Get Involved by Donating Your Fish

Poseidon Fisheries Research is looking  to fill the gap of missing life history information for Hawaii’s coral reef species. We’re working with fish markets and fishermen to collect length, weight, age, growth, and maturity information for these local species.

We’re glad to accept any fish of the species pictured below and return your cleaned catch to you after we collect the necessary samples for our study.
