The requirement of prawn for sterols was examined by the feeding trials using the artificial diet devised by authors. The prawn receiving the diet supplemented with cholesterol grew normally, and the survival rate and growth rate were 86-95% and 56-98%, respectively. However, the growth rate of prawn receiving the sterol-free diet was poor (22-64%). The requirement for sterols of the prawn determined by 30- or 40-day feeding trials was about 0.5g per 100g of diet, under the experimental conditions used. The survival rates of prawn fed the diet containing ergosterol, stigmasterol and β-sitosterol revealed a similar percentage to that of prawn fed the cholesterol-diet, but, the growth rates of these sterols were inferior to cholesterol. From these results, it was suggested that the prawn requires the dietary sterol for normal growth similarly to insects.
