Plug-in artificial algal reef and method for constructing algal field by using same

Abstract

The invention discloses a plug-in artificial algal reef and a method for constructing an algal field by using the same. The algal reef comprises a solid base and an attached block movably connected to the solid base through a connecting rod, wherein the attached block is semispherical and has a rough surface, thereby meeting the requirement for the attachment of algae germ cells; and both the solid base and the attached block can be formed by one-step concrete pouring. When the algal field is constructed, the solid base is put into the sea and is soaked for a period of time; meanwhile, the attached block is dipped into seawater containing algae germ cells, and the attached block subjected to species introduction is movably connected to the solid base through the connecting rod after the algae germ cells are attached to the attached block. The plug-in artificial algal reef is convenient to use and is firm and durable, and algae can be prepositively fixed on the attached block so that germ cells diffused by algae sporophytes continue growing on the solid base; the germ cells is prevented from being swallowed by natural enemies, and the success rate of algae introduction is increased; the rehabilitation of the algal field can be realized, and a foundation is laid for building a new algal field.

Description

technical field [0001] The invention relates to an artificial algae reef, in particular to a plug-in artificial algae reef and a method for constructing an algae field, which is suitable for production as an attachment base for algae. Background technique [0002] As primary producers in the ocean, seaweed plays a role in stabilizing and restoring the marine ecological environment. Under the background of accelerating ocean development and utilization, over-exploitation of marine resources, and increasingly serious marine pollution, algae farms are degrading in some sea areas. How to restore the damaged algae fields in these natural sea areas is imminent. At the same time, under the new marine aquaculture environment, the construction of algal farms is also a very important issue. In the life history of seaweed, there are processes in which sporophytes release germ cells, attach germ cells and then germinate. In this process, a good attachment base is the key to whether t...

AI Technical Summary

Problems solved by technology

Ubiquitous shortcomings such as lack of design or unreasonable design, simple production, weak seaweed adhesion and too bulky

Specifically, there are the following deficiencies: one is the lack of seawater storm-proof design, which will make the algae reefs put in are vulnerable to wind and waves, so that the germ cells of seaweed cannot be firmly attached, reducing the success rate of seaweed introduction

The second is the lack of design to prevent algae predators such as sea urchins

The third is that the designed algae reefs are not mobile, and are often too heavy to carry out the operation of introducing algae, and the seabed sediment is easy to cover them

[0004] The reason for the above problems or deficiencies is that, first of all, in actual production, based on the consideration of convenience and cost reduction, waste is simply utilized, and the natural characteristics of algae attachment are used to put in algae reefs.

Secondly, the design of artificial algae reefs in the prior art may be inconsiderate, and various problems will inevitably arise when it is applied to actual production
