The objective of this work was to verify the occurrence of compensatory growth in Malaysian prawn (Macrobrachium rosenbergii) reared in pens, after being stocked in cages under high densities during nursery phase. The experiment was carried out in 0.5 m2 cages and 2-m2 pens set in natural bottom pond with 2,400 m2. Prawn post-larvae (PL) with an average weight of 0.026 ± 0.012 g (nursery phase) were initially stocked in 16 cages at the densities of 50, 400, 800 and […]

The feeding is one of the most important factors to larval development and the sucess of the commercial cultivation of decapod crustacean larvae depends on the efficient and economic utilization of the available food. The performance of Macrobrachium rosenbergii larva submitted to four different feeding systems was tested by using the daily observation of the larval substages and the first metamorphoses. The larvae were stocked in a density of approximately 100 larvas.l-1, in 16 tanks, with 33 liters capacity. The […]

This work was carried out to identify the replacement of the nauplii Artemia sp. for the enriched and frozen rotifer (Brachionus plicatilis O.F. Müller, 1786) on the larval development and survival of the freshwater prawn M. rosenbergii. The experiment was developed according to the following treatments: 100% B. plicatilis (30 rots/ mL) (T1); 100% Artemia sp. (5 nas/ mL) (T2), 60% Artemia sp. (3 nas/ mL) + 40% B. plicatilis (12 rots/ mL) (T3) e 40% Artemia sp. (2 nas/ […]
