GROWTH PERFORMANCE OF TILAPIA (Oreochromis niloticus) THAT INFECTED Aeromonas hydrophyla BACTERIA WITH ADDITION OF NUTRITION IN FEED

Tilapia (Oreochromis niloticus) is one of the important economically valuable freshwater fish commodities. However, in the cultivation of tilapia, the emergence of disease is one of the problems that affect the quality and quantity of aquaculture production. One of the diseases that often arises is Aeromonas hydrophylla infection. These problems are expected to be overcome by providing vitamin C in fish feed. This study aims to look at the growth performance of tilapia infected with Aeromonas hydrophylla bacteria by measuring length, weight gain, survival rate, feed conversion ratio, and water quality parameters such as temperature, pH, and DO (Dissolved Oxygen).
