Composite seaweed farm in marine ranching area

Abstract

The invention relates to a composite seaweed farm in a marine ranching area and relates to the technical field of marine ecological breeding. The farm comprises a tower reef body put on the seabed, seaweed reef bodies uniformly distributed at the top end of the tower reef body, a long rope arranged above the seaweed reef body and a first buoy connected to the top end of the long rope through a pull rope, the long rope is used for attaching seaweed seedlings, and serves as a carrier for growth of seaweed , and the seaweed reef bodies are used for attaching the red algae plants and serve as the carrier for growth of the red algae plants. According to the farm, By cultivating macroalgae and red algae plants in the longitudinal space of the marine ranch, three-dimensional comprehensive utilization of the artificial fish reef area sea area can be achieved, the defects that a food net in marine ranch construction is simple in structure and low in nutrition level are overcome, the problem that the food net in the culture water area is single is effectively solved, the farm has positive significance on stable balance of offshore biological resource conservation and offshore biological diversity, and in addition, the convenience of picking cultured seaweeds is also improved.

Description

technical field [0001] The invention relates to the technical field of marine ecological breeding, in particular to a compound seaweed farm in a marine pasture area. Background technique [0002] my country has a long coastline of 18,000 kilometers, and its coastal waters are rich in marine resources. It is a key area for the development of my country's marine economy. In recent years, with the over-exploitation of marine resources and the impact of human activities, marine pollution has intensified, the marine ecological environment in offshore areas has been destroyed, biodiversity has decreased, the ecosystem of seaweed farms has continued to degrade, and water bodies have suffered from serious eutrophication, resulting in red tides, green Disasters such as tides occur frequently. As an important way to realize the harmonious development of fishery economy and offshore ecosystem, the construction of marine ranching has changed the previous fishery production mode that re...

AI Technical Summary

Problems solved by technology

[0003]Most of the construction of marine ranching is in the offshore area, and the relevant policies, foundations and means of marine ranching construction have become increasingly mature, but there are still some problems that need to be solved urgently, such as The structure of the food web is relatively simple, the trophic level is low, and the biological resources are not fully utilized. In addition, most of the plants cultivated in the sea need divers to pick them, which requires high technical requirements for divers, high labor intensity and low efficiency.
