Abstract
The invention provides a crayfish culture method. The method comprises pond construction, putting compound fertilizers into the water for water enrichment, algae planting and management. The crayfish culture method has the following advantages: by using the method provided by the invention, the disease resistance of crayfish is improved, the yield of crayfish is increased, and at the same time, the economic benefit is improved.
Description
Technical field
The present invention relates to aquaculture technical field, particularly relate to the cultural method of cray.
Background technology
The nutrition of cray is well-known, and current cray cultivation is in China's fast development, and cray is in developmental process, cray easily catches, often bite each other, the output causing cray cannot effectively improve, and reduces economic benefit simultaneously simultaneously.
Summary of the invention
In order to solve the problems of the prior art, the invention provides the cultural method of a kind of cray.
The invention provides the cultural method of a kind of cray, comprise the steps:
Pond is built: pond is provided with water inlet and delivery port, and is equipped with at water inlet and water outlet and anti-escapes net;
Training water, after the water inlet of pond, applies composite fertilizer and carries out training water in water body;
Plantation algae: plant algae in described culturing pool, form useful algae phase, the area coverage forming algae is greater than 50% of whole culturing pool area;
Throw in cray seedling: put 9-11 ten thousand tail cray in a suitable place to breed for every mu;
Management: throw in cray feed in pond, feed divides three inputs, throws in the 12-18% of injected volume on the same day morning; Throw in the 40-50% of day injected volume afternoon; Throw in the surplus of day injected volume during 8 o'clock to 9 o'clock evening, and day injected volume be 65% of cray body weight, in addition, need to ensure that amount of oxygen changed water once at 6.3-8.0mg/L, 6-8 days in culturing pool, sterilization in 10-15 days once, until catch.
As a further improvement on the present invention, in training water step, the temperature of the water body of water inlet is 20-22 DEG C.
As a further improvement on the present invention, in training water step, the pH value of the water body of water inlet is 6.5-7.
The invention has the beneficial effects as follows: adopt method of the present invention, improve the resistance against diseases of cray, improve the output of cray, improve economic benefit simultaneously.
Embodiment
The invention discloses the cultural method of a kind of cray, comprise the steps:
Pond is built: pond is provided with water inlet and delivery port, and is equipped with at water inlet and water outlet and anti-escapes net;
Training water, after the water inlet of pond, applies composite fertilizer and carries out training water in water body;
Plantation algae: plant algae in described culturing pool, form useful algae phase, the area coverage forming algae is greater than 50% of whole culturing pool area;
Throw in cray seedling: put 9-11 ten thousand tail cray in a suitable place to breed for every mu;
Management: throw in cray feed in pond, feed divides three inputs, throws in the 12-18% of injected volume on the same day morning; Throw in the 40-50% of day injected volume afternoon; Throw in the surplus of day injected volume during 8 o'clock to 9 o'clock evening, and day injected volume be 65% of cray body weight, in addition, need to ensure that amount of oxygen changed water once at 6.3-8.0mg/L, 6-8 days in culturing pool, sterilization in 10-15 days once, until catch.
