Henry Franklin

One of the tuna fisheries resources of India that is economically utilised is the Kawakawa Euthynnus affinis. There was no more information on the stock status besides arrival data. As a result, the current study examined the sustainability of the kawakawa fishery in Tamil Nadu, India. For the years 2001 through 2020, annual catch and effort data were recreated. The stock exploitation was investigated by running surplus production models with catch, catch per unit effort (CPUE), and other life history data using the Catch-based MSY (CMSY), Bayesian state-space. Maximum Sustainable Yield (MSY) or biomass giving MSY (Bmsy) and fishing mortality giving MSY (Fmsy) of all the biological reference points.
