Possibilities of intensive breeding of pike perch (Sander lucioperca) and european perch (Perca fluviatilis) in common duoculture

The aim of this thesis is to assess the growth rate (and suitability) of different, (in terms of percentual representation) duoculture stocking of Euroasian perch and pikeperch, when they are breeding in the experimental conditions of intensive aquaculture. It is expected to test at least 3 different duoculture stocking and 2 single (control) stocking (100% representation of pikeperch and Euroasian perch). Culture will take place in special experimental tanks which allow quantification of uneaten feed to counting the daily feed intake. Following the own testing of growth rate (including variability), the evaluation of feed intake, survival, feed conversion, and condition indices will be performed. The main tested hypothesis is to find differences in growth and other parameters between Eurasian perch and pikeperch stocking. The own experimental testing will be preceded by a literature search on the topic
