    Description: A report is made on the feasibility studies of discriminating possible sub-populations, migratory patterns, and maturity of white seabass, Cynoscion nobilis. Biochemical investigations were encouraging and may prove useful in future studies of population structure. The low catch rate of white seabass in southern California precluded tagging substantial numbers of fish and studies of their migratory habits have been terminated until fishing improves.Insufficient numbers of fish also made successful completion of maturity studies impossible and this project is being held in abeyance at the present time.

    Description: During the period January 1 to March 31, 1976, Departmentpersonnel made 139 sampling trips aboard southern California partyboats. A total of 22,122 fishes from 73 species was identified and measured.Otoliths were removed from 1,536 rockfish carcasses representing 31 species for use in age determination.Sampling personnel tagged and released 68 Californiabarracuda, Sphyraena argentea, and 18 sablefish, Anoplopomafimbria.The five most common species sampled during this periodrepresented approximately 79% of the total number of fishesmeasured. These were, in order of importance; bocaccio,Sebastes paucispinis; chilipepper, Sebastes goodei; oliverockfish, Sebastes serranoides; greenspotted rockfish,Sebastes chlorostictus; and vermilion rockfish, Sebastesminiatus. Bocaccio alone accounted for 52% of the sampledcatch. (15pp.)

    Description: Estimates of the total yearly catch from the partyboat fishery have been collected and published on a routine basis since 1935. Important data relating to the size and age composition of this segment of the marine sportfishery have been lacking. As a consequence, a southern California partyboat sampling study was initiated on April 1, 1975. The main objective of this sampling is to identify and measure all fishes taken by sportsmen on partyboatswith primary emphasis given to California barracuda, Sphyraena argentea; yellowtail, Seriola dorsalis; white seabass, Cynoscion nobilis; and rockfishes, Sebastes spp. (22pp.)

    Description: From October through December 1976, Department personnelmade 160 sampling trips aboard southern California partyboats. A total of 25,574 fishes from 80 species was identified and measured. Also, otoliths were removed from 722 rockfish carcasses representing 28 species for use in age determination studies.The 10 most common species sampled were bocaccio, Sebastespaucispinis (33.3%); chilipepper, S. goodei (16.0%); oliverockfish, S. serranoides (6.1%); kelp bass, Paralabrax clathratus (4.6%); blue rockfish, S. mystinus (4.5%); Pacific mackerel, Scomber japonicus (4.4%); widow rockfish, S. entomelas (2.4%); vermilion rockfish, S. miniatus (2.0%); ocean whitefish, Caulolatilus princeps (1.9%); and greenstriped rockfish, S. elongatus (1.9%).The sampled quarter represented a transitional period inthe partyboat fishery during which effort shifted from "surface" fishing to deep water "rockcod" fishing.

A total of 15,827 fishes from 75 species wasidentified and measured.Otoliths were removed from 290 rockfish carcasses representing 23 species for use in age determination studies.The 10 most common species sampled during this quarterwere kelp bass, Paralabrax clathratus (22.9%); barred sandbass, P. nebulifer (13.7%); olive rockfish, Sebastes serranoides (12.0%); bocaccio, S. paucispinis (1l.6%); Pacific bonito, Sarda chiliensis (6.6%); California barracuda, Sphyraena argentea (5.9%); white croaker, Genyonemus lineatus (4.5%); blue rockfish, S. mystinus (2.9%); brown rockfish, S. auriculatus (2.8%); and ocean whitefish, Caulolatilus princeps (2.8%).Preliminary results from California partyboat logs indicate landings of Pacific bonito, California barracuda, kelp bass, and barred sand bass were significantly larger than those of 1975, while the low catch rates of yellowtail and white seabass remained approximately equal to those of the previous season.

Pacific bonito and California barracuda partyboatlandings exceeded those of the entire 1975 season, andsampling data indicate the average length of barracudacaught from partyboats was significantly larger thanthat of the previous season.

    Description: Fishing for live bait was originally introduced in 1910by Japanese albacore fishermen employing "blanket" nets. Thenorthern anchovy has always been the mainstay of the fisheryproviding 98 to 99% of the catch since 1957. Prior to thatthe Pacific sardine contributed 15 to 20% of the catch. Inpast years, when fishermen had difficulty locating fish, LosAngeles - Long Beach Harbor provided as much as 80% of theentire live-bait catch. A live-bait sampling program was initiated in 1955 by the Department of Fish and Game to maintain a closer check on the relative health of the anchovy resource. This sampling program provides the first visible indication of the yearly spawning success of northern anchovies and Pacific sardines. A brief summary of the fishing conditions from 1957 - 1973 are presented. (26pp.)

    Description: Partyboats were sampled during the months of May throughOctober 1972-1974 to collect length frequency data for California barracuda, Sphyraena argentea; Pacific bonito, Sarda chiliensis; white seabass, Cynoscion nobilis; and yellowtail, Seriola dorsalis. Age-length keys were applied to the data to estimate the age composition of each species and an analysis of variance was performed on the results. Ratio estimates were also computed to examine the variation due to month and port complex. The project provided background data for current stock assessments of these species.(Document has 25 pages.)
