초록

대구 치어(평균 36.5 g)의 수온 (9, 11 그리고 $13^{\circ}C$)에 따른 절식 (fasting)과 식후(post-prandial) 총암모니아성 질소 (total ammonia nitrogen, TAN) 배설의 일간 패턴과 배설률을 조사하였다. 실험어는 10일 이상 실험 수온에서 순치한 후 각 실험 수온 조건의 암모니아 배설 측정 시스템으로 옮겨 TAN 배설률을 측정하였다. 절식 TAN 배설은 72시간 절식 후 측정하였고, 식후 TAN 배설은 상품 사료(단백질 함량 40.6%)를 하루에 두 번(08:00, 16:00h), 7일간 공급한 뒤 측정하였다. 실험어 사육수조 유입수와 배출수를 2시간 간격으로 24시간 동안 채수하여 TAN을 분석하였으며, 모든 실험 조건은 3반복으로 실시하였다. 절식 및 식후 TAN 배설 모두 수온 상승에 따라 증가하였다 (p<0.05). 절식 시 시간당 평균 TAN 배설률은 수온 9, 11 그리고 $13^{\circ}C$에서 각각 9.3, 11.0 그리고 $11.9mg\;TAN\;kg\;fish^{-1}\;h^{-1}$이었고, $11^{\circ}C$$13^{\circ}C$$9^{\circ}C$에 비해 유의적으로 높았다 (p<0.05). 식후 시간당 평균 TAN 배설률의 경우 수온 9, 11 그리고 $13^{\circ}C$에서 각각 23.0, 31.6 그리고 $45.4\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$으로 나타났다. 최대 평균 TAN 배설률은 최초 사료 공급 10시간 후 나타났으며, 수온 9, 11 그리고 $13^{\circ}C$에서 각각 38.0, 52.9 그리고 $77.5\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$이였다. 수온 9, 11 그리고 $13^{\circ}C$에서 섭취한 질소에 대한 TAN 배설 비율은 각각 43.9, 46.4 그리고 48.4%로 나타나 $11^{\circ}C$$13^{\circ}C$$9^{\circ}C$에 비해 유의적으로 높았다(p<0.05). 이상의 결과에서 수온은 대구 치어의 질소 대사에 유의한 영향을 미치는 것으로 나타났다.

A study was carried out to examine the effect of water temperature on daily pattern and rate of total ammonia nitrogen (TAN) excretion in juvenile Pacific cod Gadus macrocephalus (mean body weight: $36.5{\pm}0.8\;g$) under fasting and feeding conditions. Fish were acclimated over 10 days under three different water temperatures (9, 11 and $13^{\circ}C$), and transferred to TAN measuring system under each water-temperature condition. After 72 hours of starving, fasting TAN excretion was measured at each temperature. To investigate post-prandial TAN excretion, fish were hand-fed with a commercial diet containing 40.6% crude protein for 7 days, two times daily at 08:00 and 16:00 h. Water was sampled from both the inlet and outlet of the fish chamber every 2 h over a 24-h period. Both fasting and post-prandial TAN excretion increased with increased water temperatures (p<0.05). Mean fasting TAN excretion rates at 9, 11 and $13^{\circ}C$ were 9.3, 11.0 and $11.9\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. The value of $9^{\circ}C$ was lower than those of 11 and $13^{\circ}C$ (p<0.05), but there was no significant difference between $11^{\circ}C$ and $13^{\circ}C$. Mean post-prandial TAN excretion rates at 9, 11 and $13^{\circ}C$ were 23.0, 31.6 and $45.4\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$, respectively. A peak value of post-prandial TAN excretion rate occurred after 2 h from each feeding, and the second value is always higher than the first value. Maximum post-prandial TAN excretion rate occurred after 10 h from the first feeding at $9^{\circ}C$ (mean $38.0\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), $11^{\circ}C$ ($52.9\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$) and $13^{\circ}C$ ($77.5\;mg\;TAN\;kg\;fish^{-1}\;h^{-1}$), respectively. The TAN loss for ingested nitrogen at $9^{\circ}C$ (43.9%) was lower than those of $11^{\circ}C$ (46.4%) and $13^{\circ}C$ (48.4%). The overall results indicate that water temperature exhibits a significant effect on the nitrogen excretion of juvenile Pacific cod.
