Embodiment 1

[0041] Embodiment 1: A kind of water transport method for keeping live scallops of scallops, which is transported from the north to the south, including the following specific steps:

[0042] 1. Parental screening

[0043] Select robust, non-deformed, non-pathogenic scallops as parent shellfish. Parent shellfish are adult shellfish that can reproduce seedlings and have mature gonads. The parent shellfish has no damage, no wrong shells, and the two shells open and close after leaving the water. Lively; shellfish pillar is thick, mantle is well stretched, gills are clean, rectal feces are more, the size of the third-year-old shellfish is 10cm, and the ratio of female to male is 10:1;

[0044] 2. Cleaning to remove impurities

[0045] The scallops that have passed the screening are soaked and cleaned in clean seawater, and the water quality meets the national first-class sea water quality standard of GB3099 or the sea water meets the national fishery water quality standard of GB...

Embodiment 2

[0058] Embodiment 2: A water transport method for keeping live shellfish of Ezo scallop, transported from the north to the south, the steps are basically the same as in Example 1, the difference is that in step 1, 3.5-year-old shellfish with a size of 12 cm are selected. The male-to-female ratio is 13:1; the airtight cabin used in step 3 is an airtight and insulated cabin, and broilers are temporarily raised in the water tank in the form of hanging net cages. The hanging net cages are composed of plastic discs and netting clothes. Wrap in a plastic disc. The diameter of the plastic disc is 30cm, and there are several 1cm permeable holes drilled on the disc. The plastic disc is divided into 7-11 layers, and the layer spacing is 15-20cm. The netting is made of polyethylene, the mesh aperture is 2.8cm, surrounded by 18 strands of polyethylene woven net, the netting is wrapped with a plastic disc, and the net cage is cylindrical in shape as a whole. According to the specification...

Embodiment 3

[0059] Embodiment 3: A water transportation method for keeping live shellfish of Ezo scallop, transported from the north to the south, the steps are basically the same as in Example 1, the difference is that in the first step, a 4-year-old shellfish with a height of 13 cm is selected, and the shellfish of 13 cm is selected. The ratio of male to female is 15:1; the airtight cabin used in step 3 is an airtight and insulated cabin, and the broilers are placed in the tank layer by layer in a fence-like plastic frame. The size of the plastic basket is 1*0.6*0.3m, Put 20-30 scallops in each basket; in step 4, sea transportation is adopted, and during transportation, fresh, clean, stable physical and chemical properties can be replaced with low-temperature seawater that meets the standard; in step 5, the temperature of the temporary pool water is 7 ℃.

[0060] Carry out routine daily management of broilers until their eggs hatch. Including daily baiting, changing water, pouring the ...

Abstract

The invention belongs to the technical field of aquaculture, relates to a cultivation technique of parent scallops of patinopecten yessoensis, and in particular relates to a water transportation method for ensuring living parent scallops of patinopecten yessoensis. The method comprises the following steps: selecting healthy patinopecten yessoensis at the age of sexual maturity and without pathogenic bacteria as parent scallops, washing for removing impurities on the surfaces of the parent scallops, emptying excrement in the parent scallops, putting the parent scallops into a water tank in an airtight heat-insulation cabin, transporting the parent scallops to a destination in a low-temperature environment at 2-5 DEG C, and putting the parent scallops in a fostering pond at the water temperature of 3-7 DEG C for buffering and temporary keeping. By virtue of the method, the living transportation time reaches 72 hours, and the survival rate of the parent scallops is up to 99% and above. According to the method, the process is simple, the transportation cost is low, the equipment can be reused, and the operation and popularization are facilitated. The method can be used for effectively solving the bottleneck problem of high death rate during long distance transportation in processes of cultivating of fry of patinopecten yessoensis, introduction of fine varieties from abroad and marketing, and thus has important significance in promoting upgrading and low-carbon and energy-saving healthy sustainable development of industry of patinopecten yessoensis.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a technology for cultivating parent-child scallops, in particular to a method for water transportation of parent-child scallops to keep them alive. Background technique [0002] Ezo scallops are native to Japan, the southern waters of the Kuril Islands in Russia, Hokkaido in Japan and northern Honshu. They are excellent large cold-water shellfish. At present, Ezo scallop has become one of the main marine cultured shellfish in northern my country. Especially in the Liaodong Peninsula, Shandong Changdao and other sea areas. There are many ways to cultivate scallop broccoli, and now in the north of my country, there are mainly two methods: artificial factory temperature raising seedlings and semi-artificial seedling harvesting in natural sea areas. In the process of raising seedlings under artificial factory temperature in the north, the broodstock breeding process is easy to co...
