Bioeconomic Interactions Between the Capture Fishery and Aquaculture
This paper builds on the work of Anderson (1985a). Interactions between the capture fishery and aquaculture are modeled in two different cases: (1) cultured fish has the same market value as wild fish, and (2) cultured fish has only a substitute value for wild fish.

Post-Capture Survival and Implications for By-Catch in a Multi-Species Coastal Gillnet Fishery

Over half the commercial gillnet catch was discarded, with discard rates of ~20% for target and >80% for non-target spec...
