attribute NC_GLOBAL summary String SWFSC FED Mid Water Trawl Juvenile Rockfish Survey: CTD 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 survey's data on YOY Pacific whiting has also been used in the stock
assessment process. To assist in obtaining additional northward spatial
coverage of YOY Pacific whiting off Oregon and Washington, in 2001 the
Pacific Whiting Conservation Cooperative in cooperation with the NOAA NMFS
Northwest Fisheries Science Center began a midwater trawl survey patterned
after the NOAA NMFS SWFSC Fisheries Ecology Division's (FED) existing survey.
Both surveys work cooperatively together each year in order to resolve
interannual abundance patterns of YOY rockfish and Pacific whiting on a
coastwide basis, which provides expedient, critical information that can be
used in the fisheries management process.

The large quantity of physical data collected during the surveys (e.g., CTD
with attached transimissometer and fluorometer, thermosalinometer, and ADCP)
have provided a better understanding of the hydrographic conditions off the
California coast and analysis of these data have been distributed through the
publication of NOAA NMFS Technical Memoranda.
