Major problems regarding traditional fisheries management in the context of rapidly declining stocks and degrading ecosystems and an urgent need for sustainable devolvement create an impetus for a fundamental change in ...

Environmental variability has a strong influence on marine fish stocks. Thus, management and harvest policies based on deterministic indicators, such as maximum sustainable yield (MSY), may be inappropriate facing such ...

The concept of optimum yield is applied to an age structured simulation model of the Scomberomorus cavalla (Mitchill) fishery in the western and southern Gulf of Mexico. Current yearly catch amounts to 2,600 tonnes and is ...

Biologic characteristics of schooling fish species explain why the rates of harvesting in pelagic fisheries are not proportional to the existent stock size and may exhibit no variation between the periods of fish abundance ...

An ecosystem analysis was developed focusing on resource exploitation and biodiversity conservation for the Northern Gulf of California. The main tools employed were a trophic ecosystem model and time dynamic simulations. ...
