Abstract/Description: | Myctophids form bycatch in deep sea shrimp trawls with an annual average catch of 2668 t during 2009 - 2011 in Kerala coast. Fishery occurred almost round the year with peak during November - February. Fishery and biology of the dominant species, Diaphus watasei was monitored. Peak spawning and recruitment of the species was during January-August. Growth parameters L∞ and K are estimated as 15.06 cm and 0.8 per year respectively. These values indicate that the species growth is relatively fast. Natural mortality estimate (M) is 1.21, total mortality (Z) 1.68 and fishing mortality (F) 0.47. The exploitation rate (E) is low being 0.279. These indicate that the stock is at its initial stage of exploitation and there is large scope for enhancing their commercial exploitation. The stock abundance, biomass and distribution of the resource need to be assessed. These factors have to be taken into consideration while planning for exploitation of myctophids in future. |
