Introduction: The brown trout (, L)—its origin, distribution and economic and scientific significancronments. This has led to a major degree of polymorphism in this species, which has been classified in the past under different scientific names (Melhaoui, 1985; Elliott, 1989, 1994). However, the interpretation of the polymorphy of the trout remains delicate in terms of genetic differences (Krieg,

Main characteristics of the biology of the trout (, L.) in Lake Léman (Lake Geneva) and some of its main physical, chemical and biological characteristics of this subalpine, mesoeutrophic lake, have been detailed in a report (C.I.P.E.L., 1984). The most important physical data concerning the basin flowing into the lake are shown in Fig. 1. Twenty-three species of fish have been reported (Laurent,

Genetic diversity and the management of natural populations of brown troutbility confers different adaptive values on individuals making up the species. The objective of genetic improvement is to select and propagate the genotypes showing the best adaptive value in a given production system. Selective breeding methods have been established for most domesticated species or

It is therefore important, according to this definition, to verify, at regular intervals, if the objective has been reached, to examine the consequences by comparing the results obtained and those predicted.

Conclusion: Current ideas on the biological basis for management of trout populations (, L.)ber 1988. The scientists expressed, by this decision, a desire to review the diverse studies on trout and to transmit the acquired knowledge in a synthesized form, which could be understood by those with little biological knowledge.
