Reef used for seed fixation and germination and seedling growth of shrimp seaweed

Abstract

The invention provides a reef used for seed fixation and germination and seedling growth of shrimp seaweed. The reef comprises a reef body with a cuboid shape, wherein the upper surface of the reef body is provided with a groove; two opposite side surfaces of the reef body each are provided with through holes; all through holes do not communicate with the groove; stainless steel wires vertical tothe groove are uniformly distributed on the groove located at the top part of the reef body; each stainless steel wire has a diameter of 3 mm and a length of no less than 8 mm; the design of the reeffacilitates fixation of shrimp seaweed seeds; the groove is an inverted quadrangular frustum pyramid-shaped groove; the distance between every two stainless steel wires is 4 to 5 mm; two above-mentioned opposite side surfaces of the reef body are also provided with blind holes; all blind holes do not communicate with the inverted quadrangular frustum pyramid-shaped groove; and the through holes and the blind holes are of a cylindrical shape, are the same in diameter and are mutually parallel. The reef provided by the invention has the advantages of simple structure, low cost, less material consumption, easy throwing, and high shrimp seaweed seed retaining efficiency, and has important significance for large-scale transplantation of the shrimp seaweed and restoration of a damaged seaweed farm in future.

Description

technical field [0001] The invention relates to a device for protecting the seabed ecological environment, in particular to a reef body for fixation, germination and seedling growth of shrimp seaweed seeds. Background technique [0002] Seagrass is the only higher plant in the ocean. It can not only directly provide high primary productivity, but also serve as the attachment base for other epiphytic algae and other marine animals to lay eggs, which is of great significance to the ecological environment of coastal marine fisheries. . Shrimp seagrass is widely distributed on the coastal reefs of the North Pacific Ocean and is an important seagrass species that constitutes the coastal ecosystem. The Shrimp Sea Grassland used to be one of the most important ecosystems in northern my country, especially the Shandong Peninsula. It was the spawning ground, feeding ground and nursery ground for many important economic fish. It used to be a traditional dwelling along the northern co...

AI Technical Summary

Problems solved by technology

And when there is no suitable seaweed growth on the rocky bottom, the shrimp seagrass seeds cannot be fixed even if they spread to this area, so that the natural construction of shrimp seagrass beds cannot be realized in this area

This situation means that once the shrimp seagrass bed is destroyed, it will be a very long process to achieve natural recovery
