Illustration chez Austropotamobius pallipes pallipes Le. des effets d'un facteur trophique : le taux des proteines de la ration
Observations on the effects of dietary protein levels on several physiological parameters of the crayfish Austropotamobius pallipes pallipes Le.
Laboratoire d'Ecologie et Biologie générale, U.E.R. des Sciences, 123, rue Albert-Thomas, 87100 Limoges
L'écrevisse pallipède recevant la ration alimentaire la plus riche en protéines se trouve dans des conditions plus favorables, particulièrement pour la population originaire des eaux eutrophes. La traduction, parmi les tests physiologiques, est une augmentation de la fréquence des mues, du niveau des protéines de l'hémolymphe et du pourcentage de la masse musculaire abdominale.
La relation positive entre niveau des protéines de l'hémolymphe et pourcentage de chair comestible montre que la protéinémie est un bon "indice" physiologique.
Abstract
The crayfish fed the highest level of protein were in the best condition. Each increase in protein resulted in a better condition of the crayfish, especially for the "eutrophic-water" population. The effect is to increase noulting frequency, haemolymph protein content and percent edible meat.
The positive relation between the protein concentrations in the haemolymph and the rate of meat production that the former are a good physiological indicator.
