Application of biochemical markers and molecular-genetic methods in fishes

In aquaculture the identification of individuals, populations and gynogenet ic produced lines by genetic markers gets more and more important. Beside t he biochemical markers also the moleculargenetic methods of identification are useful, because they are more polymorphic and therefor more informative than the biochemical methods. In our Institute the biochemical are used si nce 1970 and the moleculargenetic methods since 1990 as well in warmblooded animals as in fishes. A review of the actual situation for the use of gene tic markers is presented.
