Celem pracy było zbadanie kumulacji Cu w tkankach narybku karpia (Cyprinus carpio) w zróżnicowanych warunkach termicznych. Materiał doświadczalny stanowiły karpie o średniej wadze 36-50 gramów, średniej długości ciała 10 cm. W doświadczeniu zastosowano pięć różnych stężeń miedzi w wodzie (0,05; 0,1; 0,5; 1,0; 5,0 ppm Cu). Jako źródło miedzi użyto w doświadczeniu CuSO₄. Stwierdzono, że w miarę wzrostu...
