Embodiment 1

[0029] A kind of classification cultivation method of paraloach seedling, comprising:

[0030] Step 1: Set up the first cultivation pond: surface area 10 square meters, depth 50 centimeters; second cultivation pond: surface area 30 square meters, depth 60 centimeters; third cultivation pond: surface area 50 square meters, depth 80 centimeters.

[0031] Step 2: Prepare biological bait: put fermented peanut bran, eel feed, and fermented chicken manure into a pool for fermentation and cultivation for 7 days to obtain the biological bait; the water is changed once every 3 days.

[0032] Step 3: the yolk seedlings of Paraloach chinensis are placed in the first cultivation pond, so that the cultivation density of the yolk seedlings of Paraloach large scale in the first cultivation pond is 50000 tails / cubic meter, and with biological bait and egg yolk with 10: The weight ratio of 1 was mixed as the primary feed for 5 days, and the total length of the loach seedlings in the first cult...

Embodiment 2

[0036] The difference between this embodiment and embodiment 1 is:

[0037] Step 1: Set up the first cultivation pond: surface area 10 square meters, depth 50 centimeters; second cultivation pond: surface area 30 square meters, depth 60 centimeters; third cultivation pond: surface area 50 square meters, depth 80 centimeters; first cultivation pond , the bottom of the second cultivation pond, and the third cultivation pond and the surroundings are smooth, and the bottom and the horizontal plane have a 15° inclination, and a loach seedling collection pond 1 is provided at the lower end of the bottom. Described cultivating pond also comprises: inlet and drain device, comprises water inlet pipe 2, drainpipe 3 and pump 4, and the first end of described drainpipe 3 runs through the side wall of described loach seedling collecting pond 1 and communicates with the side wall of cultivating pond. liquid level, the second end of the drain pipe 3 stretches out of the cultivation pool, and...

Embodiment 3

[0040] The difference between this embodiment and embodiment 2 is:

[0041] Step 1: Set up the first cultivation pond: surface area 10 square meters, depth 50 centimeters; second cultivation pond: surface area 30 square meters, depth 60 centimeters; third cultivation pond: surface area 50 square meters, depth 80 centimeters; first cultivation pond , the bottom of the second cultivation pond, and the third cultivation pond and the surroundings are smooth, and the bottom and the horizontal plane have a 15° inclination, and a loach seedling collection pond 1 is provided at the lower end of the bottom. The water in the first cultivation pond adopts tap water, and it is pumped once every morning and evening, and the water volume replaced each time is 1 / 3 of the total water flow in the pond; the pond water in the second cultivation pond adopts tap water, and the water in the siphon cultivation pond is For residual bait and dirt, change the water once every 3 days, and the amount of ...

Abstract

The invention discloses a grading cultivation method of paramisgurnus dabryanus fries. The method includes carrying out primary cultivation on yolk fries of the paramisgurnus dabryanus to a total length of 1-1.5cm under a density of 50000 tails / cubic meter; then carrying out secondary cultivation to a total length of 2-2.5cm under a density of 10,000-20,000 tails / cubic meter;and finally, carryingout tertiary cultivation to a total length of 4-5cm under a density of 400-500 tails / cubic meter. According to the method, before the yolk fries of the paramisgurnus dabryanus grows to 2-2.5cm, the yolk fries of the paramisgurnus dabryanus is cultivated under the protection of a cultivation pool, so that the influence of pests on the yolk fries of the paramisgurnus dabryanus is reduced; when theyolk fries of the paramisgurnus dabryanus grows to 2-2.5cm, the eating of the pests can be resisted; and after the yolk fries of the paramisgurnus dabryanus grows to a total length of 4-5cm through three-grade cultivation, the yolk fries of the paramisgurnus dabryanus can instead take the pests as baits, so that the survival rate of the paramisgurnus dabryanus is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cultivating paraloach, and in particular relates to a method for cultivating seedlings of paraloach by classification. Background technique [0002] The individual of the large scale loach is large, grows fast, and its meat is tender, delicious, and has a high nutritional value. It is an important part of my country's aquatic product export. The usable part of the large scale loach accounts for more than 80% of the whole. It is rich in protein, calcium, phosphorus, and potassium. It also has the functions of nourishing and strengthening the body, clearing away heat and detoxification, diuresis and swelling, and clearing the milk. It is favored by consumers. , therefore, the cultivation of paraloach is of great significance. [0003] In the past, paraloach was bred and grown on its own, and then manually harvested to supply the demand. However, due to artificial overfishing and the aggravation of water p...
