Shift of fish and mollusc communities under stress conditions were studied. Particularly in eutrophic lagoons, with strong internal recycling, the organic enrichment and high macrophyte biomass lead to dystrophic summer crisis. These processes cause a severe reduction of production and specific diversity. For cockle populations, biochemical criteria for the separation of species, habitat preference and trophic niche segregation were studied.
