Embodiment 1

[0038] The experiment time is from October 23, 2010 to July 30, 2011. The test site is the sea area of ​​Lidao in Rongcheng City. The water depth of the aquaculture area is 25m, the transparency is 10m, the maximum flow rate is 50cm / s, no industrial and domestic sewage is injected, the annual surface water temperature changes in the range of 3~23℃, the salinity is 28.5~32.1, pH=7.01~9.74, which belongs to the national fishery water quality standard ( I) Class. Use the above-mentioned macroalgae deep-water composite space cultivation facilities and methods for cultivation, such as figure 1 As shown, the surface raft culture device and the middle vertical culture device are each equipped with 50 rows of floats, the spacing between the rows is 4m, and each row has 10 plastic floats2, the float spacing is 3-5m, and the floats 2 With a middle through hole 9, such as figure 2 As shown, the hanging rope on the surface raft culture device is 5-7m long, so that the suspended scallops ...

Embodiment 2

[0042] The experiment time is from October 24, 2010 to July 30, 2011. The test site is the sea area of ​​Zhangzi Island in Dalian. The water depth of the aquaculture area is 30m, the transparency is 11m, the maximum flow rate is 55cm / s, no industrial and domestic sewage is injected, the annual surface water temperature changes in the range of -1.0~24℃, the salinity is 29.5~33, and the pH=7.30~8.30, which belongs to the national fishery water quality standard (I) Class. The cultivation method adopts the above-mentioned macroalgae deep-water composite space cultivation technology. The surface raft-type cultivation device and the middle-layer vertical cultivation device are each equipped with 100 rows of floating nets. The spacing between rows is 3.5m, and each row has 30 plastic floating buckets. The distance between the buckets is 3-5m, and the floating bucket has a central through hole. The hanging rope 3 on the surface raft-type breeding device is 5-7m long, so that the suspe...

Abstract

The invention relates to kelp deep-water composite space culture facility, which consists of a surface-layer raft-type culture device and a middle-layer vertical culture device; the surface-layer raft-type culture device is connected with the middle-layer vertical culture device through a connection rope between an upper floating rope and a lower floating rope, one end of the connection rope is fixedly connected onto the floating rope of the middle-layer vertical culture device, the other end of the connection rope passes through a middle through hole in an upper floater of the surface-layer raft-type culture device to be fixedly connected onto the floating rope of the surface-layer raft-type culture device, the connection rope is arranged on the floating rope and is provided with a residual end, shellfishes are hung onto the floating rope, when the floating rope on the surface-layer raft-type culture device is rotated, the connection rope is wound on the floating rope, and the residual end is fastened onto the connection rope to prevent the floating rope which is interwined with the connection rope from rotating in an opposite direction. By adopting the method, kelp and shellfish can be simultaneously cultured in deep sea area, the culture water layer can be greatly adjusted according to the variation of the season and the water parameters, so the growth period can be prolonged, higher economic benefit can be obtained, and important significance on developing the kelp culture in China and improving the offshore area ecological environment can be realized.

Description

Technical field: [0001] The invention relates to an aquaculture equipment, in particular to a macroalgae deep-water composite space breeding facility and a breeding method thereof. Background technique: [0002] Macroalgae resources are of great significance in ecological environment, chemical industry, energy, food, medicine, etc. The basic biology research, seedling cultivation and breeding technology of macroalgae have received more and more attention. The research on macroalgae breeding technology will play an important role in enriching my country's marine aquatic resources, improving the marine environment, developing my country's marine aquaculture and breeding, and even promoting the entire aquaculture industry. [0003] There was no macroalgae distribution in China. In 1978, the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences successfully introduced a macroalga (Macrocystis pyrifera) larvae and gametophytes from Mexico by using low-tempe...
