Embodiment 1

[0020] A kind of fore fin plateau loach seed cultivation method, comprises the steps:

[0021] (1) Temporary raising of fish fry: When the water temperature is 16°C, temporarily raise 500 fish fry in a large plastic basin with a diameter of 50 cm. The water depth in the basin is 10 cm. Equipped with two 300-watt heating rods, keep the water temperature at 16°C to prevent excessive temperature difference between day and night caused by too little water in the plastic basin. The holding time is 6 days, and the fry will be opened after the yolk sac disappears to a line;

[0022] (2) Fry opening: Use the cultivated chlorella to open the fry, put the chlorella into the water and disperse it in the water, feed it twice a day, the amount of each feeding is 0.1g / L water body, change the water once 6 hours after feeding , the amount of water change is 30% of the amount of cultured water. After the first feeding, take a small amount of fry and observe under the dissecting microscope. If...

Embodiment 2

[0032] A kind of fore fin plateau loach seed cultivation method, comprises the steps:

[0033] (1) Temporary fish fry: When the water temperature is 15°C, 500 fish fry are temporarily raised in a large plastic basin with a diameter of 50cm. The water depth in the basin is 10cm. Equipped with two 300-watt heating rods, keep the water temperature at 15°C to prevent excessive temperature difference between day and night caused by too little water in the plastic basin. The holding time is 5 days, and the fry will be opened after the yolk sac disappears to a line;

[0034] (2) Fry opening: Use the cultivated chlorella to open the fry, put the chlorella into the water and disperse it in the water, feed it twice a day, the amount of each feeding is 0.1g / L water body, change the water once 6 hours after feeding , the amount of water change is 30% of the amount of cultured water. After the first feeding, take a small amount of fry and observe under the dissecting microscope. If food is...

Abstract

The invention discloses a method for cultivating forefin plateau loach seedlings, comprising the following steps: (1) temporarily raising fish fry, (2) opening the fish fry, (3) live bait feeding stage, (4) water earthworm feeding stage, (5) feeding stage, (6) fingerling cultivation stage, (7) disease prevention and control; the present invention successfully realizes the artificial cultivation of forefin plateau seedlings for the first time in China through the precise control of the above-mentioned 7 steps, and the seedlings The survival rate of the species reaches more than 92%, and the method is simple and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of fish breeding, and in particular relates to a method for cultivating forefin plateau loach seedlings. Background technique [0002] The front fin plateau loach is a fish belonging to the genus Plateau Loach of the family Loachidae of Cyprinidae. The body is elongated, and the rear part gradually becomes flattened, and the height of the caudal peduncle is almost unchanged. The head is short, the front end is blunt, slightly depressed. Snout equal to or slightly longer than head behind eyes. Mouth lower, upper lip with papillae, lower lip thin, with shallow wrinkles. Mandible shovel-shaped, exposed outside the lips. With 3 pairs of whiskers. The dorsal fin is longer, the outer edge is truncated, and the unbranched fin rays are soft. Its starting point is more forward, and the distance from the tip of the snout is 0.8-0.9 times the distance from the base of the caudal fin. The pectoral fin is longer. Op...
