Embodiment 1

[0021] 1) Add water to the roller skating bag to make ice, and each packing box is equipped with a roller skating bag;

[0022] 2) Treatment of megalopa before transportation and packaging: the day before transportation and packaging, that is, the third day-old blue crab megalopa, the water should be changed. During the water process, enough bait is cast, and the bait is mainly Artemia nauplii.

[0023] 3) Collection of seedlings and cooling: gather the blue crab megalopa in temporary culture cages, lower the water temperature to 22°C, and the cooling rate for lowering the water temperature to 22°C is 2-3°C / h.

[0024] 4) Add 12kg of seawater and the clinging and sheltering objects of the blue crab megalopa to the plastic seedling bag, then fill in 20,000 to 30,000 tails of the blue crab megalopa, fill the bag with oxygen, the amount of air inflated is equivalent to the volume of the packing box, and prick the seedlings. The requirements for the bag mouth and the water used f...

Embodiment 2

[0031] Similar to Example 1, the difference is that the test date was May 24, and a certain aquatic nursery farm used this method to transport 1 million blue crab megalopa larvae to Changhua, Taiwan by means of vehicle transportation and air transportation. It is: the transportation time from an aquatic product nursery to Xiamen Airport is 3.5 hours, the air transportation time from Xiamen to Shenzhen is 1.5 hours, the transportation time from Shenzhen to Hong Kong is 1.5 hours, and the air transportation time from Hong Kong to Changhua, Taiwan is 2 hours. , The cumulative time is 19h, and the transportation survival rate is 95%.

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 20-22DEG 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 [0001] The invention relates to a packing method for megalopa, in particular to a packing method for transporting megalopa of Scyllaparamamosain. Background technique [0002] Due to its large size, rapid growth, strong adaptability, delicious meat, rich nutrition, nourishing and strengthening body, resistance to dry dew, easy transportation, and high economic value, blue crab has become one of the important marine cultured crabs in the southern coast of my country. Although the ecological countermeasures of crabs belong to r selection, the technical difficulty of artificial propagation varies greatly among different species. At present, the artificial breeding of river crabs and portunus has become popular among the masses, while blue crabs have not yet formed mass artificial breeding; at the same time, influenced by traditional breeding habits The impact of blue crab crab farmers does not accept the megalopa seedlings, only larvae seedlings, which hinders t...
