Individual specimens measured (weight in grams and length in mm) and sexed from mainly targeted species caught during SWFSC-FRD fishery independent trawl surveys of coastal pelagic species. Individuals are categorized as random or non-random samples. Does not include species with length bins recorded in the CPS Trawl Life History Length Frequency dataset.
An aerial monitoring program was conducted during the period 1962 - 2007 in cooperation with aerial spotters working for the commercial purse seine fleet. Flights were conducted throughout the year to estimate abundance of pelagic fishes off California and Baja California, Mexico. Measurements were recorded for each identifiable species in 10'-longitude by 10'-latitude blocks. This data file describes which ocean blocks over which a pilot passes on a particular day and flight.
In 1983, the groundfish analysis project began a series of yearly cruises designed to assess the annual abundance of juvenile rockfish along the central California coast. Midwater trawls were collected and CTDs performed during late spring of every year since 1983. Initially the cruises were restricted to the San Francisco area; however, in the early 2000's, the geographic range was extended to include San Diego through Fort Bragg.
Samples collected using the Continuous Underway Fish-Egg Sampler, known as CUFES. The data include numbers of anchovy, sardine, jack mackerel, squid, hake, and unidentified fish eggs captured, and associated environmental.
