Expert Answer
Yellow croaker fish primarily eat animal-based food in the wild, but their diet changes at different growth stages.
In their juvenile stage, yellow croaker fish feed on plankton, while in adulthood, they consume small fish, shrimp, snails, clams, and other similar foods. Some large yellow croaker fish may even eat the eggs of carp, crucian carp, and other fish.
In addition to these, yellow croaker fish also eat some aquatic plants, such as duckweed, moss, and algae.
Yellow Croaker Fish Farming Methods
- Water Temperature: Yellow croaker, also known as yellow catfish, is a common freshwater fish found in a wide range of habitats. They prefer to grow in warm environments, so when farming them, the water temperature should be maintained between 25-28°C for optimal growth.
- Water Quality: Yellow croaker fish prefer clean and fresh water. The water transparency should be at least 35 centimeters, and the water should remain clean and clear. They thrive in slightly alkaline water, with the water’s pH value best maintained between 7.0 and 8.5. When farming in a fish pond, water should be changed once a month; in warmer temperatures, it may be necessary to change the water every two weeks.
