Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch

澳大利亚正在采用生态系统方法进行渔业管理。然而，为了采用这种方法，迫切需要更好地了解鲨鱼、银鱼和嵌合体(软骨鱼类纲)的生物学、生态学和种群动态。软骨鱼类是对捕鱼影响反应最敏感的物种之一。本提案的结果将有助于根据渔具捕捞、渔民处理和海上丢弃的影响确定软骨鱼副渔获物的死亡率。这项工作将有助于保护生物多样性，为今世后代维护生态系统的结构和功能。

Australia is adopting ecosystem approaches to fisheries management. However, to embrace such an approach there is an urgent need for better information on the biology, ecology and population dynamics of sharks, rays and chimaeras (class Chondrichthyes). Chondrichthyan species are among the most sensitive in their response to the effects of fishing. Results from the present proposal will contribute to determining mortality of chondrichthyan bycatch species in response to the effects of capture in fishing gear, handling by fishers and discarding at sea. The work will contribute to biodiversity conservation and maintenance of ecosystem structure and function for present and future generations.
