| Abstract | One of the criteria for selecting a shrimp of commercial interest in French Polynesia is the acceptability of artificial diet; such a criterion has been used to test Penaeus merguiensis.Experiments have been carried out in Centre Océanologique du Pacifique in Tahiti island where the water temperature range is 25-29°C, salinity 35 ppt, pH. 8.2, and photoperiod constant.Juveniles used in this study are hatched in CNEXO-COP at Vairao.It has been found that a 50-55% protein content diet gives a better growth performance. A carbohydrate such as starch appears more suitable than glucose or glucose plus starch in isonitrogenous purified diets.A vitamin mix rich in vitamin C, choline and inositol provides better results and a mineral mix with 3% magnesium reaches optimum. The major nutritional results for this species are applied to formulation of artificial diets.With the best diet, growth performances are normal: from 2.8 g to 9.0 g in 90 days, with about 60% survival rate at alow density, 20 animals/m² under strict control. But at another scale, in 400 m² graw-out tanks, growth was rather low even with an excellent Japanese diet containing 60% protein.Therefore, P. merguiensis does not appear to be a good candidate species for aquafarming in French Polynesia.
