Fish egg counts and standardized counts for eggs captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes only tows where one or more eggs were captured for the species selected by the user, i.e., no "zero" tows. The "Egg Counts" table includes all tows by species, i.e., both positive and negative tows.

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.

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.

This dataset contains detections of acoustic tagged fish from two general locations: Golden Gate (east and west line) and Pt. Reyes. Several Vemco 69khz acoustic receivers were deployed at each of these general locations. The Golden Gate receivers were deployed beginning in April 2005 while the Pt Reyes receivers were deployed beginning in July 2008. The tagged fish in the dataset include all fish tagged by NOAA Santa Cruz and some green sturgeon tagged by NOAA in the Columbia River and Willapa Bay. Only a subset of these tagged fish were detected at the Golden Gate and Pt. Reyes. There are detections of many more fish that are not in the list of tagged fish in this dataset.

SWFSC FED Mid Water Trawl Juvenile Rockfish Survey: Station Information and Surface Data.
Surveys have been conducted along the central California coast in May/June
every year since 1983. In 2004 the survey area was expanded to cover the
entire coast from San Diego to Cape Mendocino. The survey samples a series
of fixed trawl stations using a midwater trawl. The midwater trawl survey
gear captures significant numbers of approximately 10 rockfish species during
their pelagic juvenile stage (i.e., 50-150 days old), by which time annual
reproductive success has been established. Catch-per-unit-effort data from
the survey are analyzed and serve as the basis for predicting future
recruitment to rockfish fisheries. Results for several species (e.g.,
bocaccio, chilipepper [S. goodei], and widow rockfish [S. entomelas]) have
shown that the survey data can be useful in predicting year-class strength
in age-based stock assessments.

The project’s objective is to document movement patterns and survival rates of Chinook salmon, steelhead, green sturgeon, and other fish from several sources in the Central Valley of California. Juvenile salmonids from hatcheries or wild caught are implanted with small acoustic transmitters and the location of the fish are recorded on receivers that are placed throughout the watershed from Redding to the Golden Gate. Over 70 receiver locations with over 150 receivers monitor the movement of these fish. These receivers record the date, time, and unique identification number of transmitters that pass within listening range of the receivers. The first acoustic tagging studies began in 2006 and continue today.

Fish larvae counts and standardized counts for eggs captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]) . Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes only tows where one or more larvae were captured for the species selected by the user, i.e., no "zero" tows. The "Larvae Counts" table includes all tows by species, i.e., both positive and negative tows.

The Fisheries Ecology Division (FED, https://swfsc.noaa.gov/GroundfishAnalysis/) of the Southwest Fisheries Science Center (SWFSC) has conducted a midwater trawl survey off central California since 1983 with the primary goal of developing pre-recruit indices for young-of-the-year (YOY) rockfish (Sebastes spp.). The survey also samples numerous other components of the epipelagic micronekton, including other YOY groundfish (such as Pacific hake, Merluccius productus, and sanddab, Citharichthys spp ), coastal pelagic fishes (such as Pacific sardine, Sardinops sagax, and northern anchovy, Engraulis mordax) and other forage species. Additional details regarding the survey methods and results are described in Ralston et al. (2015) and Sakuma et al.
