Embodiment 1

[0017] Embodiment 1: As shown in the figure, a circulating water three-dimensional culture system of Portunus trituberculatus, including a reservoir 1, a water pump (not shown in the figure) and four layers of culture box groups with upper openings, adjacent two layers of culture boxes The front and back of the box group are staggered, and the bottom front side of the culture box group at the bottom is provided with a sump 2, and the filter biochemical cotton is laid in the sump 2 (not shown in the figure), and the sump 2 and the reservoir 1 are connected with Outlet pipe 3, the top of the breeding box group on the top floor is fixedly provided with water spray pipe 4, is communicated with by water inlet pipe 5 between water spray pipe 4 and reservoir 1, and water spray pipe 4 is provided with a plurality of water spray holes ( Not shown in the figure), the breeding box group is made up of a plurality of breeding boxes, and the breeding box includes a box body 6 with an open up...

Embodiment 2

[0019] Embodiment two: as shown in the figure, other structures are the same as embodiment one, and the difference is that the top of each layer of breeding box group in the second layer of breeding box group to the bottom layer of breeding box group is also fixedly provided with independent water spray pipes respectively 4. The water spray pipe 4 communicates with the reservoir 1 through an independent water inlet pipe 5 . The water spray pipe 4 is provided with a plurality of water spray holes (not shown in the figure), and the water inlet pipe 5 is provided with a valve 51 .

[0020] In above-mentioned two embodiments, according to the size of the maximum individual range of activities of Portunus trituberculatus, the following sizes can be selected in the following ranges: the range of the adjacent two-layer breeding box group is 40-60mm, and the two adjacent The interval range of the water spray holes is 5-15mm, the aperture size range of the water spray holes is 1-3mm, th...

Abstract

The invention discloses a circulating water three-dimensional cultivating system for blue crabs, which is characterized by comprising a reservoir, a water pump and at least two layers of cultivating box groups with openings at upper ends, wherein the adjacent two layers of the cultivating box groups are staggered in the front and back direction, a water collecting tank is arranged on the front side at the lower end of the cultivating box group positioned in the bottom layer, filter biochemical cotton is laid in the water collecting tank, a water outlet pipe is connected between the water collecting tank and the reservoir, a water spray pipe is fixedly arranged above the cultivating box group in the top layer, the water spray pipe is communicated with the reservoir through a water inlet pipe, and a plurality of water spray holes are arranged on the water spray pipe. The circulating water three-dimensional cultivating system has the advantages that water used by the system can be recycled after being filtered, the water consumption is low, and the system can realize energy conservation and emission reduction and is conductive to environmental protection; and furthermore, oxygenation is performed between the upper and the lower layers of the cultivating box groups through the gravity action of water flow, and one blue crab is cultivated in one cultivating box, so that the survival rate of cultivation is high and the management is simultaneously facilitated.

Description

technical field [0001] The invention relates to a culture device, in particular to a circulating water three-dimensional culture system for Portunus trituberculatus. Background technique [0002] Portunus trituberculatus is an important marine cultured crab in my country, widely distributed in the coastal areas of China. At present, the culture of portunus trituberculatus mainly adopts traditional earthen pond culture. With this culture method, the breeding environment is greatly affected by the weather, water quality is difficult to control, and there are many diseases. At the same time, due to the habit of killing each other, portunus trituberculatus individuals , leading to a very low survival rate. Moreover, the traditional earthen pond aquaculture occupies a large area and consumes a large amount of water. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional culture system of Portunus tritu...
