Abstract
The invention discloses a packing method for the transportation of blue crab megalopas and relates to a packing method for the megalopas. A packing method capable of enhancing survival rate of the megalopas during long-distance transportation and suitable for the transportation of the blue crab megalopas is provided. A dry ice bag is watered to produce ices, and each packing box is provided with a dry ice bag; the treatment prior to the package and transportation of the megalopas comprises the steps of: changing the water for the 3-day old blue crab megalopas one day before the package and transportation with accumulated water changing amount being not less than 100%; seeding-aggregating and cooling down: the blue crab megalopas are aggregated in a temporary pot and the water temperature is lowered to 22 DEG C; adding seawater and shelters for the blue crab megalopas to climb into a seeding bag, then putting the blue crab megalopas and filling the bag with oxygen with an amount which enables the bag to be equivalent to the packing box in volume, binding the seeding bag in which water temperature, salinity and pH as required by the water for the transportation and package are 20-22 DEG C, 28-32 and 7.5-8.5, respectively; placing the seeding bag into the packing box, covering the lid and sealing; packing the sealed internal packing box into the outer packing box.
Description
Technical field
The present invention relates to the packing method of a kind of megalops larva, especially relate to a kind of Scylla paramamosain (Scyllaparamamosain) megalops larva transportation packing method that is used for.
Background technology
Mud crab since have individual big, growth rapidly, characteristics such as strong, the delicious meat of adaptability, nutritious, nourishing and fit keeping function, anti-dried dew, easily transportation, economic worth height, become one of important mariculture crab class of coastal areas of southern China.Though the bionomic strategy of crab class belongs to r together and selects, the technical difficulty difference great disparity of artificial propagation between variety classes, river crab and swimming crab artificial breeding are of a mass character at present popularizes, and mud crab does not form artificial breeding of a mass character so far as yet; Simultaneously, the megalops larva seedling is not accepted in the mud crab crab farming that influences that is subjected to tradition to culture custom, only accepts young juvenile crab, and this has hindered the development of blue crab cultivation industry to a certain extent, so the transportation and packing of blue crab megalops also do not attract much attention, and still belongs to blank.At present, the report of juvenile crab transportation and packing aspect is detected in Eriocheir sinensia and swimming crab, mainly contains fortune method and the water transport method done.Do the fortune method and promptly juvenile crab directly is positioned over fortune seedling case, ventilate by transom window, regular trickle, perhaps juvenile crab is directly put into the plastics seedling bag that is full of oxygen; The water transport method is promptly with container band water oxygenations such as plastics seedling bag or canvas buckets, with the transportation resources of sealing or open type; (1.

Scylla paramamosain megalops larva natural disposition hobby cluster is united and is killed each other, and considerably beyond river crab and swimming crab, above-mentioned transportation and packing method is all inapplicable.
Also do not find the report of relevant Scylla paramamosain megalops larva transportation packing method so far as yet.
Summary of the invention
The present invention is intended to provide a kind of survival rate that improves the megalops larva long-distance transport at the packing aspect of existing Scylla paramamosain megalops larva transportation an open question still, is applicable to the blue crab megalops transportation packing method.
The present invention is applicable to 3～5 age in days blue crab megalops.
The present invention includes following steps:
1) the dry skating bag adds the water ice making, dry skating bag of each packing case configuration;
2) processing before the megalops larva transportation and packing: one day before the transportation and packing is that the 3rd day age in days blue crab megalops changes water, and the accumulative total quantity of exchanged water is no less than 100%;
3) collection seedling and cooling: blue crab megalops is accumulated in the temporarily foster net cage, water temperature is reduced to 22 ℃;
4) add seawater and blue crab megalops is sought connections with and veil toward the seedling bag, reinstall blue crab megalops, toward bag in fill oxygen, aeration quantity is suitable with the packing case volume, pricks the seedling sack, and the requirement of transportation dress seedling water is 20～22 ℃ of water temperatures, salinity 28～32, pH7.5～8.5;
5) go in the internal package box seedling is packed, cover case lid, sealing;
6) internal package box after will sealing is packed in the extranal packing box.
One day promptly the 3rd day age in days blue crab megalops before the transportation and packing changes water and preferably adopts segmentation to change the water mode to carry out; Change the water process and preferably throw sufficient bait, bait is preferably based on the fairy shrimp nauplius.The effect of changing water is to make it adapt to new seawater, reduces the unusual shell of transportation and suitably cooling.
In step 3), the rate of temperature fall of water temperature being reduced to 22 ℃ is preferably 2～3 ℃/h.
In step 4), the seedling bag can adopt plastic sack, and the amount that adds seawater is preferably 10～14kg, and blue crab megalops is sought connections with veil can adopt the plastics tennis, and the number that reinstalls blue crab megalops is preferably 2.0～3.0 ten thousand tails; When pricking the seedling sack, preferably allow blue crab megalops seek connections with and be suspension status with veil.
Described internal package box can adopt bubble chamber, and sealing can be adopted the gummed paper sealing.As run into after April 30, being preferably in top, seedling bag outside and placing one bag of dry skating, the best in quality of dry skating is 600～700g.Usually after April 30, temperature is higher.
Described extranal packing box can adopt carton.
The packing aspect that the present invention has overcome the transportation of existing Scylla paramamosain megalops larva is an open question still, preceding preliminary treatment, cooling temperature control are packed in employing and setting is sought connections with and veil---technical measures such as suspension type net sheet ball, when guaranteeing to transport survival rate, reduce transport stress as far as possible, guarantee that seed quality (productivity) is unaffected, improve the survival rate of blue crab megalops long-distance transport significantly, under the normal condition, general transportation survival rate can reach more than 95%.The present invention is specially adapted to 3～5 age in days blue crab megalops.
