  1. *Donates the water temperature × number of meals interaction. **donates the partial Eta Squared (η²) for the temperature-number of meals interaction. M/d, meals/day; TDS, total dissolved salts; TAN, total ammonia nitrogen; DO, dissolved oxygen. The raw data were obtained from Hamed et al. [21]. Different letters donate statistical significance at P < 0.05
