Hybridization is widely used. However, for a long time, systematic theories and technologies related to hybridization in fish have been lacking. In this study, through long-term systematic research, we investigated and obtained the main rules regarding inheritance and reproduction related to fish distant hybridization. Furthermore, we established one-step and multistep breeding technologies that were suitable for interspecific hybridization and intraspecific hybridization. Simultaneously, we used these two breeding technologies to produce a batch of diploid fish lineages and tetraploid fish lineages and improved fishes. In addition, we widely discuss the methods, technologies and results of hybridization breeding, referring to the domestic and foreign literature on fish hybridization. We hope that this paper will be beneficial for the research and application of fish hybrid breeding.
杂交广泛应用于生物学领域。然而，长期以来，鱼类杂交的系统理论和技术一直欠缺。本研究通过长期系统研究，调查并获得了鱼类远缘杂交遗传和繁殖的主要规律，建立了适合于种间杂交和种内杂交的一步法和多步法杂交育种技术。同时，利用这两种杂交育种技术，培育出一批二倍体和四倍体的鱼类品系和改良种，对国内外鱼类杂交的文献进行查阅，对杂交育种的方法、技术和成果进行了广泛的讨论。希望本研究对鱼类杂交育种的研究和应用具有一定的参考价值。
