Hi all,

I am looking for information from N. Am. and Eur. on loss of genetic
diversity in stocked recreational fish species, due to low numbers of
founders. At present there is a massive push to stock native
"recreational" species in Australian waters. The main problem being that
it only takes a few genereations to lose vital genetic diversity and then
these fish can breed freely (in some areas this is praised as a way to
boost wild stocks) with wild stock fishes.

If anyone have references or other informaiton on maintaining genetic
diversity in stocked fishes please send it along.

thanks.
