Study of nutritional requirements and growth of penaeus merguiensis in tanks by means of purified and artificial diets ArchiMer
Cuzon, G.; Febvre, A.; Melard, J.; Parker, G.; Fagnoni, G.; Calvas, J.; Griessinger, J.m.; Hatt, P.; Poullaouec, G.; Le Bitoux, J.f.; Martin, J.l.; Michel, A..
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...

El fondo marino OceanDocs
Parker, G.; Paterlini, M.C.; Violante, R..
A synthesis is given of the present knowledge of the topographic and sediment characters of the sea floor of the Argentine Sea. After considering some general characters of passive continental margins the Argentine characteristics are described. Various 'physiographic provinces' are differentiated. The corresponding to the continental shelf is the most extensive on its several 'terraces' associated with Plio-Pleistocene sea level changes. Soft sediments are dominant,mainly being composed of sand with minor but varied quantities of shells and mud. Harder bottoms, composed of loose gravel and rocky outcrops are also present. The information presented here is not sufficient for evaluating the natural resources of the Argentine Sea or for solving sovereignty...
