Abstract

The study aims at determining the dynamics of dissolved oxygen in relation to pH and survival of fish culture in fibre glass tank. Three feeds were used. They are dried chicken manure only (Treatment I), mixture of dried chicken manure with commercial diet (coppens) (Treatment II) and commercial diet only (coppens only) (Treatment III). The physicochemical characteristics of water for the treatments (T1, TII and TIII) in fibre glass tank were determined twice a month using standard methods. ANOVA was used to analyze the effects of the rate of changes between dissolved oxygen, pH and the fish survival. The result from this study showed that the fish in treatment III had the highest weight gain of 272.10g followed by treatment II (172.07g) and 3 (143.47g) (P<0.05). There was no significance difference at probability level 0f (P<0.05) in survival rate. Variation exists in the water quality parameters examined, dissolved oxygen and pH falls within the range for fish survival. pH was correlated with dissolved oxygen. The findings also provide the useful information about the conditions of the three treatment which will ultimately help to manage the water body for sustainable production. The model showed that dissolved oxygen depends on pH.
