Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of shellfish culture pond is spread cultivation system in situ with microalgae
And its application method.
Background technique
Pond culture is one of mode of sea-farming, because its breeding environment is relatively controllable, in recent years increasingly by blueness
It looks at, the more open breeding way of comprehensive economic benefit of aquaculture is greatly improved.But because of the difference of various regions environmental characteristic
The difference of different and leading breed variety, the type of different regions pond culture are also not quite similar, and in Deposits in Eastern Coastal China, open
The type cultivated in the property opened pond is mainly embedded type shellfish (based on razor clam of hanging, mud blood clam, clam etc.), and collocation is supported in the pond of part
Growing kind has the shell-fish such as Portunus trituberculatus Miers, Scylla paramamosain, occasionally there is the types such as exopalaemon carinicauda, Marsupenaeus japonicus.These aquaculture ponds
The pool is mainly by changing nature seawater or manually bait throwing in two ways increases the output capacity of aquaculture organism, and both modes
There is great limitation: firstly, increase the mode of output capacity by changing nature seawater is influenced by bait in changed water body
Obviously, if food organisms are not enriched in replaced water body, the bait of shellfish will be insufficient in that breeding water body, grows slow, warp
Benefit of helping is not high；Secondly, manually mode of the bait throwing in increase output is thrown mostly in the pond of crab class, shrimps and shellfish mixed breeding
Bait is for the growth of crab class and shrimps, and residual bait, excrement and the algae supply shellfish growth naturally bred, this mode will cause feeding
The pollution for growing water body, in the case where current environmental consciousness is increasingly enhanced, this mode is not suitable for large-scale promotion, and this
Food organisms are not also abundant enough in breeding way, and shellfish culture density should not be too high, influences yield.
The bivalve shellfish cultivated in pond is filter-feeding, their organic debrises and microalgae in water body of ingesting and give birth to
It is long.Therefore, in order to improve the environment in shellfish culture pond, accelerate the speed of shellfish growth or promote the production of shellfish culture in pond
Amount, except it is conventional change water and rich water technology in addition to, the output capacity for increasing pond by exogenous bait supply is more section
Approach, therefore the present invention is by some exogenous facilities, to realize the purpose for the pond production capacity for increasing cultivation.Mesh
Before, relevant report is had no for the mode of cultivating pool Culture in situ microalgae, has researcher to develop the photo-biological of microdisk electrode
Reactor, but there are some problems for these bioreactors, are not suitable for shellfish culture pond Culture in situ microalgae: first this
The volume of a little bioreactors is smaller, is only suitable for that small-scale microalgae spreads cultivation；Secondly microdisk electrode water is sand filtration seawater,
Another pond is needed to carry out water process；Third, microalgae supply is unsustainable, and only discontinuity is supplied, i.e. 1 pond of bioreactor culture is micro-
Algae carries out second of culture after needing to clean primary equipment again, time-consuming and laborious.Meanwhile during shellfish breeding, water is mostly used
Mud sump cultivates microalgae, but this training method facility degree requires height, and immovable, is not suitable for Culture in situ.This
Device realizes the in-situ batch culture of microalgae, is realized by picotan and is utilized using the original position of cultivating pool seawater, while is real
Primary culture, the lasting supply of microalgae are showed.

The method that system carries out microalgae Culture in situ 8. microalgae according to claim 7 spreads cultivation in situ, which is characterized in that packet
Include step in detail below:
(1) according to cultivating the difference of microalgae type, pre-configured algae spreads cultivation required culture solution, is contained in mother liquid multi-cavity bottle
In it is spare；
(2) spread cultivation algae in advance, is then transferred in reactor cabinet,
(3) seawater original position filter device is placed in the bottom of cultivating pool, by the natural pressure of seawater, seawater passes through bolting silk
After large-scale impurity is blocked in the first filtering of backstop, enter in water filtering tank from inlet, seawater is in drainage sponge along the bottom water fender I
End, the top water fender II are detoured after filtering, are flowed into spare in water storage box；
(4) power switch for starting lift pump, and opens the control valve on mother liquor extraction tube, by water storage box seawater and mother
Nutritive salt mother liquor in liquid bottle is pumped into reactor cabinet, and with the lasting injection of seawater and the amplification of frond, liquid level is more than algae
When hydrorrhea exports, the algae solution of amplification is injected into shellfish culture pond by algae discharge pipe, and supply shellfish ingests.
9. according to the method described in claim 8, it is characterized by: in step (2), initial stage spread cultivation algae when, algae liquid level is high
Degree is the 1/5 of reactor box height.
10. method according to claim 8 or claim 9, it is characterised in that: in step (4), adjust the flow rate switch on lift pump
Control enters the inflow in reactor cabinet；The property of can choose opens lighting apparatus at night or cloudy day, numerous to increase microalgae
Grow required light source.
