Description Snake mackerels form by-catch in deep sea trawls and gillnets with an annual average production of 106 t during
2004 - 2006 in Tuticorin area. Fishery occurred almost round the year with peak during November - March. Fishery and
biology of the dominant species, Neoepinnula orientalis was monitored during 2004 - 2005. Peak spawning and recruitment
of the species was during December - March period. Growth parameters, L∝ and K are estimated as 31.6 cm and 0.68/year
respectively. K value indicates that fish growth is relatively slow. Natural mortality estimate (M) is 1.38, total mortality
(Z) 1.59 and fishing mortality (F) 0.21. The exploitation ratio (E) is low being 0.132. These estimates indicate that the stock
is at its early stage of exploitation and have large scope for future commercial exploitation. As a preliminary step in this
direction, the extent of stock abundance, biomass and distribution of the stock needs to be assessed. Being a slow growing
species in cold habitat, considerably long time is required for stock multiplication. These factors have to be taken into
consideration while planning for exploitation of snake mackerels in future.
