Description
| - Food composition, selectivity and competition between carp (Cyprinus carpio) and perch (Perca fluviatilis) were studied under conditions of pond farming technology with the application of wheat as a supplementary feed. Carp preferred feed wheat, which composed 52.7 - 65.7 % of food ingested. Positive selectivity was proved for copepods and chironomid larvae, whilst avoidance appeared for bioseston, rotifers, Bosmina longirostris, Daphnia galeata and many benthic invertebrates except above mentioned chironomids (Helobdella stagnalis, Hydracarina, Caenis robusta, Mystacides and Ceratopogonidae). Perch showed predatory (cannibalistic) feeding pattern with 83.9 - 92.6 % portion of small fish in the food bulk. Perch did not consume smallest food particles like bioseston and rotifers. Negative selectivity was proved also for copepods and small benthic animals like water mites and larvae of Caenis robusta, Mystacides, Chironomidae and Ceratopogonidae. On the other hand, bigger invertebrates (Asellus and larv
