Example Embodiment
[0026] Example 1: A method of keeping alive and dry transportation of Yezo scallop relatives, which is transported from the north to the south, including the following specific steps:
[0027] (1) Screening of relatives
[0028] Choose scallops that are robust, non-deformed, reach sexual maturity, and do not carry pathogenic bacteria as the parent shells, and the size is 3 years of age shells of 10cm;
[0029] Broodstock are adult shellfish with mature gonads that can breed shellfish;
[0030] (2) Clean to remove impurities
[0031] The selected Ezo scallop parent oysters are immersed and cleaned in clean seawater that meets the national first-class seawater quality standards to remove impurities and dirt mixed in the Ezo scallop parent oysters;
[0032] (3) Put into the incubator
[0033] Put the cleaned Ezo scallop scallops into the prepared incubator, and place moist seaweed, cotton or linen cloth on the scallops with a good absorbent and large surface area, and then put the frozen sea...
Example Embodiment
[0039] Example 2: A method of keeping alive and dry transportation of Yezo scallop parent shells, transported from the north to the south, the steps are basically the same as in Example 1, the difference is that: in step (1), the 3.5-year-old shells of 12 cm are selected ; In step (3), the amount of parent shells accounted for 75% of the volume of the incubator, and the moisture-absorbing covering accounted for 15%, leaving 10% of the volume of air; in step (4), the incubator was placed in a low temperature environment of 3°C By sea; the temperature of the holding tank water in step (5) is 5°C.
Example Embodiment
[0040] Example 3: A method of keeping alive and dry transportation of Yezo scallop relatives, transported from the north to the south, the steps are basically the same as in Example 1, the difference is that: in step (1), 13cm 4-year-old scallops are selected ; In step (3), the amount of parent shells occupies 77% of the volume of the incubator, and the moisture-absorbing cover accounts for 18%, leaving 5% of the volume of air; in step (4), the incubator is placed in a low temperature environment of 5°C. Air transport; the temperature of the holding tank water in step (5) is 7°C.

Abstract
The invention belongs to the technical field of aquaculture, and relates to the technology of culture of oyster parents of patinopecten yesoensis, in particular to a keep-alive dry transportation method for the oyster parents of patinopecten yesoensis. The method comprises the steps that healthy patinopecten yesoensis reaching the sexual maturity ages and carrying no pathogenic bacteria is selected as the oyster parents, and the oyster parents are loaded into a heat preservation box after impurities on the surfaces of the oyster parents are washed away and removed; the loading quantity is controlled according to the specification of the oyster parents; the loading quantity of the oyster parents accounts for 73% to 77% of the volume of the heat preservation box, and bottled freezing sea water, wet sea grass and cotton cloth or linen and other covering materials with good water absorption performance and the large superficial area are placed in the heat preservation box; the moisture absorption covering materials account for 12% to 18%, and air space accounting for 5% to 15% of the volume of the heat preservation box is additionally reserved; the heat preservation box is placed in a low-temperature environment at the temperature 2 DEG C to 5 DEG C to be transported after being sealed by adhesive tape, and the heat preservation box is placed in low-temperature water at the temperature of 4 DEG C for buffer recovery after reaching a destination. The method is simple in process, low in packaging and transporting cost and convenient to operate and popularize, the keep-alive transportation time reaches 30 hours, the survival rate reaches 99% or above, and long-distance keep-alive transportation of the oyster parents is achieved. The transportation problem of southward moving juvenile growing of shellfishes is effectively solved, and great significance is achieved on promoting upgrading and low-carbon, energy saving, healthy and sustainable development of the patinopecten yesoensis industry.
Description
Technical field [0001] The invention belongs to the technical field of aquaculture, relates to a technique for cultivating Ezo scallop parent molluscs, and specifically relates to a method of keeping alive and dry transportation of the Ezo scallop parent molluscs. Background technique [0002] Ezo scallops are native to Japan, the southern waters of the Russian Kuril Islands, Hokkaido, Japan and northern Honshu. They are excellent large-scale cold-water shellfish. At present, the Yezo scallop has become one of the main marine shellfish in northern my country. Especially in the Liaodong Peninsula, Shandong Changdao and other sea areas. There are many ways to cultivate Ezo scallop parent shells. Now in northern my country, it is mainly divided into two ways: artificial factory raising seedlings and semi-artificial seedlings in natural sea areas. In the process of raising seedlings in artificial factories in the north, the breeding process of broodstock is easy to control, but wat...
