Endogenous Fishing Mortalities: a State-Space Bioeconomic Model [PDF]
, 2017 A methodology that endogenously determines catchability functions that link fi shing mortality with contemporaneous stock abundance is presented. We consider a stochastic age-structured model for a fishery composed by a number of fi shing units ...
