Abstract
The invention provides a long-distance eriocheir sinensis crab conveying method. The long-distance eriocheir sinensis crab conveying method comprises the following steps of (1) selecting crabs which have no history of diseases, have complete appendages and are consistent in size; (2) fishing the crabs; (3) screening the crabs before conveying: placing the crabs in a net bag, draining off water, then placing the crabs in the center of a large basin, flatly laying the crabs, collecting the crabs which instinctively and rapidly crawl to the periphery of the basin and are high in physique, placing the collected crabs in a crab temporary raising tank made of a sieve with the mesh of 20-30 meshes, and placing the crabs in a clean water basin to vomit mud; (4) packaging the crabs; and (5) conveying the crabs. By using the long-distance eriocheir sinensis crab conveying method, the long-distance crab conveying yield is high, and conveying risks are reduced.
Description
technical field:
What the present invention relates to is a kind of Eriocheir sinensia button crab long-distance transportation method.
background technology:
Eriocheir sinensia is commonly called as river crab, and meat flavour is delicious, nutritious, is the high-quality aquatic food that liked by the people, and Jiangsu Yangcheng Lake steamed crab is well-known both at home and abroad.Seedlings of milieu crab is divided into megalops larva, young crab, detains three kinds of crabs, and button crab specification 3g-10g/ only.Along with culture of Chinese mitten crab industry carrying out in a deep going way throughout the country, the situation of long-distance transportation button crab is more and more, because transportation resources is improper, cause the situation of detaining the destruction of the crab survival rate Di Huo entire PLA also to happen occasionally therebetween, cause tremendous economic loss to vast culture of Chinese mitten crab person.About the relevant report of button crab long distance transportation aspect, still belong to blank at present.
summary of the invention:
The object that the present invention intends providing is in order to provide a kind of long distance transportation survival rate high, reduces the Eriocheir sinensia button crab long-distance transportation method of risk in transit.
The object of the present invention is achieved like this:
Eriocheir sinensia button crab long-distance transportation method of the present invention, comprises the following steps:
(1) button crab is selected: button crab will be without medical history, appendage is complete, specification is big or small basically identical;
(2) button crab is fished for;
(3) screening of button crab before transportation: button crab is packed in mesh bag water is drained, then put into large basin central, divide out, the button crab that physique is good creeps to surrounding rapidly by the light of nature, the button crab that climbs to surrounding is collected, pack the button crab made from 20-30 eye mesh screens into and support in case temporarily, then put into clear water reserviors and tell mud;
(4) packing of button crab;
(5) transportation: reduce dewatering time as far as possible, reduce the excursion of temperature, humidity in transportation, to improve transportation survival rate.
In above-mentioned step (2), adopt flowing water mass trapping to detain crab and fish for, daytime cultivation pond water position is lowered to 0.2-0.3m, then when dawn or dusk, in pond, wash by water, form 0.1-0.2m/s
3current, button crab can creep to water source voluntarily, now with net, by buckleing crab, catches again.
In above-mentioned method, adopt bubble chamber pack make-up crab to pack: first the button crab of handling well to be packed in 20 object mesh bags by every bag of 0.75kg.Bubble chamber by 60cm * 60cm * 40cm size, at the surrounding of bubble chamber and base angle, each makes a call to a duck eye, the duck eye of surrounding is beneficial to ventilation, base angle duck eye is convenient to discharge case internal water accumulation, thereby avoid detaining crab because of anoxic and soak dead, in each case, put into the ice cube 3kg sealing with plastic sack or freeze real 3000ml mineral water, at ice or above mineral water, put one deck dottle pin or pasture and water, avoid ice directly to contact with juvenile crab, then button crab bag is lain on dottle pin or pasture and water, every case fills 6 bags, then uses adhesive tape that cap seal is dead.
During above-mentioned transportation button crab, dewatering time is 12-16 hours, and transport temperature is 5-25 ℃, and humidity is 20-30%.
During above-mentioned transportation button crab, adopt air-conditioned coach, In transit, transportation temperature keeps 5～10 ℃.
The present invention makes Eriocheir sinensia button crab long-distance transportation survival rate high, and survival rate can reach more than 98%, reduces the risk of transportation, has improved economic benefit.
embodiment:
The present embodiment Eriocheir sinensia button crab long-distance transportation method, comprises button crab is selected, front button crab is fished for, transported to button crab screening, the packing of button crab, transportation five steps.Concrete steps are as follows:
(1) button crab is selected:
1) selected button crab will be without medical history, and appendage is complete; 2) the button crab specification size in same culturing pool is basically identical, without large and especially little especially specification, occurs.If occur, specification size is uneven, proves that this pond button crab inscribed between occurring in putting seedling or management process, should not select; 3) selected button crab will be in the mid-term of casting off a skin, both without soft crab also without stiff shell crab (referring to the stiff button crab that is about to shell of shell), avoid dead in transportation.
(2) button crab is fished for:
Adopt flowing water mass trapping, concrete grammar is daytime cultivation pond water position to be lowered to 0.2-0.3m, then when dawn or dusk, in pond, washes by water, and forms 0.1-0.2m/s
3current, button crab can creep to water source voluntarily, now with boring net, by buckleing crab, catches again.
(3) screening of button crab before transportation:
The button crab of appropriate (a 3kg left and right) is packed in mesh bag water is drained, then put into large basin central, divide out, the button crab that physique is good creeps to surrounding rapidly by the light of nature, the button crab that climbs to surrounding is collected, pack the button crab made from 30 eye mesh screens into and support in case temporarily, then put into clear water reserviors and " tell mud ", " telling mud " time is not less than 3h.Tell mud Main Function: be convenient to detain crab and discharge foul in body, improve survival rate.
(4) packing of button crab:
First the button crab of handling well is packed in 20 object mesh bags by every bag of 0.75kg.With the bubble chamber of 60cm * 60cm * 40cm size, at the surrounding of bubble chamber and base angle, each makes a call to a duck eye, and the duck eye of surrounding is beneficial to ventilation, and base angle duck eye is convenient to discharge case internal water accumulation, thereby avoids detaining crab because of anoxic and soak dead.In each case, put into the ice cube 3kg sealing with plastic sack or freeze 6 bottles of real mineral waters (500ml/ bottle), at ice or above mineral water, put one deck dottle pin or pasture and water, avoid ice directly to contact with juvenile crab, then button crab bag is lain on dottle pin or pasture and water, every case fills 6 bags, then uses adhesive tape that cap seal is dead.
(5) transportation: during transportation button crab, dewatering time is 12-16 hours, and transport temperature is 5-25 ℃, and humidity is 20-30%.
According to the length of transportation range and comfort level, select the means of transports such as automobile, aircraft.
Automobile Transportation be suitable for from railway and airport away from, the area of haulage time within 24h.Transportation button crab generally adopts air-conditioned coach, and fortune chien shih in seedling stage transportation temperature keeps 5～10 ℃, and transportation survival rate can approach 100%.Aircraft dispatch is applicable to disembark, and field is near, transportation range area far away.
Above-described embodiment is that foregoing of the present invention is further described, but this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to above-described embodiment.All technology realizing based on foregoing all belong to scope of the present invention.
