Recently, eel recirculation systems have provoked increasing attention in intensive fish culture, especially concerning animal welfare. "Aquaculture", "Intensive Culture", and "Recirculation Systems" are often confused with each other. This study, first of all, differentiates among these terms. The economic relevance of aquaculture in the Federal Republic of Germany is demonstrated by figures. A tendency towards intensive methods can only be seen in trout and eel culture. The problems of recirculation systems are explained comprehensively. Particular emphasis is laid on the conflict between theoretical suitability of intensive fish production and the absence of commercially working systems. At present, intensive fish culture does not pose a serious animal welfare problem in Germany. However, it is necessary to define the biological requirements of fish concerning their optimal accommodation in aquaculture facilities. According to the Law for the Protection of Animals, these requirements have to be laid down in an ordinance. Only then control is possible as to whether aquaculture systems fulfill fish welfare demands.
最近，鳗鱼循环水养殖系统在集约化养鱼中引起了越来越多的关注，尤其是在动物福利方面。“水产养殖”“集约化养殖”和“循环水系统”这几个术语常常相互混淆。本研究首先对这些术语进行区分。通过数据展示了德国联邦共和国水产养殖的经济相关性。集约化养殖方式的趋势仅在鳟鱼和鳗鱼养殖中可见。循环水系统的问题得到了全面解释。特别强调了集约化鱼类生产的理论适用性与缺乏商业化运行系统之间的矛盾。目前，集约化养鱼在德国并未构成严重的动物福利问题。然而，有必要明确鱼类在水产养殖设施中最佳养殖条件下的生物学需求。根据《动物保护法》，这些要求必须在一项条例中予以规定。只有这样，才能对水产养殖系统是否满足鱼类福利需求进行管控。
