Abstract
The utility model discloses a kind of multilayer freshwater shrimp incubation net cage, it is characterized in that, net cage adopts mesh 0.8 centimeter of polyethylene net sheet to make, net cage is Totally-enclosed-type, and at one angle, place arranges active open from top to down one, is horizontally disposed with some layers of interlayer net sheet in net cage, interlayer net sheet four limits and net cage parietal suture close, 30 centimetres of every layer of interlayer net sheet spacing, on net cage, inferior horn place arranges pulling rope, and pulling rope is fixed on net cage dead lever; Use the utility model net cage, oogenesis freshwater shrimp can be positioned on the interior multilayer interlayer net sheet of net cage, places more oogenesis freshwater shrimp in unit are, improves oogenesis freshwater shrimp quantity in waters, and be independent of each other between oogenesis freshwater shrimp, improved unit of water body freshwater shrimp emergence rate; The utility model net cage is convenient to make, and effect is remarkable, has promotional value.
Description
Technical field
The utility model relates to fish production field, specifically a kind of multilayer freshwater shrimp incubation net cage.
Background technology
Freshwater shrimp belongs to the aquatic animal of oogenesis hatching, oogenesis between the incubation period, generally move in water bottom, because water bottom environment is poor, freshwater shrimp seedling percent is not high, adopts net cage hatching freshwater shrimp survival rate higher, and net cage is generally individual layer, in unit are, oogenesis freshwater shrimp distributed quantity is limited, and freshwater shrimp seedling emergence rate is not high.
Summary of the invention
For overcoming above-mentioned defect, the utility model has designed a kind of multilayer freshwater shrimp incubation net cage.
The technical solution of the utility model is, a kind of multilayer freshwater shrimp incubation net cage, it is characterized in that, net cage adopts mesh 0.8 centimeter of polyethylene net sheet to make, and net cage is Totally-enclosed-type, at one angle, place arranges active open from top to down one, in net cage, be horizontally disposed with some layers of interlayer net sheet, interlayer net sheet four limits and net cage parietal suture close, 30 centimetres of every layer of interlayer net sheet spacing, on net cage, inferior horn place arranges pulling rope, and pulling rope is fixed on net cage dead lever.
Beneficial effect: use the utility model net cage, oogenesis freshwater shrimp can be positioned on the interior multilayer interlayer net sheet of net cage, places more oogenesis freshwater shrimp in unit are, improves oogenesis freshwater shrimp quantity in waters, and be independent of each other between oogenesis freshwater shrimp, improved unit of water body freshwater shrimp emergence rate; The utility model net cage is convenient to make, and effect is remarkable, has promotional value.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
In figure: 1 net cage, 2 pulling ropes, 3 interlayer net sheets, 4 net cage dead levers, 5 net cage walls, 6 active opens.
Embodiment
Accompanying drawings the utility model, a kind of multilayer freshwater shrimp incubation net cage, it is characterized in that, net cage 1 adopts mesh 0.8 centimeter of polyethylene net sheet to make, and net cage 1 is Totally-enclosed-type, at one angle, place arranges active open 6 from top to down one, in net cage 1, be horizontally disposed with some layers of interlayer net sheet 3, interlayer net sheet 3 four limits and net cage wall 5 sewed up, 30 centimetres of every layer of interlayer net sheet 3 spacing, on net cage 1, inferior horn place arranges pulling rope 2, and pulling rope 2 is fixed on net cage dead lever 4; Use the utility model net cage 1, oogenesis freshwater shrimp can be positioned on the interior multilayer interlayer net of net cage 1 sheet 3, places more oogenesis freshwater shrimp in unit are, improves oogenesis freshwater shrimp quantity in waters, and be independent of each other between oogenesis freshwater shrimp, improved unit of water body freshwater shrimp emergence rate; The utility model net cage is convenient to make, and effect is remarkable, has promotional value.
