Present study aimed at the comparison of two production techniques of the zooplankton mass production (renewed and non-renewed medium) so as to determine the most efficient. In fact, the experimentation was realized in triplicate in plastic buckets, grouped together in three treatments (T1, T2 and T3) which were fertilized and a control (T0) during 27 days. The buckets were seeded in zooplankton with an initial density of 37individu.l-1 (D0). From D12, those of T2 and T3 were periodically fertilized and have respectively sustained a partial and periodical renewal and fishing (50%) in the production medium. The results have shown that the optimization in non-renewed medium has given the best zooplankton production (p ˂ 0.05). Thus, the mean zooplankton density was higher in treatment T3 (896 ± 977 ind.l-1) as compared to T2 (631± 440 ind.l-1) where the medium was renewed. The best technique is the one made in the non-renewed medium as it also favored a continuous zooplankton production for a long period whereas the production in renewed medium is discontinuous and for a short duration. The adoption of this technique permitted to high densities of small sized live prey (rotifers) for several weeks, for the aquaculture hatcheries.
