Potential fishing zones in the marine environment

As in the case of terrestrial animals, the marine fauna including fish also respond, in varying degrees, to changes in the environmental conditions. The physical parameters such as sea water temperature, density, hydrostatic pressure, horizontal and vertical movements of water masses, the intensity of solar radiation and chemical parameters including the saltiness of seawater, dissolved gases and biological factors such as the availability of food and occurrence of predators decide the occurrence, distribution, abundance, reproduction and mortality of individual species in space and time
