MONOCULTURE OF GREY MULLETS IN COASTAL SALTWATER

The paper gives the results of a set of six monoculture experiments attempted on mullets, Liza vaigiensis and Valamugil seheli, fed on artificial diet composed of rice bran and groundnut oilcake in equal proportions at a rate of 5-10% body weight. The experiments were conducted in saltwater ponds at Mandapam and covered in all a period of three years. L. vaigiensis stocked at an estimated density of 50000|ha yielded at the rate of 569|kg|ha|year with the survival estimated at 72.9%. V. seheli, which was dealt with in all the subsequent five experiments, with stocking densities varied from 22000 to 40000lha, has given a yield varying from 59 kg|ha|315 days to 782 kg|ha|265 days, with survival rates varying from 18.3 to 81.2%.
