Embodiment 1

[0030](1) From March 15th to 20th, 2008, mature individuals of sea cucumbers grown in sea areas for two years were selected from Nanri Island in Fujian and Yantai in Shandong as parent ginseng (among them, 50% of the ginseng were collected from Nanri Island in Fujian and grown in the sea area. 2-year-old mature sea cucumber individuals, 50% of which are collected from mature sea cucumber individuals grown for 2 years in the Yantai sea area of ​​Shandong). The ginseng was transported to Shengde Abalone Seed Breeding Field in Xiuyu District, Putian City, Fujian Province by means of low-temperature and wet transportation;

[0031] (2) Put the selected parent-ginseng into the parent-ginseng cultivation pool, and then stimulate the parent-ginseng to discharge sperm eggs by raising the temperature. The heating process is an equal gradient temperature increase, that is: the initial temperature is 15.5°C, the end temperature is 22.5°C, and the heating rate is 1 °C / day; after the tempe...

Embodiment 2

[0036] (1) From March 10th to 15th, 2009, mature individuals of sea cucumbers grown in sea areas for two years were selected from Nanri Island, Fujian Province, and Dalian, Liaoning Province as parent ginseng (50% of which were collected from Nanri Island sea area of ​​Fujian Province and grown 2-year-old mature sea cucumber individuals, 50% of which are collected from mature sea cucumber individuals grown for 2 years in the sea area of ​​Dalian, Liaoning). The ginseng was transported to the Huayang Sea Treasure Seed Breeding Field in Xiuyu District, Putian City, Fujian Province by means of low-temperature and wet transportation;

[0037] (2) Put the selected parent-ginseng into the parent-ginseng cultivation pool, and then stimulate the parent-ginseng to discharge sperm eggs by raising the temperature. The heating process is an equal gradient temperature increase, that is: the initial temperature is 15.5°C, the end temperature is 22.5°C, and the heating rate is 1 °C / day; afte...

Embodiment 3

[0042] (1) From March 5th to 10th, 2010, mature individuals of sea cucumbers grown in the sea area for two years were selected from Nanri Island, Fujian Province and Qingdao, Shandong Province as parent ginseng (50% of which were grown in the sea area of ​​Nanri Island, Fujian Province) 2-year-old mature sea cucumber individuals, 50% of which are collected from mature sea cucumber individuals grown for 2 years in the sea area of ​​Qingdao, Shandong). The ginseng was transported to the Pengfei Seafood Seed Breeding Farm in Xiuyu District, Putian City, Fujian Province by means of low-temperature and wet transportation;

[0043] (2) Put the selected parent-ginseng into the parent-ginseng cultivation pool, and then stimulate the parent-ginseng to discharge sperm eggs by raising the temperature. The heating process is an equal gradient temperature increase, that is: the initial temperature is 15.5°C, the end temperature is 22.5°C, and the heating rate is 1 °C / day; after the tempera...

Abstract

The invention provides a method for scale breeding of south-migrated stichopus japonicus. The method comprises the steps: selecting mature individuals, which grow for two years in a coastal area, as parental stichopus japonicus, putting the selected parental stichopus japonicus into a breeding pond, and then, stimulating the parental stichopus japonicus to liberate sperms and ova through heating; removing excess male parental stichopus japonicus after heating is ended, then, washing zygotes in the parental stichopus japonicus breeding pond, and hatching in the pond, so as to obtain juvenile; siphoning the juvenile, which moves agilely in an upper layer of water of the breeding pond, to a juvenile breeding pond for juvenile breeding, so as to obtain juvenile stichopus japonicus; attaching the juvenile stichopus japonicus to an attachment device, and suspending the stringed attachment device into a juvenile stichopus japonicus breeding pond, where impurities are discharged, for juvenile stichopus japonicus breeding. According to the method, the problems of high cultivation cost and high death rate caused due to the fact that a large amount of stichopus japonicus seedlings are purchased from the north can be avoided, so that the method provided by the invention is applied to the scale breeding of the south-migrated stichopus japonicus which is suitable for Fujian and neighboring regions thereof.

Description

【Technical field】 [0001] The invention belongs to the field of aquaculture, and in particular relates to a large-scale breeding method for southward sea cucumbers. 【Background technique】 [0002] Sea cucumber is regarded as a good food supplement and a tonic for physical fitness, and has now formed a consumer market centered on China, Hong Kong, Japan, South Korea, and the United States. The sea cucumber (Stichopus japonicus), which is native to the coast of the Yellow Sea and the Bohai Sea in my country, has a particularly prominent role in health care and has broad development prospects; the sea cucumber breeding industry is not only the pillar industry of the coastal aquatic industry in the north of my country, but also a major industry in the south coast of my country. An emerging aquaculture industry. In recent years, Fujian, as one of the large marine provinces in southern my country, has also made great progress in the cultivation of sea cucumbers, forming pond cultur...
