Embodiment Construction

[0012] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0013] A method for controlling water centipedes in fish ponds, comprising the steps of:

[0014] (1) Disinfect the pond with quicklime water, remove excess silt at the bottom of the fish pond in winter, expose to sunlight for 3-5 days, use 60-80kg / mu of quicklime, and clear the pond when the water depth is 10-20cm, the dosage is 200-250 mg / liter, kill the water centipede and its larvae in the fish pond.

[0015] (2) When the fish pond is filled with water, filter it with linen to prevent the water centipede from entering the fish pond; reduce the probability of the water centipede entering the pond.

Abstract

The invention discloses a method for controlling shortleaf kyllinga herb in a fishpond. The method comprises the following steps: cleaning and sterilizing the pond by using quick lime water, cleaning excessive sludge at the bottom of the fishpond in winter, performing solar exposure for 3-5 days, cleaning the pond by using 60-80kg/mu of quick lime, and killing shortleaf kyllinga herb and larva thereof in the fishpond; filtering and blocking the shortleaf kyllinga herb to enter the fishpond by using linen in the process of injecting water into the fishpond; splashing emulsion diluted by bacteria and insect killers in the fishpond when the shortleaf kyllinga herb exists in the fishpond; and trapping and killing the shortleaf kyllinga herb at night by using lamplight. Compared with the prior art, the method disclosed by the invention has the advantages that the shortleaf kyllinga herb is prevented from entering the fishpond through pond cleaning and sterilization and linen filtration, and the shortleaf kyllinga herb is prevented from entering the fishpond. If the shortleaf kyllinga herb enters the fishpond, the modes of trapping and killing are used by using the emulsion diluted by the bacteria and insect killers and lamplight at night, the existence rate of the shortleaf kyllinga herb mixed in fishes in the fishpond is reduced, the dosage is reduced, the probability of killing fish fries by the shortleaf kyllinga herb is reduced, and sustainable development of fishery industry is promoted.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of fungal diseases of freshwater fish, in particular to a method for preventing and controlling water centipedes in fish ponds. Background technique [0002] Fish ponds are a complex ecosystem. There is sunshine and air above the water surface; there are terrestrial plants on the pond base; there are fish, various aquatic plants, insects, fleas, algae, fungi, bacteria, viruses, and organic and inorganic salts in the water. There is silt at the bottom of the pool, and the above-mentioned organisms, organic matter and inorganic salts also grow. [0003] Water centipedes, also known as water clippers, are the larvae of dragon lice. It is an aquatic insect, both adults and larvae are carnivorous, so it is very harmful to fry. Water centipede, long cylindrical body, with a pair of pincer-shaped mandibles, named after centipede stingers, slightly round head, 6 black monocular eyes on...
