Effects Of Water Replacement Frequency On The Growth And Survival Of Heterobranchus Iongifilis Fingerlings
ABSTRACT
The influence of frequency of water replacement on growth performance and survival of Heterobranchus Iongifihis fingerlings of mean weight 0.42g and length 3.3 cm was investigated in the laboratory over a period of sixty days. There were 5 treatments namely: Treatment A = daily water replacement, Treatment B=replacement every two days, Treatment C= replacement every three days, Treatment D =replacement every six days, Treatment E=no water replacement. Each of these treatments was replicated twice. They were fed with well balanced artificial diet at 3% body weight daily at 0800hrs and 1700 hrs. The results showed that fingerlings in treatment D performed best while those of E performed poorly. Statistical analysis showed no significant different (P>0.05) with respect to percentage weight gain and specific growth rate of fingerlings. However, there was significant difference (p<0.05) when percentage weight gain and specific growth rate were considered between treatments A and E. Generally it was observed that the less the frequency of water replacement the better the growth performance and survival rate of the fish fingerlings.
