title: [Variations in protein levels in the hemolymph, hepatopancreas and ovary of Penaeus schmitti during ovarian maturation (Crustacea, Decapoda, Peneidae)].
abstract: Variations of protein concentrations in the haemolymph, hepatopancreas and ovaries were studied during the ovarian maturation of the shrimp Penaeus schmitti. The main variations observed during this physiological process are the increase of protein and the decrease of water contents in the ovary, more pronounced at the first stages of gonadosomatic index (GSI:0-4). During ovarian maturation, water content of the ovaries and hepatopancreas decrease from 10.7 and 3.9% respectively. In relative values, protein content increases from about 40.0% in the ovary, 47.5% in the haemolymph and 15.4% in the hepatopancreas. In absolute values, the protein concentrations of the hepatopancreas showed no significant variation. In the opposite, ovary protein content is 14.7 fold higher at the end than the early stages of vitellogenesis. Relations between haemolymph, hepatopancreas and ovary with eventual transfers of protein material are discussed.
