Problems solved by technology

However, there are following problems in this way: the seedlings are poured into the wild natural seawater suddenly without any buffering process in the sealing belt filled with oxygen and sufficient seawater, and the seedlings fall into the water at a high speed. In addition, the temperature, salinity and pH of the natural seawater in the wild and the seawater in the sealed bag vary greatly, which can easily cause severe stress responses of seedlings and increase sudden mortality

Embodiment 1

[0027] like Figure 1-3 Shown in , 7, the buffer device for the multiplication and discharge of aquatic product seed comprises a casing 1, and the upper side of the casing 1 is obliquely connected with the seedling feeding pipe 4, and the lower side is obliquely connected with the emergence pipe 9, and the seedling emergence pipe 9 below is provided with the casing 1 The guide plate 10 connected to the outer wall, the emergence pipe 9 is connected with a seedling separator 8 and a valve is provided at the connection, the seedling separator 8 includes a cylindrical housing 801, and the inner cavity of the housing 801 is composed of several shells that can be wound around the housing 801. The dividing plate 802 that the axis rotates separates, and in the process of releasing the seedlings, the seedlings are first placed in the casing 1 through the seedling feeding pipe 4 to temporarily raise the seedlings. Place half of the water body in the release area to make the seedlings in...

Embodiment 2

[0032] The further optimization scheme of this embodiment on the basis of embodiment 1 is, as Figure 4 , 5 , 6, the surface of the buffer plate 6 is provided with a swingable flow divider 5, the flow divider 5 includes a swing plate 501 connected to a rotatable shaft at the end, the side of the swing plate 501 is obliquely provided with an elastic plate 502, and the bottom surface of the elastic plate 502 is connected with a The slide bar 503 that can slide on the surface of the swing plate 501, when the seedlings are released from the seedling inlet pipe 4 outlets to the surface of the buffer plate 6, the swingable flow divider 5 can disperse the too concentrated seedlings to avoid the seedlings Too crowded, the elastic board 502 that is provided with can play certain elastic effect to seedling and prevent seedling from being extruded on swinging plate 501 both sides or swinging plate 501 both sides face the frictional damage of seedling.

[0033] The surface of the elastic...

Embodiment 3

[0036] When the buffering device for multiplying and releasing aquatic product seeds of the present invention is actually used: transport the seed and seawater sealed bag packed from Yang to the designated releasing sea area with vehicles and ships, untie the sealed bag after counting, and connect the water inlet pipe 101 with the outside in advance. The pump is connected to the pump, and the water body in the seed discharge water area is drawn into the box body 1, and half of the water body in the discharge area is placed in the box body 1, and the seedlings are put into the box body 1 by the seedling feeding pipe 4 for temporary cultivation, so that the seedlings Preliminary adaptation to the release area. During the temporary cultivation of the seedlings, oxygen can be selectively introduced into the box 1 according to the actual situation to ensure the survival rate of the seedlings in the box 1. During the temporary cultivation, the motor 201 The drive shaft 201a drives th...

Abstract

The invention provides a buffering device for proliferation releasing of aquatic fingerlings. The buffering device comprises a box body, a fingerling inlet pipe is obliquely connected to the upper portion of the side of the box body, a fingerling outlet pipe is connected obliquely to the lower portion of the side of the box body, a guiding plate connected with the outer wall of the box body is arranged below the fingerling outlet pipe, a fingerling separating device is connected to the fingerling outlet pipe through penetration, a valve is arranged at the connecting position, the fingerling separating device comprises a cylindrical shell, and an inner cavity of the shell is divided by multiple dividing plates capable of rotating around the axis of the shell. With the device, the effect ofadaptation of the released fingerlings to the oxygen content in water can be improved, foams gathering on the water surface can be eliminated, the fingerlings are released in batches, a stress reaction of the fingerlings to the environment is relieved, and the death rate of the fingerlings is decreased.

Description

technical field [0001] The invention belongs to the technical field of seed releasing, and in particular relates to a buffer device for multiplying and releasing aquatic seed. Background technique [0002] According to FAO statistics, from 1984 to 1997, a total of 80 countries attempted to increase and release 184 species. Unfortunately, most marine biological resources have not achieved the expected results. Many scholars have analyzed the deficiencies and defects in the breeding and releasing process from multiple angles, and put forward improvement measures. Our country has been carrying out multiplication and release since 1984, and now it has developed to a scale of more than a dozen species and tens of billions of tails (heads and grains) every year. The current multiplication and release of aquatic seedlings is usually packed with oxygenated seedlings and seawater sealed bags, transported by vehicles and ships to the designated release sea area and counted, then the ...
