Specimens captured in trawls by the SWFSC Fisheries Resources Division during surveys for coastal pelagic species. The database includes information on individual trawls, catch data with taxonomic identification, length frequencies, and individual length and weight data. It is provided by the National Oceanic and Atmospheric Administration, Department of Commerce.
Use Cases
- Analyze catch composition and species abundance based on trawl catch data.
- Study length-weight relationships and population structure based on individual length and weight data.
- Compare fishing gear efficiency based on trawl type information (Nordic vs. Multi-Function Trawl).
- Model spatial-temporal distribution of pelagic fish based on trawl event data.
Strengths
- Includes catch data identified to various taxonomic levels.
- Contains individual specimen measurements (length and weight).
- Specifies trawl gear types used (Nordic trawl and Multi-Function Trawl).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
