The status of the California Barracuda resource and its management

The California barracuda, Sphyraena argentea, has been fished commercially for over 70 years. Peak landings were made during the early 1920's and have since declined to an incidental level. The present interest in barracuda centers around its desirability as a game species. Recent estimates of barracuda abundance indicate the population is at a low level and in need of increased management efforts. (21pp.

Southern California partyboat sampling study Quarterly Report no. 1

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 partyboats with primary emphasis given to California barracuda, Sphyraena argentea; yellowtail, Seriola dorsalis; white seabass, Cynoscion nobilis; and rockfishes, Sebastes spp. (22pp.

Southern California partyboat sampling study Quarterly Report No. 4

From 1 April through 30 June, 1976, Department personnel made 146 trips aboard southern California partyboats. A total of 18,218 fishes from 76 species was identified and measured. Otoliths were removed from 674 rockfish carcasses for use in age determination studies. The 10 most common species sampled during this quarter represented 85.2% of the total number of fishes measured. These were, in order of importance: bocaccio, Sebastes paucispinis; kelp bass, Paralabrax clathratus; Pacific bonito, Sarda chiliensis; barred sand bass, Paralabrax nebulifer; chilipepper, Sebastes goodei; California barracuda, Sphyraena argentea; olive rockfish; Sebastes serranoides; white croaker, Genyonemus lineatus; ocean whitefish, Caulolatilus princeps; and vermilion rockfish, Sebastes miniatus. Pacific bonito and California barracuda partyboat landings exceeded those of the entire 1975 season, and sampling data indicate the average length of barracuda caught from partyboats was significantly larger than that of the previous season.

Southern California partyboat sampling study Quarterly Report no. 3

During the period January 1 to March 31, 1976, Department personnel 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 California barracuda, Sphyraena argentea, and 18 sablefish, Anoplopoma fimbria. The five most common species sampled during this period represented approximately 79% of the total number of fishes measured. These were, in order of importance; bocaccio, Sebastes paucispinis; chilipepper, Sebastes goodei; olive rockfish, Sebastes serranoides; greenspotted rockfish, Sebastes chlorostictus; and vermilion rockfish, Sebastes miniatus. Bocaccio alone accounted for 52% of the sampled catch. (15pp.

Southern California partyboat sampling study Quarterly Report no. 8

Between April 1 and June 30, 1977, 125 trips were sampled aboard southern California partyboats by Department personnel. A total of 14,842 fishes belonging to 72 species was identified and measured. Otoliths were removed from 134 rockfish carcasses representing 20 species for age deterination studies. The 10 most common species sampled during the quarter accounted for 76.9% of the catch. Individually, the most common were Pacific mackerel, Scomber japonicus (16.9%); kelp bass, Paralabrax clathratus (14.5%); bocaccio, Sebastes paucispinis (11.4%); Pacific bonito, Sarda chiliensis (10.3%); barred sand bass, Paralabrax nebulifer (5.6%); olive rockfish, Sebastes serranoides (5.3%); chilipepper, S. goodei (4.0%); California barracuda, Sphyraena argentea (2.9%); and ocean whitefish, Caulolatilus princeps (2.8%). Fishing effort switched from "rockcod" to surface activity as it did during the second quarter of 1976 (26pp.
