Abstract

Global fish production exceeds 170 million tons in 2023, and provides a high-quality protein source for humans. However, various factors may contribute to hypoxic stress and anemia, which contribute to yield loss in fish production. Elevated red blood cell counts or activation of erythropoiesis are well-known responses to anemia and hypoxia stress in fish. Erythropoiesis is the process of formation of new erythrocytes, from hemopoietic stem cells, through the differentiation of erythroblasts, to the maturation of red blood cells. This step-wise process is governed by complex transcriptional, post-translational, and epigenetic programs in response to extracellular signals. This review summarizes developing knowledge regarding erythropoiesis in teleosts, including the wave and site of erythropoiesis, specification of the erythroid lineage, and molecular regulation mechanisms. A summary of research gaps is presented, to be addressed by future research on teleosts. Understanding erythropoiesis facilitates improved fish husbandry and selective breeding of hypoxia-tolerance fish, to ultimately contribute to increased production.

远志鱼类的红细胞生成:神奇的生物过程
2023 年,全球鱼类产量将超过 1.7 亿吨,为人类提供优质蛋白质来源。然而,各种因素都可能导致缺氧应激和贫血,从而造成鱼类产量损失。红细胞计数升高或红细胞生成活化是众所周知的鱼类贫血和缺氧应激反应。红细胞生成是指从造血干细胞到红细胞分化,再到红细胞成熟的新红细胞形成过程。这一循序渐进的过程受复杂的转录、翻译后和表观遗传程序控制,并对细胞外信号做出反应。本综述总结了有关长尾目动物红细胞生成的新知识,包括红细胞生成的波浪和部位、红细胞系的规格以及分子调控机制。本文总结了研究中存在的不足,并将在未来的远洋鱼类研究中加以解决。了解红细胞生成过程有助于改善鱼类饲养和耐缺氧鱼类的选育,最终有助于提高产量。

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.
