Fish Bulletin No. 106. Age and Length Composition Pacific Coast Catches, Sardines and Pacific Mackerel 1955–56 and 1956–57 Seasons and the Northern Anchovy 1954–55 Through 1956–57 Seasons
Abstract
The age and length composition of the catches of three of the more important pelagic marine fishes of California are included in this bulletin.
The age and length composition of the sardine catch has been determined annually since the 1941–42 season. Data previous to the 1955–56 season have appeared in nine reports. Age determinations of sardines are made from scale samples.
The report on age composition of the Southern California catch of Pacific mackerel is the sixth in a continuing series since the 1939–40 season. Age determinations of Pacific mackerel are made from otoliths.
Age and length composition of the northern anchovy catch has been determined since the 1952–53 season. The present report is the second in a continuing series. It includes length and age data for the commercial catch and the live bait catch. Age determinations are made from scale samples.
