Problems solved by technology

But at present, the feed problem of sea cucumber farming has not been completely solved. For example, direct use of kelp will cause difficulty in digestion of sea cucumbers and lack of proper proportion of cellulose, which will easily lead to poor growth.
At present, Sarga

Embodiment 1

[0024] The float 1 of the sargassum culture device adopts a round orange plastic float with a diameter of 0.20-0.28m, and is connected with the float frame 3 through the float tether 2. Floating on the surface, once the device is prolonged, it is manually lifted to the surface.

[0025] The 4 corners of the floating frame 3 hang the falling stones through the tethers 6 of the falling stones with a length of 0.5 meters. The falling stones 7 adopt 5 kg rocks or concrete blocks. After the floating frame 3 sinks, it can be suspended in the water layer 0.5 meters above the seabed middle.

[0026] The floating frame 3 is a rectangular structure, the four frames have a side length of 3.0m and a width of 2.0m, adopt PPR cold water pipes with a diameter of 90mm and a thickness of 8mm, and adopt PPR straight-through elbows with the same diameter. Apply hot melt welding. That is to say, each floating frame is composed of two 2m PPR pipes, two 3m PPR pipes and four elbows. The maximum b...

Abstract

The invention aims to provide a method and a device for co-cultivating gulfweed and sea cucumber. The device provided by the invention comprises a floating frame serving as a main body and seedling ropes fixed on the floating frame and is characterized in that the floating frame is connected with dropstones for making the floating frame sink down through tying ropes; the specific gravity of materials of the floating frame is not greater than that of seawater. The device provided by the invention is used for cultivating the gulfweed, feeding the gulfweed into a sea cucumber cultivation sea area and co-cultivating the gulfweed and the sea cucumber; through the co-cultivation of the gulfweed and the sea cucumber, the gulfweed can grow efficiently and is used as sea cucumber feeds; and therefore, the device has the advantages of small investment, simplicity in operation and high economical benefit. According to the method provided by the invention, the labor for cultivating the gulfweed and breeding the sea cucumber is reduced, and the contradiction in a space distance that the sea cucumber suitable for demersal living and the gulfweed suitable for overwater living serve as feeds is solved, and the contradiction in time that the gulfweed grows in the day and serves as the feeds at night is solved. The method is small in investment, easy to operate and higher in economical benefit and has a popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of aquaculture methods, and in particular relates to a method and a device for co-cultivating sargassum and sea cucumbers. Background technique [0002] Sea cucumber, as a rare aquaculture product, has high added value, and has a large market demand and good economic value. Sea cucumbers live at the bottom of the sea, and their main food is single-celled algae, organic debris, seaweed fragments, bacteria and humus in sea mud. However, the problem of feed for sea cucumber cultivation has not been completely resolved at present. For example, direct use of kelp will cause difficulty in digestion of sea cucumbers and lack of proper proportion of cellulose, which will easily lead to poor growth. At present, Sargasso algae and other Sargassum algae are used more as feed, but the large-scale cultivation technology of Sargassum algae has not been solved, and there is a situation that the supply exceeds demand, and ...
