Embodiment 1

[0019] This embodiment provides a method for cultivating bamboo shoot shellfish, which includes the following steps.

[0020] Step 1, raising seedlings: when the water temperature in the pond reaches 20-25° C., carry out seedling raising, and the size of the fry is 2.5-3 cm. This is because bamboo shoot shell fry like to gather in small water bodies, and because the scales are barbed, it is easy to cause the head and tail of the fry to scratch each other and cause disease. The scales of fry of this size are tender and soft, and the chance of damage is small.

[0021] Bamboo shoot shell fish has the habit of drilling mud. In order to facilitate the capture and maintain stable water quality during the breeding period, the silt in the pond should be removed first, and disinfected with strong chlorine to remove miscellaneous fish and harmful microorganisms.

[0022] Step 2, multiplying algae: applying chemical fertilizers potassium nitrate 30-40ppm, potassium dihydrogen phosphate ...

Embodiment 2

[0033] This embodiment provides a method for cultivating bamboo shoot shellfish, which includes the following steps.

[0034] Step 1, raising seedlings: when the water temperature in the pond reaches 25-30° C., carry out seedling raising, and the size of the fry is 2-2.8 cm.

[0035] Step 2, multiplying algae: applying chemical fertilizers potassium nitrate 10-30ppm, potassium dihydrogen phosphate 2-4ppm, and cultivating a large amount of plankton.

[0036] Step 3, putting in fry: stocking 4000 bamboo shoot shell fry with a length of 2.5-3.5cm per mu.

[0037] Step 4, put in shrimp fry and fish fry for predation by bamboo shoot shell fish.

Abstract

The invention discloses a marbled sand goby culturing method. The method comprises the following steps of 1, fry culturing, wherein when the water temperature of a pond reaches 20-30 DEG C, fry culturing is performed, and the specification of the fry is 2-3 cm; 2, algae breeding, wherein 10-40 ppm of chemical fertilizer nitrate and 1-5 ppm of monopotassium phosphate are applied, and a large amount of plankton is cultured; 3, fry putting, wherein 4,000-6,000 pieces of marbled sand goby fry with the length being 2-3.5 cm are reared in each mu; 4, young shrimp putting, wherein young shrimps are put to be caught by marbled sand goby. The area of the pond is 3-5 mu, and the water depth is 1-2 m; the overall culture cycle is 12-15 months, and the fry survival rate reaches 80% or above. According to the marbled sand goby culturing method, the water quality is strictly controlled, the fry culturing process is standardized, breeding and culturing are performed according to life habits and characteristics of marbled sand goby, and the method has the great application and popularization value.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for cultivating bamboo shoot shellfish. Background technique [0002] The body shape of bamboo shoot shell fish is slightly elongated and strong, the front part is cylindrical and the rear part is slightly flattened, the head is flat and large, and the body width is about 1 / 3.5 of the body length. The eyes are protruding and located above the lips, the upper jaw is flanked by toothed bands, and the lower jaw is longer than the upper jaw. There is a row of small fangs, the scales on the body are in the shape of comb teeth, and there are four circles of black markings. The color of the abdomen is lighter, and the color of the body surface will change with the surrounding water quality and environment. [0003] Bamboo shell fish is a bottom-dwelling cave-dwelling fish. It often inhabits the sandy mud or grass at the bottom of rivers, reservoirs, and ponds with relative...
