Influence of Fluctuating Water Temperature and Dietary Oxytetracycline on the Safety of Monosex Nile Tilapia Oreochromis niloticus Fries.

The influence of fluctuating water temperature and dietary oxytetracycline (OTC) at 0 (0X), 80 (1X), 240 (3X), 400 (5X) and 800 mg (10X)/kg biomass/day for 30 consecutive days on the safety of monosex (all male) Nile tilapia Oreochromis niloticus fries in terms of feeding, growth, survival and histopathology of vital organs were assessed. A dose-dependent decline in feed intake and biomass was recorded. The OTC-dosed groups recorded higher mortalities than the control.

Dietary influences of oxytetracycline on the growth and serum biomarkers of Oreochromis niloticus (L.).

Tilapias are cultured globally and are rising in acceptance as the most important freshwater aquaculture species. Monitoring of serum biomarkers is a promising tool in aquaculture to screen the health status as they are virtuous indicators of extreme stress and organ dysfunction in fish. The present study examined the serum biomarkers of oxytetracycline (OTC)-dosed Nile tilapia Oreochromis niloticus at 0, 80 and 800 mg/kg biomass/day, i.
