Status of the Jack Mackerel resource and its management

The jack mackerel, Trachurus symmetricus, resource off the west coast of North America is known to be large and widely distributed. 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 very rapidly due to higher priorities for analysis of sardine and Pacific mackerel data, and the apparent healthy condition of this resource. The California Department of Fish and Game initiated several projects in 1972 to resolve unanswered biological questions. (14pp.

Status of Pacific mackerel spawning population, 1975

Three methods were used to determine the Pacific mackerel population. The tag and recovery method estimated the population at 620 short tons. The other two estimates were based on regression techniques of partyboat catches and these results yielded 2,921 tons and 1,385 tons, respectively. All three estimates were below the 10,000 tons prescribed for a fishery and thus no harvest could be allowed. (14pp.

Maturation and growth of Pacific Mackerel, Scomber japonicus Houttuyn

The maturation of Pacific mackerel has never been documented clearly. Analysis of data reveals spawning can occur from March through October, but the majority takes place from April through August. During this April through August period, 22.5%, 65.7%, 75.1%, 84.7%, 84.2%, and 87.5% of the female fish were mature or maturing for Age Groups I, II, III, IV, V, and VI+ respectively. A von Berta1anffy growth curve and a weight-length curve were calculated. The weight-length curve was found to differ significantly from a curve previously published. (21pp.

Status of Pacific Mackerel spawning population, 1973

This is the first annual report of the status of the spawning population of the Pacific mackerel as required by Section 8388.3 of the Fish and Game Code. During 1972 and early 1973, several methods of determining population size were investigated as mechanisms for estimating the spawning population size of Pacific mackerel stocks north of Punta Eugenia, Baja California, and a method using tagging procedures proved to be the most acceptable. The estimate of the Pacific mackerel spawning population obtained by tagging procedures was 5,480 tons. This estimate agrees generally with those obtained from alternate methods in which previously computed spawning biomass estimates were correlated with partyboat catches in three different areas and the 1973 spawning biomass estimated from the resulting regression line. The estimates derived by these alternate methods are 6,970 tons, 4,730 tons, and 6,210 tons. All estimates are below the 10,000 ton spawning population minimum and thus there is no excess by which a harvest under Section 8388.5 of the Fish and Game Code could be allowed. (17pp.

Fish and bivalves at Bolsa Chica Marsh re-establishment project; Progress report III

The objectives of our fish and bivalve study are: 1. Determine changes in the number of species of fish and bivalves before Phase I and during Phase 1 at Bolsa Chica Marsh. 2. Determine if California Department of Fish and Game's predicted benefits in Phase I were achieved by increases in fish species. 3. Determine influences of water management practices upon fish and bivalve composition. Thirteen species of fish and five species of bivalves were collected from Inner Bolsa Bay and South Bolsa Slough. Deepbody anchovy, Anchoa compressa; jacksmelt, Atherinopsis californiensis; longjaw mudsucker, Gillichthys mirabilis; specklefin midshipman, Porichthys myriaster; round stingray, Urolophus halleri; banded chione, Chione californiensis; bentnose clam, Macoma nasuta; and common littleneck clam, Protothaca staminea have not been reported previously from Inner Bolsa Bay. Nine species of fish and four species of bivalves were collected from outer Bolsa Bay. Yellowfin goby, Acanthogobius flavimanus; longjaw mudsucker; tilapia, Tilapia mossambica; and bay pipefish, Syngnathus leptorhynchus have not been reported previously from Outer Bolsa Bay. (11pp.

Results of the 1977 southern California pismo clam survey

A Pismo clam, Tivela stultorum, survey was conducted in January 1977 on selected southern California beaches. Effort and catch information was collected through clammer interviews. Estimates for the two day survey were 1,596 clammers spending 2,506 hours to take 6,139 clams. Comparisons were made between the 1977 survey results and previous surveys. Clams were collected for length and age studies. Compliance to the 4.5-inch (114.3 mm) minimum size limit appeared to be good. (15pp.
