    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: 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: 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: In Tomales Bay, 4-, 5-, and 6-yr-old herring, Clupea harengus pallasi, composed 85% by number of the 1986-87 season's catch. In San Francisco Bay, 2-, 3-, and 4-yr-old herring composed 88% of the roundhaul catch, and 4-, 5-, and 6-yr-old herring composed 86% by number of the gill net catch.The age composition of both the Tomales Bay and San Francisco Bay gill net catch has shifted to primarily 4-, 5-, and 6-yr-old herring.Recruitment of 2-yr-old herring into the San Francisco Bay roundhaul fishery was good, with the 1985 yr class composing 37% of the catch.The mean length of herring in the San Francisco Bay roundhaul catch decreased to 174 mm BL, and the mean length of the gill net catch decreased to 194 mm BL. The mean length of the Tomales Bay catch also decreased to197 mm BL.Average weight at age of Tomales Bay herring is below average for the fourth consecutive year. In San Francisco Bay the average weight at age is above average, even though length at age declined slightly. (20pp.)

    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.)

    Description: Shark angling derbies have been held in Elkhorn Slough since 1946, and archery derbies since about 1973. Elkhorn Slough is an important pupping and breeding area for leopard sharks, Triakis semifasciata, and bat rays, Myliobatis californica, and a spawning or nursery area for many other species of fish. With the establishment of the Monterey BayNational Marine Sanctuary, these derbies, especially the archery derby, have become somewhat controversial.Leopard sharks pup in late spring to early summer, peaking in June.Bat ray pupping peaks in July. Both species breed shortly after pupping.Since 1988, most sharks and rays caught in the angling derbies have been tagged and released under a program developed by Moss Landing Marine Laboratories. No tags have been recovered, suggesting a large population in the area. Prior to the tagging program most sharks and rays taken in the angling derby were rendered at the local tallow works.All sharks and rays that are taken in the archery derby are killed, but relatively few sharks and rays are taken by archers. In 1993,43 sharks and rays were kept by anglers and 13 by archers.The commercial catch of leopard sharks in California averaged 43,000 pounds from 1990 to 1992, and the estimated sport catch of leopard sharks is about 270,000 pounds annually. In comparison, the take during Elkhorn Slough shark derbies is not significant and is not considereda threat to the resource. However, the moral or ethical issue of conducting shark derbies in a marine sanctuary remains. (7pp.)

    Description: The jack mackerel, Trachurus symmetricus, resource off thewest coast of North America is known to be large and widelydistributed. The spawning biomass is estimated to be 2.1 to 4.8 million tons based upon abundance of jack mackerel eggs collected at sea. The distribution extends from the Gulf of Alaska to the Gulf of Tehuantepec, off the coast of southern Mexico, and as far as 1,500 miles seaward. Within this range lies an area of maximum density which extends from Point Conception to central Baja California.Jack mackerel biological data has not been processed veryrapidly due to higher priorities for analysis of sardine andPacific mackerel data, and the apparent healthy condition ofthis resource. The California Department of Fish and Gameinitiated several projects in 1972 to resolve unanswered biological questions. (14pp.)

    Description: The California yellowtail, Seriola dorsalis, is a highlyfavored sport fish and a minor commercial species. Since1954 commercial landings have been limited by demand, and thesport catch has been about three times the number of fishcaught by commercial fishermen.Recreational fishing for yellowtail in southernCalifornia waters is almost entirely dependent on annualmigrants from central and northern Baja California. The resource is presently healthy but reduced catches off California could be the result of an expanded catch off Mexico. (19pp.)

    Description: The catch per unit of effort of the sardine along thecoast of California has been published for the period 1932 to 1953. This paper continues the catch per unit of effort study through the 1961-62 season. Although the catch per unit of effort varied greatly during this later period, it never reached the high levels reported during the 1940's or decreased below the values reported for the disastrous seasons of 1952-53 and 1953-54. Mortalities and year class strengths are briefly discussed. (45pp.)

    Description: The sea otter, Enhydra 1utris, is fully protected inCalifornia by both state and federal law. Despite thisprotection the population has not grown appreciably since atleast 1976. Research efforts directed at identifying thereasons for the lack of population growth have concentratedon sources of mortality and their contribution to totalmortality.The accidental drowning of sea otters in gill and trammelnets used to take California halibut, Para1ichthysca1ifornicus, was identified as a source of mortality whichhas probably increased as the sea otter population expandedinto areas of intense fishing. As a result, an existinggill and trammel net fishery observation program in MontereyBay was expanded to assess the extent and significance ofthe accidental drownings of sea otters in the areas nearMorro Bay and Port San Luis.Three different estimates of the number of sea ottersdrowned annually in gill and trammel nets were generatedusing comparable data bases. The average of these estimateswas approximately 80 sea otters per year for the level offishing effort expended during the June 1982 through June1984 study period.Back calculations of the annual take of sea otters by thegill and trammel net fishery for California halibut weremade for each year from 1973 through 1983. Thesecalculations suggest that the level of accidental take ofsea otters during the last decade may have been high enoughto be a significant factor in the lack of sea otterpopulation growth. (31pp.)

    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.

    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.)

    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 isdescribed.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 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, SantaCruz, Santa Rosa, and San Miguel Islands) and waters within1 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 theChannel 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.(PDF contains 24 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.(PDF contains 24 pages.)

    Description: In Tomales Bay, 4-, 5-, and 6-yr-old herring, Clupea harengus pallasi, comprised 83% by number of the 1988-89 season's gill net catch.Recruitment of the 1985 year class (4-yr-olds) was relatively good, comprising 22% of the gill net catch by number.Average length of the Tomales Bay gill net catch decreased to 197 mm BL because the percent of 3- and 4-yr-olds in the catch doubled over the 1987-88 season.Average weight of 4- through 8-yr-olds returned to normal this season, reversing a downward trend.The origin of the Tomales Bay catch this season changed to Bodega Bay, and the possibility that the catch may be from a different stock must be considered.In San Francisco Bay, 4-, 5-, and 6-yr-old herring comprised 81% by number of the gill net catch; average length of the catch stabilized at 195 mm BL.A subtle gear change this season is believed to have resulted in very little change in the San Francisco Bay catch characteristics. A lighter monofilament that stretches easily was used in gill nets this season. This type gear effectively lowered the mesh size of many gill nets to 2 in. These gill nets technically were legal (2 1/8 in.) whenmeasured because they stretched easily. (18pp.)

    Description: The Tomales-Bodega Bay catch during the past two seasonshas been from the northern part of outer Bodega Bay, dueto the closure of the Tomales Bay fishery.In the Tomales-Bodega Bay area, 4-, 5-, and 6-yr-oldherring, Clupea pallasi, comprised 84% by number of the1991-92 season's gill net catch.The number of 4-yr-olds increased to 26% of the gill netcatch, the second consecutive year that the percentage of 4yr-olds has increased. Four-yr-olds are completely recruited into the gill net fishery, and thus are a good indicator of relative year class strength.Average length of herring in the Tomales-Bodega Bay areagill net catch decreased due to a shift to younger herringin the catch.Herring age and size data obtained from Tomales Bay with avariable-mesh research gill net were similar to data fromSan Francisco Bay obtained with the same net. Herring over7-yrs-old were absent from the Tomales Bay variable-meshgill net and the outer Bodega Bay commercial gill net samples.In San Francisco Bay, the age composition of the gill netcatch was again 4-, 5-, and 6-yr-old herring, whichcomprised 87% of the catch. In the round haul fishery, 3and4-yr-old herring dominated, comprising 63% of the catch.Recruitment of 2-yr-old herring was poor.The average length of herring in the San Francisco Bay gillnet catch was the lowest on record, 189 mm body length (BL).The average length of herring in the round haul catchincreased to 179 mmBl due to poor recruitment of youngherring.

    Description: The spawning biomass of Pacific herring, Clupea harenguspallasi, in San Francisco Bay and Tomales Bay was estimatedto be 59,000 tons and 11,200 tons, respectively during the1982-83 season. This represents a 40% decline in SanFrancisco Bay and a 50% increase in Tomales Bay populations.Unusually high ocean temperatures and record rainfall inCalifornia are believed to have affected the distributionand/or survival of herring and caused changes in spawning habits.

    Description: The Tomales Bay gill net fishery was dominated by 5-, 6-, and 7-yr-old herring, Clupea harengus pallasi, which combined for 82% of the catch in the 1982-83 season. The San Francisco Bay gill net fishery was dominated by 5- and 6-yr-old herring, which combined for 64% of the catch. The San Francisco Bay roundhaul fishery was dominated by 3-, 4-,and 5-yr-old herring that combined for 72% of the catch. Two-year-olds composed only 14% of the catch in San Francisco Bay, indicating poor recruitment of the 1981 yr class. The mean length of herring in the Tomales Bay catch declined to 208 mm BL, but the mean length of the San Francisco Bay gill net and roundhaul fisheries increasedto 203 mm BL and 183 mm BL, respectively.

    Description: The spawning biomass of Pacific herring, Clupeapallasi, estimated from spawning-ground surveys inSan Francisco Bay declined to 41,000 tons this season.This was the second consecutive year that the SanFrancisco Bay herring population estimate has declined.In Tomales Bay, the 1991-92 season spawning biomassestimate, including the catch of 24 tons from Bodega Bay,was 1,238 tons. This was the third consecutive seasonthat the Tomales-Bodega area herring population hasincreased.The 1991-92 Humboldt Bay herring spawning biomass estimateof 225 tons, was nearly half of last season's estimate of400 tons.December and January were the peak months of spawningactivity in all areas surveyed.In San Francisco Bay, the first major spawn since the 1981-82 season occurred in the Sausalito area, and the Oakland-Alameda area accounted for 50% of all spawning activity.A total of 3.5 million m2 of eelgrass, Zostera marina,was measured in Tomales Bay this season. The eelgrassdensity declined in most beds this season. (46p.)

    Description: There were approximately 20 vessels active in the 1992 Monterey Bay squid fishery. The size of the fleet has not changed since the early 1970's when 15 to 20 vessels participated in the fishery.Since 1977, eleven steel hulled vessels have been addedto the fleet, replacing smaller wooden hulled vessels that were in use during the 1960's. The hold capacity of the new fleet remains about 800 tons, because the new larger vessels replaced small vessels that used lighters (20 - 25 ton capacity non-motorized barges).Purse seines were legalized in 1989 and have replacedlamparas which were in use during the 1960'S and 1970's.Seines used in the squid fishery are small and shallow,ranging from 120 to 200 fm in length with most lessthan 25 fm deep.Crew size has been reduced nearly 50% by the addition of net reels, power blocks, submersible fish pumps, and vacuum pumps used for unloading at dockside.In the 1970's flasher type fathometers were used by the fleet and few vessels had navigational aids. Today mostof the fleet have sonar, radar, and loran C. Three vessels carry global positioning systems.In 1988 squid attracting lights were legalized and theentire fleet used lights during the 1992 season. (21pp.)

    Description: During the Quarter we surveyed seven permanent and 48 random subtidal stations. In addition a new study was undertaken with the surveying of one random subtidal station in Diablo Cove where counts were made of small invertebrates within four 1/4-m quadrats. Red abalone, Haliotis rufescens, numbers continued to decrease at random as well as permanent stations in Diablo Cove. Bull kelp, Nereocystis lustkeana, more than doubled in density in Diablo Cove. Permanent stations showed a decline in giant red sea urchin, Strongylocentrotus franciscanus, numbers while random stations indicated an increase in abundance. (14pp.)The commercial sea urchin fishery was inactive. Commercial abalone fishermen were observed infrequently in the Pecho Rock area.

    Description: Cluster analysis was evaluated as a classification technique to group fishing locations based onsimilarities 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 inthe 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. Thedifferences 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: The Tomales-Bodega Bay catch this season was from northernBodega Bay, and the possibility that this season's catchmay be from a different stock must be considered.In the Tomales-Bodega Bay area, 5- through 8-yr-old herring, Clupea pallasi, comprised 89% by number of the 1989-90 season's gill net catch.Recruitment of the 1986 year class (4-yr olds) was relatively poor, comprising only 9% of the gill net catch by number.Average length of the Tomales-Bodega Bay area gill netcatch increased to 204 mm BL because the number of 3- and4-yr olds in the catch decreased to 11%, the lowest levelsince the 1982-83 season.The average weight at age of 4-through 8-yr-old herring didnot change significantly this season.In San Francisco Bay, for the first time since the 1982-83season, 5-, 6-, and 7-yr-old herring were the dominant agegroups comprising 79% by number of the gill net catch. Thisreverses a trend toward younger and smaller herring in thegill net catch.The average length of herring in the San Francisco Bay gillnet catch increased to 196 mm BL.The change in the size and age composition is attributed tobetter enforcement of the 2 1/8 in. gill net mesh regulation.The sex ratio of the gill net catch also improved.Females comprised 53% of the catch in both San Francisco and Tomales bays.

    Description: Field work during the quarter included surveys of permanentand random subtidal and intertidal stations. At permanentsubtidal stations densities of the brown algae Laminaria and Nereocystis decreased as did densities of giant red sea urchins, Strongylocentrotus franciscanus.Counts of small invertebrates within one-quarter meter square (1/4-m2) quadrats at random subtidal stations were begun. A total of 32 quadrats was completed. Balanophyllia elegans was the most abundant and most common animal encountered. The annual surface count of bull kelp (Nereocystis) was not possible because of the increased density; instead we utilized subtidal counts toestimate the surface canopy. An estimate of 33,000 plants was made for this year's canopy; this compares with a count of 18,000 plants last year. Sampling of random intertidal stations for the Davidson period began; 15 stations were surveyed. In addition, permanent intertidal stations 1, 2 and 3 were surveyed for abalone densities.The sea otter, Enhydra lutris, herd continued to occupy the area around Point Buchon.In November daily observations were initiated on foam location and abundance in Diablo Cove.

    Description: The 1989-90 spawning biomass estimate of Pacific herring,Clupea pallasi, from spawning-ground surveys in SanFrancisco Bay was 71,000 tons, a 5,000 ton increase over the 1988-89 biomass estimate of 66,000 tons. The San Francisco Bay herring biomass has been on an upward cycle since 1984, and results from spawning-ground surveys indicated that the population was at its highest level in eight years.In Tomales Bay the 1989-90 herring spawning biomass estimate was 345 tons. This was the third consecutive poor season. Herring have nearly abandoned Tomales Bay, and reduced freshwater in flows due to the current drought condition in California were the probable cause for the change in spawning behavior.An additional 445 tons were found in Bodega Bay byhydroacoustic surveys. The total herring biomass estimatefor Tomales-Bodega area was 790 tons.January was the month of peak spawning activity in SanFrancisco Bay, with 30,000 tons of herring spawning duringthe month. In Tomales there was only one spawning run; itoccurred on January 31, 1990.In San Francisco Bay, 67% of all spawning occurred along the San Francisco waterfront, and only 6% of all spawningactivity was in the northern part of the bay. No spawningwas found near Tiburon, Belvedere, Richmond, Berkeley,Candlestick Point, Sierra Point, Oyster Point, or CoyotePoint.A total of 3.5 million m2 of eelgrass, Zoster marina, wasmeasured in Tomales Bay this season, a decline of about10% over the past two seasons.Eelgrass density kg/m2 did not change significantly thisseason.

    Description: The spawning biomass of Pacific herring, Clupea pallasi,estimated from spawning-ground surveys in San Francisco Baydeclined to 45,850 tons this season, following a peak of71,000 tons in the 1989-90 season. This is the first majordecline since the 1983-84 El Nino.In Tomales Bay the 1990-91 spawning biomass more thandoubled to 779 tons. The spawning biomass has increasedthe past two seasons, while the fishery has been closed.There was no biomass estimate for Bodega Bay, but anadditional 95 tons of herring were caught in Bodega Baythis season. The total herring biomass for the Tomales-Bodega area is a minimum of 874 tons.Humboldt Bay was surveyed by the Department for the firsttime this season, and spawning biomass was estimated to be400 tons.January was the month of peak spawning activity in allspawning areas surveyed.In San Francisco Bay, 62% of all spawning occurred alonqthe San Francisco waterfront; for the first time therewas no significant spawninq in the northern part of the bay. Nearly 70% of the spawning activity in San Francisco Bay occurred on January 3-6, 1991.A total of 3.5 million m2 of eelgrass, Zostera marina,was measured in Tomales Bay this season. The change ineelgrass density this season varied from bed to bed, however the overall density of eelgrass in Tomales Bay declined. (44pp.)

    Description: In 1992 fishery technicians sampled 230 commercial passenger fishing vessel (CPFV) trips targeting rockfish and lingcod from the port areas of Fort Bragg, Bodega Bay, San Francisco, Monterey, and Morro Bay. The skippers of 44 vessels, and 2,190 anglers, cooperated in the study. Species composition by port area and month, catch-per-unit-effort, mean length, and length frequency of lingcod and the 18 most frequently observed rockfish species are presented, as well as fishing effort relative to time, depth, and distance from port. Total catch estimates based on unadjusted and adjusted logbook records are summarized.Average catch of kept fish per angler day was 12.6 and average catch of kept fish per angler hour was 4.0. A continuing trend of an increasing frequency of trips to deep (〉 40 fm) locations was observed in the Bodega Bay, San Francisco, and Monterey areas. Bodega Bay and San Francisco showed the highest frequency of trips to distant locations.Sixty species comprised of 29,731 fish were observed caught during the study. Rockfish comprised 93.5% by number of the total observed catch. The five most frequently observedspecies were blue, yellowtail, widow and rosy rockfishes, and bocaccio, with lingcod ranking eighth.CPFV angler success, as determined by catch per angler hour, generally increased in all ports in 1992 compared to previous 1988-91 data (Reilly et al. 1993). However, port-specific areas of major concern were identified for chilipepper, lingcod, and black rockfish, and to alesser extent brown, canary, vermilion, yelloweye, widow and greenspotted rockfishes. These areas of concern included steadily declining catch rate, steadily declining mean length, and/or a high percentage of sexually immature fish in the sampled catch.Recent sampling of the commercial hook-and-line fishery in northern and central California indicates that most rockfishes taken by CPFV anglers are also harvested commercially.

    Description: The Central California Marine Sport Fish Project has been collecting angler catch data on board Commercial Passenger Fishing Vessels (CPFVs) fishing for rockfish or lingcod since 1987. The program depends on the voluntary cooperation of CPFV owners and operators. This fifth report in a series presents data collected in 1995, refers to historical data from 1987 to 1994, and documentstrends in species composition, angler effort, catch per unit effort (CPUE), and, for selected species, mean length, and length frequency.Angler catches on board central and northern California CPFVs were sampled from 12 ports, ranging from Fort Bragg in the north to Port San Luis (Avila Beach) in the south. Technicians observed a total of 1829 anglers fishing on 218 CPFV trips. These observed anglers caught 26,197fish of which samplers determined 22,888 were kept. Over 62% of these fish were caught at Monterey or Morro Bay area ports. Only 18 of 55 species comprised at least one percent of the catch. The top ten species in order of abundance were yellowtail, blue, olive, and rosy rockfishes, lingcod, and canary, widow, gopher, starry, and vermilion rockfishes. Blue and yellowtail rockfishes together comprised approximately 47% of the observed catch. Overall, rockfishes represented 35 species or 64% of the 55 identified species. By number, rockfishes comprised 91.9 % of the observed catch.All CPUE and length data collected since 1987 were partitioned into six location groups for each port area, based on a combination of location, bottom depth, and distance from the nearest port. This allowed examination of indicator trends without potential biases due to non-random trip selection or ontogenetic changes in depth distribution for certain rockfishes. Results indicate thatthe two primary species in the northern and central California CPFV fishery, blue and yellowtailrockfishes (accounting for 47% of all observed fish in 1995), are in reasonably good condition with no steady declines in either average catch per angler hour or mean length during the last 8 years. The primary species of concern are mainly shallow-water species impacted by a recently expanded commercial hook-and-line fishery or deep-water species (chilipepper and bocaccio) which are fished intensively by the commercial industry and have experienced recent statewide stock declines.Estimated total rockfish catch, adjusted by logbook compliance rates and on board sampling data, has declined significantly in all port areas since 1992. This is largely attributable to increased recreational fishing effort for salmon as well as coast-wide stock declines in several important commercially fished species. (112pp.)

    Description: The Central California Marine Sport Fish Project has been collecting angler catch data on board Commercial Passenger Fishing Vessels (CPFVs) fishing for rockfish or lingcod since 1987. The program depends on the voluntary cooperation of CPFV owners and operators. This third report in a series presents data collected in 1993, refers to historical data from 1987 to 1992, and documents trends in species composition, angler effort, catch per unit effort (CPUE), and, for selected species, mean length and length frequency.Angler catches on board central and northern California CPFVs were sampled from 15 ports, ranging from Crescent City in the north to Port San Luis (Avila Beach) in the south.Technicians observed a total of 2385 anglers fishing on 248 CPFV trips. These observed anglers caught 29,622 fish of which Technicians determined 27,421 were kept. Over 60% of these fish were caught at Monterey or Morro Bay area ports. Only 18 of the 58 species each comprised at least one percent of the catch. The top ten species in order of abundance were blue, yellowtail, chilipepper, rosy, widow, canary, greenspotted, bocaccio, and vermilion rockfishes and lingcod. Blue and yellowtail rockfishes, and chilipepper, together comprised over 50% of the observed catch. Overall, rockfishes represented 35 species or 59% of the 58 identified species.In general, 1993 data indicated that in all port areas CPFV fishery resources, with a few exceptions, were in a viable and sustainable condition, similar to the previous 6 years. This study identified nine species, lingcod and eight rockfishes, with areas of concern which were primarilyport-specific. Six of these ranked among the 10 most frequently observed species, five were schooling or migratory species, two were nearshore species, and three were offshore species. Trends of most concern continue to be declining catch per angler hour (CPAH) - of yellowtailrockfish in the Bodega Bay area, lingcod in shallow locations near the Monterey area, and yelloweye rockfish in the San Francisco area, as well as decreasing mean lengths of canary rockfish in the Monterey area and brown rockfish in the Morro Bay area. Populations of black rockfish, the species presently of greatest concern in the CPFV fishery, showed some positive signs this year. Also on the positive side, the Monterey and Morro Bay areas experienced anincreased availability of newly-recruited smaller, juvenile vermilion rockfish in observed catches. Total catch estimates were within values observed in previous years. (132pp.)
