| Abstract: | This thesis Entitled Studies on the Utilization of selected Species of sharks. The present study is the result of work carried out for 5 years, during the period from April, 1983 to March 1988. The materials were collected from the catches of the Government of India vessels, operated along the south west coast of India and landed in the Integrated Fisheries Project, Cochin—16. The sharks were caught by different types of gears such as bottom trawls, pelagic trawls, long line etc. A number of species of sharks were landed during this period and three species were selected for the present study namely Scoliodon palasorra (bleeker 1853, grey Shark), Carcharhinus limbatus (valenciennes 1839,black tip shark ) and centrophorus granulosus (bloch and schneider 1801 ,spiny shark). During this study period the quantity of shark utilized was 12,55,942 kg out of which 9.71% used for the production of Dressed shark; 36.21% for the production of Fillets; 49.09% converted into Dried shark and 4.99% was domesticallyy marketed as whole form. Besides this 526 kg of dried shark fin and 289.25 kg of shark fin rays were produced.The effect of Smoking of shark fillets and minced meat at different temperature were also studied during this period. Canning of cooked shark meat, smoked fillets and fish balls were carried out in media like brine, vegetable oil, tomato sauce etc. The quality of smoked fillets in vegetable oil was found superior to other canned products from shark meat.During this study an attempt was also made to evaluate the commercial processing of shark resources and found feasible. |
