Abstract

The striped murrel (Channa striatus) is an economically valuable species in aquaculture due to its high price, medicinal properties, rapid growth, widespread consumer appeal, and ability to thrive in high-density intensive farming owing to its air-breathing capabilities. Despite these advantages, challenges in larval rearing hinder the production of high-quality fingerlings with increased survival rate. This review examines current larval rearing protocols for striped murrel, identifies bottlenecks, and explores digestive development during early stages to enhance understanding of its ontogeny. While advancements have been made, there are gaps in knowledge regarding the roles of specific genes and hormones during early development, and the impact of environmental factors on larval survival and metabolism. To address these gaps, this review draws an extensive knowledge acquired from studies on other fish species, examining digestive and metabolic genes, hormones, and environmental factors, with the goal of advancing larviculture practices for striped murrel. In addition, this review provides insights into the methodologies for studying the digestive system during early developmental stages of striped murrel larvae.

探索条纹鼠（Channa striatus）的本体发育和幼虫饲养

条斑鳢（Channa striatus）是水产养殖业中具有经济价值的鱼种，因为其价格高、有药用价值、生长迅速、对消费者具有广泛吸引力，而且由于其呼吸空气的能力，能够在高密度集约化养殖中茁壮成长。尽管有这些优势，但幼体饲养方面的挑战阻碍了提高成活率的优质鱼苗的生产。本综述研究了条纹短攀鲈目前的幼体饲养规程，找出了瓶颈，并探讨了早期阶段的消化系统发育，以加深对其本体发育的了解。虽然已经取得了进展，但在早期发育过程中特定基因和激素的作用以及环境因素对幼体存活和新陈代谢的影响等方面的知识仍存在差距。为了弥补这些差距，本综述从对其他鱼类物种的研究中汲取了大量知识，对消化和代谢基因、激素和环境因素进行了研究，旨在推动条纹短攀鲈的幼鱼养殖实践。此外，本综述还对研究带鱼幼体早期发育阶段消化系统的方法提出了见解。

期刊介绍： Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture. The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more. This is the official Journal of the European Aquaculture Society.
