摘要：

Electrophoretic analysis of juvenile salmonids from south‐west England revealed the presence of natural hybrids between Atlantic salmon, Salmo salar L., and brown trout, Salmo rrurra L., within three of five rivers. Amongst 409 juvenile ‘salmon’, 1.2% were hybrids, and of 150 juvenile ‘trout’ sampled, 2.0% were natural hybrids. In one river, similar hybridization levels in ‘salmon’ parr samples were found in two successive years. Levels of hybridization are high when compared with most similar studies, especially others within the United Kingdom. Possible factors influencing this are discussed.
