Method of quickly building ecological oyster reef

Abstract

The invention relates to a method of quickly building an ecological oyster reef. The method comprises making an ecological oyster reef body, ecologically and quantitatively acquiring young oysters, carrying out floating-type quick growth, releasing at fixed spots regularly and other steps. The design of the method herein is achieved using the features of oysters in attachment and metamorphosis stage, growth stage, and breeding stage according to the biological and ecological principles of the oysters. The ecological oyster reef herein is made with natural materials and is harmlessly degradable; the ecological oyster reef body has light self-weight, so that settling risk is reduced and fry attachment efficiency is high; the staged floating-type reel body means helps evidently increase the biomass quantity and brood amount of the oyster reef and evidently increase the fry abundance in the breeding stage and the expanding rate of the reef body. in a word, the ecological oyster reef builtvia the method herein has the advantages that the reef has good environmental friendliness and ecology, fry harvesting efficiency is high, and growth speed is high; the problems are solved that existing oyster reel materials have poor ecology and environmental friendliness, the reef body has low fry-acquiring efficiency, growth rate, survival rate and breeding efficiency, and oyster resource-deficient regions have difficulty of building oyster reefs.

Description

technical field [0001] The invention relates to an artificial reef construction technology, in particular to a method for rapid construction of an ecological oyster reef. Background technique [0002] Oyster reefs are an important component of the marine ecosystem in the estuary area, which can limit the bloom of planktonic algae and the process of water eutrophication, provide refuge, feeding or breeding places for many important economic animals, and have important fishery value. In addition, oyster reefs have important functions in purifying water bodies, green governance, providing habitats, promoting fishery production, and enriching biodiversity. Its role is comparable to that of coral reefs in tropical areas. More than 85% of the world's oyster reefs have been lost in recent centuries due to overharvesting, pollution and climate change. Since the mid-20th century, oyster reef reconstruction projects have been carried out in Maryland, Virginia, and Australia. In rece...

Problems solved by technology

[0004] The present invention aims at the problems of poor eco-environmental protection of current oyster reef materials, low seedling collection efficiency, growth, survival and reproduction efficiency of reef bodies, and difficulty in building oyster reefs in areas where oyster resources are scarce. Reef construction, seed ecological quantitative collection, reef floating rapid growth and fixed-point delivery technology provide a method for rapid construction of ecological oyster reefs. The steps include:
