Abstract
The authors examined the extent of genetic variability in a hatchery sample of Astacus leptodactylus, at the level of some enzyme gene loci. The enzymes, studied by means of starch gel and cellulose acetate gel electrophoresis, were PGI, PGM, TO and esterases. Apart from one Esterase zone, all these enzymes appeared monomorphic. The authors hypothesize that such variability reduction can be attributed to a hatchery effect, as has been demonstrated for other animals bred intensively. They propose the adopting of electrophoretic techniques, as an important practical contribution to Astacid culture, for the control of genetic variation of hatchery products.
