Abstract
The invention discloses a high density crab culture method comprising the following steps: a, selecting a culture pond; b, cleaning and disinfecting the pond; c, transplanting waterweed; d, selecting crab sprouts; e, daily sampling and feeding. By using the method, the food can be fed to the crabs at regular time with fixed quantity every day; the food fed to the crabs can be timely adjusted according to crab weight, thus preventing crab nutrition insufficient absorption, and improving crab yield; the waterweed is natural food for the crabs, rich in nutrition, and can reduce crab feeding cost.
Description
Technical field
The present invention relates to a kind of high-density crab culture method.
Background technology
Crab is a kind of aquatic products, and it contains rich in protein and trace element, has good tonic effect to health, and it also has antiphthisic medical value, has help greatly to rehabilitation lungy.Because its meat is fine and smooth delicious, become the course that people like very much.But existing crab per mu yield is lower, and economic benefit is low, and feeding cost is high, can not meet the demand in market, be therefore necessary to provide a kind of new cultural method to solve the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of high-density crab culture method that feeding cost is low, output is high.
To achieve these goals, the technical solution adopted in the present invention is as follows:
A kind of high-density crab culture method, comprises the following steps:
A) culture pond is selected: selection is had abundant water resources, enter draining convenience, water quality is well pollution-free, there is the dark mud of 10-20cm at the bottom, the depth of water is 40-70cm, area is that the pond of 3-5 mu is as culture pond;
B) to clean up the pond sterilization: be sprinkled upon uniformly in described culture pond by quicklime and carry out disinfection, on average every mu is sprinkled into 50-60 kilogram of quicklime;
C) pasture and water are transplanted: in described culture pond, plant the pasture and water that crab can eat, pasture and water cultivated area accounts for the 40-55% of the culture pond water surface gross area;
D) select juvenile crab: select neat specification, step is complete, physique is healthy and strong, creep active, body weight anosis without wound is the juvenile crab of 4-6 gram, is in 1: 3 input pond, only throws in 1650-1700 for every mu with male and female ratio;
E) daily sampling with throw something and feed: within every 10 days, fish for 15-20 crab at random, calculate its average weight, estimate the gross weight of all crabs, every morning, 8-9 point was thrown something and fed a food, afternoon, 4-5 point was thrown something and fed a food, and the weight of food of throwing something and feeding every day is the 4.5%-6% of crab gross weight; Described food comprises plant feed and animal feed, and the weight ratio of described plant feed and animal feed is 2: 3.
Preferably, steps d) described in pasture and water comprise in duckweed, Azolla imbricata, weter hyacinth, water lettuce, hornwort, eel grass and water peanut one or more.
Preferably, step e) described in plant feed comprise in soya-bean cake, groundnut cake, corn and wheat one or more.
Preferably, step e) described in animal feed comprise small fish, shrimp and pluck.
Compared with prior art, the beneficial effect of high-density crab culture method of the present invention is: at regular time and quantity, the food of throwing something and feeding every day adjusts according to crab body weight the food of crab every day in time, prevents crab nutrition intake not enough, is conducive to improving crab output; Described pasture and water are the natural food of crab, nutritious, can reduce the feeding cost of crab.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
The invention provides a kind of high-density crab culture method, comprise the following steps:
A) culture pond is selected: selection is had abundant water resources, enter draining convenience, water quality is well pollution-free, there is the dark mud of 10-20cm at the bottom, the depth of water is 40-70cm, area is that the pond of 3-5 mu is as culture pond;
B) to clean up the pond sterilization: be sprinkled upon uniformly in described culture pond by quicklime and carry out disinfection, on average every mu is sprinkled into 50-60 kilogram of quicklime;
C) pasture and water are transplanted: in described culture pond, plant the pasture and water that crab can eat, pasture and water cultivated area accounts for the 40-55% of the culture pond water surface gross area;
D) select juvenile crab: select neat specification, step is complete, physique is healthy and strong, creep active, body weight anosis without wound is the juvenile crab of 4-6 gram, is in 1: 3 input pond, only throws in 1650-1700 for every mu with male and female ratio;
E) daily sampling with throw something and feed: within every 10 days, fish for 15-20 crab at random, calculate its average weight, estimate the gross weight of all crabs, every morning, 8-9 point was thrown something and fed a food, afternoon, 4-5 point was thrown something and fed a food, and the weight of food of throwing something and feeding every day is the 4.5%-6% of crab gross weight; Described food comprises plant feed and animal feed, and the weight ratio of described plant feed and animal feed is 2: 3.
In step b) in, described quicklime and water generation chemical reaction generate slaked lime, can kill the bacterium in water and other harmful microorganism, prevent crab bacteria infection, calcium constituent can be provided for the growth of crab after slaked lime is water-soluble, be convenient to improve crab output.
Step c) described in pasture and water comprise in duckweed, Azolla imbricata, weter hyacinth, water lettuce, hornwort, eel grass and water peanut one or more.
Step e) described in plant feed comprise in soya-bean cake, groundnut cake, corn and wheat one or more, described animal feed comprises small fish, shrimp and pluck.Described pasture and water can provide natural organic food for crab real-time on-site, reduce the feeding cost of crab, described pasture and water also contribute to purifying water, reduce the onset risk of crab, the plant feed of wide variety and animal feed can provide nutrition abundant more comprehensively for crab, are convenient to crab and grow fast.
In addition, timing sampling of the present invention measures the body weight of crab, can the upgrowth situation of Real-Time Monitoring crab, and according to the upgrowth situation adjustment appetite of crab, prevents crab nutrition intake not enough, be conducive to improving crab output.
Schematically above be described the present invention and embodiment thereof, this description does not have restricted, and actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the invention aim, designing the frame mode similar to this technical scheme and embodiment without creationary, all should protection scope of the present invention be belonged to.
