A, pond selection
First of all, the pond should be well-watered, no water pollution, and the anniversary of the water temperature does not change much. Secondly, if you choose a semi-saline or freshwater culture, you need to choose in the more convenient water, not far away from the route, and the dust is low. Again, the bottom of the pond should not be leaking. Finally, the pond should be away from the noisy place, keep quiet, but also to ensure the convenience of transportation and communication.
Two, fish stocking
1, choose the species
In order to ensure the quality of the fish species, you should choose the authentic species of fish, robust, no disease or injury, the specification is not too different and anadromous varieties of the appropriate.
2, the transportation of fish species
Purchase a good fish species, in the process of transportation should be packed in plastic bags and oxygenated transportation, generally about 4cm of fish species each bag can be loaded with about 120 tails, the longest transport 8 hours, so the survival rate of at least 90%.
3, stocking matters
Before stocking the fish should be sterilized, and with the growth of the fish, began to catch large and keep small, the implementation of the thinning of the culture.
Three, domestication baiting
The process of breeding should be proper domestication of the puffer fish, after domestication, you can feed some minced fish meat, shrimp or snail meat, etc., and use these fresh meat as the puffer fish's openings for feed. Then domestication, let it gradually adapt to the breeding environment and bait, when they gradually adapt to the bait can be mixed into the artificial feed, and gradually increase the amount, until finally completely eat artificial feed. The bait is mainly eel material, feeding should be positioned, timing, quantity and quality, usually feeding twice a day.
Four, water quality control
1, add water to change the water
The puffer fish is a kind of fish with high requirements on the water quality, they like clear and clean water, the breeding pond should be according to the color of the water in the pond, the quality of the water, the transparency of the pond water, and the puffer fish's growth rate, feeding conditions, etc. from time to time to add new water. The pond should be filled with new water from time to time according to the color and transparency of the water, as well as the growth rate and feeding condition of the puffer fish. A big water change is needed once a month to improve the water quality.
2, water temperature control
The growth temperature of puffer fish should not be lower than 9℃, and the maximum temperature should not be higher than 32℃, so we should always pay attention to the water temperature changes in the pond, and add and cool down the temperature in time. In addition, you should also observe the change of dissolved oxygen, and inject oxygen in time if there is insufficient oxygen.
The above is about how to raise puffer fish related introduction. Farmers also need to pay special attention to the occurrence of disease in the breeding of puffer fish, regular inspection of the pond every day, if you find anomalies should be dealt with in a timely manner, to prevent and control the occurrence of unnecessary losses.
