Breeding sturgeon – “planting trees” with millions of dollars in the high mountains

Sturgeon farming model is always a hot industry at all times because of the luxury value it brings. Sturgeon belongs to cold-water fish, sturgeon has very high economic and nutritional value. In 2005, sturgeon was put to the test in Vietnam, growing in mountainous areas with low temperatures. In the form of raising for meat and eggs. In Vietnam, sturgeon that is focused on development is Siberian sturgeon and Chinese sturgeon.

Siberian sturgeon has the ability to live in cool places. The average size is quite large, about 2.5-3.5m and has a curved wedge-shaped snout, which is used to scour the muddy bottom for food. The body of the fish is grayish-white or black-gray in color, they have no scales and only a smooth, viscous skin.

Compared with goby fish, catfish, carp, catfish, catfish, they are more elongated and have antennae at the nose. The tail of the sturgeon is split in half and both sides have irregular fins. The appropriate temperature is at 29 degrees Celsius, in water bodies, sturgeon living in cool water does not exceed 30 degrees Celsius.

In Hue, mountainous district A Luoi has the conditions of temperature and altitude, the water source can meet the development requirements of sturgeon farming. In 2019, the Agricultural Extension Center of Thua Thien Hue province experimented with raising sturgeon in A Luoi district.

At an altitude of about 600m or more, it is very suitable for raising sturgeon because there is a natural source of clean water, flowing all year round such as streams, artificial reservoirs and natural rivers or lakes or source water from underground circuits.

As for the infrastructure for sturgeon farming, it includes: pumping system for water supply, aeration and convenient transportation system for supplying materials and consuming products.

High-performance sturgeon farming techniques

Design of ponds and tanks for sturgeon fish

The construction of the sturgeon aquarium needs to be built on a firm, high ground to be suitable for water changes. Building tanks in the shape of: rectangles, circles will be convenient for care and create a comfortable living space for fish.

Besides, sturgeon can be raised in earthen ponds or ponds with cement banks.

For raising sturgeon in earthen ponds: the pond banks need to be covered firmly, without leakage, the surface of the ponds should be at least 1.5 -m for convenient harvesting. The bottom of the sturgeon pond should be compacted.

Ensure that the water system in the tank is always at a dissolved oxygen content > 5 mg/l.

Preparing ponds and tanks for sturgeon

The sturgeon aquarium needs to be cleaned with cement and cleaned with chlorine, iodine or purple disinfectant. Ponds need to be drained, dredged with mud, repaired banks and filled all holes in the legs and banks, pond drains, cleared of pond banks, cleaned of weeds.

Next, farmers sprinkle lime with a dose depending on the appropriate pH.

For ponds with high pH, ​​it is necessary to fertilize about 5-7 kg of lime per 100m2, expose the bottom of the pond for 3-5 days for the lime to decompose all bottom waste. Finally, drain the water, soak for about 2-3 days.

For ponds with low temperature or new ponds, it is necessary to apply lime from 10-15kg/100m2, soak for 2-3 days and drain. Soak water for 1-2 times until the water in the pond has a stable pH above 6.5.

In case the pond has a neutral pH, it is necessary to get new water immediately after treatment.

How does the fish breed and release the sturgeon

Guide to choosing fingerlings

Sturgeon seed
Sturgeon seed

The quality of seed fish determines the productivity and results of the crop. High quality fingerlings are sturgeon with a size of about 50-100g/fish and a body length of about 15-20 cm, uniform, healthy and not deformed. When stocking fingerlings and water pots, they swim well, evenly dispersed, not concentrated in one place.

The process of releasing sturgeon seed

The most suitable sturgeon stocking is in March every year and the water temperature is 18-26 degrees Celsius.

Stocking density of fish in the tank: about 2-3 kg/m3.

For example pond culture, stocking density is 1.5-3 kg/m3.

When the fish is large, it is necessary to sort and divide to maintain the growth rate of the fish.

Regardless of tank culture or pond culture, the density depends on the size and amount of naturally dissolved oxygen in the water, usually 30kg/m3.

How to feed sturgeon?

Food for sturgeon

Sturgeon needs to eat food that provides adequate protein, fat, moisture, minerals and fiber.

Depending on the water temperature to feed the fish, if the water temperature is cold, feed the fish 1-2 times a day. If the water is warm, the fish should be fed about 4 times a day.

Sturgeon needs to live in a clean and oxygen-rich environment. Sturgeon likes to live at the bottom.

People need to regularly monitor and check the water environment every day to ensure good growth of fish.

Some common sturgeon diseases

  • Diseases caused by a fungus
  • Intestinal diseases caused by bacteria
  • Fish lice disease
  • Irridovirus disease

Harvesting sturgeon

Harvest mediocre fish after about 14-16 days.

When the fish reaches a size of about 1.6-2 kg/fish, it is possible to harvest or trim large fish and continue to raise small fish. Note that before harvesting sturgeon, people should stop eating fish 1-2 days before.

Pangasius, sturgeon, carp, catfish are all fish with high nutritional content.

The dishes made from sturgeon are very nutritious because of their high nutritional content and are easy to digest.
