Ecological remediation type marine ranch and construction method for same

Abstract

The invention discloses an ecological remediation type marine ranch and a construction method for the same, and belongs to the technical field of marine ecological environments. The marine ranch comprises more than one multifunctional unit culture platform, wherein each multifunctional unit culture platform comprises a lifting and submersible ecological unit culture platform frame consisting of a U-shaped main floating pipe and more than one HDPE (High-Density Polyethylene) junction pipe; the two ends of each U-shaped main floating pipe are closed, and each U-shaped main floating pipe is formed by bending a large-diameter HDPE pipe; the two ends of each HDPE junction pipe are closed; alga bed areas, open box type precious marine product polyculture areas, settlement devices and anchorage devices are arranged on the platform frames. According to the marine ranch and the construction method, the multifunctional unit culture platforms have a lifting function, and can float to the water surface and stay in different underwater layers, so that the photosynthesis of algae is facilitated, and high growth speed is ensured; by the open box type ecological polyculture of precious marine products such as algae, abalones, cucumbers, oysters and mytilidae, a marine resource remediation function is realized, and good ecological benefits and economic benefits are created.

Description

technical field [0001] The invention relates to an ecological restoration type marine pasture and a construction method thereof, belonging to the technical field of marine ecological environment. Background technique [0002] As the pressure and influence exerted by humans on the ocean continue to increase, it has directly or indirectly led to serious degradation of the marine ecosystem. In particular, the excessive, disorderly and irresponsible development and utilization of the ocean has accelerated the degradation of the marine ecological environment and led to a serious decline in the function of the marine ecosystem. The "blue granary" for human beings to provide food or protein guarantee is an ecological fishery development model. It subverts the traditional fishery production mode mainly based on fishing and facility breeding in the past, and overcomes the resource loss caused by overfishing. Depletion, seawater pollution and disease aggravation caused by offshore aq...

AI Technical Summary

Problems solved by technology

At present, my country's marine ranch construction is basically constructed according to this method, but it is found during the construction that due to the constraints of different sea bottom materials and water depths, such as the construction of artificial fish reefs, many small breeding reefs have been put into the seabed, and over time It is easy to sink in the mud due to the movement and wind, waves and currents; the cost of large-scale fish-accumulating reefs is high, and it is difficult to transport and hoist at sea; the algae reefs and stones placed in the algae farm restoration are greatly affected by the water depth, and the photosynthesis will be weakened if the water depth is too deep. The success rate of transplantation is extremely low, and the restoration of the algae field is slow, especially after the algae grow on the algae reef or stones, due to the small initial scale, they will soon be eaten by sea urchins and other harmful organisms, resulting in the entire army being wiped out
