Homogeneity of body length composition of Antarctic krill within the commercial haul
Abstract: The homogeneity of krill length composition in commercial trawl catches (hauls) was ... investigated by comparing length compositions from different parts of the same haul. There was no significant ... difference (P>0.05) in 53 out of 60 hauls. Therefore it is concluded that sampling from one part of the ... haul provides a reasonable estimate of length composition in the entire haul as a whole. In contrast to ...

PRELIMINARY RESULTS OF TRIALS TESTING MODIFIED LONGLINE GEAR ‘TROTLINES’ IN PRESENCE OF CETACEANS IN SUBAREA 48.3
cetaceans were present. This difference increased with increasing abundance of cetaceans highlighting the ... potential of this gear to reduce cetacean depredation. 3. By-catch to catch ratio was greater by number for ... Spanish system lines when cetaceans were present during hauling. 4. A large percentage of skates caught on ... . Consequences of a move to trotlines would therefore lead to: i. Some positive benefits by reducing cetacean ...
