Abstract

 It is hypothesized that hake requieres an ecosystem approach to fishery management for its recovery. The objective is to carry out simulations with a multispecific ecotrophic model, with two stages of hake, to understand the trophic interactions of hake with its preys, predators and competitors. Simulations with biological and environmental factors, suggested that population reduction of hake is attributed more to biological factors (trophic relationships and fishery pressure) than to environmental factors. In general, biomass model projections suggested that low levels of hake stock present a limited resilience.
