Estimating fishing-related mortality and designing sustainable management protocols for shark fisheries in Northern Australia

鲨鱼的经济价值极高，2004年仅新台币的上岸渔获量就超过1000万元。全世界对高质量蛋白质的需求不断增加，因此必须进行适当管理，以免出现世界上其他大多数鲨鱼渔业所出现的过度捕捞现象。拟议项目将提供关键信息，指导今后作出审慎和知情的管理决定。收集关于在这种渔业中捕获的更稀有和更易受影响的非目标物种的信息的额外好处将确保减少任何负面影响。该项目还将提供关于我国北部邻国非法捕鱼的潜在影响的信息。

Sharks are extremely valuable economically, with the landed catch in the NT alone exceeding $10 million in 2004. The increasing world demand for high-quality protein will necessitate appropriate management so that over-exploitation does not occur as it has in most other shark fisheries worldwide. The proposed project will provide key information that will direct careful and informed management decisions well into the future. The added benefit of collecting information on the rarer and more susceptible non-target species caught in this fishery will ensure that any negative impacts are reduced. The project will also provide information on the potential impact of illegal fishing by neighbouring countries to our north.
