Abstract
The invention relates to a fry fishing, temporary rearing and transportation technique, which comprises the followings steps: (1) fishing: a push net made from polyethylene net cloth equipped with 15 to 25 meshes is used for saury fry fishing; saury fry with strong constitution is chosen together with water; (2) temporary rearing: salt is added to the natural river water after precipitation treatment; the temporary rearing temperature ranges between 26 DEG C to 27 DEG C, and the temporary rearing time is less than two hours; (3) transportation: water with the same water quality with the temporary rearing water is used; proper transportation density is maintained; the temperature of transportation water is controlled; ice is used for indirect cooling by the self dissolution of ice plastic bags arranged in the plastic bags used for saury fry transportation; when the saury fry is transported to destination and before the saury fry is arranged in the water, the water temperature of the fish pond should be adjusted to a temperature close to the transportation water temperature; then the saury fry is stocked in the fish pond. The technique has the advantages that, successful saury fry fishing, temporary rearing and transportation are carried out; the transportation survival rate of the saury fry is high.
Description
Technical field:
The present invention relates to a kind of fish seed catching and support transportation technology temporarily, more specifically to the seed transportation technology of a kind of hairtail.
Background technology:
Hairtail is one of famous the Changjiang river " three delicacies ", is famous and precious economic fish.Because environment and factor such as fish for, the resource decline is serious, and output descends year by year, the market price height, at present domestic have how tame colleges and universities, scientific research institutions all carrying out the artificial propagation research of hairtail, makes progress not really smoothly, and Zhong Yang group in Jiangsu is succeeding at the beginning of aspect the breed plantation technology of hairtail.Because the hairtail habit is more special, emergency reaction is extremely strong, and is extremely low to the poor environment endurance, water outlet is very easily dead, therefore, the first step of propagating artificially will be captured natural hairtail seedling exactly and be fished for a temporarily foster transportation technology difficult problem, guarantees the survival rate that the hairtail transportation is supported temporarily.
Summary of the invention:
The object of the present invention is to provide a kind of Saury seedling seed fishing, temporary rearing and transporting technique, successful tool setting fry kind is fished for and is supported transportation, hairtail seed transportation survival rate height temporarily.
Technical solution of the present invention is: a kind of Saury seedling seed fishing, temporary rearing and transporting technique is characterized in that: comprise the following steps:
1. fish for: get 15-25 purpose polythene net cloth and make to push net and fish for the hairtail seedling, operation is brisk, can not allow the dried up or tight water of hairtail (little volume water body squeezes fish), and band water is picked the hairtail seedling fish of physique stalwartness;
2. support temporarily: natural river after handle heavy fixed (18-24 hour), with salt (concentration 2-3.8 ‰), is supported temperature temporarily and is controlled at 26-27 ℃, and the time of supporting temporarily was less than 2 hours;
3. transportation: adopt above-mentioned steps 2. to support the treated water that uses temporarily, keep suitable traffic density, control transportation coolant-temperature gage, ice is placed in the plastic sack of transportation hairtail seedling dissolving voluntarily lowers the temperature indirectly with ice with the plastic sack bag, after the hairtail seedling is transported to the destination, before the gurry, earlier the water temperature in the fishpond is adjusted to water temperature near transportation, when water temperature to be transported and temperature of cultivation are close, the hairtail seedling is put in a suitable place to breed in the fishpond.
Above-mentioned steps 1. in, when selecting seed, reject the injured fry of fry, gynecological ailments of traction mud, swimming torpescence, many deformities earlier, get the hairtail seedling of physique stalwartness, the time is controlled in the 30min best.
2. foster temporarily density 200--400 tail/case (500kg water/case) when 2. above-mentioned steps supports temporarily, the time of supporting temporarily is preferably less than 90min.
3. above-mentioned steps transports time institute's water is natural river, and handle with salt through precipitation, salinity is 3 ‰~5 ‰, take band ice to wait measure to keep constant temperature (close with natural river water temperature, the temperature difference≤± 1 ℃) transportation, 26-27 ℃ of water temperature, haulage time≤3h, shipment density 35 tail/bags following (5kg water/bag).
3. above-mentioned steps transports time institute's water is the underground phreatic water of breed and the natural river of company, and both proportions are 2: 3 substantially, and the transportation water can be with the sudden and violent gas precipitation process of salt, and salinity is 3 ‰~5 ‰.
Above-mentioned steps has adopted the oxygenation of running water car oxygenation gas cylinder when 3. transporting.
The hairtail seedling that 1. above-mentioned steps is chosen does not carry out above-mentioned steps temporary supporting 2., directly carries out step and 3. transports, and now catches existing fortune, guarantees transportation survival rate.
The present invention can successfully fish for wild the Changjiang river hairtail and support transportation temporarily, effectively improves hairtail seed transportation survival rate, and method is simple, easy to be grasped, nuisanceless.
Embodiment:
The invention will be further described below in conjunction with example:
Example 1:
In September, 2007~October, the hairtail fry of doing nothing and catching in Anhui,
1. fish for: get 15-25 purpose polythene net cloth and make to push net and fish for the hairtail seedling, operation is brisk, can not allow the dried up or tight water of hairtail (little volume water body squeezes fish), reject the injured fry of fry, gynecological ailments of traction mud, swimming torpescence, many deformities earlier, get the hairtail seedling of physique stalwartness, time is controlled in the 30min best, and band water is picked the hairtail seedling fish of physique stalwartness;
2. support temporarily: natural river after handle heavy fixed (18 hours), with salt (concentration 2.5 ‰), is supported temperature temporarily and is controlled at 26-27 ℃, and the time of supporting was temporarily supported density 200--400 tail/case (500kg water/case) temporarily less than 1 hour;
3. transportation: adopt above-mentioned steps 2. to support the treated natural river that uses temporarily, and handle with salt through precipitation, salinity is 3 ‰~5 ‰, take band ice to wait measure to keep constant temperature (close with natural river water temperature, the temperature difference≤± 1 ℃) transportation, 26-27 ℃ of water temperature, haulage time≤3h, shipment density 35 tail/bags following (5kg water/bag) keep suitable traffic density, control transportation coolant-temperature gage, ice is placed in the plastic sack of transportation hairtail seedling dissolving voluntarily lowers the temperature indirectly with ice with the plastic sack bag, after the hairtail seedling is transported to the destination, before the gurry, earlier the water temperature in the fishpond is adjusted to water temperature near transportation, when water temperature to be transported and temperature of cultivation are close, the hairtail seedling is put in a suitable place to breed in the fishpond.
In the process of whole shipment fry, comprise and choose that seedling is got on the bus (selecting strong, that physique is strong, the do not come off fry of scale substantially of mobility) and when choosing seedling and going into the pond, all require overall process band water to operate, can not be dried up.
Should be controlled within the 30min from beginning to adorn seedling used time of whole process that the dress seedling finishes of getting on the bus.The interior water surface of bucket should can reduce the concussion back and forth of fry in transportation like this near the bucket top after the fry shipment finished, thus the damage of minimizing fish body.
