4. Fish and Crustacean trophic ecology
Predator-prey relations play a fundamental role in defining the dynamics of the ecosystem, since they condition the energy transfer cycles among the different trophic groups present in the area and are necessary for the design of trophodynamic models. The study will be tackled using stomach content analysis of the main demersal fish occupying the top of the trophic chain, and decapod crustaceans dominating the community with an important role as scavengers or predators.
Feeding study using a trophometer to quantify stomach content volume.
