Description Exploited fish stocks are assessed with the help of micro
analytic and macro models (Alagaraja, 1990). Catch in numbers (age
specific or length specific) or catch in weight and the corresponding
fishing effort expended are the main inputs to the fish population
models. The quality of this input data governs the performance
(predictive or interpolative) of the models and determines the
relevance of management decisions inferred from the stock
assessment studies.
Catches usually are estimated from sampling of commercial
landings. These sampling schemes are often complex and multistage
in nature. In India marine fish catch statistics are collected by the
Central Marine Fisheries Research Institute, Cochin through a
sampling system based on the theory of sampling(Bane~i, 1971).
Most of the catches are from the inshore regions and landed at about
2400 landing centres spread all along the coast line in the various
9
maritime states of India. Keeping pace with the changing pattern of
the fishery the mode of collection has also undergone change
periodically without any significant alterations in the basic structure of
the sampling design.
