Growth Respose, Feed Utilization And Survival Of Fingerlings Of Heterobranclius Longilis 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. longilis for 8 weeks. The experiment was conducted at
Michael Okpara University of Agriculture Umudike fish farm using three tanks of
(0.80in X 0.8Gm X 0.55m) for three treatments. Each tank was stocked with 13
fingerlings weighing 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 supply tnta1y feed while
tank III had no manure bitt only fed with supplementary feed. The tanks I and
II were fertilized at the rate of 0.15kg per rn2each 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 and 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 lank 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±0.0 1) 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
physio-chemical parameters (temperature, p1-I, and dissolved oxygen) of water.
