Method for breeding jellyfishes by culturing small zooplanktons

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,...

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
