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
