| Abstract |
Introduction of commercial purse-seining along Karnataka has increased the pelagic fish catch by about 30%. However, from the present trend, it is felt that there is over exploitation which may lead to depletion of stock. The author has analysed the data of commercial purse seining from 1977 to 1981 using the method of surplus production mode, taking catch-per-unit effort as an index of relative abundance of fish. The standing stock, maximum sustainable yield, the optimum effort and catch-per-unit effort were worked out separately for mixed species, sardine and mackeral. The economic level of exploitation and effort for maximum sustainable yield are also discussed. |
