According to the growth stage of groupers, feeding conditions play a crucial role in determining the amount of food provided. It is important to feed them in measured portions, with smaller meals more frequently, ensuring that the fish have enough time to consume the food before it sinks. The main diet for groupers consists of fresh fish. During the first two months of the breeding season, minced small fish are fed at approximately 10% of their body weight. In the last three months, the fish are cut into chunks and fed at 5% of their body weight. One month prior to harvest, feeding is reduced to about 3% of their body weight. In addition to fresh fish, artificial diets with a protein content of over 40% can also be used. These should be processed into different sizes depending on the fry's size and feeding conditions.
When feeding, it’s best to use a controlled, multiple-meal approach. Start by feeding in the center of the pond, then gradually move outward. Each feeding session should be divided into several portions so that the fish can eat the food before it settles on the bottom. The ideal feeding times are between 5 to 6 AM in the morning and 7 to 8 PM in the evening.
Throughout the breeding period, it’s essential to regularly monitor water temperature, salinity, and pH levels in the pond. Water changes should be made according to the quality of the pond to maintain a healthy environment. Additionally, the lake or pond should be inspected regularly to ensure the dam, gates, and screens are secure. Any necessary repairs or reinforcements must be carried out promptly to prevent fish escapes and maintain overall safety.
