Abstract
The utility model discloses a temporary rearing net cage of Eriocheir sinensis juvenile crabs and relates to a temporary rearing device of the Eriocheir sinensis juvenile crabs. According to the technical scheme, a net cage body and fixing rods are adopted, and the net cage body is a rectangular cage body and is composed of a net cage frame and netting wrapped on the periphery and the bottom face of the net cage frame. The temporary rearing net cage is characterized in that the dimensional specification of the net cage body is 4 meters in the length, 2 meters in the width and 1.5 meters in the height, the screen specification of the netting wrapped on the periphery and the bottom face of the net cage frame is 28-32 screens per square centimeter, four corners of the net cage body are bound and supported through the fixing rods, the fixing rods are erected in the water to enable the upper portion of the net cage body to be higher than the water surface, a transverse isolation net which is arranged in the middle of the length of the net cage body divides the net cage body into a left portion and a right portion, the screen specification of the transverse isolation net is 28-32 screens per square centimeter, the height of the transverse isolation net is three fifths of that of the net cage body, the length of the transverse isolation net is the same as the width of the net cage body, two ends and the bottom side of the transverse isolation net are tied and fixed on the net cage body, and a daylight lamp which is parallel to the transverse isolation net is arranged at the upper end of the right portion of the net cage body.
Description
Technical field
The utility model relates to the temporarily foster device of Eriocheir sinensia juvenile crab.
Background technology
Eriocheir sinensia claims river crab, steamed crab again, and is distributed more widely in China, formed the Eriocheir sinensia 3 big populations based on the Changjiang river, the Oujiang River, the Liaohe River, and wherein the Changjiang river population all is better than other two population at aspects such as proterties and output.The entrance of Changjiang River is the natural spawning ground of the Eriocheir sinensia of China's maximum.In 20 end of the centurys, the Eriocheir sinensia culturist comes entrance of Changjiang River panic buying juvenile crab one after another, and natural juvenile crab was once sold for 80,000 yuan/jin, and the few valency height of amount is called as " soft gold in the water ".The juvenile crab that the spawning ground, entrance of Changjiang River produces has important function because of its good germplasm in the Eriocheir sinensia industry, supporting the high speed development of China's Eriocheir sinensia aquaculture.The time that waters, entrance of Changjiang River juvenile crab plays flood generally at the annual lunar calendar by the end of May, when at the incoming tide, juvenile crab trace back the river and on, this moment the fisherman just utilization diddle-net, net bamboo weir, ship are chosen sampling instrument such as net and are fished for.When the juvenile crab quantity of catching more for a long time, often need juvenile crab is placed in the river course earlier and support temporarily.Therefore, simple and easy to do juvenile crab is supported device temporarily becomes one of active demand of fisherman.
Summary of the invention
The problem that the utility model need solve provides a kind of Eriocheir sinensia juvenile crab simple and easy to do, Cheap highly effective and supports device temporarily.
The technical solution of the utility model adopts net cage and dead lever, and this net cage is rectangular box body, by net cage frame be wrapped in around the net cage frame and the etting of bottom surface constitutes, it is characterized in that the dimensions of net cage is 4 meters, wide 2 meters, high 1.5 meters of length; Be wrapped in around the net cage frame and the mesh specification of the etting of bottom surface is every square centimeter of 28-32 order; Four jiaos of net cage are all adopted the dead lever binding to support, and dead lever is erected in and makes net cage top exceed the water surface in the water; It is two parts about every square centimeter of 28-32 purpose tabula net is divided into net cage that the net cage mid-length has a slice mesh specification, the height of tabula net is 3/5ths of net cage height, the length of tabula net is identical with the width of net cage, and the colligation on net cage of the two ends of tabula net and base is fixed; The upper end of net cage right part is provided with the fluorescent lamp that is parallel to the tabula net.
The utility model has the advantages that simple in structurely, be convenient to the fisherman and buy material voluntarily and assemble use that Cheap highly effective is easy to promote, it is also simple and feasible that whole juvenile crab is supported the operation of flow process temporarily.
Description of drawings
Fig. 1 is the schematic diagram of supporting net cage temporarily of Eriocheir sinensia juvenile crab.
Embodiment
The utility model (referring to accompanying drawing) adopts net cage 3 and dead lever 4, this net cage is rectangular box body, by net cage frame be wrapped in around the net cage frame and the etting of bottom surface constitutes, the dimensions of net cage is selected long 4 meters, wide 2 meters, high 1.5 meters or the rectangular box body that is similar to above-mentioned specification for use; Be wrapped in around the net cage frame and the mesh specification of the etting of bottom surface is every square centimeter of 28-32 order, prevent that juvenile crab from escaping; Four jiaos of net cage are all adopted the dead lever binding to support, and the dead lever height is suited measures to local conditions to be erected in and made net cage top exceed the water surface in case juvenile crab escapes in the water; It is every square centimeter of 28-32 purpose tabula net 2 that the net cage mid-length has a slice mesh specification, two parts about net cage is divided into, the height of tabula net is 3/5ths of net cage height, the length of tabula net is identical with the width of net cage, the two ends of tabula net and base colligation are fixing at net cage, or the edge of tabula net pricked on an iron wire frame earlier, again two ends and the base colligation on net cage of tabula net is fixed, juvenile crab can not be passed through from tabula net and its underpart, but tabula net height degree is limited, and juvenile crab can pass through from the water body of the online side of tabula; The fluorescent lamp 1 that is parallel to the tabula net is housed in the upper end of net cage right part, pour the left part of net cage into when the juvenile crab that catches after, open the fluorescent lamp of net cage right part upper end, the juvenile crab that vigor is good can be under the inducing of light, enter the net cage right part from the net cage left part through filter top water body, the dead juvenile crab with the vigor difference can be stayed net cage left part (pouring that side of juvenile crab into).
