Effect of Dietary Protein Level on Apparent Heat Increment and Post‐Prandial Nitrogen Excretion of Penaeus setiferus, P. schmitti, P. duorarum, and P. notialis Postlarvae

Abstract: The calorigenic effect of feeding (apparent heat increment, AHI) and post‐prandial nitrogen excretion (PPNE) were measured in postlarval (PL 25–30) Penaeus setiferus, P. schmitti, P. duorarum and P. notialis fed a fixed ration of 3 mg/animal using purified diets with 40, 50, 60, or 65% protein. Both AHI and PPNE increased with increasing dietary protein. The contribution of PPNE to AHI varied from 6.1 to 94%, with lesser values for P. setiferus and greater ones for P. duorarum. Also, the AHI coefficient (perce… Show more

“…This is a measurement of metabolic activity of post-absorptive processes following food ingestion (Beamish & Trippel 1990). in crustaceans depends on the quality, quantity and energetic component balance of the food (Hewitt & Irving 1990, Du-Preez et al 1992, Koshio et al 1992, Rosas et al 1996. Measured as oxygen consumption, RAHI is a response controlled by environmental factors, such as dissolved oxygen.…”

“…For RAHl estimation, the 2 rations given to the shrimp per day were considered, and it was found that at low DO levels (2 mg 1-l, 31 % air saturation), time spent on RAHl was longer (6 h at low DO levels) in contrast to time per day used by shrimp kept at high DO levels (5.8 mg 1-' DO; 90 % air saturation) (4 h). The fact that feeding produces an increased oxygen consumption rate by up to 60% in aquatic animals has been widely documented (Martinez-Palacios & Ross 1986, Du-Preez et al 1992, Rosas et al 1996. According to Beamish & Tripple (1990), this increase has been interpreted in terms of energy needs associated with AHI.…”

“…It is a measure of the metabolic work of the postabsorptive processes that continue after ingestion (Beamish and Trippel, 1990). The AHI in crustaceans depends on the quality, quantity, and the balance of energy of the components of the diet and on the environmental conditions (Hamada and Ida, 1973;Du Preez et al, 1992;Rosas et al, 1998). Thus, the AHI can be used as an index for the evaluation of the ways in which the environment modifies the processes involved in the mechanical and chemical transformations of ingested food and to give an idea of the effects on energetic metabolism (Beamish and Trippel, 1990;Rosas et al, 1998).…”
