    Description: Methods and materials used to tag and recapture jack mackerel, Trachurus symmetricus, off the coast of southern Ca1ifornia and Baja California, Mexico, are described. Tagging, recapture, and movement data resulting from this program are reported. Analysis of these data indicates substantial movement of jack mackerel within the range of the California fishery and suggests a seasonal inshore-offshore movement pattern. (13pp.)

    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 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: 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.

    Description: The catch landed and effort expended by private-boatsport fishermen in southern California were studiedbetween April and June 1982, in order to determine theimpact of this segment of the sport fishery on localmarine resources. Fishermen returning from fishingtrips were interviewed at launch ramps, hoists, andboat-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 213,000 organisms were landed by 102,000anglers and 3,300 divers. The major components of thecatch were white croaker, Genyonemus lineatus (56,000landed); and Pacific mackerel, Scomber japonicus (43,000landed). Together these two species made up almost one half of the estimated southern California sport catch.Anglers' compliance with size limit regulations wasvariable. 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.)

    Description: An extensive study of fishing activity stemming from privately-owned boats was conducted during 1981 in order to determine the magnitude and impact of this segment of southern California's marine sport fishery. Anglers and divers returning from fishing trips were interviewed at launch ramps, boat hoists, and boat-rental facilities from Pt. Conception to the Mexican border. Information on fishing catch and effort was used to calculate statistical estimatesof total catch, total effort, catch of preferred sportfish species, and compliance rates for legal minimumsize limits.An estimated 1,013,000 organisms were landed during355,000 fishing trips. The major components of thisyear's catch were 1) Pacific mackerel, Scomber japonicus, 231,000 landed; 2) Pacific bonito, Sarda chiliensis, 157,000 landed; 3) white croaker, Genyonemus lineatus, 148,000 landed; and 4) rockfish, Sebastes spp., 142,000 landed. These fishes contributed two-thirds of the total catch.This year anglers were favored by mild weather andthe summertime appearance of migratory game fishes,resulting in higher than usual effort levels andabove average catch rates for favored game species.

    Description: The catch landed and effort expended by private-boat sportfishermen were studied in southern California between Julyand September 1981, in order to determine the impact of onesegment 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 356,000 organisms were landed by 134,000 anglers and 5,400 divers. The major components of the catch were Pacific mackerel, Scomber japonicus, 89,000 landed; Pacific bonito, Sarda chiliensis, 82,000 landed; white croaker, Genyonemus lineatus, 34,000 landed; and bass, Paralabrax spp., 33,000 landed. These species made up two-thirds of the total catch.Anglers' compliance with size-limit regulations was variable. Approximately 88% of all measured bass were legal size. The proportion of legal-size white seabass, Atractoscion nobilis, rose from 9% last quarter to 18% this quarter, but dropped for California halibut, Paralichthys californicus, from 79% to 66%. Divers' compliance with size limits on abalone, Haliotis spp., rose slightly from 89% to 91%. (31pp.)

    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 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: 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: Since the inception of a sac-roe fishery for Pacific herring, Clupea pallasi, in 1973, the California Department of Fish and Game (Department) has annually assessed the status of the state's two largest spawning populations ofherring in Tomales and San Francisco Bays. Each year the Department's Pacific Herring Research Project estimates spawning biomass, determines the age structure of the spawning population, examines growth and general condition, estimates the relative abundance of young-of-the-year herring, and monitors the biological aspects of the catch. This information, along with environmental factors, is considered and used to set the harvest quota for the following season's fishery.San Francisco Bay supports the largest spawning population of Pacific herring in California, as well as the largest commercial herring fishery. Spawning generally occurs fromNovember through March, in the intertidal and shallow subtidal zones of the central and southern regions of the Bay. This report presents work conducted during the 1993-94 spawning season and continues the time series of information for the San Francisco Bay spawning population. (36pp.)

The 1980 landings are the lowest since 1976 when 1,545.5 mt (3,400,191 lb) were landed. Area A (Eureka-Crescent City) landings dropped to 1,234 mt (2,716,147 lb) from 1,842.5 mt(4,053,605 lb) landed during the previous season. Area B-1 (Fort Bragg) landings totaled 79.3 mt (174,395 lb) from catches made during the last 9 days of the season. Only 100 lb were reported caught in Area B-2 (Bodega Bay). Record landings of 719.1 mt (1,582,107 lb were made in Area C (Morro Bay-Avila), surpassing the previous record of 391 mt(864,667 lb) landed in 1979. In Area A a record 80 vessels, 34 double-rigged and 46 single-rigged, made shrimp deliveries during the season. Average catch per hour was a very low .ll mt (234 lb) and .20 mt (446 lb) for single-rig and double-rig vessels, respectively. In Area C averagecatch per hour was .25 mt (557 lb) and .21 mt (462 lb) for single-rig and double-rig vessels, respectively. Area A shrimp catches were dominated by 1-year-old shrimp in percent by number throughout the season. The age composition in Area C shifted from predominately 2-year-old shrimpin April, May, and June to predominately 1-year-old shrimp for the remainder of the season. Area A was closed for one month from June 1 to July 1 because closure criteria of less than .16 mt (350 lb) per hour for two consecutive weeks was met and year class composition exceeded 70% of year-old shrimp. The season was closed for the year on August 25 whenthe catch per hour and percent 1-year-old shrimp criteria was exceeded again.(22pp.)

    Description: The catch landed and effort expended by private-boatsport fishermen was studied in Los Angeles Countybetween October and December 1980, in order todetermine the impact of one segment of the sportfishery on local marine resources. Fishermenreturning from fishing trips were interviewed atlaunch ramps, hoists, and boat rental facilities.This report contains quantitative data and statisticalestimates of total effort, total catch, catch ofpreferred species, and length frequencies for thosespecies whose catches are regulated by minimum sizelimits.An estimated 94,000 organisms were landed by 22,000anglers and 1,200 divers. The major components of thecatch were Pacific mackerel, Scomber japonicus, 29,000landed; white croaker, Genyonemus lineatus, 17,500landed; and Pacific bonito, Sarda chiliensis, 11,500landed. These three species comprised two-thirds ofthe total catch.Anglers' compliance with size limit regulations wasvariable. Nearly 80% of all measured bass, Paralabraxspp., were legal size, but only 50% of the Californiahalibut, Paralichthys californicus, were legal size.Divers showed much better compliance with the sizelimit regulations: 96% of all California spinylobsters, Panulirus interruptus, were legal size.

    Description: Previous studies suggest that ocean anglers are unableto identify many common marine fishes and that they frequently use nondesignated common names for those fisheswith which they are familiar.This paper discusses the ability of the anglers andcrew aboard commercial passenger fishing vessels (CPFV) toidentify 22 fishes caught off southern California and relates this ability to fishing experience and frequency. Implications to resource management are also discussed.Most CPFV anglers were inexperienced and could identifyonly a few of the species. However, as experience increased,the scores improved. Vessel crew members scored higher thanthe most experienced anglers.The inability of anglers to identify marine fishes andthe widespread use of nondesignated and often confusingcommon names help to explain why some fishery managementregulations of the California Department of Fish and Gameare relatively ineffective.

    Description: Anglers frequently violate sport fishing regulations out ofignorance, by mistake, or by deliberate action. To determinewhether unfamiliarity with the regulations plays a major part in this problem, we asked anglers on privately-owned,trailerable boats at launch ramps and boat hoists a series of questions which tested their knowledge of the regulations.We found that on any winter weekend about 30% of the anglerson private-boats knew none of the size limits, 50% knew atleast three of the six size limits, and 4% knew all of thesize limits. Only about 25% of the anglers kept a copy ofthe regulations on their boats for reference when fishing.The results of the survey indicate that greater effort mustbe expended to familiarize sport fishermen with the fishingregulations.

    Description: Although we continue to monitor permanent stationson a regular basis, we have suspended our 30-m2random subtidal and 1/4-m2 random intertidal studiesduring this interim year. The 1/4-m2 random subtidal study is being continued and we have added a new subtidal method of determining fish abundance.Giant red sea urchin, Strongylocentrotus franciscanus,numbers continue to decline at their last "stronghold"in our subtidal study area, permanent station15. The recruitment of juvenile blue rockfish,Sebastes mystinus, appears to be either late orlow this year in our study areas. The most abundantfish, so far, from the new method of assessment,are adult blue rockfish, kelp greenling,Hexagrammos decagrammus, and gopher rockfish,Sebastes carnatus.Various trends of abalone abundance at the permanentintertidal stations, increasing at some,decreasing at others, were observed during thisquarter.Sea otters, Enhydra lutris, seem to have reachedtheir annual springtime peak in abundance duringApril and May. Several otters were seen raftingand foraging around and near the intake covebreakwaters, apparently becoming emboldened tohuman presence. (18pp.)
