Summary
Blood sera from char (Salvelinus alpinus L.) inhabiting four Welsh lakes were analysed for genetic polymorphisms. The transferrin and esterase loci demonstrated genetic similarities in continuous populations and genetic differences between geographically isolated populations. Whilst the genetic information obtained for the char of Llynnau Peris and Padarn would not seem to call for measures to inhibit mixing of individuals from both lakes in the event of the destruction of Llyn Peris as a suitable char habitat, it is suggested that, in the interest of conservation of natural gene pools, the distinct populations of Llynnau Bodlyn, Cwellyn and Peris/Padarn should be maintained in isolation and not altered by stocking with char from elsewhere.
