Abstract
This study aims to evaluate the effect of feeding feed containing red ginger extract on the immunity and survival of catfish (Clarias gariepinus) fingerlings exposed to high temperature conditions. The research was carried out experimentally with a Completely Randomized Design (CRD) consisting of four treatment doses of red ginger extract (A: 0 ml/kg, B: 30 ml/kg, C: 40 ml/kg, D: 50 ml/kg) and three replications. Parameters observed included survival rate, white blood cell count, red blood cell count. The results showed that the addition of red ginger extract to feed was able to increase catfish survival by up to 90% at a dose of 50 ml/kg. A significant increase in the number of white blood cells and red blood cells in fish given red ginger extract indicates a better immune response. Red ginger extract has proven effective in helping fish adapt to thermal stress by increasing immunity and resistance to high water temperatures.
