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

滴灌用自清洗网式过滤器排污压差计算方法   总被引:3,自引:0,他引:3  
对滴灌用自清洗网式过滤器排污压差进行了计算,分别得出了80目和120目过滤器总压差值,并与实测值进行了对比,结果表明两者基本一致;详细分析了流量、含沙情况和过滤时间等约束条件对排污压差的影响规律,结合试验获得了清水和浑水水头损失变化曲线,在保证水头损失不发生急剧上升前提下,给出了两种目数过滤器最佳排污压差值.  相似文献
