丢弃是指在捕鱼作业过程中被抛回大海的那部分渔获物。本研究以北海渔业为例，对丢弃问题的后果、原因和可能的解决方案进行了评估。渔民在捕捞作业中的直接目标，以及对减少丢弃措施的预期收益的低信心，促进了非选择性拖网的使用，而配额制度执行不力则加剧了丢弃数量。结论是，要想长期解决丢弃的生态和经济代价，就必须降低丢弃率，制定捕捞机会奖励办法可以促进使用更具选择性的捕捞技术。(C)2004爱思唯尔有限公司。保留所有权利。
Discards refer to that part of the catch returned to the sea during fishing operations. This study assesses the consequences, causes, and potential solutions to the discard problem using the example of North Sea fisheries. Fishermen's immediate objectives during fishing operations and the low confidence in projected gains from discard reduction measures have promoted use of unselective trawls while the poor enforcement of the quota system has exacerbated discard quantities. It is concluded that a reduction in discard rates is required for a long-term solution to the ecological and economic costs of discarding and the development of fishing opportunity incentives can promote the use of more selective fishing techniques.
