Despite their global distribution across major oceans, biological and fisheries information related to the crocodile shark (Pseudocarcharias kamoharai) is still scarce. The crocodile shark has become a frequently observed bycatch shark in many commercial fisheries. Their catch rates might be underreported by commercial fisheries, maybe because of the species’ small size and low commercial value. Moreover, stock assessment of crocodile shark has not yet been conducted, greatly due to lack of data, and their stock status, movement and genetic connectivity are still poorly known. Previous works have shown that crocodile shark has a low reproductive rate (often 4 pups reported), therefore, fishing mortality caused by fisheries targeting economic important species such as tuna, may cause their population to greatly decline. Major tuna Regional Fishery Management Organization (RFMO), have implemented non-retention of shark species. However, specific measures related to crocodile shark is lacking. Even though it is listed as Least Concern by the International Union for the Conservation of Nature (IUCN) Red List, effort must be directed towards the conservation and management of its population in their range of habitat. In other to avoid a stock collapse for this species in the future, this work summarized existing information on the state of the fishery and biology information for this species and have proposed future research directions to fill in missing information gaps to conserve this crocodile shark’s population from declining as has been the case with many other shark species.

尽管它们遍布全球各大洋，但与鳄鱼鲨有关的生物和渔业信息（Pseudocarcharias kamoharai) 仍然稀缺。鳄鱼鲨已成为许多商业渔业中经常观察到的兼捕鲨鱼。商业渔业可能低估了它们的捕获率，这可能是因为该物种体型小，商业价值低。此外，由于缺乏数据，还没有对鳄鱼鲨进行种群评估，对其种群状况、运动和遗传联系仍知之甚少。此前的研究表明，鳄鱼鲨的繁殖率较低（通常报道为 4 只幼崽），因此，针对金枪鱼等经济重要物种的渔业造成的捕捞死亡率可能会导致其数量大幅下降。主要金枪鱼区域渔业管理组织 (RFMO) 已实施不保留鲨鱼物种。然而，缺乏与鳄鱼鲨相关的具体措施。尽管它被国际自然保护联盟 (IUCN) 红色名录列为最不关心的物种，但必须努力保护和管理其栖息地范围内的种群。此外，为了避免该物种在未来出现种群崩溃，这项工作总结了有关该物种渔业状况和生物学信息的现有信息，并提出了未来的研究方向，以填补缺失的信息空白，以保护该鳄鱼鲨的种群免受威胁。与许多其他鲨鱼物种的情况一样。
