Abstract

The secondary stress response of Nile tiiapia, Oreochromis niloticus after direct transfer to saline water was evaluated assessing the levels of hematocrit, plasma glucose, sodium, potassium, chloride and calcium. Fish were transferred directly from freshwater to two experimental salinity (9 and 18 ppt) for 72 hours. Plasma glucose, $Na^+, K^+, Cl^- and Ca^{++}$ all increased however, hematocrit did not change throughout the 3 days exposure period. Considering the parameters measured in this study Nile tiiapia appeared to exhibit a stress response to direct transfer to saline water, nevertheless, the magnitude of stress response was related to salinity level.

Özet

Tilapianın, Oreochromis niloticus tuzlu suya direkt olarak transfer edilmesi durumunda gelişen sekonder stres yanıtı hematokrit, plazma glukoz, sodyum, potasyum, klorid ve kalsiyum ölçümleri ile değerlendirilmiştir. Balıklar doğrudan iki farklı deneysel tuzluluğa (9 ve 18 ppt) 72 saatlik bir periyotta maruz bırakılmışlardır. İncelenen parametrelerden plazma glukoz, plazma $Na^+, K^+, Cl^- ve Ca^{++}$ deney süresince artış gösterirken hematokrit değerleri değişmemiştir. Bu çalışmada değerlendirilen parametreler gözönüne alındığında tilapianın tuzlu suya direkt transferinin strese neden olduğu, ancak stres yanıtının büyüklüğünün tululuk seviyesi ile ilgili olduğu belirlenmiştir
