Study of nitrogen excretion in the gilthead seabream (Sparus aurata L.): influence of nutritional state



Study of nitrogen excretion in the gilthead seabream (Sparus aurata L.): influence of nutritional state



Comparative Biochemistry and Physiology A, Comparative Physiology 105(1): 17-19



1. Ammonia nitrogen excretion was measured at various time intervals (24 and 48 hr) in fed and previously fasted gilthead seabream (Sparus aurata, L.). 2. Postprandial excretion was biphasic, with maximum peaks occurring after 2 and 6-8 hr. 3. In fasted fish, the excretion rate decreased significantly, showing a very similar profile to postprandial excretion, which suggests the existence of a biological rhythm in ammonia excretion.
