Tilapia culture management

Tilapia is a tropical fish, originally living in Africa, in recent years has become the main culture of freshwater fish, culture management is an important work, mainly summer management and winter management, these are two critical periods, because of weather changes and some problems, we need to pay attention to what should be done, the editor will introduce below.

1. Environmental requirements

Need to keep the aquaculture water clean and clear all the time, can not change water for a long time, must change water regularly, actually observe the clarity of water, if there is turbidity, you should change water, preferably live water culture, so that the change of water will not be affected. When there is no oxygen in the water, the fish will float their head or breathe close to the shore. Be sure to be equipped with oxygen equipment to increase the oxygen in the water from time to time. The residue of the food fed daily in the water should be salvaged, otherwise the water is easy to be polluted, easy to breed bacteria and cause diseases.

2. Feeding

If you simply feed, the cost is relatively high, so before releasing fish fry, you can apply fertilizer and use some mature fermented livestock manure, which can improve the water quality, breed some small organisms in the water and provide underwater feed for fish. Sometimes you can feed meat from snail lions and clam shells to fish. Generally do not feed more than twice a day, and generally feed until the fish are no longer eating, so that the fish grow very fast.

3. Summer

Fertilizing water quality in summer should mainly use biological fertilizer, at this time you can apply more fertilizer, the best water color is tea-brown, but still have 30 centimeters of visible transparency, can not see nothing, probably require about 200 jin per mu of fertilizer, use in accordance with the requirements. It is necessary to strengthen ponds and some protective facilities, such as blocking, to prevent summer floods from entering and destroying facilities. At this time is the fastest growing period, to increase feed, to pay attention to the proportion of feed nutrition, more feed containing more protein.

4. Winter

The main purpose is to control the temperature. if the water temperature is not lower than 15 degrees, the fish will not grow and begin to dormancy, so it is necessary to provide artificial heat preservation, generally can add water, and the temperature below the water depth can be maintained, preferably in a greenhouse. Can create a warm environment. The water temperature has increased a lot. At this time, we should pay attention to less fertilization, decomposition is relatively slow, plant more, algae can prevent fish from lack of oxygen. Feed to maintain normal, can keep warm to maintain weight.

Tilapia is a kind of tropical fish, in culture management, winter is a critical period, overwintering growth is slow, some do not grow. Some die easily. The most important thing is to keep the water warm and keep feeding. Survive the winter smoothly.
