About this Dataset

FRD Trawl Database

Specimens captured in trawls by the SWFSC Fisheries Resources Division during surveys for coastal pelagic species. Most tows were targeted for coastal pelagic species (e.g., sardine, anchovy, mackerels) using a Nordic trawl (2023 and before) or a Multi-Function Trawl net (2024 and after) on the surface at night. The database includes information on individual trawls, catch data with identification to various taxonomic levels depending on species, length frequencies, and individual length and weight data.
