Embodiment 1

[0028] The large-scale cultivation method of dragon stripes in greenhouse improves the efficiency of greenhouse cultivation of dragon stripes and realizes large-scale cultivation by strengthening the purification of breeding water and optimizing the types and methods of feed feeding at different growth stages.

[0029] 1. The design method of the greenhouse is as follows: the greenhouse is 50m long and 25m wide, divided into 5 small fish ponds, the water depth in the pond is 1.3m; the fish pond is connected with the biological filter through the sedimentation tank, the sedimentation pond is 15m long, 8m wide, and the slope is 2%. The flow of fish pond water into the sedimentation tank is 250m 3 / h; the biological filter is a circular pool with a diameter of 3m, the filter material is vermiculite, and the particle size of the filter material is 30mm; the thickness of the filter material is 1.2m, and the thickness of the working layer is 0.8m; the aquaculture water is treated by t...

Embodiment 2

[0043] The large-scale cultivation method of dragon stripes in greenhouse improves the efficiency of greenhouse cultivation of dragon stripes and realizes large-scale cultivation by strengthening the purification of breeding water and optimizing the types and methods of feed feeding at different growth stages.

[0044] 1. The design method of the greenhouse is as follows: the greenhouse is 50m long and 25m wide, and is divided into 5 small fish ponds with a water depth of 1.3m; the fish ponds are connected to the biological filter through the sedimentation tank, and the sedimentation pond is 15m long and 8m wide with a slope of 3%.

Abstract

The invention provides a large-scale breeding method for dragon-spotted greenhouses, which belongs to the field of aquaculture, and realizes large-scale cultivation by strengthening the purification of breeding water bodies and optimizing the types and methods of feed feeding at different growth stages; wherein, the design of the greenhouse adopts fish ponds connected with biological filters, It is convenient to purify the breeding water; when the dragon pattern grows to a certain stage, the artificial feed is used for domestication. The artificial feed is a microcapsule structure, including the feed core material and the wall material; the wall material is made of maltodextrin, propolis, peach gum, Made of trehalose, hawthorn powder, glycerin and distilled water. The design of the greenhouse of the present invention adopts a fish pond connected with a biological filter to improve the purification efficiency of aquaculture water while saving costs; the artificial feed adopts a microcapsule structure, which has high utilization rate and good digestion and absorption, and can promote the rapid growth of dragon stripes and realize high-efficiency scale farming.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for large-scale cultivation of dragon stripes in a greenhouse. Background technique [0002] Australian dragon spot, also known as Murray cod, river cod, Oriental cod, cod perch, Australian freshwater cod, etc., China is called Australian dragon spot, worm grain wheat cod perch or worm pattern grouper, it is native to Australia. A famous freshwater economic fish in the Ruihe River Basin. This fish is a white-fleshed fish, which ranks first among the four major economic fish in Australia and is one of the largest freshwater fish in the world. Because of its special shape and delicious taste, the Australian dragon stripe is known as the "National Treasure Fish" in Australia. Because of its tender and delicious meat, thick, few thorns, and rich in 4 kinds of amino acids and EPA and DHA nutrients, it has attracted attention as one of the important high-quality fish i...
