Food Habits Database (FHDBS)

Metadata Updated: September 22, 2023

The NEFSC Food Habits Database has two major sources of data. The first, and most extensive, is the standard NEFSC Bottom Trawl Surveys Program. During these surveys, food habits data are collected for a variety of species. Additionally, "process-oriented" cruises are conducted periodically to address specific questions related to the feeding ecology of the fish in the ecosystem.

Both sources provide primarily stomach content information; composition, total and individual prey weights or volumes, and length of prey. Additional information associated with each fish predator is also collected. Other databases encompass the prey fields of these fish, and include zooplankton, ichthyoplankton, and benthic surveys.
