Summary of the invention
The present invention provides three kinds to be master's technology to control imitative apostichopus japonicus culture pond macro excessive multiplication for solving dwell at the bottom of the imitative apostichopus japonicus culture pond existing control technology of macro and the problem that method exists, and specifically solution is following:
1, complex culture macro asparagus is controlled the dwell excessive multiplication asparagus (Gracilaria lemaneiformis) of macro of the end through the mode of shading and is the large-scale red algae of Gracilaria, has comfort zone wide (5~27 ℃); The righttest growth water layer is 0.5m-1m, and the sea water specific gravity of right growth is 1.018~1.022, and accommodative ability of environment is strong; Growth is fast, anti-dense planting, and gel content is high; The original producton location is in Shandong Province and Liaoning Province, after be transplanted to south.Asparagus both can be used as bait and the feedstuff of some breed varieties such as abalone, also can be used as the raw material of producing agar, had favorable economic benefit.Asparagus also has higher absorption ratio and removes efficient ammonia nitrogen, removes NH in the cultivating system 4-N and PO 4The amount of-P can both reach more than 50%.
Annual spring; Suspended longline farming macro asparagus in the imitative apostichopus japonicus culture pond; Played the effect of shading on the one hand; Make benthic algae spore germination, adhere to and growth is restricted, absorbed the nutritive salt in the breeding water body on the other hand, can control the benthic algae breeding and the growth in imitative apostichopus japonicus culture pond effectively.Simultaneously can also promote photosynthesis, increase the pond oxygen in water, help improving the breeding environment of imitative stichopus japonicus growth.The benefit of suspended longline farming macro can in time be gathered on the one hand, can select the kind of economic worth on the other hand, like asparagus.
2, the good mud of suspension of splashing, the mode that reduces the breeding water transparency are controlled the dwell breeding of macro of the end
The change in time and space of seawater transparency receives influence of various factors, and wherein the composition of suspension and content are the principal elements that influences transparency in the seawater.Seawater transparency is represented the transmission depth of light in seawater; Its size be with seawater and wherein suspended material the absorption that is transmitted into marine light and the difference of scattering effect are changed, so the composition of suspended material and content greatly affect the transparency change of seawater.The settling velocity of suspended particulate is relevant with particle diameter, density, shape and surface roughness, and is also closely related with the temperature of seawater, salinity etc. simultaneously.
In spring benthic algae spore germination and setting stage; Through changing water, the suitable mud (mud particle average median particle diameter 1-5um) of splashing; Reduce the transparency of breeding water body, according to the depth of water of cultivating pool, make transparency be reduced to the water surface following at the bottom of the pond height 10-20cm; If i.e. breeding water body mean depth of water 100cm, then transparency should be no more than 90cm.Make the end macro of dwelling to obtain the illumination of continuous and effective, the dwell breeding of macro of the control end.
3, utilize shading screen to regulate illumination, the dwell breeding of harmful algae of the control end
For small-sized cultivating pool (about 10 mu), also can be through shading on the cultivating pool surface with shading screen, the intensity of control illumination makes illumination can not reach the bottom of cultivating pool, and harmful algae is dwelt at the end can not excessive multiplication.
