The effect of water temperature on standard and routine metabolic rate in two different sizes of Nile tilapia

Balıkların metabolik oranı dolaylı olarak solunum oranları (oksijen tüketimleri) ile ölçülür. Solunum besinlerin içinde yer alan enerjinin aerobik dönüşümü için oksijen sağlar. Solunum verileri biyoenerjetik modellerin kurulmasında, belirteç olarak değişmiş çevre koşullarında ve yetiştirme ünitelerinin taşıma kapasitesinin tahmininde önemlidir. Bu çalışmada, 52.1±0.3 ve 205.4±0.5 g ağırlığındaki Nil tilapyalarının, Oreochromis niloticus, standart ve rutin metabolik oranları 19, 22, 25, 28 ve 31°C su sıcaklıklarında bilgisayara bağlı zaman ayarlı sürekli akan solunum ölçer ile belirlenmiştir. İki farklı vücut ağırlığındaki Nil tilapyalarının, su sıcaklığı ve oksijen tüketim oranı arasındaki ilişki en iyi üssel model olarak ifade edilmiştir.

Su sıcaklığının İki farklı büyüklükteki Nil tilapyalarının standart ve rutin metabolik oranına etkileri

The metabolic rate of fish is indirectly measured by their rate of respiration (oxygen consumption). Respiration provides oxygen for aerobic conversion of the energy contained in food. Respiratory data are important in the construction of bioenergetic models, indication of altered environment and estimation of carrying capacity in a rearing unit. In this study, standard and routine metabolic rates of 52.1±0.3 and 205.4±0.5 g Nile tilapia, Oreochromis niloticus, were determined with computerized intermittent flow-through respirometry at 19, 22, 25, 28 and 31°C water temperatures. The relationship between water temperature and oxygen consumption rate of Nile tilapia at two different body weights was found to best fit the exponential model.
