingerling of Orechromis niloticus and their microbial population. The fingerlings were exposed to different concentrations (0, 1000, 3000, 5000 and 9000Mg/l) of drilling fluid. Fish mortality data were recorded at 24, 48, 72 and 96h and analysed using Finney’s Probit Analysis method to calculate LC50 values (concentration of drilling fluid in water that will kill 50% of the fish population in 96 hours). The 96h LC50 was 2210Mg/l.The mortality increased with increase in concentration, while, the lethal times decreased as concentration increased. The bacterial biomass ranged from 1.59 x 108 to 6.0 x 106CFU/ml while fungal biomass ranged from1.0 x 103 to 2.1 x 104 CFU/ml. Results revealed that there was an increase in fungal biomass with increase in mud concentration and a decrease in bacterial biomass with increase in mud concentration.

    Description: A static bioassay method to determine the acute toxicity of the herbicide propanil to Oreochromis niloticus was investigated under Laboratory conditions for 96 hours exposure period. Concentrations of propanil used include: 0.0096ml/l, 0.0103ml/l, 0.011ml/l and 0.012ml/l respectively. The lethal concentration (LC50) value of propanil on fingerlings of Oreochromis niloticus was 0.0097ml/l for 96 hours of exposure. The regression equation for probit kill from propanil was found to be Y = 29.84 + 12.33* log conc. (r2 0.9951, Y = Probit kill). Fish showed various abnormal behaviours upon exposure to propanil. Immediate reaction was erratic swimming and tendency to jump out of the test bowl. Others include: restlessness, un-coordinated movement, vertical swimming, air gulping, equilibrium loss, a period of quiescence and eventually death.

    Description: In recent times there has been an upsurge in the culture of Tilapia in Nigeria resulting in increased demand for the fingerlings which is hardly satisfied. This is due to increasing demand for table size tilapia as food fish and under-sized tilapia in the fish meal and fish canning industries in Nigeria. Collection of Tilapia guineensis fingerlings from the wild, to augment hatchery production, has been the practice and this is subject to environmental fluctuations. Multivariate regression and correlation analyses of accumulated data were used to investigate the effects of changes in water quality parameters on abundance of fingerlings of Tilapia guineensis in a brackishwater habitat in Lagos. Dissolved oxygen (DO), salinity and secchi transparency were found to be the most dominant factors affecting the abundance of Tilapia guineensis fingerlings in the Lagos lagoon. Peak period of abundance was closely associated with period of low salinity (0.50%o to 5.60%o), which coincided with the period of low transparency and low DO in the rainy season. The correlation analyses of Tilapia guineensis fingerlings with the water quality parameters yielded the following correlation coefficients (r)- 0.598; (salinity); -0.644 (transparency); -0.710 (DO); -0.566; (temperature) and 0.129 (pH). The abundance of Tilapia guineensis fingerlings in the Lagoon was ultimately defined by a suitable regression equation. This result is expected to optimize the collection of fingerlings of Tilapia guineensis from the wild and boost food fish security in Nigeria and elsewhere.

    Description: The poor nature of most Agricultural processing practices in Nigeria have had adverse effect on our environment, and our aquatic resources are of no exception. This study was conducted to ascertain the median lethal concentration of the effluent within the 96 hours period and also to ascertain the extent of damage on some of the histological characteristics of the Clarias gariepinus juveniles. Juveniles of the Clarias gariepinus (mean weight 30g) were exposed to varied concentrations of the locust bean effluent under the standard laboratory conditions. Data on mortality corresponding to the various concentrations were subjected to the probit and logit transformations and used to calculate the LC50 graphically. The result shows the toxicity of the locust bean effluent to Clarias gariepinus juveniles as 0.089mg/L (treatment 4) during the period of study. Exposure to both the acute and subletheal concentrations resulted in a number of physiological dysfunction of the test fish. Observation of the fish under the tests revealed unbalanced swimming patterns loss of reflex, rapid opercular movements and gasping for air. Histopathological examination of the gill and liver of the treated fish showed signs of damage, ranging from Hypoxia, lesions, necrosis, fibrosis cell stasis and hyperplasia at the sublethal levels.

    Description: A total number of 166 specimens of Mugil cephalus caught from Epe Lagoon (low brackish/ freshwater) were examined for food and feeding habit and biometric features from November 2006 ? May 2007. The food of the species consisted mainly of algae (Bacillariophyta, Cyanophyta, Chlorophyta and Pyrrophyta) and detritus. The size range of fish examined were 12.4 ? 27.0cm (standard length) while the weight ranged from 22.40 ? 308.00g. The mean values of the biometric characters of Mugil cephalus did not reflect wide variations. The population dominant cohort in the lagoon represents the harvestable and marketable representative for a sustainable fishery and is a strong indication of potential for freshwater culture of this marine species.

    Description: This study investigated the fish diversity of Eko ? Ende and Owalla reservoirs, which are within the Osun river system in South West, Nigeria with a view to document biodiversity information needed for conservation and sustainable fisheries. Fish samples were collected monthly from the two reservoirs for one year, using a battery of multifilament gill nets. The data collected from each reservoir was analyzed for fish diversity. Information obtained on the forage / carnivore (F/C) ratio of fishes in each reservoir was used in measuring and comparing the ecological balance of the reservoirs. The results showed that eighteen fish species representing 16 genera and 10 families were identified in Eko ? Ende, while 17 fish species in 15 genera and 10 families were identified in Owalla during the period of study. Sixteen species (representing 84.2% of the total number of fish species) were common to both reservoirs and they were both dominated by Cichlids. Eko ? Ende Reservoir had greater fish diversity than the Owalla Reservoir. Shannon ? Weiner (H') index of fish diversity from Eko ? Ende reservoir was 2.37 while that from Owalla reservoir was 2.10. The forage / carnivore (F/C) ratios of the fishes from the two reservoirs showed that Eko ? Ende reservoir (F/C = 1.98) is ecologically balanced, while Owalla reservoir (F/C = 0.92) is not Owalla reservoir had a higher population of Hemichromis fasciatus (a predatory species). This reservoir also had more intensive fishing activities than the smaller Eko ? Ende reservoir. The study concludes on the need for a participatory research to alleviate the problem of ecological imbalance of fish species in Owalla reservoir.

    Description: African snakehead, Parachanna obscura is being considered as an emerging aquaculture candidate in Nigeria. The species is very palatable and has a good fillet quality. Study was conducted on the proximate composition of the species from Cross River, Nigeria. Samples of snakehead were analyzed for protein, fat, moisture, crude fibre and ash contents. The protein content of the species ranged from 21.03-22.03 with mean value of 21.5%. The fat content ranged from 17.1-17.4% with a mean value of 17.2 %. Moisture content ranged from 51.1-52.0 % with a mean value of 51.7%. Ash and crude fibre contents were very low. The protein content of Parachanna obscura compares favourably with that of other members of the family Channidae. The fat content is exceptionally high, making the species a good healing and recuperating agent for post-natal and post-operation patients. We strongly recommend the culture of Parachanna obscura in Nigeria and its meal for growing children.

    Description: Study was conducted to investigate lipid profile and metabolites in deformed (lost one or both pectoral fins) and healthy (both pectoral fins intact) African mud catfish C. gariepinus using three groups of adults male and female with a mean weight and standard length of 822.17~c 48.75g and 42.55~c.26cm respectively. The fish were allotted in replicates to 5000m capacity tanks based on the presence or absence of pectoral fins. 1mL blood was drawn from caudal peduncle of each fish by means of disposable sterile syringe and centrifuged at 1000rpm for 20min at 40C. Cholesterol and total protein were determined using the cholesterol FL (CT F400CH) and total protein (TP 0500CH) kits. Serum albumin and globulin concentrations were determined following methods described by Tietz (1995) and Buckley et al., (1976) while total serum bilirubin concentration was measured as outlined by AACC (American Association of Clinical Chemistry). Results indicate that male fish had relatively higher amount of triglyceride while female fish had higher amounts of cholesterol, reduction in globulin of the deformed fish, reduction in the concentrations of albumin in healthy fish, increase in total protein and globulin levels and high urea concentrations. No total bilurubin was detected in any of the fish sampled thus an indication of good liver function which means there was no liver dysfunction or liver damage in the fishes. It is evident therefore that abnormal fish can still perform better if they are given intense management because of the variability in their blood constituents with the normal fishes which is used to assess their health is minimal.
