Description
Technical Field
The utility model belongs to the technical field of aquaculture, and particularly relates to a pool pouring device for young puffer fish.
Background
The common names of the puffer green (Thamnaconus septentrionalis) are peeled fish, consumed fish, pig fish and carpenter fish, are mainly distributed in the northwest of the pacific, are the migratory outer sea near-bottom fishes of the ocean, and are important economic fishes in coastal areas of China. The edible part of the puffer green has no hard thorns, the meat is delicious and chewy, the nutritive value is high, and the puffer green is popular with the masses. The fish meat can be eaten fresh or processed into dried fish, or concentrated fish protein, fish meal, peptone, biochemical culture medium, cod liver oil, lipid-lowering pill, etc. can be prepared, and has high economic value.
In the artificial breeding process of the puffer green, the water quality is deteriorated due to accumulation of excrement and residual baits at the bottom of a breeding pool, and the young fish is often required to be poured into the pool. The current common method of inverting the pool is to use a bailer or siphon. The use of the fishing net has the defect that the fish body is easy to damage, and the first dorsal fin of the puffer fish is a hard spine which can be erected and is often hung on the net clothing of the fishing net, so that the whole individual is also hung on the net clothing and cannot be separated smoothly, and the fish body is often required to be separated manually, so that the fish body is damaged. The siphon method has the defect that the feces and residual baits which are bred with bacteria are easily sucked into a new pool. Therefore, the development of a pool pouring method for reducing the damage of fish bodies and the residual of excrement and residual baits is very important for optimizing the cultivation technology of the fries of the puffer green.
Disclosure of Invention
The utility model provides a pool pouring device and method for young fish of puffer green, which are used for inducing young fish clusters through baits and collecting young fish by using a fine screen, so that pool pouring efficiency can be effectively improved and damage to the young fish in the pool pouring process can be reduced.
The utility model is completed according to the following operation technology:
a pool pouring device for young puffer fish, which comprises a collecting basket, a bait bag and a power lifting device; the collecting basket is a fine screen, is hollow hemispherical, is connected with ropes at the upper edge of the collecting basket and is used for lifting the collecting basket, bait bags are hung in the collecting basket, and the power lifting device is used for lifting the collecting basket.
Further, the collecting basket is made of stainless steel materials.
Further, the collecting basket is made of hard PVC material.
The using method of the device comprises the following steps: placing the bait into the bait bag, and tensioning the telescopic mouth of the bait bag. The collecting basket and the bait bag are put into the seedling raising pool through the power lifting device, so that the bait bag is completely immersed in water. When the juvenile fishes are attracted by the baits and are ingested in a cluster, the power lifting device is utilized to slowly lift the collecting basket so as to avoid surprise of fish shoals, the upper edge of the collecting basket is taken down from the lifting device after the upper edge of the collecting basket is exposed out of the water surface, and the juvenile fishes obtained through collection are transferred into a new pool.
Compared with the prior art, the utility model has the beneficial effects that: 1. the damage to the fish body is small: when the fishing net is used for pouring juvenile fish into the pool, the first dorsal fin of the green fin puffer fish is a cocked hard spine, and is often hung on a net, so that the damage to the fish body is easily caused. The collecting basket provided by the utility model is a fine screen, so that the hard spines are prevented from being hung and the damage to the fish body is reduced.
2. The feces and the residual bait are less carried: when the siphon method is used for pouring the pool, the excrement and the residual bait in the original pool are easily sucked into a new pool, so that bacteria are bred. The collecting basket screen provided by the utility model can filter most of excrement and residual baits, and is beneficial to disease prevention and control after young fish are poured into a new pool.
Drawings
Fig. 1 is a schematic structural diagram of the device of the present utility model: 1. the collecting basket, 2, rope, 3, power lifting device.
Detailed Description
The technical scheme of the present utility model is further explained by examples below, but the scope of the present utility model is not limited in any way by the examples.
Example 1: the pool pouring device for the young puffer fish comprises a collecting basket 1, a bait bag and a power lifting device 3 as shown in figure 1; the collecting basket 1 is a fine steel wire screen mesh, can also be made of hard PVC material and is hollow hemispherical, the upper edge of the collecting basket 1 is connected with a nylon rope 2 for lifting the collecting basket 1, a bait bag is hung in the collecting basket 1, and the power lifting device 3 is used for lifting the collecting basket 1.
The height of the collecting basket 1 is 30cm, and the diameter of the basket opening of the collecting basket 1 is 60cm; the upper edge of the collecting basket 1 is connected with 3 nylon ropes for lifting the collecting basket 1; the bait bag is a nylon mesh bag, the upper end of the bait bag is provided with a telescopic opening of an annular rope, the lower end of the bait bag is of a closed design, the diameter of the telescopic opening is 3cm, the height of the telescopic opening is 5cm, and the bait bag is connected with the upper edge of the nylon rope 2 lifted by the collecting basket 1 through the nylon rope; the power lifting device 3 is a small crane with the height of 200cm.
Pouring young fish (0.9-1.2 cm) of the puffer fish after hatching for 30 days, putting 5g of minced shrimp bait into a bait bag, and tensioning a telescopic mouth. The collecting basket 1 and the bait bag are put into a seedling raising pool through the power lifting device 3, so that the bait bag is completely immersed in water. After 5 minutes, a large number of fed juvenile fish were gathered around the bait bag. The power lifting device 3 is utilized to slowly lift the collecting basket 1, the state of the fish school is observed, the fish school is prevented from being disturbed, and after the upper edge of the basket 1 to be collected is exposed out of the water surface, the juvenile fish gathered in the fish school are all collected into the basket. And (3) carrying out a pool inversion collection test on 3 seedling raising pools, wherein each seedling raising pool is used for collecting 3 thousands of juvenile fishes, counting the number of juvenile fishes collected each time, randomly picking out 100 juvenile fishes respectively, transferring the juvenile fishes into an experimental barrel, and counting the survival rate of the juvenile fishes after 3 days of pool inversion. The result shows that the number interval of the juvenile fish collected for a single time is 5117 to 7632, and the average number of the juvenile fish is 6761+/-698 each time; after 3 days of pond inversion, the survival rate of the juvenile fish is 98.9+/-1.2%, which shows that the pond inversion operation has little damage to the fish body and no adverse effect on the subsequent juvenile fish cultivation (tables 1 and 2).
