Description
Technical Field
The application belongs to the technical field of fish egg hatching, and particularly relates to a hatching and seedling raising device for micro-water-flow marine buoyancy fish eggs.
Background
The aquatic product cultivation yield of China is more than 70% of the total aquatic product amount of China. The supply of fish fries is an important basis for the healthy and sustainable development of the aquaculture industry. At present, most of large-scale freshwater fishes can finish artificial breeding in a large-scale and commercial mode, and offspring seeds of the large-scale freshwater fishes can be stably and continuously supplied to the market. Most of the current designs of the aquatic hatching equipment are only suitable for hatching freshwater fish.
Along with the improvement of the living standard of people, the traditional fresh water aquatic products can not meet the demands of people on the aquatic products, and compared with most fresh water aquatic products, the sea water aquatic products have the advantages of less peculiar smell, rich nutrition and delicious taste, and are gradually favored by consumers; meanwhile, the development of the seawater aquarium industry increases the population pressure of wild seawater fish, and research on hot species artificial breeding technology is urgently needed. However, most of the sea water edible fishes and sea water ornamental fishes still need to be caught in the wild, taking the sea water ornamental fishes as an example, at present, only more than 30 sea water ornamental fishes which are artificially bred at home and abroad are realized, but the sea water ornamental fishes which participate in aquarium trade are as many as hundreds of sea water ornamental fishes, and the sea water ornamental fishes cannot be subjected to a large technical bottleneck of artificial breeding on a wide variety, namely lack of proper hatching and seedling raising equipment for carrying out the development of artificial breeding work. Compared with fresh water fish fries, the marine fish fries are weaker, weaker water flow, more oxygen-enriched water body and more stable environment are needed, so that a device for hatching and raising seedlings of micro-water marine planktonic fish eggs is needed, the single fish egg hatching amount and hatching rate are improved, the fish fry damage in the hatching and transferring process is reduced, the survival rate of the fish fries in the raising process is improved, and the device is used for solving the problems of high-value marine economy and artificial breeding of ornamental fish at present.
Most of hatching devices in the market at present are devices for hatching freshwater fish eggs, but most of freshwater fish eggs have large egg diameters and tough egg membranes, and the initially hatched fries are large, can independently swim and actively ingest exogenous nutrient substances, have good stress resistance and are insensitive to mechanical damage caused by external environment change and water flow. However, many sea water fish eggs, small parts of fresh water fish eggs and eel eggs are small in egg diameter and sensitive to external environment change, and the initial hatched fries are poor in stress resistance and poor in autonomous swimming ability, so that certain water flow environments are needed to assist in predation, and the fries cannot be damaged by excessively excited water flow. Meanwhile, most hatching equipment cannot bear subsequent seedling raising work, so that a great deal of loss is caused in the process of transferring some varieties after hatching, the success rate and the economic income of seedling raising workers are directly influenced, for example, chinese patent 201820754685.2, 12 months and 14 days of publication date 2018, discloses a device and a device for hatching heavy spawn fish fries, which comprise a hatching barrel, a water draining barrel, a porous plate, an aeration plate and a blower; the device utilizes the comprehensive effect of water flow and air flow to avoid the mutual adhesion of fish eggs and increase the oxygen solubility in water, thereby improving the hatching rate of the fish eggs; however, the device and the equipment use air flow for hatching, and the water flow speed cannot be accurately regulated, so that artificial hatching of fish eggs with smaller diameters is difficult to complete, and the water flow driven by air bubbles can also cause mechanical damage to the weak initially hatched fish. In view of the above, according to the shortcomings of the existing hatching device, there is a need for a fry hatching device with water flow driving, controllable flow rate, controllable water quality, integrated hatching and raising, and reduced mechanical damage of fries in a container, but no report has been made on such devices.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1 to 4, the embodiment of the application provides a hatching and raising device for micro-water-flow marine buoyancy fish eggs, which comprises a water storage box 1 and also comprises,
an incubation cylinder 2 which is arranged in the water storage box 1 and forms four diagonal cavities with the inner cavity of the water storage box 1,

wherein, water is injected into the diagonal cavity through the first ball valve 4 and the second ball valve 5, water is injected into the incubation cylinder 2 through the water tank 3, and water flow is guided by the water guide plate 7 to form circulation;
as shown in fig. 1-4, the device can hatch eggs of eel, sparrow, nojirimi, soyate and the like, place the eggs to be hatched into the incubation barrel 2, adjust the flow rate of water inflow through the first ball valve 4 and the second ball valve 5, process the water inflow through the water tank 3 and introduce the water inflow into the incubation barrel 2, and conduct auxiliary drainage through the water guide plate 7, thereby forming annular water flow inside, causing the eggs not to be easily adsorbed on the drainage barrel 6, but to flow along with the annular water flow. After the fish eggs are hatched into the fries, the water inlet speed of the ball valve and the bait organisms required by the fries are increased according to the actual demands of specific fries, and the fries are assisted to swim in water so as to capture food.
Wherein, the incubation cylinder 2 is made of transparent materials, so that workers can directly observe the conditions of spawn development, fish fry predation, bait density, water flow and the like in the incubation container, and make corresponding adjustment in time. The material is selected from acrylic.
The arc of the cut-out portion of the top of the incubation barrel 2 is 45 ° so that the operator can operate the inside of the incubation container from above.
The length of the incubation cylinder 2 is 80cm, the height is 51.1cm, and the side diameter is 60cm;
the water storage box 1 is made of transparent acrylic material, and the water inlet pipeline is a PVC pipe with DN25 mm.
Wherein, the first ball valve 4 and the second ball valve 5 are respectively communicated with the diagonal cavities at the upper left and the lower right in the water storage box 1, and the four diagonal cavities are mutually independent;
the independent diagonal cavities are filled with water without stopping water injection, and water pressure in the diagonal cavities is poured into the incubation barrel 2 through water pressure in the diagonal cavities, so that water flow can be obtained, and the upper diagonal cavities and the lower diagonal cavities are matched to form an annular water flow state.
The top of the inner cavity of the incubation barrel 2 is also provided with a ball screw 8, the ball screw 8 is in driving connection with a sliding block 81, the sliding block 81 is connected with a support frame 9, the upper side and the lower side of the inner wall of the support frame 9 are provided with switches 10 for driving motors 12 arranged outside the water storage box 1, and the middle part of the support frame 9 is also provided with a floating body structure 11;
as shown in fig. 1 and 2, the supporting frame 9 is sleeved on a guide rod, can move up and down freely and cannot be washed away by water flow, the supporting frame 9 can reach a set height through adjustment of the ball screw 8, when the water level rises, the floating body structure 11 is upwards touched by buoyancy to the switch 10 positioned at the top of the supporting frame 9, then the switch 10 controls the motor to positively rotate to adjust and reduce the water flow of the water drainage cylinder 6 so as to enable the liquid level to fall, when the liquid level lowers the floating body structure 11, the switch 10 positioned below the supporting frame 9 can be touched, the motor is reversely rotated to adjust and reduce the water flow of the water drainage cylinder 6 so as to enable the liquid level to rise, and therefore the liquid level can be always kept in a dynamic balance state.
Wherein the motor 12 adjusts the water passage area of the surface of the drain cylinder 6.
The drainage tube 6 comprises nylon cloth 61, a structural framework 62 for supporting the nylon cloth 61 and a water-blocking bone piece 63 attached to the inner side of the structural framework 62, and the motor 12 is in transmission connection with the water-blocking bone piece 63;
as shown in fig. 4, the construction frameworks 62 are distributed in an equidistant annular array, and there are spare cracks between two adjacent construction frameworks 62, through which water can permeate into the drainage tube 6, while the water-blocking bone pieces 63 on the inner side can adjust the overlapping area with the cracks through rotation, so that when the motor drives the water-blocking bone pieces 63 to rotate, the water permeation speed can be directly interfered. The rotation increases the overlapping area of the water-blocking sheet 63 with the nip, and the penetration speed becomes slow, and the decrease of the overlapping area with the nip, and the penetration speed becomes fast. At the same time, the shielded part can lose negative pressure through the adjustment of the area of the crack, so that a small amount of fish eggs originally adsorbed on the shielded part can fall off due to the double functions of the disappearance of the negative pressure and water flow.
Wherein, the included angle of the tangential plane at the joint of the water guide plate 7 and the incubation cylinder 2 is adjustable;
the included angle is mainly determined according to the water level in the incubation barrel 2, when the water level is relatively high, water with a higher water level needs to flow, and then the included angle with the tangential plane can be properly reduced. When the water level is lower, the included angle can be properly increased, and the phenomenon that the water flow directly causes uneven liquid level and water flow disorder is avoided.
Wherein the water guide plate 7 comprises an arc-shaped plate and a straight plate;
the arc-shaped plate and the straight plate are both adaptive and can be selected according to different diversion requirements, and the plates in the two forms are easy to process and low in cost.
Working principle and using flow:
according to the application, the annular water flow is formed in the incubation barrel 2 to drive the fish eggs to flow along with the water flow, the continuous floating state of the fish eggs in the nature is simulated, the water flow is used for assisting the fish larvae to predate, meanwhile, the water in the fish eggs is also permeated outwards through the water drainage barrel 6, so that water circulation can be formed, the operations such as oxygen supply and water purification can be realized, the fish eggs in the fish eggs can be filtered out through the water drainage barrel 6, the fish eggs are prevented from being discharged out of the device, the negative pressure on the surface of the fish eggs is changed through the adjustable water drainage barrel 6, the adsorbed fish eggs can fall off from the fish eggs by means of the water flow, and the low survival rate caused by adsorption of the fish eggs is prevented.
