Abstract

A fishery resource is a self-renewable living natural resource in a dynamic habitat. Even if the resource was in a static environment and there was no fishing, since it is a living resource it will maintain itself by the adjustments of its inherent biological characteristics like growth, recruitment and mortality which are probably inter-related in some way. When fishing exploits a resource it changes the mortality and therefore the behaviour of the system. The changes in environment may alter all the biological characteristics of a resource and its behaviour pattern. The aim of the fundamental research is to have a full knowledge of all characteristics of a resource and their interaction to changes generated by fishing and dynamic changes in the environment. The purpose of a countinuing resources survey is, however, limited in character but none the lesi useful. A continuing resources survey is like quality control which keeps a watch on the processing behaviour and warns the industry when the processing is out of control. From the results of the fundamental research whatever be the stage, a certain knowledge of the resource and its behaviour pattern is obtained and the resource is viewed as a system obeying certain laws and having some attributes. The purpose of a continuing resources survey is to collect information on these attributes of the system and maintaining a watch on the system, to see if the estimates of attributes are obeying the laws, any departure from which will at once be a warning that the pattern of the system has changed. The fundamental research and continuing resources survey are complementary to each other and must exist on a continuing basis. The operation characteristics of a continuing resources survey have been illustrated with examples taken from Indian fisheries.
