A 56 days grow-out experiment with three protein levels (35, 40 and 45%) and three lipid levels (5, 10 and 15%) was conducted to evaluate the optimum protein and lipid ratio for Oriental River Prawn (Macrobrachium nipponense). Four hundred and five prawns, with mean (± SD) weight of 1.40 ± 0.04 g were distributed in 27 glass aquaria and were fed four times daily. Results showed that interaction...

Macrobrachium americanum is a large prawn living in rivers and coastal water bodies of tropical subtropical ecosystems the Pacific side Americas. Water temperature salinity are main physicochemical variables determining its distribution. Temperature also influences metabolic rate, which determines growth rate reproduction. Because this, preferred temperature, critical thermal maximum (CTMax), O...
