杂交鱼类在繁殖能力方面存在着很大的差别。此大致可分三类:完全能育(某些(鱼将)形目的属间杂种),完全或有障碍能育(鲟科、鲤科及其他鱼类一些的种间和属间杂种),完全不育(美国中弓鱼科杂种)。杂种能育力的大小同亲本的亲缘关系,即交配品种在分类学上的近远,并不总相对应。例如,有些属间杂种的能育力高出属内杂种。获得完全能育的杂种最多的机会是在如下情况:交配品种的染色体数量相等,同出一源,在配子成熟过程中能行结合。反之,在染色体数量不等、结合过程有障碍时,便出现不同程度的不育性。
Hybrid fishes have very different reproductive abilities. This can be broadly categorized into three categories: complete fertility (some hybrids), complete or impaired fertility (some interspecific and interspecific hybrids of sturgeon, carp and other fish), Completely sterile (Acrocephalus hybrids in the United States). The size of hybrid fertility is similar to the parental relationship, that is, the taxonomic proximity of mating varieties does not always correspond to each other. For example, some intergeneric hybrids are more fertile than their inbreds. The chances of obtaining the most fertile hybrids are in the following cases: the number of mating varieties is equal to the number of chromosomes, the same out of a source, and the combination of ripening in gametes. Conversely, in the range of chromosome number, the process of binding obstacles, there will be different levels of infertility.
