Embodiment 1

[0029] The present invention will be further described below in conjunction with practical examples.

[0030] The present invention proposes the regulation and control technology of jellyfish polyp multi-crop transverse fission reproduction, and the application of the water temperature and bait amount regulation technology proposed by the present invention can make the number of disc-shaped larvae released by the same amount of jellyfish polyp increase by 2 to 5 times. To achieve the purpose of efficient utilization and improving the economic benefits of breeding, the technical method widely used in China (1°C or 2°C per day) and the control method of the present invention (10°C low temperature period below 10°C are slowly increased by 0.5 to 1°C per week) are briefly described below. ℃, in the range of 10-15 ℃, slowly increase 1-2 ℃ every week, then increase 2 ℃ every two weeks, and keep the water temperature at 19 ℃).

Abstract

The invention discloses a method for regulating rhopilema esculentum kishinouye scyphistoma multi-crop strobilation, and belongs to the technical field of aquatic animal breeding. By controlling the water temperature at 15-19 DEG C and the feed amount, rhopilema esculentum kishinouye scyphistoma is subjected to repeated strobilation so that the total number of ephyrae released by the same amount of scyphistoma is increased by 2-5 times. The method can effectively increase the utilization rate of rhopilema esculentum kishinouye scyphistoma fry, that is, the number of the rhopilema esculentum kishinouye scyphistoma fry can be increased in a short period, the problem that the fry are out of season in a multi-crop breeding mode and accordingly the fry are insufficient in supply is also solved,the production cost is reduced, rhopilema esculentum kishinouye fry breeding efficiency and economic benefits of rhopilema esculentum kishinouye breeding are greatly improved, the control technologyis simple, and the method is suitable for wide popularization.

Description

technical field [0001] The invention relates to a technique for regulating and controlling the multi-crop transverse reproduction of jellyfish polyp, which belongs to the technical field of aquatic animal breeding, and specifically relates to a jellyfish polyp repeated transverse reproduction culture mode, so as to improve the efficiency of jellyfish seedling cultivation and improve the quality of jellyfish Economic benefits of farming. Background technique [0002] The large edible jellyfish jellyfish (Rhopilema esculentum Kishinouye) belongs to the coelenterata (Coelenterata), bowl jellyfish (Scyphomedusae), root mouth jellyfish (Rhizostomeae), root mouth jellyfish (Rhizostoidae), jellyfish (Rhopilema), is the growth in the ocean Zhongying is a large-scale warm-water jellyfish living in planktonic life, which is abundant in the inland seas and coastal areas of the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Jellyfish has become a delicacy on Chinese banque...
