| Cette étude doit être replacée dans une série de travaux ayant pour but de mieux connaître les caractères des protéines du milieu intérieur des crustacés. En effet, malgré plusieurs publications importantes concernant ce sujet, de nombreuses inconnues subsistent encore quant à la connaissance des protéines de l'hémolymphe, quant à leurs différences suivant le sexe des individus étudiés à l'intérieur de l'espèce considérée, quant à leurs variations, chez les femelles, en fonction des différentes phases de l'ovogenèse. Il est rendu compte ci-après des résultats obtenus après électrophorèse, en vue d'analyser les composants protéiques de l'hémolymphe du crustacé Processa edulis edulis |

| In order to improve the formulation of diets fed to reared Penaeus vannamei, the effects of soya bean and fish meals on the growth, survival, and the characteristics of the hepatopancreas and digestive enzymes of the species were studied. Four soya bean meal concentrations (0, 5, 15, 40%), four fish meal concentrations (0, 5, 15, 30%), two forms of soya bean meal and three fish meals of different geographical origin were tested. Experimental conditions were as follows: ten individuals were placed in each tank (0.5 m2 ) and two tanks were subjected to each treatment. Food was given twice a day (08-09.00 h and 19.00 h) at 10% of the initial weight each day. For biochemical analyses, nine individuals per treatment were used for the determination of the... |

| Morphological differences associated with sex or stage, together with total lipids and carotenoids, were studied in Euphausia superba as possible indicators of physiological condition. E. superba displays sexual dimorphism during growth. A group of mature males, called Males II herein, has a greater abdominal length, suggesting that they are faster swimmers, a feature implying higher metabolic rates and a higher demand for protecting pigments like carotenoids. Mature Males II have proportionally lower lipids but higher total lipid-soluble carotenoids, a counterintuitive finding. Males II also have bigger eyes. Significant regressions with carotenoids were found for wet weight, abdominal length, and eye diameter. On a spatial analysis, population... |
