The invention relates to a device for collecting plankton, which includes a screen block and a collection box. The collection box is a box-shaped object made of a screen with four side walls, a closed bottom surface and an open top. There is an opening, and the outer side of the opening is connected with two blocks made of screen mesh at an angle to each other. Both the block and the storage box are provided with supports to ensure that the two can float on the water surface and be fixed in place. The present invention uses the water flow generator to push the plankton in the water body into the two block nets, and sends the plankton into the collection box under the joint action of the water flow and the block nets, and the plankton are further densely collected in the collection net box and collected. Personnel use small fishing nets to fish out the living plankton in the collection box, and pack and transport them for feeding economic aquatic seedlings, so as to realize the attraction, push, intensive and harvesting of plankton in natural waters or artificial culture ponds in large water bodies the goal of.
Description
Technical field
The present invention relates to a kind of device for catching plankton.
Background technology
At present, the living body bait principal item in early stage of economic aquatic product sprout productions such as fish, shrimp, crab is microalgae, wheel animalcule, artemia nauplii etc. both at home and abroad.Because it is the microalgae individuality is less, general only as the open-mouthed bait of economic seed or the bait of this seed living body bait (wheel animalcule, artemia nauplii etc.); Though the individuality of wheel animalcule is more much bigger than microalgae, along with the growth of seed, its nutritive value seems and very is short of that for most economic aquatic product sprout, should not surpass for 2 weeks the longest service time; Though the artemia nauplii individuality is big slightly, because its expensive high price, limited nutritive value and loaded down with trivial details artificial incubation work, desirable bait that neither the economic aquatic product sprout intermediary and later stages.Put into practice verified: at the middle and later periods cultivation stage of most fish shrimp crab class seed, the not only individual suitable size of copepoda, and also nutrient component is abundant, is its best bait.Though also there is the operating type that has adopted set net to fish for the sea area copepoda in domestic indivedual at present area; but set net will lean on action of ocean current to collect plankton; and ocean current is changeable, the time little when big, this catches output, receives the keep-alive of catching object etc. and bring significant limitation and lability to receipts.Problems such as that economic aquatic product sprout living animal feed source lability, underproduce, food nutrition are worth is not good enough, production cost height have become the at present domestic and international economic aquatic product sprout of restriction and have produced fast-developing principal element.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of and be applicable to hydrostatic or the receipts device for catching of the plankton keep-alive amount that the increased receipts in the waters of flowing slowly are caught.
For achieving the above object, the present invention adopts a kind of device for catching plankton, device for catching plankton comprises block and matter collecting box, matter collecting box is the case shape thing of being made by screen cloth with the sealing of four sidewalls and bottom surface, top end opening, offer opening on its perisporium one side, open outer side is connected with two each other and be the block of being made by screen cloth of angle, and both can swim on the water surface all to be provided with assurance on block and the matter collecting box, and are fixed on the supporter in original place.
In order to help planktonic luring in night, and be convenient to the operation in evening, device for catching plankton of the present invention also comprises the plankton lure lamp, and the plankton lure lamp is arranged in the angular range that two blocks form.
In order to enlarge the application scenario of device for catching plankton, device for catching plankton of the present invention also comprises the current generator that promotes water (flow) direction, and the current generator is arranged on angular range that two blocks form foremost.
In order to block and the enhancing resistance to tension and service life of matter collecting box, the present invention's canvas that on the periphery of block and matter collecting box, all has been sticked.
The invention provides a kind of device for catching plankton, utilize the current generator that the plankton in the water body is pushed in two blocks, under the acting in conjunction of current and block, plankton is sent into matter collecting box, plankton quilt in collection thing net cage is further intensive, the receipts person of capturing a prisoner is regularly pulled live body plankton in the matter collecting box out with little dredger, through packed and transported for the use of throwing something and feeding of economic aquatic product sprout, realize with the plankton in the natural water area or the big water body artificial culture pool lure, propelling movement, intensive, receive the purpose of catching.The present invention has following advantage: planktons such as the live body copepoda that receipts are caught, cladocera are injured less, keep-alive is easy, and nutritive value head and shoulders above traditional biological bait artemia nauplii at present commonly used, but cost is than buying low many of artemia ovum hatching nauplius; The present invention is highly suitable for not having originally current or the current water surface very slowly, especially cultures the pool, cistern, clarifier-tank etc. and locates, and the water surface more anxious at current also can be suitable for, and can reduce but receive the plankton keep-alive amount of catching.In the retaining pool of nursery, use, also help the biomass that reduces non-direct production in the water body, all have certain effect purifying water, improve weed survival rate; Natural plankton resource natural propagation in present China cultivating pool, unemployed, easy regeneration that the present invention can make full use of is for a new approach that applicability is wide, potentiality to be exploited is big is excavated in the high-quality living body bait production of China's aquatic product sprout; Simple, easy to use, harvest rate height is drawn materials easily, made to apparatus of the present invention, and in the waters, only use material and technology such as light, current generator and block, neither need extraneous inwardly reinforcedly, also can not arrange thing, have good characteristics such as economic, practical, efficient, environmental protection to the external world.
