Gloiopeltis algae sea area breeding device and breeding method using same

Abstract

The invention discloses a gloiopeltis algae sea area breeding device which comprises a stereoscopic container made of a transparent material. The stereoscopic container is provided with at least two openings used as water exchange windows. Filtering screens are covered on the water exchange windows. The stereoscopic container is also provided with an openable inlet and outlet port for taking and placing seedlings. The invention also discloses a breeding method using the breeding device. The breeding device disclosed by the invention has excellent light transmission and water exchange rate andis beneficial to growth of algae. Not only can the breeding device be used for avoiding predator animals such as fishes and sea snails, but also the sea area breeding can be developed as soon as possible by the breeding device and does not need to be carried out when the algae sufficiently grows to clamp seedling ropes, and thus, the breeding period is sufficiently utilized and the development ofa gloiopeltis algae sea area breeding technology is promoted.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a device for cultivating seaweeds of the genus Diana, and a method for cultivating using the device. Background technique [0002] Seaweed is a red algae with high economic value (its dry product reaches 800 yuan / kg). It can be used as food, medicine (with anti-tumor functions), and can be used as industrial raw materials. [0003] At present, the amount of seaweed resources is decreasing day by day, and the market demand is increasing day by day, resulting in a situation where the supply of seaweed is in short supply. Therefore, it is inevitable to develop the cultivation technology of seaweed. However, the existing seaweed cultivation adopts the method of natural multiplication on reefs in sea areas, and the output of this cultivation method is limited, and the output is gradually declining, so that it cannot meet the demand of the market. [0004] The technical difficulty of seawee...

AI Technical Summary

Problems solved by technology

The growth of seaweed is suitable for water temperature below 23 ℃, and the period suitable for the growth of seaweed is very short every year, especially in the south. The period suitable for the growth of seaweed is even shorter. Newly grown larvae of seaweed can be seen around the month, but in March, when the temperature is slightly higher, the algae growing at higher tidal levels begin to rot

[0005] In addition, the algae of the seaweed genus are small. Although the algae fragments can continue to grow, the general seaweed raft culture method (that is, the algae are broken into seedlings and then clamped on the rope) is used to carry out the growth. The production efficiency of sea area farming is relatively low, which is also the technical difficulty of its farming

The existing method of cultivating seedlings from spores for cultivation in sea areas can solve the source of seedlings required for cultivation, but it takes a lot of time to cultivate seedlings, and the seedling cultivation technology is still immature and is only in the initial stage of application. stage

[0006] To sum up, the above factors all limit the development of the cultivation technology of the genus Pyramid in the sea area, and it is imperative to develop new technologies for the cultivation of the genus Pygnus in the sea area
