Classification of Fisheries

Description

Fish is a rich source of animal protein and its culture is an efficient protein food production system from aquatic environment. The main role of fish culture is its contribution in improving the nutritional standards of people. Fish culture also helps in utilising water and land resources. It provides inducement to establish other subsidiary industries in the country. Catching fish is the main occupation for numerous persons living nearby coastal areas, reservoirs and rivers.

Fisheries can be categorised into two types – ‘Fin’ fisheries and ‘Non-Fin’ fisheries. The former is fisheries of true fish, whereas the later is the fisheries of organisms other than true fish like prawn, crab, lobster, mussel, oyster, sea cucumbers, frog, sea weeds, etc. Fin fisheries can be further categorised into two types – ‘capture fisheries’ and ‘culture fisheries’.
Classification of fish has undergone much change over the last few decades partly because so many groups are poorly known. There are many conflicting hypotheses of relationships some based on conflicting evidence between morphological studies and molecular studies; however progress is being made and there are many areas of basic agreement. Accepting that there is a great deal of variety within the world of fish helps us in understanding them better.

This book thoroughly covers all basic information on the subject of fisheries to make the reader up-to-date with the latest in this field where proliferation of scientific information. The author is a well qualified senior authority on the subject.
