Description
Technical field:
The present invention relates to a kind of macro aquaculture facility that is applicable to opening deep water sea area, be specially the floating bed of a kind of adjustable deep-sea algae aquaculture.
Background technology:
The marine site of China's mariculture utilization mainly concentrates in 20 meters isobaths.The zone that surpasses 20 meters depth of waters is because far away apart from bank, and it is less therefore influenced by pollution from land-based sources, and current are unimpeded, and water quality is pure and fresh, is to carry out the important area that repair in the habitat, shallow sea and fishery resources are recovered.The structure of tangleweed bed is the key of repairing habitat, impaired ocean, the efficient recovery fishery resources being arranged.The neritic province domain macro adopts the raft culture mode more; Its advantage is a convenient management, but shortcoming is that the right sea area depth of water of supporting is more shallow, cultures algae and occupy the upper strata water body; When running into exceedingly odious weather (like typhoon); Raft frame and seedling rope is influenced by stormy waves can strenuous exercise, tangle, and causes algae to come off in a large number, therefore can't use in the anxious deep water sea area of stream in that the wave is high.And the growing requirements of macro can't be satisfied because illumination is not enough in the seabed of deep water sea area, has limited the structure of kelp bed.Therefore, being necessary to develop a kind of macro aquaculture facility that is applicable to opening deep water sea area, is that macro provides good growth platform in wide deepwater regions, for the habitat reparation and the fishery resources in off-lying sea marine site recover to provide equipment to support.
Summary of the invention:
The present invention provides the design of the floating bed of a kind of adjustable deep-sea algae aquaculture, to solve the difficult problem that deep water sea area can't carry out the macro aquaculture.Using this facility can carry out the macro aquaculture in the marine site of the depth of water more than 20 meters, and algae can avoid the influence of off-lying sea severe sea condition simultaneously at suitable water growth layer.This facility also can be used as the aquaculture platform of precious marine products such as Bao, stichopus japonicus.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
