Artificial algae field and construction method thereof

Abstract

The invention relates to an artificial alga field and a construction method thereof. A regular polygon grid structure formed by ropes is taken as a unit grid; a heavy stone stabilizing the structure is arranged on each side of the unit grid, and at the equal-distant location of each side inside the unit grid, a crossed rope or a polygon structure is connected with other sides; marine alga is planted on the ropes to form a unit alga field; and a great many of such unit alga fields are woven by ropes to achieve a large area of artificial alga field. The invention is capable to construct an artificial alga field rapidly at low cost; as a result, the desertification of sea area is alleviated, the marine environment is purified, and a place for fish, shrimp and cuttle fish to spawn, seek food and inhabit is established, and the fishery resources are protected and increased; in addition, the artificial alga field can also be used to breed marine alga, and as a result, the income of fishermen is increased.

Description

Technical field [0001] The invention relates to an artificial algae field and a construction method thereof. Background technique [0002] In recent years, my country’s offshore marine fishery resources have been severely decayed due to overfishing, especially the bottom trawl fishing method, which has destroyed the original habitat of a large number of aquatic organisms, coupled with the rapid development of coastal aquaculture and a large number of land sources The discharge of pollutants has led to the destruction of seabed vegetation, the degree of desertification in the sea area has become more and more serious, the sustainable development of offshore marine fishery resources is also difficult, and the marine ecosystem is facing severe challenges. [0003] At present, an important method for restoring submarine vegetation at home and abroad is to afforest the seabed, that is, to build artificial algae farms. The algae field can fix nutrients and serve as a purification field...

AI Technical Summary

Problems solved by technology

An important means of building algae farms is to put artificial algae reefs on the seabed, that is, to put a large number of natural stones or artificial structures. Although the effect of this method of building artificial algae farms is good, it is restricted by many factors at the same time.

First, the construction of algae farms requires a large amount of algae reefs, that is, a large amount of stones, wood, steel, concrete, etc. The collection of these reef-building materials is also a kind of damage to the natural environment on land; the second is the process of transportation and release of algae reefs It is more complicated, labor-intensive, and costly, which is not conducive to promoting the development and implementation of artificial algae farm construction
