摘要: Trawling remains a controversial method of fishing due to the perceived lack selectivity trawl net and resultant capture huge quantity diversity non-target species, including endangered species such as sea turtles, coupled with its effect on marine ecosystem. The impacts trawling physical, chemical biological environment ecosystem by-catch discards remain poorly documented for tropical waters. In India, landed at harbours are utilized mainly production manure animal feed. Further, reduction devices have not been implemented in field. This review article, besides analysing impact trawling, highlights need adopting policies practices that reduce level by-catch, ecosystem-based management ensure long-term sustainability oceanic resources, adoption precautionary approach emphasis reducing, if possible avoiding discards.
