| Abstract | The possibility of using cow manure for zooplankton production which may serve as feeds of seabass ( Lates calcarifer Bloch ) fry in earth ponds was investigated. The experiment was conducted in two phases. In the first phase, three different loadings of cow manure, 1, 2 and 3 kg dry weight/100 m2 /day were tested and zooplankton production monitored. The highest loading provided the highest zooplankton production without any serious water quality problem. In the second phase, 15 day old seabass fry were stocked at 120, 220 and 320 fry/ m3 in ponds loaded with 3 kg dry weight of cow manure/100 m2 /day, and two controls with 320 fry/ m3 in pond with no loading and 320 fry/ m3 in 2 m3 capacity fibre glass tank. In earth ponds; the lowest stocking density gave the best survival rate (32. 42%). A simple economic assessment of seabass fry production in a cow manure loaded pond was subsequently examined and showed that only the lowest stocking density was profitable. |
