Alga increment raft frame

Abstract

The invention discloses an alga increment raft frame. The alga increment raft frame is characterized in that the two ends of a floating rope are connected with one end of an anchor cable, the other end of the anchor cable is connected with sunken stones, the floating rope is connected with one ends of hanging ropes at intervals, alga attachment devices are arranged on the hanging ropes at intervals, the other ends of the hanging ropes are connected with hanging stones, the alga attachment devices are spherical, thorn-shaped protrusions are arranged on the surfaces of the spheres, special rough structures are formed on the surfaces of the thorn-shaped protrusions so that alga spores can easily attach to the thorn-shaped protrusions, and the alga spores can attach firmly after growing into algae and are not likely to fall off; when the algae are mature and fall off, diatom and other small organisms attached to the algae fall to the sea floor, natural food is provided for sea cucumber, new spores will attach to and germinate on the surfaces of the vacated attachment devices, a new crop of algae can occur in the next growth season, the attachment devices are repeatedly used, fresh and living algae are continuously provided, and the raft frame has the advantages of being good in increment effect, low in cost, capable of being used for a long time and good in ecological effect, not influencing landscapes and the like.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a seaweed value-added raft which can increase the output of seaweed and is especially suitable for sea cucumber cultivation sea areas. Background technique [0002] As we all know, sea cucumber fragments, diatoms and microorganisms are the main food of sea cucumbers. Macroalgae not only provide food for sea cucumbers, but also provide attachment and habitat for tiny diatoms and microorganisms, as well as ecological effects such as improving the environment. At present, in shallow sea areas where artificial methods are used to throw rocks and build artificial reefs for sea cucumber bottom-seeding cultivation, there is a common dilemma of insufficient natural bait for sea cucumbers. Especially in the deep area where the stone is thrown below 10 meters, due to factors such as insufficient light at the depth of the water, the surface of the thrown stone is occupie...

Problems solved by technology

At present, in shallow sea areas where artificial methods are used to cast stones and artificial reefs are used to cultivate sea cucumbers at the bottom of the sea, there is generally a predicament of insufficient natural bait for sea cucumbers

Especially in the deep area below 10 meters, due to factors such as insufficient light in the depth of the water, the surface of the thrown stones is occupied by benthic animals such as sponges, so that seaweed rarely grows, and the problem of insufficient bait for sea cucumbers is more prominent. Now artificial Feeding sage algae or feeding other brown algae into pulverized liquid, the deficiencies of the prior art are the high cost of manual harvesting, crushing, processing and feeding of seaweed; the second is that harvesting seaweed puts pressure on natural resources; The ecological effect of seaweed cannot be exerted
