Tilapia is a freshwater fish that is now selling well. It is also very simple in the usual breeding. As long as the fish feed pellets feeding regularly and quantitatively every day, change the water in time. The fish feed machine is the main equipment to make fish feed pellets. This article will introduce how to raise tilapia in detail.
Basic Conditions Of The Pond
Choose a place with good water source, freshwater, no industrial pollution, good soil quality, and convenient transportation. The bottom of the pool is flat, the pond base is strong, the water retention performance is good, and there is no high damper in the surrounding air. After nuisance treatment, it should be properly placed at the appropriate time.
The Selection Of Pond Fish Farming
1. The choice of fish. Choose childhood tilapia with a smooth surface, no damage, good health, full-body, neat specifications, high male rate, size of about 5 cm. After 5% salt solution or 5-10 mg/L potassium permanganate solution dipping, put it in the fish pond. 2. Stocking density. After the pond water has been tested to be non-toxic, the tilapia fry is placed on the principle of 1 tail/m³ of water. The pond of the main tilapia can increase the income of the breeding by matching other fish. In addition to herring, and grass carp, such as carp and catfish can also be properly mixed.
Feeding management Of Tilapia
1. Equipped with aeration facilities. In order to ensure high-density culture conditions, the cultured tilapia does not appear to float. Ensure high yield and stability. 2. Feeding. In the process of breeding, in order to save costs, also in line with the principle of pollution-free. Before the tilapia reaches 150g, the use of fertilizer water culture, relying on animal manure fertilizer ponds to cultivate biological feed fish. In general, fertilize once a week. After 2 to 3 months, when the tilapia raised reaches the specification of 250 g/tail. It enters the medium-term breeding, changes the breeding method, and puts the tilapia feed culture. At this time, many farmers are feeding the fish feed pellets. As long as the fish can feed, on the principle of not wasting the feed, how much the fish can feed, the tilapia grows faster, about 7-8 months can be raised to 1 kg/tail or more. In the middle and late stages. It is necessary to keep the water fresh and ensure that the fish have a good appetite to achieve rapid growth. 3. Choose a good feed. Scientific feeding, when selected fish feed pellets, fishermen should choose regular manufacturers to produce quality-assured feed. Fish feed pellets can be made using a fish feed extruder if conditions permit. A small amount of meals helps to promote the digestion and absorption of fish, and 70% of the fish feed pellets are fed during the highest oxygen in the pond during the day. Which is beneficial to digestion and absorption, increase feed conversion rate and reduce feed cost.
Water Quality Management
Maintaining good water quality can stimulate the appetite of tilapia, reduce the feed coefficient, and increase the growth rate of fish. In the early stage of breeding, in order to save costs, the use of fertilizer and water culture. However, in the medium term, it is necessary to add new water at the right time to adjust the water quality. Changing the water regularly, adding new water, and mechanical oxygenation are important means to regulate water quality. Therefore, every 3 to 4 days, freshwater should be added to the pond, 20 to 30 cm each time. When the water quality deteriorates, you should change the water quickly. First, drain the pond water by 1/3 to 1/2, then add new water until the water quality is good. Tilapia is a tropical fish native to Africa and one of the world's cultured species. Tilapia is one of the fine breeds recommended by the Food and Agriculture Organization of the United Nations. Which has the advantages of miscellaneous food, fast growth, strong adaptability, low disease, high population yield, and good meat quality. The good market prospects of tilapia are the main aquaculture species in current aquaculture, especially in freshwater aquaculture.
Choosing a suitable fish feed machine and using it properly will significantly improve the quality of the feed. It will soon reflect a benign effect in the production process. If you can further master the technology of making fish feed pellets, you can also greatly reduce the cost of materials, thereby increasing profits. Zhengzhou Fusmar Machinery specializes in the production of fish feed machine, animal feed machine, wood pellet machine, charcoal briquette machine, and other machinery.
