摘要

Theresults of the studies on stock assessment made on I I commercially important pelagic fish grwps such udas oil sardine, lesser sardines, whitebaits, mackerel, tunas and billfishes, seerfihes, pomfmts, carangids, udribbonfishes. Bombay duck and Hilsa shadbased on the data of 1984-88 arepresented. Detailed analysis of the udproduction and estimatedcatchable potential of major pelagic fish groups from the initial stages of mechaniza- udtion torccent years and in the traditional fishing areasof both thecoasts of India areindc The species which udhavereached theoptimal level of exploitation and those which hold potential for fiuther exploitation have been uddescribed. Theresults indicatedthat the stocksof oil sardine, mackerel,tunas, sec?rfishes, pomfnts and Bombay udduck in the traditional fishing grounds areexploited to or beyond their maximum sustainable yield, whereas udlesser sardines, whitebaits and all& species, oceanic tunas frequenting the shelf waters. carangids and udribbonfishes have potential for marginal increase. Options open to obtain incnase in production to the level of udpotential estimatesare briefly discussed,and the necessity of beaupost-harvest utilion of these finfishes udpointed wt.
