Abstract
The invention discloses a method of performing polyculture to an Odontobutis obscura in a crab pool, and belongs to the field of aquaculture. The method comprises the following steps of: in February to March, self-fertile crabs and Odontobutis obscura parents are placed in a pool, or in May, the self-fertile crabs and the Odontobutis obscura parents are placed in the pool; before stocking, the crabs and fishes are respectively disinfected and sterilized; river crab baits are placed into the pool to feed the crabs and the fishes; during a cultivation period, fresh water is periodically injected into the crab pool, and applied with microbial preparations, such as photosynthetic bacteria, EM (effective microorganisms) bacteria and bacillus, and bottom modifying products to improve water quality and substrate; and during the cultivation period, a waterweed area is controlled to be 1/3-1/2 of a whole water surface; and the crab pool is performed with insect killing and disinfected at regular intervals. In the method, growth and physiological characteristics of the Odontobutis obscura and river crabs are integrated, and the fishes and the crabs are reasonably managed and fed, thus, both yields are improved; 15-20kg of fishes and the crabs can be obtained per Mu, and economic benefits of the crab pool in a unit area is improved by 25%-30%.
Description
Technical field
The present invention relates to aquaculture field, relate in particular to the method that Odontobutis obscura is raised together with in a kind of crab pond.
Background technology
A few days ago, along with popularizing of culture of Chinese mitten crab industry, cultured area constantly increases, and the output of river crab also constantly increases, and the market price of commodity crab is but more and more lower, causes the economic benefit of culture of Chinese mitten crab not satisfactory.Odontobutis obscura is subordinate to Perciformes, Eleotridae, and Odontobutis is a kind of small-sized economic freshwater fish; Its muscle thorn is few, and it is high to contain the meat amount, nutritious.River crab and crucian, the foster method of mandarin fish cover reach its maturity at present, but along with the exploitation of economic fingerling and the variation of people's demand, Odontobutis obscura also receives people's favor gradually, but the method that river crab and Odontobutis obscura cover are supported did not occur at present.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide the method that Odontobutis obscura is raised together with in a kind of a kind of crab pond of improving culture efficiency and economic benefit.
Technical scheme: in order to realize the foregoing invention purpose, the method for Odontobutis obscura is raised together with in a kind of crab of the present invention pond, comprises the steps:
(1) with 2 ~ March self-fertile button crab and Odontobutis obscura parent are put into the pond, or self-fertile button crab and Odontobutis obscura parent are put into the pond, before putting in a suitable place to breed crab kind and fingerling are carried out disinfection respectively and sterilization May;
(2) the river crab bait of throwing something and feeding;
(3) culture during, the regular filling fresh water toward the crab pond, and use microorganism formulation such as photosynthetic bacteria, EM bacterium and bacillus and the end and change series products and improve water quality is improved substrate; And control pasture and water area accounts for 1/3 ~ 1/2 of the whole water surface during culturing; And desinsection and sterilization regularly.
Said button crab is to detain crab one-year-old age, soaks 3 ~ 5 minutes in the saline solution before said button crab is put in a suitable place to breed again; Said Odontobutis obscura fingerling stocking is preceding with the dipping of 10ml/L potassium permanganate.
In the said step (2), when river crab body weight during less than 20g, throw something and feed young crab pellet, dregs of beans and fresh wild fishes; When river crab body weight during, throw something and feed and soaked wheat, corn, soya bean and the freezing fish of boiling greater than 20g;
Time 4 ~ 5 points in the afternoon of throwing something and feeding.
Get into after June, water filling in per 7 ~ 10 days once, each water filling 10 ~ 20cm.
Beneficial effect: the method synthesis Odontobutis obscura of Odontobutis obscura and growth, the physilogical characteristics of river crab are raised together with in a kind of crab of the present invention pond; Through rational management and raising; Improved output separately, can gather in the crops 15 ~ 20 kilograms for every mu, the economic benefit in unit are crab pond improves 25%-30%.
Embodiment
Through specific embodiment the present invention is described further below:
The method of Odontobutis obscura is raised together with in a kind of crab of the present invention pond, comprises the steps:
(1) with 2 ~ March self-fertile button crab and Odontobutis obscura parent are put into the pond, or self-fertile button crab and Odontobutis obscura parent are put into the pond, before putting in a suitable place to breed crab kind and fingerling are carried out disinfection respectively and sterilization May;
(2) the river crab bait of throwing something and feeding; When river crab body weight during less than 20g, throw something and feed young crab pellet, dregs of beans and fresh wild fishes; When river crab body weight during, throw something and feed and soaked wheat, corn, soya bean and the freezing fish of boiling greater than 20g; Time 4 ~ 5 points in the afternoon of throwing something and feeding.
(3) culture during, the regular filling fresh water toward the crab pond, and use microorganism formulation such as photosynthetic bacteria, EM bacterium and bacillus and the end and change series products and improve water quality is improved substrate; And control pasture and water area accounts for 1/3 ~ 1/2 of the whole water surface during culturing; And desinsection and sterilization regularly.
The button crab is to detain crab one-year-old age, soaks 3 ~ 5 minutes in the saline solution before the button crab is put in a suitable place to breed again; The Odontobutis obscura fingerling stocking is preceding with the dipping of 10ml/L potassium permanganate.
Get into after June, water filling in per 7 ~ 10 days once, each water filling 10 ~ 20cm.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
