Sea-in forest oviposition protection reef

Abstract

The present invention discloses a sea-in forest oviposition protection reef. The sea-in forest oviposition protection reef comprises a main skeleton, an internal network connected with the main skeleton and an artificial simulated algae hung on the main skeleton and the internal network, wherein the main skeleton is formed by welding reinforcing steel bars; and the internal network is formed by mutually cross binding of the reinforcing steel bars or first ropes. The sea-in forest oviposition protection reef can provide oviposition places for the reef fish, the migratory fish and the cephalopodium fish, and can provide privileged places for the larval and juvenile to relieve the current situation that repairing development of offshore algal fields is slow in our country.

Description

technical field [0001] The invention relates to the technical field of artificial fish reefs, in particular to a forest-in-the-sea spawning protective reef. Background technique [0002] The natural algae field in the ocean usually refers to the place where the water depth is less than 20m and where the seagrass or seaweed community grows luxuriantly. Natural algae fields provide living space for various marine organisms, especially in coastal waters, where algae fields are the spawning grounds for most rocky and migratory fish and cephalopods. However, since the 1970s and 1980s, the development of my country's coastal zone has gradually increased, and the pollution of the offshore marine environment and the degree of seabed desertification have become increasingly serious, resulting in a significant reduction in the area of ​​seabed algae fields, and the spawning of most traditional aquatic economic animals. The disappearance of the market has further exacerbated the extent...

However, since the 1970s and 1980s, the development of my country's coastal zone has gradually increased, and the pollution of the offshore marine environment and the degree of seabed desertification have become increasingly serious, resulting in a significant reduction in the area of ​​seabed algae fields, and the spawning of most traditional aquatic economic animals. market no longer exists, which has further exacerbated the extent of the decline in offshore fishery resources

[0003] Although my country has invested a lot of manpower and material resources in artificial restoration and restoration of seaweed fields, such as putting artificial fish reefs and transplanting algae, the restoration and restoration of algae fields has had little effect for a long time

The main reason is that the turbidity of coastal seawater is high, and the surface of fish reefs or algae reefs cannot receive long-term effective irradiation of the light layer, resulting in limited germination of algal spores attached to the surface of reefs. The effect is also mixed
