How should sturgeon be farmed? A guide to raising the "King of Fish of the Yangtze" well
Sturgeon live in the Yangtze River basin. They are very large and very heavy, and are the largest fish in the Yangtze River basin, which is why people call them the 'King of Fish of the Yangtze'. They are also the oldest surviving vertebrates. There are many species of sturgeon, and they differ from region to region, with names such as Chinese sturgeon, kaluga sturgeon, and kulazii. Our country has the most sturgeon species and the widest distribution. The wild Chinese sturgeon is a national first-class protected animal, and hunting it is illegal. However, we can buy farmed ones. Market demand is large, and market prices are high. Below, the Tuliu.com editor will tell everyone about sturgeon farming methods~
1. Preparing the farming site
1. Sturgeon is a fish species that very much likes to grow in warm water, so it has relatively high requirements for water quality. We must make sufficient preparations before farming. Sturgeon are relatively large, so the farming site area must be no less than 5 mu, with the most suitable range being between 6 mu and 9 mu.
2. The water in the farming pond must also be deep enough, and the water in the pond must not be polluted and must stay clean. The traffic conditions around the farming site should also be as convenient as possible, to prevent unnecessary trouble in future management.
3. Then clean the environment thoroughly. Disinfect the pond. Lime and so on can be used.
4. Before farming, we can pour some livestock manure or chicken manure into the farming pond, so that enough plankton can be cultivated in the pond water. When the fry are stocked, the fish can forage on their own inside, which can increase their ability to adapt to the new environment.
2. Selection and stocking of fry
1. Fry determine the quantity and quality from then on, so when choosing fry, do not seek small bargains. Keep your eyes open and choose sturgeon fry that look very healthy and disease-free. Observe their mental state. The fry chosen must first have intact scales and fins, and those that swim in the water looking relatively lively and full of energy can be chosen. Choose ones with a high survival rate and that can also reproduce offspring.
2. Before releasing the fry into the pond, remember to first release about 10 for a trial. This can reduce losses in case of any accident. After 2 days, observe whether the fry are growing abnormally. If deaths occur or they look lifeless, then it means the pond water is not suitable for sturgeon survival. At this time, the pond water must be replaced. If everything is normal after observation by the same method, then you can farm with confidence.
3. Sturgeon feeding management
1. For better feeding, we can appropriately add some salt to the pond. Stop at the right amount and do not overdo it. Otherwise, sturgeon will be unable to adapt and will stop eating. During feeding, the feeding amount must also be reasonably controlled. Sturgeon do not know what fullness is when eating. If we feed too much at one time, they may eat themselves to death, so be sure to feed small amounts more often.
2. Because sturgeon have relatively high requirements for the water quality they live in, newly bought fry need the water changed once a day. After they adapt to the surrounding environment, it can be changed once every 7 days, and once the sturgeon reach adulthood, changing it once every 15 days is enough. In daily management, to prevent the water quality in the farming pond from quickly deteriorating, the feed residue in the water after feeding must be promptly removed.
Alright, the above is the sturgeon farming method brought to you by the Tuliu.com editor. We hope it helps everyone. See you next time
