How to raise ornamental sturgeon

Sturgeon refers to Sturgeon-shaped fish. China is one of the countries with the largest number of Sturgeon species, the widest distribution and the most abundant resources in the world. In recent years, there are more and more friends who cultivate and watch Sturgeon. The following editor will introduce how to raise Sturgeon for you.

First, how to raise ornamental Sturgeon?

Prepare a transparent, beautiful, medium-sized fish tank, expose the tap water for a day and then inject it, keep the water temperature at 13-25 ℃, and put the Sturgeon in. Feed 2-3 times a day, mainly with shrimp, red worms and seaweed, and deal with food residues regularly. In addition, Sturgeon is not tolerant to hypoxia and Sturgeon faeces are heavy and easy to sink to the bottom, so change water and clean fish tanks frequently.

Second, the living habits of wild Sturgeon

1. Sturgeon is one of the earliest living vertebrates. Sturgeon belongs to bony fishes, radiofin subclass, cartilage hard scale head order, Sturgeon-shaped order. Sturgeon is usually referred to as Sturgeon-shaped fish. It is one of the most primitive groups of fish.

two。 There are 8 species of wild Sturgeon in China, including Sturgeon Sturgeon, Dashi Sturgeon and Sakhalin Sturgeon distributed in Heilongjiang, Songhua River and Wusuli River, Chinese Sturgeon, Darkshire Sturgeon and White Sturgeon in the Yangtze River and Jinsha River, naked-bellied Sturgeon in the waters of Yining, Xinjiang, and Siberian Sturgeon in Ertix River, Brento Sea and Bosten Lake in Xinjiang. So far, China has introduced more than a dozen varieties of Russian Sturgeon, European Sturgeon, small Sturgeon, spoon Sturgeon and so on from abroad for research or artificial breeding.

3. Sturgeon is a benthic fish with a very narrow diet and a carnivorous fish. it mainly feeds on some small or slow-moving benthos in the river, followed by crustaceans and molluscs. Juvenile Chinese 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.

Due to the strict requirements of water temperature for ornamental Sturgeon, when the water temperature drops to 9-6 ℃, there will be little food intake, growth stagnation, and even weight loss. Therefore, we must pay attention to control the water temperature.
