Abstract
  • Main fishing gear in Thailand was otter board trawls. More than 70% of the total Thai fishing vessels had been using this fishing gear, as well as push net which was restricted targeting for demersal resources. Due to the 2.5 cm fine mesh size, juvenile economic species had been caught and sold as trash fish. Another important fishing gear which had conflict in utilization of fishery resources in Thailand was anchovy fishery, also using fine mesh size incurring by catches of juvenile economic species sold as trash fish. Von Bertalanffy growth function and length-weight relationship were employed in estimating the economic losses of these by catches of juvenile economic species. The loss of these economic species was estimated to be 10.82% of the usual fishing cost in case of anchovy purse seiner while it could be as high as 25.55% in case of light luring anchovy purse seine. For otter board trawler, this loss was estimated as high as 90.42% of the fishing cost, while they were 19.64% and 816.84% in case of push netters.
