Embodiment 1

[0037] A kind of round-mouthed copper fry simple and easy circulation aquaculture method, it comprises the following steps:

[0038] 1. Breeding supporting facilities: the water inlet pool is a 396cm×84cm circular plastic pool, and bricks are pressed on the bottom of the pool to prevent the pool from being scratched by excessive river water activities. An ozone generator (10g / h, 130 watts) is equipped in the pool ); the water entering the sedimentation tank is pumped up by the water pump and then filtered through the gauze filter bag before entering the sedimentation tank. After sedimentation in the sedimentation tank for 5-7 days, the ozone is treated for 3-6 hours, and then enters the storage tank through the water pump. The storage tank adopts A circular plastic pond with the same specifications as the sedimentation tank; a single breeding pond is a square plastic pond with a length of 2.39 meters, a width of 1.5 meters and a height of 0.58 meters, with a drainage port on th...

Embodiment 2

[0046] The utility model relates to a simple circular aquaculture device for round mouth copper fish fry, which is composed of an ozone generator, two pools, two culture pools, four water pumps, four aerators, two ultraviolet sterilizers and the like. The specific connection layout and functions are as follows: the ozone generator 1 is directly connected to the sedimentation tank 3 through the air pipe 2, and sterilizes the water in the pool; the water pump 4 is connected to the sedimentation tank 3 through the water pipe 5 and the filter bag 6, and the river water is filtered through the filter bag 6 The water pump 7 is connected with the reservoir 9 through the water pipe 8 and the filter bag 15, so as to replenish the fresh water to the circulation system; the aeration pump 10 is connected with the reservoir 9 through the air pipe 11, and the water body is charged Oxygen aeration: the aeration pump 12 is connected to the reservoir 9 through the trachea 13 and the sponge filt...

Abstract

The invention discloses a simple circulating water culture method and device of coreius guichenoti fries. The method comprises the following steps: A, constructing culture supporting facilities of coreius guichenoti fries, wherein the culture supporting facilities include an exogenous water treatment facility, culture equipment and a circulating water treatment system; B, adjusting and controllingthe water quality of water in a culture pool to obtain soft water of which the pH value is weakly alkaline; C, putting the coreius guichenoti fries into the pool, and then, feeding palatable bait according to different ages of the moon and mouth sizes of fishes; and D, preventing and treating fish diseases in a high-density culture process of the coreius guichenoti fries, namely spraying sea saltfor aquatic products, povidone-iodine, an enrofloxacin injection or hanging bag type chlorine dioxide effervescent tablets and isatis root powder in the whole pool so as to perform medication. The device is composed of an ozone generator, a pond, a culture pool, a water pump, an aerator, an ultraviolet sterilizer and a water pipe device. The method is easy to realize and simple and convenient tooperate, realizes intensive and efficient culture, fully utilizes limited purified water, and realizes a higher culture survival rate.

Description

technical field [0001] The invention belongs to the field of fish fingerling breeding, and more specifically relates to a simple circulating aquaculture method for round-mouthed copper fish fry, and also relates to a simple circulating aquaculture device for round-mouthed copper fish fry, which is suitable for large climate changes, poor water quality, Fish breeding in places where water is scarce. Background technique [0002] The round-mouthed copperfish (Coreius guichenoti) belongs to the Cypriniformes (Cypriniformes), Cyprinidae (Cyprinidae), Gobioninae (Gobioninae) copperfish genus (Coreius). In recent years, the disturbance of human activities such as water conservancy project construction and overfishing have had a great impact on the survival and reproduction of copperfish, and the issue of species protection has attracted increasing attention. Recirculating aquaculture This fish species is still in the exploratory stage, and a set of reliable high survival rate rec...
