Abstract

The invention discloses a high-yield crawfish culture method. The high-yield crawfish culture method comprises the following steps: (1) selection of a culture pond; (2) preparation before stocking; (3) stocking; (4) feeding; (5) water control. Through the mode, the high-yield crawfish culture method has the advantages of being high in survival rate, strong in vitality, sufficient in nutrition, natural and pollution-free, improved in yield and the like, and has a broad market prospect.

Description

The high-yield cultivation method of a kind of cray
Technical field
The present invention relates to aquaculture field, particularly relate to the high-yield cultivation method of a kind of cray.
Background technology
Aquaculture is one of industry that in China's livestock breeding, system is huge, pure wild aquatic organism yields poorly, survival rate is low, be unfavorable for extensive predation, and the cultivation of existing extensive aquaculture many employings greenhouse constant temperature, long-term feeding feed, in cultivation rapid-result within the time of production cycle, nutrition is not high, meat is not delicious, also can remain hormone in aquatic object, the health of serious harm eater.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the high-yield cultivation method of a kind of cray, by while the extensive raising of guarantee, simulation natural surroundings, follow growth cycle, cultivate according to the natural habit of cray, pure natural is nuisanceless, enhances vitality, improves output, has market prospects widely the popularizing of high-yield cultivation method of cray.
For solving the problems of the technologies described above, the invention provides the high-yield cultivation method of a kind of cray, comprising the following steps:
(1) culturing pool is selected: the lake that selection water depth is 1-1.2m, area is 3-5 mu, pH value is 6.5-8.5, stream, pond or rice field are as the culturing pool of lobster, the centre of culturing pool is built mud stalk and is built ramp prevent cray from playing cave flight for burrow cave, surrounding of cray, builds again anti-ly escape plate in the ramp surrounding of culturing pool;
(2) put front preparation in a suitable place to breed: in culturing pool, throw in base manure according to the ratio of every mu of 300-500kg, and plant pasture and water the place perched is provided to cray;
(3) throw in: select identical, the healthy great-hearted cray seedling of specification, in morning or the dusk of fine day, throw according to every square metre of 8-9 ratio only;
(4) feeding: early morning every day, 6-9 point threw in bait with dusk 4-7 point in the weather of temperature higher than 20 degrees Celsius, and the food quality controlling to throw at dusk be the 3-4 of the food quality that early morning throws in doubly, in the weather of temperature lower than 20 degrees Celsius early morning every day 6-9 point or dusk 4-7 point input bait;
(5) water body controls: every two weeks changes water once, each moisture changing 1/to three/5th of water body volume.
In a preferred embodiment of the present invention, the described base manure in step (2) comprise barnyard manure, chicken manure, cow dung, pig manure one or more.
In a preferred embodiment of the present invention, the described pasture and water in described step (2) comprise eel grass, water peanut, hydrilla verticillata, Eichhornia crassipes, water lettuce one or more.
In a preferred embodiment of the present invention, the cultivated area of the described pasture and water in step (2) is less than 1/3rd of culturing pool area.
In a preferred embodiment of the present invention, step (4) described bait comprise barnyard manure, chicken manure, cow dung, pig manure, trash fish, spiral shell freshwater mussel meat, silkworm chrysalis, earthworm, rice bran, wheat bran, pumpkin, sweet potato, fresh and tender pasture and water, soya bean, soya-bean cake, corn one or more.
The invention has the beneficial effects as follows: the advantages such as the high-yield cultivation method of cray of the present invention has that survival rate is high, vitality is strong, nutrient is sufficient, naturally nuisanceless, output increased, cray high-yield cultivation method universal on have market prospects widely.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A high-yield cultivation method for cray, comprises the following steps:
(1) culturing pool is selected: the lake that selection water depth is 1-1.2m, area is 3-5 mu, pH value is 6.5-8.5, stream, pond or rice field are as the culturing pool of lobster, adopt pond to coordinate with Natural Water to cultivate, cray is made to have natural growing environment, not anti-season growth, strictly follow growth cycle, the centre of culturing pool is built mud stalk and is built ramp prevent cray from playing cave flight for burrow cave, surrounding of cray, builds again anti-ly escape plate in the ramp surrounding of culturing pool;
(2) put front preparation in a suitable place to breed: in culturing pool, throw in base manure according to the ratio of every mu of 300-500kg, and plant pasture and water the place perched is provided to cray;
(3) throw in: select identical, the healthy great-hearted cray seedling of specification, in morning or the dusk of fine day, throw according to every square metre of 8-9 ratio only;
(4) feeding: early morning every day, 6-9 point threw in bait with dusk 4-7 point in the weather of temperature higher than 20 degrees Celsius, and the food quality controlling to throw at dusk is 3-4 times of the food quality that early morning throws in, in the weather of temperature lower than 20 degrees Celsius early morning every day 6-9 point or at dusk 4-7 point input bait, regular input feed can maintain the daily food ration of cray, fertilizer is organic nuisanceless, safe and practical, and then improve output, safety nuisance free, economical and practical;
(5) water body controls: every two weeks changes water once, and each moisture changing 1/to three/5th of water body volume, specifically makes change according to weather and actual conditions.
Preferably, the described base manure in step (2) comprise barnyard manure, chicken manure, cow dung, pig manure one or more.
