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.

澳大利亚正在对渔业管理采取生态系统办法。然而，要采用这种方法，迫切需要更好地了解鲨鱼、鳐和银鲛（软骨鱼纲）的生物学、生态学和种群动态。软骨鱼类是对捕捞影响反应最敏感的物种之一。本提案的结果将有助于确定软骨鱼类副渔获物物种因渔具捕获、渔民处理和海上丢弃的影响而死亡的情况。这项工作将有助于为今世后代保护生物多样性和维持生态系统的结构和功能。
