Problems solved by technology

Its control effect is poor and the control efficiency is low. For apple snails with strong fecundity and fast reproduction speed, it is difficult to achieve the purpose of effective control
Chemical agents are also used for prevention and control, but chemical molluscicides are large in dosage, high in cost, poor in effect, highly toxic to water bodies, seriously pollute water quality, and damage water body ecology

Embodiment 1

[0032] The method of the present invention is used to control the landscape water body of a hatching park in Chengdu. The landscape water body is a square pool with a length and width of 80m×50m. The density of apple snails in the pool is relatively high, and the red egg mass produced by apple snails has been attached to the bank wall 1 of the pool for a long time. Therefore, it not only destroys the normal ecology of the water body, but also has a negative impact on the landscape effect of the pool. The hatchery arranges special personnel to catch apple snails all year round, and collects and concentrates the eggs, but the control effect is limited, and the fishing speed is far behind the speed of apple snail reproduction.

[0033] For above-mentioned landscape water body, adopted technical scheme of the present invention to carry out the control of apple snail, specific implementation situation is as follows:

[0034] S1: Install a flushing mechanism 2 in the pool, specific...

Embodiment 2

[0042]Adopt the method of the present invention to control the artificial lake of a certain park in Yibin City. The artificial lake is a dumbbell-shaped pool with two ends open and the middle closed. The distance between the shores of the two ends of the artificial lake is 150m. The artificial lake has a relatively high density of apple snails, and the red eggs produced by the apple snails have been attached to the shore wall 1 for a long time. Therefore, the normal ecology of the artificial lake is greatly damaged, and the appearance of the lakeshore is also affected. The park arranges special personnel to catch apple snails all year round, and collects and concentrates the eggs, but the control effect is limited, and the fishing speed is far behind the breeding speed of apple snails. There have also been attempts to kill apple snails with chemical agents, but chemical agents also have an impact on other aquatic organisms.

[0043] For this artificial lake, adopted the techn...

Embodiment 3

[0052] Adopt the method of the present invention to control the artificial lake of a scenic spot in Leshan City. The artificial lake is a long circular pool with about 120m between the shores at both ends. The artificial lake has a relatively high density of apple snails, and the red eggs produced by the apple snails have been attached to the shore wall 1 for a long time. Therefore, the normal ecology of the artificial lake is greatly damaged, and the appearance of the lakeshore is also affected. The scenic spot arranges special personnel to catch apple snails all year round, collect and concentrate the eggs, but the control effect is limited, and the fishing speed is far behind the speed of apple snail reproduction. It has also been treated by releasing fish that prey on apple snails, but the effect is not obvious.

[0053] For this artificial lake, adopted the technical scheme of the present invention to carry out the management of apple snails, the specific implementation ...

Abstract

The invention discloses a treatment method for apple snails in a landscape water body, and relates to the field of water environment treatment. In view of the fact that the eggs of apple snails cannot develop normally in the water, setting a scour mechanism on the bank wall of the landscape water body makes the apple snails unable to lay eggs normally. By setting a reversible mechanism in the water body, the eggs laid on the apple snails can be conveniently immersed in the water . Utilizing the characteristic that herring mainly feeds on mollusc snails and clams, stock herring in the landscape water body to control the number of apple snails; at the same time, put Procheirus clarkii to prey on apple snails and their eggs on the upper water surface to make up for only putting herring It is difficult to take care of the problem of the upper water surface. On the one hand, block the reproduction of apple snails and control their new numbers; on the other hand, gradually reduce the existing number of apple snails. It not only greatly reduces labor input and does not use chemicals, but also quickly and long-term eliminates the adverse effects of apple snails, and maintains the excellent environment and landscape effects of landscape water bodies.

Description

technical field [0001] The invention relates to the field of water environment treatment, in particular to a treatment method for apple snails in landscape water bodies. Background technique [0002] Apple snails are native to the Amazon River Basin in South America. They were introduced to China in 1981, and were widely bred in Guangdong as a food material after 1984. Due to over-breeding and poor taste, they were released into the wild in large quantities. Since the apple snail is an exotic species, there are few natural enemies in China, and the climatic conditions are very favorable for its growth and reproduction. Every year from April to June and from August to October is the peak period of egg-laying and hatching of apple snails. Apple snails can become adults in 2-3 months, and 200-1000 eggs are laid at a time. After an interval of 3-5 days, the second It can lay eggs once a year, 20-40 times a year, and the amount of eggs laid is 30,000 to 50,000. It takes 10 to ...
