This refers to the report Jaffna fishermen lose hope in tussle with Tamil Nadu counterparts (Feb.16). Deep-sea trawling is banned by many nations due to its adverse environmental impact on marine ecology. The giant, heavy-duty nets that are dragged over the seafloor at depths of more than a kilometre are known to mutilate the corals that provide habitats for fish and other marine organisms. With each trawler typically crisscrossing an area of ocean around 33 sq.km, one can well imagine the damage being caused. In addition, trawlers have been known to discard giant nets at sea which in turn become death traps for countless marine organisms. Both countries need to approach the issue from an ecological point of view.
