Biological and economic vulnerabilities of fixed TACs in small pelagics: an analysis for the European anchovy (Engraulis encrasicolus) in the Gulf of Cádiz
A coupled population dynamics and economic model is applied to the purse seine anchovy-fishery in the Gulf of Cádiz. The model simulates the population dynamics, landings and profits on a probabilistic frame. These simulations are used to assess the biological and economic consequences of an individ...
