Description The marine ecosystem is dynamic and the variations several abiotic and biotic factors directly
and indirectly affect the fish stocks and their population structure. Spawning and recruitment
success is to a large extent linked to these environmental variations. It is well known that resources
occupy a particular habitat because of their preference to the environmental variables prevalent
there and also due the availability of food. We have large shoal forming small pelagic fishes like the
sardines and anchovies and the deep water large pelagic and demersals occupying the marine
ecosystem from the upper pelagic zone to the benthic realms. Fishing is one of the major activities
directly impacting the fish stocks and fishery records show several cases of overfishing leading to
stock collapses. Definitely, fishery management tools have supported revival of several of these
stocks but have failed to do so in few others. Almost equally important in inducing the biological
changes that control maturation, spawning and recruitment are the some ocean atmospheric
processes which change inter-annually in the tropics.
