The effects of dientary prothin, lipid, and carbohydrate levels on growth and survivl of the pramn larvae were examined by the prawn larvae were fed 12 diets containing various of protein (casein;25, 35, 45, and 55%) and lipid (6.5, 11.5, and 16.5%)at a fixed carvohydrate level of 15%. In experiment2, the prawn larvae were given 9 diers containing vaious levels of protein (35, 45, and 55%) and carbohydrate (5, 15, and 25%) at a fixed lipid level of 6.5%. The effects of protein lecels on growth and survival of the pranwn varied with dietary carbohydrate levels but not with the dietary lipid leves. The elevation of lipid leves from 6.5% to 16.5% did not improve growth and survival when the diets contained suffcient leves (15% or more) of carvohydrate. Contrarily, the elevation od dietary carvohydrate lecels from 5 to 25% improved the survival of the prawn larvae when the diets xontained low levels (35%-45%) of protein. On the basis of these data, the opimum protein levels for the prawn larvae were estimated to be around 45%, 45%-55%, and 55% or more when the diets contained 25%, 155, and 5% levels of carbohydrate, resprctively.
