What feed does carnivorous fish Sturgeon eat to grow up? How much feed does it take to grow one jin? How much is it per ton?

Sturgeon is a kind of vertebrate which originated earlier in our country, and it is a carnivore, so the food eaten is relatively narrow, but if it is farmed, it can be fed with related feed, what kind of feed does Sturgeon eat to grow up? How much feed does it take to grow one jin? How much is it per ton?

Sturgeon feed price:

The price of Sturgeon feed depends on the quality. Generally, the growth rate is about 8000 yuan / ton, and the growth rate is related to the specification.

In addition to feed, Sturgeon also eat other foods:

1. Sturgeon is a benthic fish with a very narrow diet and a carnivorous fish. it mainly feeds on some small or slow-moving benthos, followed by crustaceans and molluscs. The juvenile Sturgeon in the estuary mainly feed on benthic fish, such as Kun and pupa, krill and clam, etc., and generally stop eating during the spawning period.

2. Sturgeon is an animal-eating fish, which can prey on zooplankton during the feeding stage of juvenile fish, but the fry soon develop into benthic life. In line with this way of life, the mouth of the Sturgeon is prominent and inferior. The food preferred by Sturgeon varies with different species, and the main foods are water earthworms, crustaceans, molluscs and small fish. Sturgeon fry can be fed with artificial compound feed directly after feeding. In actual production, live bait is often used to feed Sturgeon fry.

3. Under the condition of artificial culture, Sturgeon larvae begin to feed at a total length of 3.05 ±0.07 cm, which mainly feeds on aquatic oligopods, chironomid larvae, Cladocera and copepods, and young Sturgeons feed mainly on aquatic oligohairs (water worms, trematodes, tail Gill worms, etc.), Cladocera (Daphnia Magna, Daphnia carinata, etc.), aquatic insect larvae (Chironomus larvae) and shrimp Adult Sturgeon mainly eats all kinds of feed fish pieces (such as crucian carp, tilapia, silver carp and grass carp, etc.).

Feed selection:

1. Main raw materials: the main raw materials of Sturgeon are imported fish meal, expanded soybean, yeast, imported fish oil, flour, stable vitamins, organic chelating minerals and so on. When these raw materials come into the factory, they are all qualified by the chemist before they are unloaded. If you fail, you will be rejected.

2. The characteristics of Sturgeon feed: when we choose Sturgeon feed, we must choose the optimal formula design, with comprehensive and balanced nutrition, good palatability, strong food attraction, excellent performance-to-price ratio and low feed coefficient, which can meet the needs of rapid growth of Sturgeon. Also choose not to add false protein ingredients, do not contain any illegal drugs, avoid polluting the culture environment and ensure the healthy growth of fish. In order to improve the disease resistance of fish, we should also choose the feed with immunity enhancer to promote the rapid absorption of nutrients and strengthen the physique. Only by choosing these fish can your fish grow healthily.

3, nutritional indicators: Sturgeon feed can be divided into three stages to feed, according to the size of Sturgeon to choose the corresponding size of feed, if the choice is too large or too small is not conducive to the growth requirements of fish. Feed is divided into three stages: Sturgeon juvenile, Sturgeon growth, Sturgeon fattening. Juvenile Sturgeon is suitable for juvenile stage, with crude protein greater than or equal to 42%, crude fiber less than or equal to 8%, crude ash less than or equal to 16%, calcium content 0.5-1.5, phosphorus content 0.8-1.5, salt content 0.5-2.0, moisture less than or equal to 12%, lysine greater than or equal to 2.5%.

Meet these suitable for the healthy growth of young Sturgeon. Sturgeon growth is suitable for the adult stage, the crude protein is 2% less than the juvenile stage, and the lysine is 0.5% less than the juvenile stage. Other indices are the same. Sturgeon fattening is suitable for the adult stage, the crude protein is 2% less than the Sturgeon growth stage, and the lysine is 0.2% less than the Sturgeon growth stage. Other indices are the same. As long as the feed meets these nutritional indicators, choose the species you need according to the appropriate stage of your fish.
