The present study was designed to test the effects of type of binder on growth, nutritional physiology, total apparent digestibility, and some elements of the energetic balance of early O. maya juveniles. Two experiments were performed. One was aimed at evaluating the effect of type of binder on growth, nutritional physiology, and energetic balance and the other at knowing the effect of the binder on total apparent digestibility of O. maya. Binder type affected growth and survival of early O. maya juveniles. Octopuses fed alginate-bound crab meat lost weight and died, revealing that this type of binder limits nutrient absorption from the diet. In contrast, when gelatin was used as binder, energetic balance was similar to that obtained in animals fed...

Effect of dietary protein level on growth and energy utilization by Litopenaeus stylirostris under laboratory conditions
Provedor de dados: 5
Autores: Gauquelin, F; Cuzon, Gerard; Gaxiola, G; Rosas, C; Arena, L; Bureau, D; Cochard, Jean-claude.
A study was conducted using a bioenergetics approach to generate information on energy requirement and feed utilization of Litopenaeus stylirostris. Animals (initial mean weight 21 +/- 1 g were fed ad libitum six experimental diets, ranging from 25 to 58% crude protein (CP), for 50 days.   Weight gain increased from 21 to 30 g with increasing dietary protein level. Survival rates averaged 80%. Basal metabolism (HeE) and heat increment of feeding (HiE) were monitored using respirometry. HeE was on average I U shrimp(-1) day(-1) or 47 U kg live weight(-1) day (22 kJ/kg(0.8). d(-1)), slightly more than what is observed in fish. HiE averaged 0.2 W/sbrimp(-1) day(-1) or 10 W kg live weight(-1) day(-1) (4 kJ/kg(0.8) d(-1)). It represented 3 1 % and 12%...
