Breeding device and method for polyculture of marsupenaeus japonicus and sea grapes

Abstract

The invention discloses a breeding device for polyculture of marsupenaeus japonicus and sea grapes and a breeding method adopting the device. The device comprises a breeding pond, sand is laid on thebottom of the breeding pond, and a plurality of sea grape breeding devices, a plurality of nano oxygenation devices and a water outlet are arranged on the bottom of the breeding pond; and a rope is arranged above the breeding pond, the sea grape breeding devices are connected with the rope through a lifting rope, a floater is arranged on the lifting rope, and a valve is arranged on the water outlet. According to biological characteristics of the marsupenaeus japonicus and the sea grapes, the curved-surface sea grape breeding devices are applied to inoculate the sea grapes, the three-dimensional structure of the curved-surface sea grape breeding devices effectively widens the breeding space of the sea grapes, the growth range of the sea grapes is widened, a good hiding environment is provided for the marsupenaeus japonicus, and the survival rate and the breeding yield of the marsupenaeus japonicus are increased. The breeding device is easy to operate, low in breeding cost, capable of saving bait, good in breeding benefit, suitable for breeding in soil ponds, mulching film breeding ponds and indoor workshops, capable of being popularized in a large range and high in practical value and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of water body culture, in particular to a culture device and method for polyculture of Penaeus japonicus and sea grape. Background technique [0002] Marsupenaeus japonicus, also known as Kuruma prawn, also known as flower shrimp, is native to Japan, China, the Philippines, Australia and other countries, and is one of the important marine cultured species in my country. Because of its delicious meat, strong stress resistance, and suitable for long-distance dry dew transportation, it is deeply loved by shrimp farmers and consumers. In 2018 alone, the aquaculture output of Penaeus japonicus reached 55,228 tons, bringing huge economic benefits to coastal farmers. Due to its cannibalism and sand-burrowing habits, Penaeus japonicus is currently mainly cultured in low-density ponds or mulched with sand, and its aquaculture output is also limited. Therefore, it is imperative to invent a culture device and a metho...

AI Technical Summary

Problems solved by technology

The artificial propagation of sea grapes originated in Japan, and its breeding market prospects are very broad. However, due to the high requirements of sea grapes on the growth environment and water quality, artificial breeding is relatively difficult.

At present, the culture mode of sea grapes is relatively simple, and there are no reports and examples about the polyculture of sea grapes and Penaeus japonicus in production
