EFFECT OF ZIZIPHUS JUJUBE LEAF EXTRACT ON GILL OF FRESH WATER FISH OREOCHROMIS MOSSAMBICUS

Abstract

An investigation was carried out to evaluate the effect of selected plants (Ziziphus jujube) supplemented feed on the effect parameters and specific effect rate of Oreochromis mossambicous. Two experimental feeds were prepared by adding 10 ml of leaf extract to the basal diet and one control feed without plant extract. The fishes were supplemented with these feeds for 30days and the results were obtained for every 15 days once. The data were analyzed using standard deviation and the means were separated using least significant differences. The fishes fed with Ziziphus jujube supplemented feed showed maximum increase in gill congestion and specific growth rate. The maximum increase in length was observed in the fishes that were supplemented feed .This study indicated that inclusion of plant ingredients in fish feed resulted in superior effect performance and the formulation of plant based diet for fish will provide new opportunities.
