Isozyme analysis demonstrates a high proportion of hybrids in a hatchery stock of peled (Coregonus peled) from Czech Republic

Whitefish (Coregonus lavaretus) and peled (C. peled) reared in a hatchery in Czech Republic were sampled and examined for genetic purity of their breeding stock. Pyloric caeca number did not permit identification of specimens, because ranged 131-256 in whitefish and 88-141 in peled. Number of gill r...

Summary:Whitefish (Coregonus lavaretus) and peled (C. peled) reared in a hatchery in Czech Republic were sampled and examined for genetic purity of their breeding stock. Pyloric caeca number did not permit identification of specimens, because ranged 131-256 in whitefish and 88-141 in peled. Number of gill rakers ranged from 24 to 34 in whitefish and from 48 to 67 in peled, and it could be considered as a species-specific identification marker. Electrophoretic examination of enzyme products of the diagnostic loci showed that over 30 percentage of fish morphologically classified as peled were biochemically identified as whitefish/peled hybrids
