    North West Water Authority
    Publication Date: 2013-03-22
    Description: This is the report from the Central Area Fisheries Advisory Committee meeting, which was held on the 31st March, 1982. It includes information on the River Leven smolt rearing scheme, the annual report on match fishing at Skerton and Mitton fisheries, and the report by the area fisheries officer on fisheries activites from September 1981 to January 1982. The report covers information on river conditions and fishing, migratory fish movements, an update on the work at Middleton hatchery, Salmon cages on the Leven and Langcliffe hatchery. It also includes information on fish disease, fish mortalities, management work and monthly salmon and sea trout catches for rod, line, nets and fixed engines for the 1981 season. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

    Description: The Channel Islands—sometimes called the Galapagos of North America—are known for their great beauty, rich biodiversity, cultural heritage, and recreational opportunities. In 1980, in recognition of the islands’ importance, the United States Congress established a national park encompassing 5 of California’s Channel Islands (Santa Barbara, Anacapa, Santa Cruz, Santa Rosa, and San Miguel Islands) and waters within 1 nautical mile of the islands. In the same year, Congress declared a national marine sanctuary around each of these islands, including waters up to 6 nautical miles offshore. Approximately 60,000 people visit the Channel Islands each year for aquatic recreation such as fishing, sailing, kayaking, wildlife watching, surfing, and diving. Another 30,000 people visit the islands for hiking, camping, and sightseeing. Dozens of commercial fishing boats based in Santa Barbara, Ventura, Oxnard, and other ports go to the Channel Islands to catch squid, spiny lobster, sea urchin, rockfish, crab, sheephead, flatfish, and sea cucumber, among other species. In the past few decades, advances in fishing technology and the rising number of fishermen, in conjunction with changing ocean conditions and diseases, have contributed to declines in some marine fishes and invertebrates at the Channel Islands. In 1998, citizens from Santa Barbara and Ventura proposed establishment of no-take marine reserves at the Channel Islands, beginning a 4-year process of public meetings, discussions, and scientific analyses. In 2003, the California Fish and Game Commission designated a network of marine protected areas (MPAs) in state waters around the northern Channel Islands. In 2006 and 2007, the National Oceanic and Atmospheric Administration (NOAA) extended the MPAs into the national marine sanctuary’s deeper, federal waters. To determine if the MPAs are protecting marine species and habitats, scientists are monitoring ecological changes. They are studying changes in habitats; abundance and size of species of interest; the ocean food web and ecosystem; and movement of fish and invertebrates from MPAs to surrounding waters. Additionally, scientists are monitoring human activities such as commercial and recreational fisheries, and compliance with MPA regulations. This booklet describes some results from the first 5 years of monitoring the Channel Islands MPAs. Although 5 years is not long enough to determine if the MPAs will accomplish all of their goals, this booklet offers a glimpse of the changes that are beginning to take place and illustrates the types of information that will eventually be used to assess the MPAs’ effectiveness.

    Description: In 1999 trap fishermen and environmental groups testified at a Fish and Game Commission (Commission) meeting that they were concerned about high levels of bycatch in the spot prawn trawl fishery. Environmental representatives requested that the Commission consider adopting regulations that would phase out the spot prawn trawl fishery by 2004 and convert spot prawn trawl permits to spot prawn trap permits. Also in 1999 the Department reported to the Commission the results of six observed spot prawn trawl tows in March 1999, including the ratio of weight of finfish bycatch to weight of spot prawns (7.4 to 1). Based primarily on the above factors, the Commission initially directed the Department to develop, as part of a package of regulatory proposals for the spot prawn trap and trawl fisheries, a proposal to phase out the spot prawn trawl fishery and convert trawl permits to trap permits. Subsequently the Department recommended that, instead of phasing out the spot prawn trawl fishery, information on the relative amount and type of bycatch in the trawl and trap fisheries be determined through an on-board observer program. An observer fee structure was proposed and adopted, and an observer program was in effect for all vessels landing spot prawns from July 14, 2000 to March 31, 2001. Vessels were required to purchase and possess a spot prawn observer fee permit in order to take and land spot prawns. Funds from the program were used to support on board observers and to digitize and analyze the data. Some fishing trips were observed after the requirement for the observer fee had expired. A total of 86 spot prawn trawl tows (71 from northern California-based vessels and 15 from southern California- based vessels) was observed on nine vessels during the period September 26, 2000 to September 19, 2001. Observed vessels fished from the ports of Fort Bragg, San Francisco, Monterey, Morro Bay, and Ventura. For northern California trawl vessels, the top five finfish species observed in the bycatch, in decreasing frequency of occurrence, were Pacific hake (whiting), Dover sole, sablefish, English sole, and splitnose rockfish, comprising 53.9% of all fishes by weight. Twenty-eight species of rockfishes were observed, comprising 28.1% by weight of all fishes. The weight ratio of total finfish bycatch to total spot prawn catch from all tows combined was 7.5 to 1. The ratio of total rockfish bycatch to total spot prawn catch was 2.1 to 1. For southern California trawl vessels, the top five finfish species observed in the bycatch, in decreasing frequency of occurrence, were Pacific sanddab, Pacific hake, slender sole, shortbelly rockfish, and Dover sole, comprising 83.1% of all fishes by weight. Fifteen species of rockfishes were observed, comprising 8.8% by weight of all fishes. The ratio of total finfish bycatch to total spot prawn catch from all tows combined was 17.7 to 1. The ratio of total rockfish bycatch to total spot prawn catch was 1.5 to 1. The ratio of total trawl bycatch, including invertebrates, to spot prawn catch was 8.8 to 1 in northern California and 20.6 to 1 in southern California. The National Marine Fisheries Service has determined the following rockfish species to be overfished and require rebuilding: bocaccio, canary, cowcod, darkblotched, widow, and yelloweye. Bocaccio, cowcod, darkblotched, and widow rockfishes were observed in multiple tows, and yelloweye and canary each were observed in a single tow. In general, the relative abundance of overfished rockfish species was low compared with other finfishes. However, expansions by weight of finfishes from observed tows to all spot prawn tows, based on the ratio of total to observed spot prawn landings, indicated that the estimated total bycatch of overfished rockfishes was significant in terms of allowable catch levels (optimum yields) established by the Pacific Fishery Management Council (Council). Other overfished species observed in the sampled catch including Pacific hake (whiting) and lingcod. Results from these trawl observations relative to bycatch levels were consistent with the few previous studies conducted. That is, the total observed bycatch in the trawl fishery was more than four times that of spot prawns by weight. A total of 27 trap vessels paid the required observer fee, and 23 of these landed spot prawns during the period in which the observer fee was required. Passage was secured on 16 of these 23 vessels for observations of bycatch. An additional vessel that had not paid the fee was sampled after the fee requirement period had expired. A total of 262 spot prawn trap strings (88 from northern California vessels and 174 from southern California vessels) was observed from 16 vessels during the study. Observed vessels fished out of the ports of Monterey, Morro Bay, Channel Islands Harbor, Ventura, Terminal Island, Newport Beach, Dana Point, Oceanside, and San Diego. For northern California trap vessels, the top five finfish species observed in the bycatch, in decreasing frequency of occurrence, were sablefish, rosethorn rockfish, greenblotched rockfish group, spotted cusk eel, and filetail catshark, comprising 77.7% of all fishes by weight. Seventeen species of rockfishes were observed, comprising 25.5% by weight of all fishes. The ratio of total finfish bycatch to total spot prawn catch from all strings combined was 0.15 to 1. The ratio of total rockfish bycatch to total spot prawn catch was 0.04 to 1. For southern California trap vessels, the top five finfish species observed in the bycatch, in decreasing frequency of occurrence, were lingcod, greenblotched rockfish group, threadfin sculpin, sablefish, and swell shark, comprising 66.4% of all fishes by weight. Twenty-two species of rockfishes were observed, comprising 32.5% by weight of all fishes. The ratio of total finfish bycatch to total spot prawn catch from all strings combined was 0.22 to 1. The ratio of total rockfish bycatch to total spot prawn catch was 0.07 to 1. The ratio of total trap bycatch, including invertebrates, to spot prawn catch was 1.0 to 1 in northern California and 2.0 to 1 in southern California. Most invertebrates and many fish species other than rockfishes could be returned to the water alive. Overfished rockfish species were observed infrequently, and expansions of observed bycatch data to all trap strings yielded relatively low total estimated bycatch weights for these species. In northern California, the relative amount of bycatch for all finfishes and rockfishes was 50 and 52 times greater, respectively, in the trawl fishery compared with the trap fishery. In southern California, the relative amount of bycatch for all fishes and rockfishes was 80 and 21 times greater, respectively, in the trawl fishery compared with the trap fishery.

    Description: Two sources of historical landing data from California's commercial passenger fishing vessel (CPFV) fleet were examined to: 1) assess status and content of each archival data source, 2) identify reporting differences, and 3) evaluate potential usefulness of the data for enhancing resource assessment. Current and historical CPFV logbook data collected by California Department of Fish and Game are described with respect to status, content, and approximate cost of recovering historical data (1936-78) to electronic format. CPFV landing data available from Los Angeles Times, archived in libraries since 1959, are similarly described. CPFV logbook data were compared with observer data from 1985-89 to evaluate accuracy of logbook records. Comparison of catch and effort for major species targeted by southern California CPFV anglers revealed significant relationships between reported and observed catch rates for six of ten species examined. Agreement of catch rate trends validates use of logbook data for measuring relative changes in catch and effort for these sport fish species. Direct comparisons of landings data from CPFV logs and Los Angeles Times fish reports were made for years in which Times data are already available in electronic database format, including 1959, 1967, 1975, 1983, 1991, and 1992. Comparisons of total landings by species among years revealed strong correlations between the two sources for those species (e.g., California barracuda, yellowtail, bonito) most heavily targeted over the entire period. Other species, such as California sheephead, spotted scorpionfish, and ocean whitefish, were underreported or not reported by the Times until recently. Comparison of port-wide total landings of all species (1983, 1991, 1992) revealed varied reports of total catch (all species) between sources among ports and years. Times-logbook landing report comparisons were highly correlated for Los Angeles area ports (r2=0.956), but were also most different in absolute number, with Times reports being an average of 48% higher than logbook totals. Comparison of species landings by port in 1992 revealed additional port-wide differences in reporting between both sources. Historical CPFV logbook records have higher spatial resolution (catch location as opposed to port of landing), span a greater period, and will be cheaper to recover into electronic database format than Times fish reports. Historical Times data have higher temporal resolution (daily v. monthly), but II cost approximately $165,000 to recover as opposed to $11 ,000 for logbook data summaries covering a longer period. Strong correlation between the two sources shows usefulness of Times data for tracking real-time changes in sport catch in southern California. (53pp.)

    Description: Adult steelhead (Oncorhynchus mykiss irideus) scales were analyzed from eight fall-run, two spring-run, and one winter-run stocks within the Klamath-Trinity River system, from 1981 through 1983, to provide basic information on age, growth, and life history. The higher degree of half-pounder occurrence of upper Klamath River steelhead stocks (86.7 to 100%) compared to Trinity River steelhead stocks (32.0 to 80.0%) was the major life history difference noted in scale analysis. Early life history was similar for all areas sampled with most juveniles (86.4%) remaining in freshwater during the first two years of life before migrating to sea. Repeat spawning ranged from 17.6 to 47.9% for fall-run, 40.0 to 63.6% for spring-run, and 31.1% for winter-run steelhead. Mean length of adults at first spawning was inversely related to percent half-pounder occurrence in each stock. Ages of returning spawners, back calculated lengths at various life stages, and growth information are presented. (PDF contains 22 pages)

    Description: The California Department of Fish and Game's Natural Stocks Assessment Project (NSAP) collected water quality data at high tides on a monthly basis from February 1991 to October 1994, and during low tides from March 1992 to June 1994 in the Klamath River estuary to describe water quality conditions. NSAP collected data on water temperature, dissolved oxygen, salinity, depth of saltwedge, and Klamath River flow. Klamath River flows ranged from 44.5 cubic meters per second (1570 cfs) in August 1994 to 3832.2 cubic meters per second (135,315 cfs) in March 1993. Saltwater was present in the estuary primarily in the summer and early fall and generally extended 2 to 3 miles upstream. Surface water temperatures ranged from 6-8° C in the winter to 20-24° C in the summer. Summer water temperatures within the saltwedge were generally 5 to 8° C cooler than the surface water temperature. Dissolved oxygen in the estuary was generally greater than 6 to 7 ppm year-round. A sand berm formed at the mouth of the river each year in the late summer or early fall which raised the water level in the estuary and reduced tidal fluctuation so that the Klamath estuary became essentially a lagoon. I hypothesize the formation of the sand berm may increase the production of the estuary and help provide favorable conditions for rearing juvenile chinook salmon.

    Description: This report covers the 37th annual inventory of chinook salman, Oncorhynchus tshawytscha, spawner populations in the Sacramento-San Joaquin River system.-It is a compilation of reports estimating the fall-, winter-, late-fall-, and spring-run salmon spawner populations for streams which were surveyed. Estimates were made from counts of fish entering hatcheries and migrating past dams, froro surveys of dead and live fish and redds on spawning areas, and from aerial counts. The estimated 1989 total escapement of chinook salmon in the Central Valley was 205,990 fish. This total consisted of 181,864 fall-, 12,171 spring-, 539 winter-, and 11,416 late-fall-run spawners. All of the spring-, late-fall-, and winter-run salmon were estimated to be in the Sacramento River system, while 3,493 fish of the fall run were in the San Joaquin River system. Due to decreases of spawner populations in most Central Valley tributaries, the total 1989 salmon stock was 32% lower than in 1988; however, late-fall salmon in the upper Sacramento River had a run size similar to that of 1988. The winter run in the mainstem Sacramento River was at a record low level. (PDF contains 44 pages.)

    Description: Four groups of fin clipped brown trout (Salmo trutta) fingerlings were planted in Hot Creek over a six year period. Survival and growth were estimated by fall and/or spring mark-and-recapture surveys. Yield to the angler for two of the tour groups stocked was estimated by stratified random creel surveys. Fingerling survival from the midsummer stocking period to fall averaged 51 %. Overwinter survival from young-of-the-year to yearling fish averaged 49%. Angler harvest of two groups of fingerlings stocked at densities of 16,082 fish/mile averaged 1,704 trout/mile (10.6%) and 194 lbs/acre. Abundant cover and microhabitat suitable tor young trout, ice-free winters, and rapid growth were factors viewed as contributing to high yields. Results do not suggest a change is needed in the general policy of not stocking brown trout fingerlings in California streams. Results do show that fingerlings stocked in Hot Creek, and presumably other productive streams with abundant cover, can effectively fill a void created by limited recruitment.

    Description: This report covers the 39th annual inventory of chinook salman, Oncorhynchus tshawytscha, spawner populations in the Sacramento-San Joaquin River system." It is a compilation of reports estimating the fall-, winter-, late-fall-, and spring-run salman spawner populatiens fer streams which were surveyed. Estimates were made from counts of fish entering hatcheries and migrating past dams, from surveys of dead and live fish and redds on spawning areas, and from aerial counts. The estimated 1991 total escapement of chinook salmon in the Central Valley was 147,080 fish. This total consisted of 132,571 fall-, 5,921 spring-, 190 winter-, and 8,398 late-fall-run spawners. All of the spring-, late-fall-, and winter-run salmon were estimated to be in the Sacramento River system, while 1,176 fish of the fall run were in the San Joaquin River system. Spawner populations in all individual tributaries (except the American River) and the Sacramento River mainstem were lower than in 1990; but it should be noted that fall run populations in the Feather and Yuba rivers, two of the larger tributaries, were not surveyed that year. The winter run in the mainstem Sacramento River was at a record low level. (PDF contains 42 pages.)

    Description: Silver King Creek, Alpine County, is the native range of the Federally-threatened Paiute cutthroat trout, Oncorhynchus clarki seleniris. Paiute cutthroat currently inhabit Coyote Valley and Corral Valley creeks, which are tributaries to Silver King Creek below Llewellyn Falls, and also Silver King Creek and tributaries aboye Llewellyn Falls. Rainbow trout, O. mykiss, were introduced into the basin during 1949 and became hybridized with Paiute cutthroat. Chemical treatments attempted by the California Department of Fish and Game (CDFG) in 1964 and 1976 failed to eliminate hybrid trout. A chemical treatment project was again conducted by the CDFG from 1991 through 1993 to eliminate hybrid trout from within the range of Paiute cutthroat. This report presents a summary of events for the first two years of the Silver King Paiute Cutthroat Trout Restoration Project; a more thorough analysis is made of the third and final year of the project.

    Description: Sediment sampling was used to evaluate chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) spawning habitat quality in the South Fork Trinity River (SFTR) basin. Sediment samples were collected using a McNeil-type sampler and wet sieved through a series of Tyler screens (25.00 mm, 12.50 mm, 6.30 mm, 3.35 mm, 1.00 mm, and 0.85 mm). Fines (particles 〈 0.85 mm) were determined after a l0-minute settling period in Imhoff cones. Thirteen stations were sampled in the SFTR basin: five stations were located in mainstem SFTR between rk 2.1 and 118.5, 2 stations each were located in EF of the SFTR, Grouse Creek, and Madden Creek, and one station each was located in Eltapom and Hayfork Creeks. Sample means for fines(particles 〈 0.85 mm) fer SFTR stations ranged between 14.4 and 19.4%; tributary station sample mean fines ranged between 3.4 and 19.4%. Decreased egg survival would be expected at 4 of 5 mainstem SFTR stations and at one station in EF of SFTR and Grouse Creek where fines content exceed 15%. Small gravel/sand content measured at all stations were high, and exceed levels associated with reduced sac fry emergence rates. Reduction of egg survival or sac fry emergence due to sedimentation in spawning gravels could lead to reduced juvenile production from the South Fork Trinity River. (PDF contains 18 pages.)

    Description: Cluster analysis was evaluated as a classification technique to group fishing locations based on similarities in species catch-per-unit-effort (CPUE) data obtained through on board sampling. Catch data from the Monterey Bay area Commercial Passenger Fishing Vessel (CPFV) hook-and-line fishery were used. The analysis was designed to define potential fishery management units, refine estimation of species CPUE, and evaluate fish length data for the most commonly caught species in the CPFV fishery. Results produced similar location groups for two separate classifications of the more abundant species caught in the fishery, one based on midwater schooling species and a second based on benthic species. Location groups represented distinct contiguous geographic areas that appear to be strongly related to specific depth ranges and possibly other environmental variables. The differences in species composition among location groupings were distinct but apparently gradual, with no sharp species assemblage boundaries that represented clear divisions between specific ecological communities. Many species appeared to be distributed independently along depth gradients. Suggestions are given to improve the techniques used in future grouping of fishing locations. (46pp.)

    Description: Bolsa Chica Artificial Reef (BCAR) was constructed in November 1986 with 10,400 tons of concrete rubble and eight concrete and steel barges. Prior to any additional augmentation of BCAR, the u.s. Army Corps of Engineers and the California Coastal Commission required the California Department of Fish and Game (CDFG) to survey the bioloqical communities on and around BCAR. In April 1992, qualitative surveys of the biological communities were conducted on one of the eight modules at BCAR and at a nearby sand-only site. One of the modules, Module D, located in 90 feet of water (MLLW), was surveyed for fish, macroinvertebrates, and turf community organisms (small plants and sessile animals). Twelve species of fish were observed, including kelp bass (Paralabrax clathratus) and barred sand bass (P. nebulifer). Eight macroinvertebrate species were observed, rock scallops (Crassedoma giganteum) being the most abundant. The turf community was comprised of thirteen invertebrate taxa, among which erect ectoprocts (Bugula spp.) were the most numerous. Two species of foliose red algae (Rhodymenia pacifica and Anisocladella pacifica) were also observed. The reef has reached an advanced stage of successional development with fish and invertebrate communities diverse and well established. However, due,.to its depth and the turbidity of surrounding waters, this reef is not likely to ever support a diverse algal community. The diversity and abundance of fish and macroinvertebrates were, as to be expected, much lower in the nearby sand-only site. Only two species of fish and seven macroinvertebrate species were observed. Of these, only the sea pen, Stylatula elongata, was common. Overall, when compared to nearby sand-only habitats, Bolsa Chica Artificial Reef appears to contribute substantially to the local biological productivity. In addition, the concrete rubble used in BCAR' s construction appears to be performing as well as the quarry rock used in all of CDFG's experimental reefs. (Document pdf contains 22 pages)

    Description: Runs have dwindled in many parts of California and additional protection or management actions are needed to protect the fish from further declines. The following is a report requested by the Fish and Game Commission on the status and current management of spring-run chinook salmon stocks. Fish counts presented in this report were developed by a variety of methods. Some of them are estimates of total run-size or spawning escapement, while others are indices of abundance derived from counts of maturing fish in their holding areas. It is important to note the stock assessment method used. Index area counts will always underestimate the true run size, often by a very large margin.

    Description: Jack mackerel landings in southern California during the 1972-73 to 1983-84 seasons indicate successful year classes in 1974, 1976, 1978, and 1980, each contributing over 150 million fish to the fishery. These alternated with weak year classes in 1973, 1975, 1977, 1979, and 1981, each contributing less than 60 million fish. A majority of the fish were caught as one- and two-year-olds and were less than 300 mm in length. (45pp.)

    Description: Speckled scallops, Argopecten circularis (Sowerby, 1835), were sampled at Agua Hedionda Lagoon, Carlsbad, San Diego County from March 1984 to October 1986, to obtain basic life history data. Monthly samples of scallops were collected, measured, and released to obtain length frequency data for estimates of growth, life span, and spawning period. Subsamples of scallops were collected for determination of gonadal-somatic and adductor muscle-somatic indices. In 1984 large concentrations of speckled scallops were found on the sand-silt bottom of the lagoon, closely associated with eelgrass, Zostra marina. During the course of the study the numbers of scallops declined, until their virtual disappearance at the end of 1986. Monthly length frequency plots from 24,375 scallop measurements indicate that this is a rapidly growing species with a short life span. Gonadal- and adductor muscle-somatic indices from subsamples of 1,714 scallops indicate first spawning at age one and a relationship between temperature and spawning. Based on this study management recommendations are made for the speckled scallop. (39pp.)

    Description: On 24 June 1985 the U.S. Navy's Deep Submergence Rescue Vehicle AVALON [DSRV-2] was used to locate low-level radioactive waste containers and make observations of deepwater benthic fishes and invertebrates at the 900 m (2952 ft) radioactive waste disposal site approximat1y 4.4 km SW of the Farallon Islands off San Francisco, California. During the three hours on the bottom in depths of 975 to 1039 m (3198 to 3408 ft) five identifiable species of demersal fishes were observed: Dover sole, Microstomus pacificus; thornyheads, Sebastolobus spp.; deepsea sole, Embassichthys bathybius; sablefish, Anoplopoma fimbria; and Pacific hagfish, Eptatretus stoutii. Unidentifiable demersal fishes from the families Macrouridae and Zoarcidae were also observed. Several species of macroinvertebrates were also identified, including the tanner crab, Chionoecetes tanneri, and a large sea pen, Stylatula elongata. One low-level waste container was located. The biology of the observed fishes and their commercial importance is discussed. (22pp.)

    Description: This is the episodic variations in stream water chemistry associated with acid rainfall and run-off and the effect on aquatic ecosystems, with particular reference to fish populations in North West England produced by the North West Water Authority in 1985. This report looks at the biological, physical and chemical information collected over a five year period from over 100 sites on upland streams in the North West Region of which drained rocks of low buffering capacity. In both Lake District and South Pennine sites striking differences were found between the composition of invertebrate communities inhabiting acid-stressed and less acid-stressed streams. Electric fishing surveys showed that acidic streams (geometric mean pH 〈5.5) generally had abnormally low densities of salmonids ( 〈 0 .2m2) and that 0+ fish were very few or absent. The latter indicates recruitment failure. Salmon were more sensitive than trout to low pH.

    Description: Red abalone, Haliotis rufescens, were collected at Johnsons Lee, Santa Rosa Island, in the summers of 1978 through 1982, and in 1984, to obtain data for determining various fishery population parameters. Annual visits to the study site were made at yearly intervals to simplify growth calculations. During the first four visits, 2145 red abalones were tagged, measured, and replaced. Shell damage, soft tissue injuries, and causes of mortality were noted. The method of tagging is described. Recovery of first tagged abalone after one year was approximately 30%. Analysis of variance of the annual samples indicated that the samples were, with one exception, not different. Summaries are presented of the number of abalone collected and tagged by year, frequencies of shell damage, soft tissue injury, predatory sponge infestation, and total mortality. Appendices include a listing of the raw size data and various codes for each tagged abalone. (56pp.)

    Description: The sea otter, Enhydra 1utris, is fully protected in California by both state and federal law. Despite this protection the population has not grown appreciably since at least 1976. Research efforts directed at identifying the reasons for the lack of population growth have concentrated on sources of mortality and their contribution to total mortality. The accidental drowning of sea otters in gill and trammel nets used to take California halibut, Para1ichthys ca1ifornicus, was identified as a source of mortality which has probably increased as the sea otter population expanded into areas of intense fishing. As a result, an existing gill and trammel net fishery observation program in Monterey Bay was expanded to assess the extent and significance of the accidental drownings of sea otters in the areas near Morro Bay and Port San Luis. Three different estimates of the number of sea otters drowned annually in gill and trammel nets were generated using comparable data bases. The average of these estimates was approximately 80 sea otters per year for the level of fishing effort expended during the June 1982 through June 1984 study period. Back calculations of the annual take of sea otters by the gill and trammel net fishery for California halibut were made for each year from 1973 through 1983. These calculations suggest that the level of accidental take of sea otters during the last decade may have been high enough to be a significant factor in the lack of sea otter population growth.

    Description: This is the Acid rain project biosurveys of streams in the Wastwater catchment produced by the North West Water Authority in 1985. This report forms part of a series on component biological investigations, identified by location or topic, within the acid rain project. Reporting of the Wastwater catchment data would not have been given priority ordinarily, but it has been brought forward to coincide with J. Robinson's reporting of his investigations of land use and liming in the catchment. This report shows water chemistry results of a violent rainstorms such pH, alkalinity, Mg, Ca and Al. Moreover it shows invertebrate, fish and chemical data for Wastwater catchment sites.

    Description: This is the assessment of the flow requirements for upstream migration of salmonids in some rivers of North West England produced by the North West Water Authority in 1985. This report focuses on the automatic fish counters operating on the resistivity principle used for several years in North West England. This report aims to investigate the flow requirements for upstream migration of salmon and migratory trout. The data obtained confirmed that during summer months most fish movement occurs in the higher range of the available flows, but the migration flow range varied from year to year, depending on prevailing river levels. Of the other environmental variables measured, only water temperature and incident light intensity appear to have any direct association with fish movement. Information on migration flow ranges were used in conjunction with computer simulations of the effects of abstraction proposals on historical flows to assess the implications of these proposals for migratory fish.

    Description: Nearly 49,000 metric tons (MT) of anchovies were taken during the 1978-79 season, followed by 32,390 MT in 1979-80, 60,678 MT in 1980-81 and 45,150 MT in 1981-82. A total of 14,076 fish was sampled during the four seasons for age, length and sex. The fishery during the four seasons consisted mainly of young-of-the-year and age groups I and II fish. The 1978 and 1979 yr classes comprised the major share of the catch. Seasonal mean lengths varied from 112 mm standard length (SL) in the 1979-80 season to 122 mm SL for the 1981-82 season. Female to male sex ratios ranged from 1.17:l (1978-79 season) to 1.59:l (1979-80 season). (28pp.)
