California Abalone Tradeoff Assessment
Public pressure to rebuild collapsed fish stocks, even in the face of rising food demands, necessitates a fresh look at the tradeoffs between conservation and fishing. This project examines the question “Is harvest compatible with stock rebuilding?” To answer this question we are constructing spatially-explicit, age-structured bioeconomic fish population and fishery models and identifying optimal management strategies (i.e., fishery regulations) in relation to a multi-criteria objective function that weights both economic (fishery) and conservation (stock rebuilding) interests. We are applying this approach to the proposed re-opening of the currently collapsed red abalone (Haliotis rufescens) fishery in the Channel Islands, California.
