ENVIRONMENT-VENEZUELA: Farewell, Trawl-Fishing
By Humberto Márquez
“Trawling is killing off fish species. In our case, we fish with hooks, catch a ‘pargo’ (sea bream), try again, catch a ‘mero’ (grouper), and clean them as we go. We used to fill the boats in a single night, but for years now that hasn’t happened, and sometimes we come back empty-handed,” Manuel González told IPS.
González is a veteran member of the Fishers’ Association of Río Caribe, a town on the Caribbean coast 550 kilometres northeast of Caracas.
Groups of fisherfolk have been organising marches in the capital, some of them driving trucks carrying their boats, to show their support for the Law on Fisheries and Aquaculture, amended by Chávez in March by a decree-law banning trawl-fishing.
Before the amendment, the previous law promulgated by Chávez in 2001 only prohibited trawling less than six miles (10 kilometres) from the mainland or less than 10 miles (16 kilometres) from island shores.
But the amended law bans trawl-fishing in all Venezuelan waters, where González said “Italian and Spanish ships used to trawl, not only Venezuelan fishing vessels.”…
“The reason for the new law is ecological. In Venezuela, trawlers damage over 68,000 square kilometres of seabed a year. The United Nations Food and Agriculture Organisation (FAO) warns that if this continues, marine species will be wiped out by 2048,” Giménez said.
