Abstract

Crab fisheries play a crucial role in global fishery economics, but they heavily rely on wild catches. With the decline and exploratory limits of wild populations, expanding the scale and production of aquaculture becomes vital for the sustainability of crab fisheries. The development of crab aquaculture encounters significant dietary challenges, stemming from suboptimal formulated feeds and inefficient feeding management. Leveraging insights from crab foraging behaviours offers a promising solution to these issues; however, progress is hindered by a lack of comprehensive behavioural data and the underappreciation of these insights in aquaculture. To bridge this gap, we systematically examine the progress in studies of crab foraging behaviour, analysing the influences of predators, prey, and environmental characteristics, and discuss possibilities for future research and development in the field by combining these findings with the demands of aquaculture. This review identifies a discrepancy in research focus, with inadequate emphasis on the major cultured species and their behavioural responses to factors limiting aquaculture productivity, aiming to enhance our comprehension of crab foraging behaviour and facilitate growth in the crab industry.

重要却被忽视:螃蟹觅食行为的研究进展及其对水产养殖的影响
螃蟹渔业在全球渔业经济中发挥着至关重要的作用,但它们严重依赖野生捕捞。随着野生种群的减少和探索极限的降低,扩大水产养殖的规模和产量对螃蟹渔业的可持续发展至关重要。螃蟹水产养殖的发展遇到了饮食方面的重大挑战,这些挑战源于不理想的配方饲料和低效的饲养管理。利用螃蟹觅食行为的洞察力为解决这些问题提供了一个前景广阔的方案;然而,由于缺乏全面的行为数据以及对水产养殖中这些洞察力的认识不足,进展受到了阻碍。为了弥补这一差距,我们系统地考察了河蟹觅食行为研究的进展,分析了捕食者、猎物和环境特征的影响,并结合这些发现和水产养殖的需求,讨论了该领域未来研究和发展的可能性。这篇综述指出了研究重点的偏差,对主要养殖物种及其对限制水产养殖生产力因素的行为反应重视不够,旨在提高我们对螃蟹觅食行为的理解,促进螃蟹产业的发展。

期刊介绍: Reviews in Aquaculture is a journal that aims to provide a platform for reviews on various aspects of aquaculture science, techniques, policies, and planning. The journal publishes fully peer-reviewed review articles on topics including global, regional, and national production and market trends in aquaculture, advancements in aquaculture practices and technology, interactions between aquaculture and the environment, indigenous and alien species in aquaculture, genetics and its relation to aquaculture, as well as aquaculture product quality and traceability. The journal is indexed and abstracted in several databases including AgBiotech News & Information (CABI), AgBiotechNet, Agricultural Engineering Abstracts, Environment Index (EBSCO Publishing), SCOPUS (Elsevier), and Web of Science (Clarivate Analytics) among others.
