Enhanced Biological Sampling Data

This is a database of a variety of biological, reproductive, and energetic data collected from fish on the continental shelf in the northwest Atlantic Ocean. Species sampled in this database thus far include winter flounder, yellowtail flounder, summer flounder, haddock, cusk, Atlantic wolffish, and Atlantic herring. Data are collected from fish provided principally from fishermen participating in the NECRP Study Fleet. Some fish are taken from other NECRP research studies, and a small number from NEFSC surveys and surveys by MADMF and URI GSO. The catch location data is provided in views from the relevant FVTR, SVDBS, or other tables for a few cooperative research or external programs. The biological data includes general physical data (weights, lengths, organ weights, macroscopic maturity stage), age data, and other reproductive data. Measures collected from preserved gonad samples includes data for estimation of fish fecundity (oocyte counts and diameters) and from grading gonad histology for determination of maturity and seasonal reproductive status. In addition, relative measures of energetic condition are collected (including tissue wet weight and dry weights and bioimpedance data), and for some fish food habits data were collected in the first 18 months of data collection.
