Evaluation of different diets to replace Artemia nauplii for larval rearing of giant freshwater prawn (Macrobrachium rosenbergii )

A study was conducted on Macrobrachium rosenbergii larvae to evaluate the efficiency of different diets to replace Artemia nauplii in the feeding scheme. The study included two experiments performed at pilot scale in 12–L tanks using a recirculating system. Larval stocking density was 100 larvae/L. After 7 days of feeding by Artemia nauplii, different diets, included wet and dry diets and decapsulated Artemia cysts, were tested to replace Artemia nauplii. An extra treatment using only decapsulated Artemia cysts throughout the complete larval rearing was also included. The results showed that feeding larvae exclusively decapsulated cysts for the complete rearing cycle was not appropriate. | Evaluation of different diets to replace Artemia nauplii for larval rearing of giant freshwater prawn (Macrobrachium rosenbergii )
