| Comments |
Introduced in 1882. Reintroduced in 1960. Widely used for aquaculture and for stocking lakes (Ref. 1739). Frequent introductions and escapes from captivity make it difficult to estimate wild population numbers. Weakly affected several species of salmon family and rheophilous cyprinids (Ref. 55773). Also Ref. 13364. |
