    Caso de Estudio No. 2: Estado de la pesquería de la langosta espinosa (Panulirus argus) y su relación con factores ambientales y antrópicos en Cuba. (2011)
    Instituto de Oceanología | Cuba
    Details
    Publication Date: 2021-05-19
    Description: Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima legal de captura a partir de 2004. Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller Regional sobre la Evaluación y la Ordenación de la Langosta Común del Caribe en septiembre 2006 (Puga et al, 2006; FAO, 2007), donde se reconoció por la comunidad científica especializada que la pesquería de langosta cubana se encontraba bien manejada y plenamente explotada (no sobre- explotada) y se concluyó que además de la mortalidad por pesca, otros factores ajenos al sector pesquero estaban produciendo afectaciones en la abundancia del recurso, al causar daños al hábitat 1 en zonas de cría, influyendo negativamente por esta vía sobre el reclutamiento y la producción de langostas. Entre estos aspectos para Cuba se señalaron: la mayor frecuencia e intensidad de huracanes durante el último decenio, el desarrollo de las zonas costeras, la construcción de presas en las cuencas de captación de los ríos y de carreteras en el Archipiélago Sabana-Camagüey comunicando la isla principal con los cayos y los cayos entre si (pedraplenes).

    Técnicas de elaboración y "Curado" de cuerdas de Currican para la pesca en Taganga/Santa Marta, Colombia (2011)
    Santa Marta (Colombia), INVEMAR
    Details
    Publication Date: 2021-05-19
    Description: El presente artículo da una descripción detallada de la elaboración y del "curado" de cuerdas de curricán, utilizadas anteriormente para la pesca en Taganga, un pueblo pescador en la costa norte de Colombia. Antes del "curado", estas cuerdas de fibras de algodón y de fabricación industrial, eran o destorcidas o torcidas a mano nuevamente, o tensionadas y envueltas con una cuerda más delgada del mismo material. El "curado" que siguió a estas operaciones se efectuó tanto en una cocción de corteza de las raíces zanconas de mangle, y/o por medio de un frote de estas cuerdas con los hypocotylos del mismo árbol (Rhizophora manglr). Por medio de las técnicas aquí descritas, los pescadores aspiraban a aumentar la resistencia de sus aparejos de pesca en el agua de mar.
    Description: The present paper gives a detailed description of the elaboration and curing of curricán Unes, formerly used as fishing lines in Taganga, a small fishing village on the northem coast of Colombia. These lines, made of cotton fibers and produced industrially, were disassembled and then retwisted by hand, or tightened and then carefully covered with a thinner string of the same material. The curing {"curado") that followed these operations was achieved by immersion of the lines into a boiled infusión of the bark of the prop roots of mangroves (Rhizophora mangle) and/or a rinsing with the hypocotyls of the same trees. By means of the techniques mentioned, the fishermen sought to improve the resistance of their fishing gear to sea water.

    Observations on the biology of the redlip Blenny, Ophioblennius atlanticus (Pisces: Blenniidae) on the Colombian Coast of the Caribbean (2011)
    Santa Marta (Colombia), INVEMAR
    Details
    Publication Date: 2021-05-19
    Description: During a 3 week study, a total of 55 individuals of the redlip blenny (Ophioblennius atlanticus) were observed for at least two 15-minute periods, and several for ten of such periods. The sizes of their territories were estimated, the color pattern of each specimen an intra and interspecific interactions were recorded. The mean territory size of the redlip blenny in the study area appeared to be greater than that of these blennies studied in Curacao and Barbados by NURSALL (1977), the difference reflecting perhaps different methods of identifying the territories or a lower density of O. atlanticus in the Santa Marta área. Territories did not appear to be as consistently defended at the study area as at Barbados/Curacao and our impression ¡s that individuals holding large territories are less likely to defend their borders. It seems possible that light colored individuals are protected by their coloration from attack by dark colored territory owners. In territorial defense the redlip blennies grabbed each other tighthy by the mouth and struggled in this position repeatedly for about 15 seconds. Interspecific antagonism was common in the present study, the redlip blennics defended their territory frequently against Eupomacentrus dorsopunicans or E. partitus.
    Description: Durante un estudio de tres semanas, un total de 5 i individuos del bií'nido Ojih'toblcnnius atlnniicur. fueron observados por lo menos durante dos períodos de 1 í minutos para cada individuo y en algunos casos hasta por 10 de estos periodos. Se estimó el área de sus respectivos territorios y se tomó notí de los patrones de coloración de cada espécimen y de las relaciones intra e interespecificas de ellos. El tamaño promedio del territorio de estos blénidos resultó ser mayor que el de los respectivos territorios estudiados por NURSALL (1977) en Curacao y Barbados. Esta diferencia posiblemente se debe a un método diferente de definir los territorios o refleja una densidad menor de la población de O. aílanticus en Santa Marta, Los territorios del área fueron defendidos con menor intensidad a como lo fueron los de Barbados/ Curacao y es nuestra impresión que individuos ocupando un territorio extenso tienden a defender sus límites en menor grado. El color claro de algunos individuos probablemente los protege de agresiones por parte de individuos de color oscuro. En el acto de defensa territorial intraespecífica, los blénidos se agarran por sus bocas y se sacuden mutuamente durante aproximadamente 15 segundos , pudiéndose repetir esti varias veces. Con frecuencia se observarondefensas de los territorios dirigidas hacia los peces doncella Eupomacentrus dorsopunicnas y E. partitus.

    The condition factor of Mugil incilis Hancock (Pisces: Mugilidae) and its seasonal changes in the Cienaga Grande de Santa Marta (Colombia) (2011)
    Santa Marta (Colombia), INVEMAR
    Details
    Publication Date: 2021-05-19
    Description: Se ha estudiado la variación anual de la condición de la lisa Mugil incilis Hancock en la Ciénaga Grande de Santa Marta (CGSM), la mayor laguna costera del Caribe Colombiano, haciendo énfasis en la influencia ejercida por factores ambientales como la salinidad, la temperatura y la transparencia de las aguas sobre la condición de esta especie de Mugilidae. Las diferencias estacionales observadas en la condición de M. incilis están evidentemente relacionadas con su desarrollo gonadal y dependen de la disponibilidad de alimento. La dieta de M. incilis se basa en detritos y su suministro de alimento parece ser muy afectado por el aporte fluvial a la CGSM, el cual es también responsable de los cambios en la salinidad de la laguna, esto explica la relación inversa (r = -0.82) hallada entre la salinidad y la condición de M. incilis expresada por C = 0.9949 - 0.0057 S(°/oo). La variación anual de la salinidad sigue un patrón rítmico de cambios estacionales, no precisamente "in situ", sino en regiones continentales distantes: las cabeceras de los tributarios de la CGSM. Estas lisas desovan en aguas del Caribe adyacente a la CGSM y su período de migración (dic-marzo) comienza con su mejor condición física, y retornan a sus áreas de alimentación en la CGSM 2 a 4 semanas después, hasta el final de la migración, con su condición mínima ya que al parecer estas lisas no se alimentan durante su migración de desove. No se observaron cambios relacionados con las variaciones de la temperatura. Las aguas más turbias coincidieron con los sitios de alimentación de M. incilis.
    Description: The annual variation in condition of the mullet Mugil incilis Hancock has been studied in the Ciénaga Grande de Santa Marta (CGSM). The largest coastal lagoon on the Colombian Caribbean, with emphasis on the influence of such environmental factors as salinity, temperature and transparence of the waters on the condition of this species of Mugilidae. Seasonal differences observed in condition of M. incilis are evidently related to gonadal development and depend on food availability. The diet of M, incilis is based on detritus and its food supply seems to be very influenced by river discharge which also accounts for the salinity changes in the lagoon. this explains the in verse correlation (r = -0.82) found between salinity and condition of the mullets expressed as C = 0.9949 - 0.0057 S (°/oo). Annual salinity variation follows a rhythmic pattern of seasonal changes. not precisely "in situ", but in distant continental regions: the headwaters of the tributarles of the CGSM. These mullets spawn in Caribbean waters adjacent to the CGSM and their migración period (Dec-March) begins with their best physical condición, returning to their feeding áreas in the CGSM 2 or 4 weeks lacer, until the end of the migración, with their lowest condition since these mullets apparently do not feed at all during the spawning migration. No change related to temperature variations was observed. and turbid waters were the rule in M. incilis feeding sites.

    Projet d'aménagement des stocks pélagiques partagés : Cas des pêcheries de mulets et de courbines en Mauritanie et au Sénégal (2011)
    Details
    Publication Date: 2021-01-30
    Description: En Afrique de l'Ouest, la zone littorale et ses ressources représentent une composante essentielle pour le développement. Près de 60% de la population est concentrée à moins de 20 km des côtes . La part des ressources halieutiques dans l'alimentation des populations est très importante et croissante. Au Sénégal par exemple, elles contribuent jusqu'à 70% des apports en protéines. A cela s'ajoute le poids socio-économique très important de la pêche en général et de la pêche artisanale en particulier devenue l'un des secteurs les plus stratégiques pour l'économie nationale en Mauritanie notamment. Le Cadre Stratégique de Lutte contre la Pauvreté du Gouvernement Mauritanien considère que : "compte tenu des possibilités qu'elle offre en terme de création d'emplois et de sécurité alimentaire notamment pour les populations pauvres, mais également de génération de recettes en devises, la pêche artisanale revêt une grande priorité, un plan décennal de développement lui sera consacré ".

The definitive version was published in Aquatic Conservation: Marine and Freshwater Ecosystems 21 (2011): 17-27, doi:10.1002/aqc.1158
    Description: 1. Interactions between cetaceans and fishing activity in the Archipelago of the Azores were examined using information contained in grey literature and previously unpublished data collected by observer programmes and research projects from 1998 to 2006. Together with a brief description of the economics, gear, fishing effort, and past and ongoing monitoring projects, levels of cetacean bycatch and interference were reported for each major fishery. 2. Cetaceans were present in 7% (n=973) and interfered in 3% (n=452) of the fishing events monitored by observers aboard tuna-fishing vessels. Interference resulted in a significantly higher proportion of events with zero catches but it was also associated with higher tuna catches. 3. There was a decreasing trend in the proportion of tuna-fishing events with cetacean presence or interference throughout this study, as well as a reduction in the estimates of dolphins captured annually by the whole fleet. 4. Observers reported cetacean depredation in 16% of the sets for demersal species and in 2% of the sets for swordfish. Cetacean presence and depredation were associated with higher overall catches and higher catches per unit effort in demersal fisheries. Bottlenose dolphins (Tursiops truncatus) were responsible for most depredation events in demersal fisheries, whereas in the swordfish fishery, depredation was associated with the presence of killer whales (Orcinus orca). There were no reports of cetacean bycatch in these fisheries. There were also no reports of cetaceans interacting in the experimental deep-sea fisheries that were examined. 5. Available data suggests that levels of interaction between cetaceans and Azorean fisheries are generally low and that the economic impact of cetacean interference is probably small. However, for several traditional fisheries there are no accurate data to determine levels of cetacean interaction. We recommend that existing observer programmes be expanded to increase observer coverage of the demersal and swordfish fisheries and allow monitoring of other existing and emerging fisheries.

    Multiple genetic stocks of longfin squid Loligo pealeii in the NW Atlantic : stocks segregate inshore in summer, but aggregate offshore in winter (2011)
    Inter-Research
    Details
    Publication Date: 2022-05-26
    Description: Author Posting. © Inter-Research, 2006. This article is posted here by permission of Inter-Research for personal use, not for redistribution. The definitive version was published in Marine Ecology Progress Series 310 (2006): 263-270, doi:10.3354/meps310263.
    Description: The longfin squid Loligo pealeii is distributed widely in the NW Atlantic and is the target of a major fishery. A previous electrophoretic study of L. pealeii was unable to prove genetic differentiation, and the fishery has been managed as a single unit stock. We tested for population structure using 5 microsatellite loci. In early summer (June), when the squids had migrated inshore to spawn, we distinguished 4 genetically distinct stocks between Delaware and Cape Cod (ca. 490 km); a 5th genetic stock occurred in Nova Scotia and a 6th in the northern Gulf of Mexico. One of the summer inshore stocks did not show genetic differentiation from 2 of the winter offshore populations. We suggest that squids from summer locations overwinter in offshore canyons and that winter offshore fishing may affect multiple stocks of the inshore fishery. In spring, squids may segregate by genetic stock as they undertake their inshore migration, indicating an underlying mechanism of subpopulation recognition.

    Transient dynamics of an altered large marine ecosystem (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-29
    Description: Overfishing of large-bodied benthic fishes and their subsequent population collapses on the Scotian Shelf of Canada's east coast and elsewhere resulted in restructuring of entire food webs now dominated by planktivorous, forage fish species and macroinvertebrates. Despite the imposition of strict management measures in force since the early 1990s, the Scotian Shelf ecosystem has not reverted back to its former structure. Here we provide evidence of the transient nature of this ecosystem and its current return path towards benthic fish species domination. The prolonged duration of the altered food web, and its current recovery, was and is being governed by the oscillatory, runaway consumption dynamics of the forage fish complex. These erupting forage species, which reached biomass levels 900% greater than those prevalent during the pre-collapse years of large benthic predators, are now in decline, having outstripped their zooplankton food supply. This dampening, and the associated reduction in the intensity of predation, was accompanied by lagged increases in species abundances at both lower and higher trophic levels, first witnessed in zooplankton and then in large-bodied predators, all consistent with a return towards the earlier ecosystem structure. We conclude that the reversibility of perturbed ecosystems can occur and that this bodes well for other collapsed fisheries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frank, Kenneth T -- Petrie, Brian -- Fisher, Jonathan A D -- Leggett, William C -- England -- Nature. 2011 Jul 27;477(7362):86-9. doi: 10.1038/nature10285.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ocean Sciences Division, Bedford Institute of Oceanography, P.O.

    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〉
