Growth Response, Feed Utilization And Survival Of Fingerlings Of Heterobrancliiis Longjflhis Fertilized With Poultry Droppings And Cowdung.
ABSTRACT
The study was carried out to evaluate the effect of chicken droppings and
cow dung on the growths, feed utilization and survival of fingerlings of H.
ion gfulis for 8 weeks. The experiment was conducted at Michael Okpara
University of Agriculture Umudike fish farm using three tanks of (0.80in X
0.86m X 0.5511]) for three treatments. Each tank was stocked with 13
fingerlings v'eighing 90 grams each mean weight and fed with the
supplementary feed procured from African Regional Aquaculture Centre
(ARAC) Port Harcourt. Tank I was fertilized with cow dung and fed with
supplementary feed, while tank 11 was fertilized with poultry dropping also
fed with supplew ntary feed while tank III had no manure but only fed with
supplementary fcid. The tanks I and II were fertilized at the rate of 0.15kg
per m2each over a period of 8 weeks and the fish were fed two times a day
at 5% body weight. The weights of the fish were taken forth nightly (two
weeks) to evaluate the growth rate, feed utilization aiid survival. From the
results obtained, tank ii (poultry dropping) showed the highest mean growth
rate (0.08±0.02), protein efficiency ratio (0.52), specific growth rate
(1.83%) and survival rate of (98±0.0%), followed by tank 1 (0.06±0.04),
protein efficiency ratio (0.45), specific growth rate (1.68%) and mean
survival rate (82±2.0%) lastly control (0.05±0.01) Protein efficiency ratio
(0.38), specific growth rate (1.57%), and mean survival rate (51±4.0%). It
was observed that the organic manure did not degrade the phiysio-chemical
parameters (temperature, pFI, and dissolved oxygen) of water.
