Behavioral, physiological, encephalopathological alterations and endoplasmic reticulum stress/apoptotic-related gene transcription in reaction to heat stress in Oreochromis niloticus fish: impact of dietary supplements with Spirulina-Coenzyme Q10 nanoemulsion.

ABSTRACT: Water temperature significantly influences fish behavior and physiology. Thus, the current study assessed the effects of dietary incorporation of Spirulina-co-enzyme Q10 nanoemulsion (SCN) on various health parameters in Nile tilapia (Oreochromis niloticus) raised in heat stress conditions (32 °C) for 60 days. In a completely randomized design, Nile tilapia (n = 225) were divided into 5 groups (3 replicates, 15 fish per group). The first (C25) and second (SCN0) groups were fed a basal diet and reared at 25 °C and 32 °C, respectively. Groups 3-5 were reared at 32 °C and fed a diet supplemented with SCN at 10 mg/kg (SCN10), 20 mg/kg (SCN20), and 40 mg/kg (SCN40), respectively. The findings indicated that the inclusion of SCN in the diets of O. niloticus, particularly at 20 and 40 mg/ kg conc
