Present study was carried out for the optimization of a non renewed medium for the production of zooplankton from pig dung. Study was carried out in plastic buckets with two treatments (T1 and T2) and one control for 27 days. Each treatment was replicated thrice. The buckets were seeded with zooplankton with an initial density of 37 individual/l (D0). Evaluation of zooplankton density in the experimental bucket was carried out on the interval of each three days up to the completion of the study. The results of the study revealed that the fishing followed with a periodical fertilization improved the zooplankton production (p ˂ 0.05) with rotifers predominance. Thus the treatment T2 media offered the best zooplanktonic average density (896 ± 977 ind.l-1) as compared to the treatment T1 (248 ± 129 ind.l-1). The adoption of this production technique of zooplankton permitted to reduced production time of this small sized live prey which could be maintained during several weeks for the aquaculture hatcheries. |
