Abstract
- Endogenous ammonia excretion rate and exogenous ammonia excretion rate of red sea bream (Pagrus major) were investigated under the combination of four different temperature regimes (10, 15, 20 and 25℃) and two different densities (5.5 and 11 kg m-3). Ammonia excretion was significantly increased with increasing temperature and density. Endogenous ammonia excretions of red sea bream with lower density under 10, 15, 20 and 25℃ were ranged 88.76∼143.26 mg kg-1 d-1, while that under higher density were ranged 105.24∼168.82 mg kg-1 d-1. The relationship between endogenous ammonia excretion rate and temperature in low density was Y=18.746X+67.66 (R2=0.9865) and that in high density was Y=21.306X+80.416 (R2=0.9804). Exogenous ammonia excretions of red sea bream with low density under 10, 15, 20 and 25℃ were ranged 343.48∼601.74 mg kg-1 d-1. On other hand, exogenous ammonia excretion rates in high density were ranged 391.92∼683.40 mg kg-1 d-1. Ration of ammonia excretion to ingested nitrogen of red sea bream with lower density under 10, 15, 20 and 25℃ were ranged 27.92∼50.11%, while that in higher density were ranged 31.65∼56.89%. The relationship between exogenous ammonia excretion (Y) and temperature (T) in low density was Y=90.68T+244.47 (R2=0.9772) and that in high density was Y=100.66T+290.09 (R2=0.9880)
