Open-design Recirculating Systems for Zebrafish Culture     

《Aquacultural Engineering》2018

The zebrafish is an established vertebrate-animal model in biomedical research. Currently, their mass culture is mainly done using systems provided by commercial suppliers. Commercial systems are compact, recirculating, and use auto-cleaning tanks. These features minimize space use, labour cost, and water wastage; thus, facilitating maintenance of a large number of zebrafish using minimal resources. However, the often considered costs associated with these systems often impose a barrier to current and prospective researchers, especially those with limited funds or working in labs with no access to institutional centralized zebrafish culture facilities. In contrast to commercial systems, custom-made zebrafish maintenance systems are also described in the literature. To distinguish custom-made system from commercial systems, we termed them as “open-design” systems. Open-design systems are cost-effective, modular, and frequently being improved by zebrafish researchers. However, for further development and to present them as a viable option for zebrafish researchers around the world, a review of their current status and technical understanding is required. Here, we compile the disparate data on the purpose and technological development of the open-design systems. We believe this review will be a valuable resource for all zebrafish users and help streamline the open-design technology for zebrafish culture.  相似文献   

规模化畜牧养殖对生态环境的破坏及防治     

郑书高 《畜牧兽医科学(电子版)》2021,(4):182-183

近年,畜牧养殖业蓬勃发展,过去的区域化散养已经基本不存在,养殖结构逐渐向集约化、一体化、规模化过渡,养殖规模也逐渐增大。养殖副产品肉、蛋、奶等极大满足了人们的生产生活,养殖中产生的尿液、粪污对生态环境造成极大影响。为促进规模化养殖实现绿色健康发展,该文分析规模化畜牧养殖对生态环境的破坏及防治措施。  相似文献
