Hoagland, P. and D. Jin, A model of bycatch involving a passive use stock, Marine Resource Economics 12(1):11-28, 1997

We develop a simple extension of the theory of multispecies fisheries management to analyze a problem where one fish or animal stock has no commercial market but instead is valued passively. We interpret a typical bycatch problem as a standard multispecies fisheries management problem, and we develop a multispecifies model incorporating both monetary losses associated with bycatch and variable biological relationships. We examine the behavior of the model with a numerical example focusing on the case of the bycatch of spotted and other dolphins in the eastern tropical Pacific (ETP) yellowfin tuna fishery.
