| 520 | 3 |a"Discarded fish generally go unrecorded in official statistics. Using direct observations at sea by observers, estimates of the amounts of discarding in the various domestic Newfoundland offshore fisheries were examined to pinpoint problem areas. In all cases, estimates of discards did not exceed 10% except for bycatch of turbot and redfish juveniles in the shrimp fishery. The estimates presented should be regarded strictly as minimum values because of the enforcement aspects of the observers' job. The presence of observers tended to deter or reduce discarding. Highest estimates of discards were seen in the 3NO cod fishery (7.5%), 3LNO American plaice (4.6%), 3LNO yellowtail (4.2%), wolfish (28% overall) and skate (99%). Most of the fish discarded were small which meant that larger numbers per unit weight were thrown back. Indications are that the problem may be more intense in the absence of observers." |
