Brown trout stocking experiment at the river Wulka
Abstract
In spring 2009 the river will be stocked by one year old brown trouts. three different strains will be stocked, 1000 indioviduals out of each strain. The selcted strains stem from geologically different rivers/hatcheries and temperature regimes etc. The trouts will be tagged by visible implant elastomere, where every strain will be given a different colour. within 2009-2011 the river will be electro-fished on four different dates, to contol survival and growth rates of the different strains. aim is to evaluate the performance of the three different strians to gain basic knowledge, how to build up a self sustaining brown trout stock for the river Wulka in the future.
