A trophometric index (TMI) is proposed to estimate fish density, biomass and production in Mediterranean reservoirs. It consists of simple and integrated environmental variables such as the form index (IF = S/V ), the volume percentage of water with sufficient oxygen to sustain fish life, conductivity, chlorophyll a concentration and perimeter, the synergic effect of which explains the fish structure and accounts for the functioning of the ecosystems. This index was tested in eight reservoirs… CONTINUE READING
