Seasonal water parameters of active and resting nursery ponds on Wildlife and Fisheries Management Department's farm University of Ibadan

Abstract

Water quality parameters from active and resting nursery ponds were taken in both dry and wet seasons at the model fish farms, University of Ibadan. Temperature, turbidity, dissolved oxygen (D.O.), free carbon dioxide, pH, total alkalinity, total hardness and nitrite were examined to determine the suitable conditions of the ponds and seasons for optimum fish production. The physico-chemical parameters of all the ponds sampled for the two seasons (dry and wet) were interrelated with slight differences in their concentrations, levels and readings. From the data generated all the parameters were within the desirable standard for fish culture in all the ponds within the seasons. However, the quality of water in the active nursery pond was significantly better (p<0.005) than the resting nursery pond in both wet and fry seasons.
