    Description: This is the River Ehen and Tributaries SSSI consultation Protocol for the Environment Agency with English Nature, produced in 1998. The Protocol is intended to provide for consistency of approach, to clarify responsibilities and help to streamline the statutory consultation and consenting procedures in which both organisations are involved. It provides guiding principles on the approach to management issues. Based on the operations likely to damage the special interest (OLDSI) which forms part of the SSSI notification, the protocol identified acceptable management activities which contribute to the special interest of the site and those which may adversely affect that interest. OLDSI includes activities such: land drainage consents, discharge consents, herbicides approvals, fish-stocking consents, fishing licences, abstraction and impoundment licences, consents to construct/test pump boreholes, integrated pollution Control Licences and Waste Management Licences, capital projects, flood defence maintenance works, water resources, fisheries, pollution control, ecology surveys and Recreation works.

    Description: This is the history of contamination in sediments from the Mersey Estuary: Development of a chronology for the contamination of the Mersey Estuary by heavy metals and organochlorines Report produced by the Environment Agency in 1998. This report looks at the history of industrial contamination of the Mersey and Ribble Estuaries back to the early part of the last century, many decades before the start of monitoring programmes providing a remarkably detailed picture of very complex changes. There is a clear record in the sediment of the contamination by each heavy metal (including: Cu, Cr, Hg, Pb, Zn) and organochlorine chemical (including DDT isomers and PCB congeners) studied. The results of the study clearly show the increases in levels of contamination as industry expanded early last century followed by various improvements as this century progressed. Each pollutant has its own idiosyncratic pattern of change with some improvements predating modern environmental concerns whilst other changes seem to relate directly to recent improvements in legislative control. Overall, for the pollutants studied, the results clearly demonstrate the magnitude of improvement that has been achieved in what was a very polluted area. The only major reservation to this story is that despite the wide range of substances covered, many other potentially important pollutants remain to be studied in a similar manner.

    Description: This is the Mersey Estuary baseline survey: Analysis of macroinfaunal samples, literature review and database production report produced by the Environment Agency North West in 2002. This report presents an ecological review of the Mersey estuary along with an extensive bibliography of the available environmental literature for this system. The central objective of this programme has been to provide the information necessary to support the Environment Agency's review of existing and future consents (for discharges, abstractions etc) in the Mersey estuary. This review of consents was required because the Mersey had been designated as a Special Protection Area (SPA) under the EC Birds Directive. Therefore under Regulation 50 of the Conservation, the Environment Agency was responsible for reviewing any extant consent, or future applications, which may directly or indirectly, affected this SPA.

    A report on the strategic fisheries stock assessment survey of the minor catchments in South West Cumbria 1996 with particular reference to salmonids (2021)

    Description: This is the report on the strategic fisheries stock assessment survey of the minor catchments in South West Cumbria 1996 with particular reference to salmonids, produced by North West Water in 1994. The 1996 Minor Catchment survey indicates variations in salmonid production within these catchments. Survey results indicate that production may be reaching its limit in certain areas whilst others are underachieving and others are unsuitable for salmonid production. Trout production within the catchments is higher and more widespread than that of salmon. Water quality levels vary considerably between catchments and intra-annually within individual catchments. The need for selective habitat surveys, with a view to habitat improvement schemes (H.I.S) is discussed. This report formed a basis for subsequent reports, thus, allowing data comparisons and analysis of production level fluctuations. It was the most extensive assessment of these catchments to date, taking into account comparisons with the new National Database on salmonid production in England and Wales.

In 1996 the National Rivers Authority (NRA) report on the 1992 strategic stock assessment for the Upper Derwent catchment Jane Atkins recommended that should subsequent electrofishing show continued low densities, a survey of the invertebrate fauna should be undertaken to assess the food availability for salmonids, in order that lack of food could be ruled out as a contributory factor in their poor breeding success. Additionally the survey looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Description: This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the South Pennine Moors cSAC/SPA.The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the Rixton Clay Pits cSAC of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the Rixton Clay Pits cSAC of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

    Description: This is the Water Quality Monitoring in the Mersey Estuary report produced by the Environment Agency in 2001. This report focuses on the Water Quality Monitoring Programme held in the Mersey Estuary. Since the mid-1960s water samples have been collected at approximately monthly intervals along the length of the estuary between Warrington and New Brighton and in later years further off-shore. This data-set provides an invaluable resource to determine how the very large capital spending of recent years has resulted in the dramatic improvements in water quality that we are now able to record. Initially, the interest was focused on parameters such as dissolved oxygen, BOD, nutrients and suspended solids. Over the last decades, as analytical methods have improved, toxic metals and persistent organic compounds have been included in the routine monitoring programme at a limited number of sites. Moreover, with the introduction of the European Water Framework Directive monitoring programmes it was an opportune time to review the Mersey monitoring strategy. This revised monitoring programme required data from several other components (water, sediments, flora, fauna, fish and birds. This report also contains information about Routine monthly surveys, Special surveys, Chloralkali Directive, UKNMP, British Geological Survey, EDMAR and NERC Environmental Diagnostics Thematic Programme.

    Description: This is the report on the strategic fisheries stock assessment survey of the River Winster 1995 together with a coarse fish survey in 1994 and reference to the 1995 drought, produced by the Environment Agency North West in 1996. Salmonid production within the Winster catchment was dominated by trout although good densities of salmon juveniles were found on some main river sites. Despite suffering drought conditions for much of 1995, only salmon fry production appeared to have been affected. Coarse fish populations once found in the lower reaches of the Winster appear to have declined to very low levels with no fish sampled. This may be partly due to broken tidal gates allowing saline intrusion. It seems that the lower river was suited to the development of a recreational coarse fishery, now that the gates have been repaired. This report completes the strategic stock assessment surveys planned for the period 1992-1995. It represents the last major catchment that was surveyed to determine the current status of fisheries in the South and South West Cumbria areas.

    Description: This is the report on the Leven estuary project: Fisheries Department final report produced by the Environment Agency North West in 1997. This report contains information about Leven estuary, river Leven catchment, river Crake catchment and the Ulverston Discharges. The Leven estuary is characterised by being very shallow, and shares the extremely variable tides and currents that characterize the whole of Morecambe Bay. There was little detailed knowledge of the impact on the Leven estuary, and particularly its fisheries, of the discharges from Ulverston. There has been some concern expressed by the lave netsmen and the general public about the possible harmful effects of the effluents on the biology of the estuary. In the absence of a definite strategy for the protection and management of the estuary was born this project. The project involves water quality monitoring, effluent and estuary toxicity testing, tracking of effluent plumes, and salmonid tagging and tracking. The entire project commenced in June 1995 and was expected to reach a conclusion in March 1997. The information gained from the project was expected to contribute to the creation of a 'mixing zone' for the effluent, and to improve the environmental management of the estuary and protection of its fishery.

    Description: This is the Brown trout habitat assessment on the River Bela catchment produced by the Environment Agency North West in 1997. The Environment Agency (EA) and its predecessor the National Rivers Authority undertook strategic fish stock assessments in 1992 and 1995 on the River Bela catchment. These surveys found low numbers of brown trout {Salmo trutta) at some sites. Following this, habitat evaluation assessments were undertaken on the eleven poorest sites Factors probably responsible for declining trout populations on the three main tributaries of the Bela catchment include: Overgrazing by farm stock; Lack of suitable cover for parr; the absence of suitable spawning areas; existing potential of certain areas within the catchment not being utilised, due to poor dispersal. Habitat Improvement Schemes (H.I.S) are discussed and prioritised.

    Description: This is the report on the River Ehen salmonid fishery - current status and a summary of fisheries work during the period 1993-1996, produced by the Environment Agency North West in 1997. This report draws together a number of investigations and surveys undertaken following the 1993 Strategic fisheries survey of the River Ehen. It specifically details the historic catch data available for this catchment for both salmon and sea trout and examines the current stock levels based on this data. Concerns over sea trout stock levels are raised and a detailed examination of the possible limiting factors involved is included. Information from surveys on the River Keekle is analysed with reference to its potential for sea trout production both currently and with the proposed clean up on Oatlands tip. Salmon production in the historically acidified River Liza sub catchment is examined along with ways of boosting production further following recent reductions in acidic episodes. Future and current issues and actions required in the catchment are listed along with the responsible party and estimated costs involved.

    Description: This is the Cheshire stillwaters summary results 1999 from the Environment Agency North West. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. During 1999, stillwaters monitored for the third year of the Stillwaters Monitoring Programme were Tabley Mere, Comber Mere and Norbury Mere. Surveys of Petty Pool and Betley Mere continued for a second and third year respectively after water quality concerns were highlighted in previous end-of-year reports. Oak Mere was also surveyed for the third year running due to its unusual ecology. This year, the variety of parameters monitored was limited to algal, zooplankton and water chemical samples. Fisheries and marginal invertebrate surveys were not completed due to lack of resources.

    Description: This is the Stillwaters monitoring programme. Summary results 2001 and 2002 from the Environment Agency North West. Until January 2001 the South Area Stillwaters Sampling Programme consisted of a rolling programme where five to six stillwaters were sampled three times a year (spring, summer and autumn). However, this method was not yielding the water quality information required for long term monitoring. Local weather conditions influence short-term water quality events, e.g. algal blooms, nutrient consumption, stratification, super-saturation etc, so results from one day sampling could only be regarded as individual ‘spot’ samples. Therefore year-on-year comparisons could not be made. It was decided that long-term water quality monitoring of the stillwaters would benefit more from sampling nutrient abundance over winter months. This would give an insight into the carry-over of nutrients available for algal growth the following year and so year-on-year productivity could be assessed. Survey results shown in this report were from: The Mere, Rostherne Mere, Melchett Mere, Tabley Mere, Tatton Mere, Hatchmere, Oak Mere, Black Lake, Chapel Mere, Bar Mere, Oss Mere, Marbury Big Mere, Comber Mere and Betley Mere.

    Description: Redd counting is an integral part of most Fishery Officers duties. The number and distribution of salmonid redds throughout salmonid catchments provides invaluable information on the range and extent of spawning by both salmon and sea trout. A project was initiated by the Fisheries Science and Management Team of Central Area, North West Region in England in liaison with the Flood Defence function. The main objective of this project was to assess redd count data for Central Area and attempt to quantify these data in order to produce a grading system that would highlight key salmonid spawning areas. By showing which were the main areas for salmon and sea trout spawning, better informed decisions could be made on whether or not in-stream Flood Defence works should be given the go-ahead. The main salmonid catchments in Central Area were broken into individual reaches, approximately 1 km in length. The number of redds in these individual reaches were then calculated and a density per lkm value was obtained for each reach. A grading system was devised which involved looking at the range of density per km values and dividing this by five to produce 5 classes, A - E. A sixth class (F) was used where the density per Ion value was 0.00. This grading system was calculated at two levels of detail. Grades for salmon and sea trout were produced for each individual catchment and also on an Area-wide level. Maps were produced using a range of colours to represent the grade for each reach. These maps provide a highly useful overview of the status of salmonid spawning for each catchment over individual years and highlight the key salmon and sea trout spawning areas in each catchment. These maps and the associated summary data should now provide Flood Defence and Fisheries staff with a fairly detailed overview of the status of spawning in any location within the. main salmonid catchments in Central Area. Although these maps are very useful they should only be used as a guide. The current practice of consulting with the local Fishery Officer should be continued to ensure that expert local knowledge is taken into account.

    Description: This report summarises the findings of a series of electric-fishing surveys carried out at four sites on the River Ribble from September 1997 to September 1998. The aims of these surveys were to assess the impact on juvenile salmonids of a pollution incident involving Synthetic Pyrethrin (SP) that occurred near High Birkwith I (SD 802 767) in September 1997.One of these sites was 2.65km upstream of the pollution whilst the remaining three were at varying distances downstream. Data was collected during surveys of the River Ribble in 1992, 97 and 98. The 1997 and 1998 surveys were carried out specifically to monitor for any possible effects of the SP discharge.Data are shown as grades derived from the National Fisheries Classification scheme (NFC). Results are given for the four salmonid life stages; 0+ trout, 〉0+ trout, 0+ salmon, 〉0+ salmon and also Total Salmonids.

    Description: This is the Cheshire stillwaters. Summary results of September 1998 from the Environment Agency, 1998. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. Oak Mere, Tatton Park Mere and Hatch Mere were surveyed between the 29th - 30th September as part of the three year rolling programme. Betley Mere, Petty Pool, Scotman's Flash and Pearson's Flash were also surveyed. Surveys also included algal and zooplankton samples, which are to be analysed by APEM and presented in the end of year report. The section on results contains information about water column profile; and nutrients (chlorophyll a; Phaeophytin; Nitrate and Nitrite; Ammonia; ortho-Phosphate; Silicate; and total Phosphorus).

This allows assessment of nutrient ‘carry-over’ available for algal growth in the following year, plus year-on-year productivity. 14 stillwaters are monitored each year. The environmental issues associated with each Stillwater are summarised in the table below. Bank-side water samples are taken for nutrients (N, P and S) and chlorophyll. A YSI multi-parameter sonde measures temperature, pH, specific conductivity and dissolved oxygen (% saturation). Survey results shown in this report came from: Oak Mere and Bar mere.

    Pelagic shark/swordfish drift gill net fishery: management information document (2021)

    Description: In 1977 a new fishery began to develop off the coast ofsouthern California. Long gill nets, drifted near the surface in the deep offshore waters, were being used successfully in landing pelagic sharks, primarily threshers. Recent increases in the retail demand for fish had led wholesale buyers to look for new sources of fish protein. Shark meat looked promising to many buyers. Aided by the public's rekindled fascination for sharks, the timing seemed favorable for introducing sharks as food. Word spread that wholesalers were willing to pay a good price for sharks. This created what appeared to many commercial fishermen to be the beginning of a bonanza.The new shark fishery grew rapidly. The number of vesselsengaged in offshore drift gill net operations grew from about 15 in 1977 to approximately 230 by 1984.Fishery biologists have expressed concern over the rapidexpansion of the commercial shark fleet. Historically, sharkfisheries have tended to decline after their initial success, due principally to slow growth and reproductive rates which seem to characterize sharks as a group. Perhaps the new thresher shark fishery might also be subject to a similar decline.Biologists were not the only ones who looked on the newindustry with concern. Among sport fishermen and conservation groups, rumors of marlin, whales, and seals taken by the hundreds became commonplace.Concern spread among the traditional swordfish harpoonfleet that landings by drift gill nets might glut the swordfish markets, driving prices down to the point that harpooners could no longer compete. Some harpooners voiced fears that drift gill nets might even overfish the swordfish stocks, causing serious declines in the availability of fish.Some conservation groups sought to ban the use of all gillnets, feeling that gill nets are inherently indiscriminant in what they catch and that the benefits derived from their use is always over-shadowed by the waste of marine life resulting from their use.In September of 1980, the Legislature enacted Assembly Bill2564 (Kapiloff), which directed the Department of Fish and Game to conduct a study of the drift gill net shark fishery. The purpose of the study was to determine what impact the use of drift gill nets might have on existing fisheries or upon other members of the local marine community such as whales, dolphins, and seals. The final report of that study "Pelagic Shark/Swordfish Drift Gill Net Fishery Management Information Document" was sent to the California Legislature in January 1983.In September 1982, the Legislature enacted Senate Bill 1573(Beverly), directing the Department of Fish and Game to continue monitoring the drift gill net fishery. It also directed, that a further study be conducted on the status of the thresher shark and swordfish resources off California and on the effects of the fishery on other resources. A report on this study would be prepared and delivered to the Legislature on or before January 1, 1985. The study was conducted. This is the report on that work. (77pp.)

    Description: The spawning biomass of Pacific herring in San FranciscoBay and Tomales Bay was estimated to be 65,441 tons and 5,583tons, respectively during the 1980-81 season. This is thehighest estimate to date for San Francisco and continuesa rising trend in abundance. The Tomales Bay population hasfluctuated around an annual mean of 6,000 tons since 1973. (24pp.)

    Description: The catch landed and effort expended by private-boat sportfishermen were studied in southern California betweenJanuary and March 1982, to determine the impact ofone segment of the sport fishery on local marine resources.Fishermen returning from fishing trips were interviewed atlaunch ramps, hoists, and boat-rental facilities. This report contains quantitative data and statistical estimates of total effort, total catch, catch of preferred species, and length frequencies for those species whose catches are regulated by minimum size limits.An estimated 155,000 organisms were landed by 52,000 anglersand 2,400 divers. The two major components of the catch werewhite croaker, Genyonemus lineatus, 44,000 landed and Pacific mackerel, Scomber japonicus, 23,000 landed. Together these two species made up over a third of the estimated southern California sport catch.Angler compliance with size limit regulations was generallyfavorable. Ninety-one percent of all basses, Paralabrax spp., examined were of legal size, as were 73% of the California halibut, Paralichthys californicus. A 24-inch (fork length) size limit was imposed upon Pacific bonito, Sarda chiliensis, as of March 1, 1982; none of the 399 bonito measured in March were of legal size. (31pp.)

    Description: Hydroacoustic monitoring and sampling of San Francisco Bayherring stocks were conducted from December 1981 to March 1982. Major schools usually were located in central San Francisco Bay between 30 and 90 ft deep prior to spawning. The largest school observed had an estimated volume of 1.5 billion ft3. There was some consistency between the maximum calculated volume of a school prior to spawning and the subsequent spawning biomass estimate, based on egg counts, by Marine Resources Region personnel.Herring samples were obtained with variable mesh gill nets, a midwater trawl and from commercial purse seine and lampara vessels. Eight discrete spawns were sampled for size and age composition, although data from December and early January samples were biased due to selectivity of the gill net mesh array. In general, a trend was observed of decreasing mean size and age as the season progressed.Ages of herring ranged from 2 to 9 years. From 87 to 94% of the fish sampled with a midwater trawl, 1.5- to 2.5-in mesh array gill net, and from commercial roundhaul samples consisted of 2-, 3-, and 4-year-olds.Calculation of desired sample size for future work indicatesthat 17 fish per 10-mm size interval need to be aged to determine age composition of each spawning population.

    Description: State law provides for the initiation of a fishery for Pacific sardines, Sardinops sagax caeruleus, when the spawning biomass of sardines reaches 20,000 short tons. Data from ichthyoplankton surveys, sea survey cruises, the mackerel fishery sampling program, and the live-bait fishery monitoring program are discussed with regard to an increase in population size. It appears that the spawning biomass of the northern stock of Pacific sardines remains below 20,000 tons. Legislation passed in 1983 which affects the incidental take and commercial use of sardines is also discussed. (9pp.)

    Description: In Tomales Bay, 5-, 6-, and 7-yr-old herring, Clupea harengus pallasi, composed 75% by number of the 1984-85 season's catch. In San Francisco Bay, 2-, 3-, and 4-yr-old herring composed 82% by number of the roundhaul catch, and 5-, 6-, and 7-yr-old herring composed 68% by number ofthe gill net catch.The percent of 4-yr-old herring increased to a record high level in the San Francisco Bay gill net catch.Recruitment of 2-yr-old herring into the San Francisco Bay roundhaul fishery was excellent, with 2-yr-old herring composing 41% of the catch.The growth rate of herring improved in both Tomales and San Francisco Bays, after the period of poor growth during the recent El Nino, when the weight of herring averaged 20% below normal.(23pp.)

    Description: Herring schools were surveyed hydroacoustically and sampled in San Francisco Bay from late October 1986 to March 1987. Eight large schools (greater than 1000 tons each) spawned from December to February and seven smaller schools were detected throughout the spawning season. Total acoustic biomass estimate using a "visual integration" technique was 40,930 tons, and it was determined from spawn escapement and commercial landings that an additional 2240 tons were not detected. This is a slight increase from last season's total of approximately 42,200 tons. For the first time, biomass was also estimated using echo integration equipment. A total biomass was obtained of 33,050 tons, including herring not detected acoustically. This estimate must be considered preliminary and subject to revision after target strength of San Francisco Bay herring is determined.Eighty-seven samples, containing a total of 13,125 herring, were collected with variable-mesh gill net and midwater trawl or obtained from the roundhaul and gill net fisheries. Mean body length (BL) of sampled herring decreased by about 20 mm from the beginning to the end of the spawning season. A combination of variable-mesh gill net and midwater trawl samples for a particular school closely approximates mean BL and age composition data from unbiased roundhaul samples.Age-weight and age-length relationships were average to above average compared with those of the previous two seasons. The 1982 year class exhibited unusually good growth, with a mean BL of 202.8 mm for herring aged from stratified random samples.The 1982 through 1985 year classes (5- through 2-yr olds)contributed 97% by number and 95% by weight to the total 1986-87 spawning biomass in San Francisco Bay. Good recruitment has occurred during the past four seasons. The weak 1981 year class contributed little to the total biomass as 6-yr olds.Average catch per tow of young-of-the-year (YOY) herring is a potential index of abundance for recruitment 18 months later as 2-yr olds. Estimated recruitment has only varied by 15% during the past three seasons and does not reflect the magnitude or trend in YOY catches in the bay. (85pp.)

    Description: The catch landed and effort expended by private-boat sportfishermen were studied in southern California marine watersbetween October and December 1982, to determine the impact of one segment of the sport fishery on local marine resources. Fishermen returning from fishing trips were interviewed at launch ramps, hoists, and boat-rental facilities. This report contains quantitative data and statistical estimates of total effort, total catch, catch of preferred species, and length frequencies for those species whose catches are regulated by minimum size limits.An estimated 157,000 organisms were landed by 57,700 anglers and 4800 divers. The major components of the angler catch were Pacific mackerel, Scomber japonicus (28,700 estimated catch): white croaker, Genyonemus lineatus (24,000 estimated catch); and Pacific bonito, Sarda chiliensis (16,700 estimated catch). These three species represented almost half the total estimated angler catch. Rockfishes, Sebastes spp: were a major catch component; the 35 rockfish species landed made up 24% of the estimated catch. Divers landed an estimated 14,700 fishes and invertebrates. Chief among these were abalone, Haliotis spp. (4200 estimated catch);rock scallop, Hinnites rugosus (3600 estimated catch); andCalifornia spiny lobster, Panulirus interruptus (2500 estimated catch).Angler and diver compliance with size-limit regulations wasgenerally favorable, with diver compliance being particularly scrupulous, especially with invertebrate species. The compliance rate for California halibut, Paralichthys californicus, showed a drop from the previous quarter (July - September 1982) from 70 to 59% legal. During the same time period, size-limit compliance rose from 4 to 20% for Pacific bonito, a species with a tolerance allowing the take of some under-sized fish. (28p.)

    Description: The catch landed and effort expended by private-boat sport fishermen were studied in southern California between January and March 1983 in order to determine the impact on local marine resources by one segment of the sport fishery. Fishermen returning from fishing trips were interviewed at launch ramps, hoists, and boat-rental facilities. Thisreport contains quantitative data and statistical estimates of total effort, total catch, catch of selected species, and length frequencies for those species with minimum size limits.An estimated 74,200 organisms were landed by 29,400 anglers and 1500 divers. The major species in the angler catch included white croaker, Genyonemus lineatus, (16,000 landed) and Pacific mackerel, Scomber japonicus (14,000 landed). The two species combined made up 44% of the total estimated angler catch. Divers, hampered in their activity by stormy conditions, landed an estimated 1700 rock scallop, Hinnitesmultirugosus. This single species represented almost a third of the estimated diver catch.The length frequency data, collected for size-regulated fish and shellfish species, show that minimum size-limit compliance was very good for both angler-caught and diver-caught species during the reporting period.

Approximately 91% of all basses, Paralabraxspp., measured were legal size. Only 10% of the whiteseabass, Stractoscion nobilis, were larger than the minimumsize limit imposed on March 1, 1982. Divers' compliancewith size limit regulations on abalone, averaged 94%. (33pp.)

    Description: The age and size composition of the 1980-81 and 1981-82herring catch in Tomales and San Francisco Bays have remained relatively stable over the past two seasons. TheTomales Bay gill net catch was dominated by 5-, 6-, and 7-yr-old herring which combined for an average of 76% ofthe catch each season. The San Francisco Bay gill netcatch was dominated by 5- and 6-yr-old herring whichcombined for an average of 62% of the catch over the pasttwo seasons. The average size of herring in the gill netcatch declined in San Francisco Bay due to smaller meshnets employed by fishermen late in the season when largeherring are less abundant. (18pp.)
