Reproductive data for groundfish

The ROCKFISH database houses data from rockfish species collected by the SWFSC FED along the California coast as part of a reproductive study originating in the winter of 2009 to assess spatial, environmental and maternal effects on egg production. Basic morphometric data, reproductive state, fecundity, condition, age, sampling location and dates are recorded. In addition, historic datasets are being compiled and assimilated into the ROCKFISH database to compare current fecundity estimates to those in the 1950s, 80s, and 2000s from various published and unpublished sources. Under construction are tables documenting an ongoing effort in production ageing of chilipepper rockfish collected by the NWFSC trawl survey to assess trends in mean size-at-age from the 1980s to current and estimate reader variability and error in age estimation.
