Assessment of effect of fish feeding practices on the water quality of some fish ponds in Ekiti State Fish Farm, Ado Ekiti, Nigeria

Abstract

The present study was aimed to access the effect of fish feeding practices on the water quality of some fish ponds in Ekiti State Fish Farm, Ado Ekiti, Nigeria. Water samples for physico-chemical parameters were collect fortnightly, from the selected ponds and reservoir for a period of six month. Proximate composition of the fish diets (Coppens, Vital and CHI) used were also carried out using standard methods. Proximate analyzed showed that CHI feed had the lowest lipid and crude protein content, the highest crude protein and lipid content was recorded for Coppens feed. Pond 2 was found to have the mean lowest dissolved oxygen content while pH total alkalinity and acidity, conductivity, TOC, OM, BOD, Ca2+, Mg2+, NO3- and SO42 contents were significantly higher (p< 0.05) in pond 2 than other stations. The study concluded that feed quality and feeding frequency negatively impacted the water quality of the fish ponds.
