Embodiment 1

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

[0030] Step 1: Set up a first-level cultivation pond: a surface area of ​​10 square meters and a depth of 50 centimeters; a second-level cultivation pond: a surface area of ​​30 square meters and a depth of 60 centimeters; a third-level cultivation pond: a surface area of ​​50 square meters and a depth of 80 centimeters.

[0031] Step 2: Preparation of biological bait: Put the 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 was changed once every 3 days.

[0032] Step 3: the yolk seedlings of Paraloach chinensis are placed in the first-level cultivation pond, so that the cultivation density of the yolk seedlings of Paraloach large scale in the first-level cultivation pond is 50000 tails / cubic meter, and with biological bait and egg yolk with 10: The weight ratio of 1 was mixed as t...

Embodiment 2

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

[0037] Step 1: Set up a first-level cultivation pool: a surface area of ​​10 square meters and a depth of 50 cm; a second-level cultivation pool: a surface area of ​​30 square meters and a depth of 60 cm; a third-level cultivation pool: a surface area of ​​50 square meters and a depth of 80 cm; a first-level cultivation pool 1, the bottom of the secondary cultivation pond, and the bottom of the three-stage cultivation pond 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...

Embodiment 3

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

[0041] Step 1: Set up a first-level cultivation pool: a surface area of ​​10 square meters and a depth of 50 cm; a second-level cultivation pool: a surface area of ​​30 square meters and a depth of 60 cm; a third-level cultivation pool: a surface area of ​​50 square meters and a depth of 80 cm; a first-level cultivation pool 1, the bottom of the secondary cultivation pond, and the bottom of the three-stage cultivation pond 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-level cultivation pool is tap water, and it is pumped and discharged once every morning and evening, and the water volume replaced each time is 1 / 3 of the total water volume in the pool; the water in the secondary cultivation pool is tap water, and the For residual bait and dirt, change the water once every 3 d...

Abstract

The invention discloses a method for cultivating the yolk seedlings of Paraloach chinensis by grade at a density of 50,000 tails / cubic meter to a full length of 1 to 1.5 centimeters; then 10,000 to 20,000 tails At a density of 400-500 tails per cubic meter, it will be cultivated in two stages to a total length of 2 to 2.5 cm; finally, at a density of 400 to 500 fish per cubic meter, it will be cultivated in a third stage to a total length of 4 to 5 cm. The present invention reduces the influence of predators on the yolk seedlings of the paraloach by cultivating them under the protection of the cultivation pond before the yolk seedlings of the paraloach grow to 2 to 2.5 centimeters. When the yolk seedlings of the paraloach grow to After 2-2.5 centimeters, it can resist the niggling of predators, and after three-level cultivation to a total length of 4-5 centimeters, the yolk seedlings of Paraloach grandis can use predators as bait instead, thus greatly improving the Survival of paraloach.

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...
