Abstract

For a scientific study of the fishing grounds, information regarding the different categories of fishes, catch composition, etc., is essential. However, at present such information is not available from the log reports of the vessels Kalyani I-V of the Deep Sea Fishing Board, Government of West Bengal. The fish catch of these vessels are grouped into different classes and the weights relating to only " A " class category and some of the large sized fishes—Muraenesox telabonoides, sharks, rays and skates are available from the marketing section of the Deep Sea Fishing Board. Hence it has been attempted in the present paper to evolve a method for obtaining the species-wise weights of the remaining classes of fishes. Data on the catch composition based on the weights of the sample trays were collected from the landing centre, shore-base station. Catches of Kalyani IV dated 21-4-1962 have been analysed in particular and the results are presented to evolve a suitable methodology.
