By-catch of cold-water corals from an Experimental Trawl Survey in three seamounts within NAFO Regulatory Area (Divs. 6EFG) during year 2004
By-catch of cold-water corals from a Trawl Experimental Survey developed during 2004 in three NAFO seamounts was examined. Three hauls were carried out over two peaks located in Divs. 6EF. In this area, catches of commercial resources were negligible and by-catch of corals was recorded (degraded pie...
