Description
Technical field:
The present invention relates to a kind of bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt, specifically seawater bivalve shellfish, sea cucumber or the shellfish ginseng bottom-sowing type raft frame and the breeding cage of raising together with.
Background technology:
Current bivalve shellfish mainly contains two kinds of breed patterns such as raft culture and bottom sowing culture as shellfishes such as chlamys farreri, bay scallop or stichopus japonicus.The raft culture technology mainly is as floating well rope with a long rope, it is some large-scale cursory that floating well rope is provided with, floating well rope two ends are fixed on the seabed through the root rope by timber, floating well rope is floated in water, and floating well rope below hangs some breeding cages, and the shellfish or the ginseng class of breed is housed in the breeding cage, the major defect that this kind cultured pattern is: technology high temperature season disease takes place frequently, the aquaculture organism survival rate is low, and the capacity of anti-storm of structure is poor, and main culturing area concentrates on 20 meters isobaths with interior waters.The bottom sowing culture technology is directly to sow seed in the sea area, and this kind cultured the pattern seed and very easily met with harmful animal, and survival rate is low, and the recapture difficulty, and labour intensity is big, and the covering rate is low.
Summary of the invention:
In order to overcome existing raft culture and the deficiency of bottom sowing culture in shellfish, sea cucumber etc. are cultured, the invention provides a kind of bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt, this facility has been taken into account the advantage of raft culture and bottom sowing culture, weaken the influence of stormy waves to cultivating system, and can obviously reduce the influence of harmful organisms, convenient management and results.

The described bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt, etting material are polyethylene or can be compiled into net, seawater corrosion resistance, the material nontoxic to aquaculture organism for any in the prior art.
The described bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt, what fix this facility is timber or anchor, the material of timber or anchor is timber or anchor, or is any material that can be used for anchoring in the prior art; Timber or anchoring are on seabed or hermatolith.
The described bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt is fixed with rope on timber or anchor, the material of rope is a polythene material, or any material that can be used for making rope in the prior art.
The described bottom-sowing type water culture facilities that is applicable to marine site at the bottom of the silt, rope one end emerges, and is fixed with ball float, and ball float is bubbled through the water column; The material of ball float is a polypropylene material, or any material that can be used for making ball in the prior art.
The invention has the beneficial effects as follows:
1. take into account the advantage of raft culture and bottom sowing culture, the mentality of designing of the change tradition raft frame of novelty;
2. aquaculture organism becomes the end state of dwelling by suspended state, and the change in habitat is more suitable for scallop existence and growth;
3. strengthened the capacity of anti-storm of breeding facility, reduced the influence of natural calamity aquaculture;
4. reduce the invasion and attack of harmful organisms, increase scallop output;
5. cheap, easy and simple to handle, reduce labor intensity, be convenient to management and results;
6. weaken the influence of breed, help culturing the reparation and the comprehensive utilization of marine site ecotope the natural waters ecotope.
