Description Today, when so much is being said and written about our interests in the ocean, it
is particularly important to retain our perspective. Of course, the present pattern is likely
to change, although how rapidly or dramatically we do not know. What is certain is that
we shall use the ocean more intensively and in a greater variety of ways. Our greatest
need is to use it wisely. The general goal of ecological research to which marine biology
makes an important contribution, is to achieve an understanding and to tum to our
advantage all the biological processes that give our planet its special character. Marine
biology is focussed on the problems of biological production, which are closely related to
problems of production in the economic sense as well. Our most compelling interest is
often narrower. It lies in ocean life as a renewable resource, primarily of protein-rich
foods and food supplements for our domestic animals and to us and of secondary
materials and drugs. At this point, it is time to inquire about the future expectations from
the ocean which is or three dimensional environments provides protein rich seafoods
alternate to agricultural products from land. Other than this, nonliving resources such as
minerals, oil, medicinal properties of the various marine organisms etc. are resources we
collect from the sea.
The present harvest of marine living resources from the world oceans is about 87
million tonnes in 1996 (Anon., 1998). More than 90% of this harvest is finfishes: the rest
consists of whales, crustaceans, molluscs and other invertebrates. It is now a common
knowledge that fish is one of the few major foodstuffs showing an increase in global
production that continues to exceed the growth rate of the human population. This
increase has been accompanied by changing patterns of use. Although some products of
high unit values that includes luxury foods, such as shellfish, have maintained or even
enhanced their relative economic importance and the trend is that moderate catch is used
directly for human consumption and the bulk is reduced to fishmeal for animal feed and
manure. There are also large aggregations of pelagic animals that live further down and
are associated particularly with the "Deep Scattering Layer" (DSL). the sound-reflecting
stratum observed in all oceans which has vast potential to provide exploitable resources.
