Embodiment 1

[0049] Such as figure 1 , 2 Shown in , 4: the present invention comprises a plurality of culturing ponds 10 arranged in parallel in the water circulation treatment system, the upstream of the cultivating pond 10 is provided with a water injection branch pipe 21 for injecting water into the cultivating pond 10, and the downstream of the cultivating pond 10 is provided with There is a drainage pipe 11, the drainage pipe 11 is vertically arranged on the bottom surface of the cultivation pond and the side surface of the drainage pipe 11 is provided with a water inlet 12, and the drainage pipe 11 is provided with a drainage hole installed at the bottom of the cultivation pond. The overflow pipe 13, the upper end of the overflow pipe 13 forms an overflow port 14, the height of the overflow port 14 is flush with the water surface of the cultivation pond 10, and the mesh cloth to prevent fry from escaping is installed at the water inlet hole 12 . The specification of the mesh cloth:...

Embodiment 2

[0057] Such as image 3 As shown: the difference from Example 1 is that when the cultivation pool 10 is composed of a circular groove, the water outlet front end of the water injection branch pipe 21 forms an elbow structure 21b that can rotate 360 ​​degrees around the axial direction of the water injection branch pipe. The head structure 21b is arranged on the edge of the cultivation tank. The bottom surface of the cultivation pond is arranged obliquely from the edge to the middle with an inclination angle of 3-5 degrees, the elbow structure 21b is located at the edge of the cultivation pond, and the drain pipe 11 is located in the middle of the cultivation pond. Outline dimensions of the circular tank: φ1.0m×1.0m high.

[0058] Multiple circular tanks are installed in the same room at the same time, and the multiple circular tanks are connected to the industrial water circulation treatment system through pipelines, which can be used for large-scale seedling cultivation; the...

Abstract

The invention discloses a factory cultivation method for maccullochella peelii fry. The method comprises the steps of establishment of a fry cultivation system and a fry staged cultivation process; the fry cultivation system comprises a plurality of cultivation pools arranged in parallel in a water circulation processing system; and the fry staged cultivation process includes the following stages:0-15-day-old fry initial-eating cultivation, 15-30-day-old fry temporary rearing cultivation, 30-45-day-old fry feed change domestication cultivation, 45-90-day-old fry cultivation, and late cultivation. The method disclosed by the invention makes quality of water in the cultivation pools easy to control through the fry cultivation system, is convenient for prevention and control of diseases andmanagement, reduces probability that the whole batch of the fry is infected with the diseases, and greatly improves a survival rate of fry cultivation; and the fry staged cultivation process greatly improves a survival rate and an initial-eating ratio of the maccullochella peelii fry and a survival rate of the maccullochella peelii fry entering the pools, and obtains higher production benefits.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for industrialized cultivation of Australian dragonfly fry. Background technique [0002] Australian dragon striped (Maccullochella peelii), also known as Murray cod, river cod, cod perch, Australian freshwater cod perch, etc., mainland China is called Australian dragon striped, worm pattern cod perch or worm pattern grouper, native to Australia The Murray Darling River Basin in the southeast is one of the four main warm-water freshwater fishes in Australia. Its meat is firm, white and tender, delicious, no fishy smell, and has a faint unique fragrance. The meat is tender and has few thorns. It is rich in four kinds of amino acids, EPA and DHA, and its nutritional value is quite high. It is known as "National Treasure" in Australia. Fish" nickname. The breeding of Australian dragon stripes in my country is still in the preliminary stage. Only a few ente...
