Experimental observations on feeding of Puntius pulchellus (Day) and utility of the species in possible eradication of aquatic plants



Experimental observations on feeding of Puntius pulchellus (Day) and utility of the species in possible eradication of aquatic plants



Mysore Journal of Agricultural Sciences 16(1): 85-95



In feeding experiments with fingerlings and young Puntius pulchellus, a carp of peninsular Indian rivers, fingerlings ate between 21.6 and 100% soft weeds (Vallisneria, Hydrilla, Potamogeton and Chara), and up to 5.9% Agrostis grass in 20 to 26 days; daily intake of weeds was 1.096 g. Young fish (1 year old) ate 88.69% soft weeds and 14.88% grass in 20 to 38 days; daily intake of weeds was 36.30 g.
