Analysis of Fish Production Status and Marketing Structure in Aliyar Reservoir, Tamil Nadu

Abstract

The present study is an attempt to document production trend and marketing channels in Aliyar reservoir. Secondary data were analysed and reported that the Annual Growth Rate of stocked fish production (IMC and Common carp) decreased by 16%, but an attractive issue was that AGR of non-stocked fish production (exotic and indigenous species) increased by 49%. Mrigal was observed to dominate in total fish production. The study revealed that negative relationship (r -0.4416) existed between total seeds stocked and fish production, while positive relationship was observed in species wise fish production of Rohu (r 0.6557), Mrigal (r 0.8736) and Common carp (r 0.5991) except Catla which proved that stocking density influences production of these fish species. Catla production was negatively (r -0.2141) correlated with stocking density. Hence, this study recommends that reduction in stocking density of Catla seeds may help improve total fish yield. The present study revealed that the reservoir has well organized marketing system with 31 fresh fish marketing stalls.
