鱼类杂交及基在生产上的应用,在国内外都有报导。我国鱼类杂交工作主要是在鲤科鱼类进行,这与我国传统的养殖对象大多属于鲤科鱼类有关。通过鱼类远缘或种内杂交可以获得“杂种优势”,或培育新的优良品种。鱼类杂交育种需要的周期长,由于鱼是生活在水体里,不便观察,且容易逃散,若无严格的管理制度和科学的养殖方法,往往是半途而废的。 Fish hybrids and their application in production have been reported both at home and abroad. China’s fish hybridization is mainly carried out in the carp, which with most of our traditional breeding objects belonging to carps. You can get “heterosis” through distant or intraspecific crossings of fish, or cultivate new good varieties. Cross-breeding of fish requires a long period of time. Because the fish live in the water, they are not easily observed and easily escaped. Without a strict management system and scientific farming methods, they are often abandoned halfway.
