For fisheries staff, vessel operators, and researchers reviewing unwanted catch, this chat calculates bycatch rates from catch and effort figures, compares species and gear patterns, and weighs mitigation options for a fishery. Paste the relevant numbers and describe the gear and target species. You leave with a rate summary, a comparison of possible measures, and questions to investigate in the next fishing period.

What it writes
- Bycatch rate and species summary
- Mitigation options comparison table
- Next-period monitoring checklist
How to use it
Include species counts, fishing effort, gear type, location, and dates in your first message. State whether effort means hours, sets, or trips so rates use the right denominator.
What you bring
- Catch counts by species
- Fishing effort and trip dates
- Gear type and target species
- Paste the figures into the chat
A good fit for
- Reviewing observer records after an increase in turtle captures
- Comparing bycatch rates across two trawl gear configurations
- Choosing measures to reduce juvenile fish catch in a target fishery
Ways to start
A few requests this Agent can handle.
Our shrimp trawlers caught 18 juvenile red snapper in 60 hours last month. Calculate the bycatch rate and suggest what other figures I should compare.
Compare these options for reducing sea turtle capture in a Gulf shrimp trawl: TEDs, shorter tow times, and seasonal closures.
In 40 gillnet sets, we caught 12 harbor porpoises and 2,400 target fish. Help me summarize the bycatch rate and identify useful next steps.
