There are 100 loaches per square meter-150 loaches. 30 snakeheads per square meter.
When the fish was young, the water depth was 30CM. As the fish grow up, the water level can be gradually deepened, and the deepest water level is 60CM.
The area of ecological floating bed accounts for 15% of the total area of fish ponds. Planting some aquatic plants such as water spinach can improve water quality! In order to prevent fish from eating roots, a net can be added under the floating bed.
The water quality of fish ponds will deteriorate after a long time of cultivation, and new water needs to be replaced. Tap water cannot be directly injected into the fish pond, but can be put in a bucket for one day and then poured into the fish pond. Before adding new water, drain the bottom sewage and pump it dry with a small pump. It is enough to add new sewage every time, accounting for about 10%- 15% of the total water in the fish pond, so as not to cause too much change in the water environment and affect the normal growth of fish! It is usually good to do it once every 3 or 4 days, at least once a week.
Feeding fish is better than being hungry! Feed only 1%- 1.2% of the fish's weight every day. Feeding too many fish is easy to get sick. The total amount of a day is set and can be fed two or three times.
