Yolk resorption and larval development in the brackish river prawn <scp><i>Macrobrachium macrobrachion</i></scp> under laboratory conditions: Perspectives for aquaculture

Abstract Macrobrachium macrobrachion is an African native brackish river prawn with a high commercial value. Currently, there little information on the post‐larval production of this species. Two experiments were conducted in laboratory to develop techniques for The first experiment analyzed duration yolk resorption and second described larval stages. Yolk was studied 240 newly hatched larvae 24 h based reduction area over time. For development stages, six breeding tanks containing 100 L density 50 larvae/L used. Larvae fed combination Artemia nauplii, Brachionusplicatilis , pelleted food (Larviva ProStart, Biomar Efico). results have shown that reserves varied significantly hours after hatching. At 14 hatching, each larva resorbed approximately 85% its reserve, at 18 them still had 6.1%. Twelve stages identified three critical M. are lecithotrophic need start exogenous feeding earliest latest These highlight potential mass prawns.
