Problems solved by technology

However, these methods of fertilizing water have many defects. One, fertilizing ponds is time-consuming and laborious; two, the relationship between bait organisms and the number of jellyfish cannot be controlled. If the fertilizer and water are too large, the water body will be polluted, affecting the growth of jellyfish. The demand for bait, jellyfish growth is slow or even negative growth

Embodiment 1

[0011] At the end of May 2018, in a breeding company in Dongtai, Jiangsu Province, a breeding pond with an area of ​​500 mu was selected as a jellyfish breeding pond. The depth of the pond was 3m, and the bottom of the pond was sandy and muddy, flat and free of obstacles. Next to the jellyfish pond, dig 5 ponds with a single area of ​​20 mu and a depth of 2.5m. Each pond is close to the jellyfish breeding pond, so that the pond water rich in small plankton can be introduced into the jellyfish breeding pond by siphoning. Dig pits at the four corners of the bait culture pond, bury chicken manure, cover with plastic film, ferment for more than 1 month, and sprinkle fermented chicken manure as base fertilizer, with an amount of 600kg / mu. Five bait culture ponds were first inoculated with rotifers every other day, so that the peak periods of rotifers in the five ponds were staggered. The rotifer inoculation time was carried out 15 days before the jellyfish seedlings were stocked. ...

Embodiment 2

[0013] At the end of May 2019, in a breeding company in Sheyang, Jiangsu Province, a breeding pond with an area of ​​300 mu was selected as a jellyfish breeding pond. The depth of the pond was 3m, and the bottom of the pond was made of sand and flat without obstacles. Next to the jellyfish pond, dig 3 ponds with a single area of ​​20 mu and a depth of 2.5m. Each pond is adjacent to the jellyfish breeding pond, so that the pond water rich in small plankton can be introduced into the jellyfish breeding pond by siphoning. Dig pits at the four corners of the bait culture pond, bury chicken manure, cover with plastic film, ferment for more than 1 month, and sprinkle fermented chicken manure as base fertilizer, with an amount of 700kg / mu. Three bait culture ponds were first inoculated with rotifers every other day, so as to stagger the peak period of rotifers in the three ponds. The rotifer inoculation time was carried out 15 days before the jellyfish seedlings were stocked. Jellyf...

Abstract

The invention discloses a method for breeding jellyfishes by culturing small zooplanktons. The method is characterized in that a small zooplankton culture pond is arranged beside a jellyfish breedingpond, the total area of the small zooplankton culture pond accounts for 1 / 6-1 / 3 of that of the jellyfish breeding pond, the small zooplankton culture pond is divided into 3-6 small zooplankton culturepond bodies, fermented chicken manure is splashed to each small zooplankton culture pond body to serve as base fertilizer according to the usage amount of 600-800kg / mu, and the small zooplanktons arecultured. The jellyfishes are fed by culturing and collecting the small zooplanktons, so that the quantity of the small zooplanktons in the jellyfish pond is kept at 2000 ind / m<3>-3000 ind / m<3>. According to the method, the small zooplanktons in the jellyfish breeding pond are kept within a reasonable and controllable range, so that the jellyfish quantity and the bait organism quantity reach dynamic balance.

Description

technical field [0001] The invention belongs to the field of aquatic animal breeding, and in particular relates to a method for cultivating jellyfish by cultivating small zooplankton, so that the small zooplankton in jellyfish breeding ponds can be kept within a reasonable and controllable range. Background technique [0002] Jellyfish is a large edible jellyfish. Widely distributed in the four sea areas of our country, it has high nutritional value and economic value. In recent years, due to the continuous expansion of the demand for jellyfish in domestic and foreign markets, the price of jellyfish has continued to rise, which has induced the scale of jellyfish farming to continue to expand. With the expansion of the scale of jellyfish farming, problems in jellyfish farming have also followed. Feed problem has just become the important bottleneck that seriously restricts the further development of jellyfish breeding industry. [0003] In the process of jellyfish breeding,...
