Ammonia excretion rate of Haliotis discus hannai and effects of metabolite on water quality
摘要
Abstract
Ammonia excretion rates of Haliotis discus hannai of different sizes and the effect of its metabolites on water quality were investigated by collecting water samples at 3, 6, 9, 12, 18, and 24 h after food intake to deter-mine the changes in important water quality factors and calculate the ammonia excretion rate of each group based on TAN concentration. Experimental results showed that TAN concentration of large- and small-sized abalone groups reached the first peak at 9 h and increased with the body mass of abalone. The maximum ammonia excretion rates per unit weight of the large, medium, and small size groups were 16.79, 29.96, and 48.56 μg/(g·h), respectively. The ammonia excretion rate of the small-sized group was significantly higher than that of the medium- and large-sized groups. PO43–-P and NO2–-N concentrations of the small-, medium-, and large-sized groups reached the maximum value at 24 h, and the PO43–-P and NO2–-N concentrations of the large-sized group were significantly higher than those of the small- and medium-sized groups. NO3–-N concentration of the large-sized group reached the maximum value at 9 h, whereas NO3–-N concentration of the medium-sized group reached the maximum value at 24 h. COD concentration of the small- and medium-sized groups reached the maximum value at 18 h, whereas COD concentration of the large-sized group reached the maximum value at 24 h. Therefore, water exchange and other related processes after the food intake by the abalone H.hannai based on its ammonia excretion rate and water quality index accumulation in the water body will be somewhat referential to the promotion of the healthy growth of aquaculture organisms, reduction of disease incidence risk, and improvement of aquaculture efficiency.关键词
