Aquaculture pond bottom cleaning method

Abstract

The invention relates to a method for aquaculture, in particular to an aquaculture pond bottom cleaning method. The method comprises the following steps of first cleaning, wherein a water filling pipe is filled with water, a pond bottom water body is isolated from an upper water body, and water and garbage below the water filling pipe are pumped out through a water pump pipe; second cleaning, wherein water is supplied to the water filing pipe in a pulse water supply mode, garbage falling onto the water filling pipe and an air filling pipe is made to fall to the pond bottom, the water filling pipe is filled water again, the pond bottom water body is isolated from the upper water body, and then water and garbage below the water filling pipe are pumped out through the water pump pipe; third cleaning, wherein the water filling pipe is filled with water, the pond bottom water body is isolated from the upper water body, and the water pump pipe supplies water reversely at the same time, so that the garbage in a gap of the water filling pipe is rushed out, then, water and garbage below the water filling pipe are pumped out through the water pump pipe, and pond bottom cleaning is completed. According to the cleaning method, the water resource is saved, the influence on fishes and shrimps is small, and the pond bottom garbage can be collected thoroughly.

Description

technical field [0001] The invention relates to a method for aquaculture, in particular to a method for cleaning the bottom of an aquaculture pond. Background technique [0002] With the continuous development of aquaculture technology, fish, shrimp, etc. can be efficiently cultured in factory farming workshops. Aquaculture ponds are set in the cultivation workshops. Most of the aquaculture ponds are square or round. Sprinkle feed in the pond to provide food for fish and shrimp. Due to the high density of fish and shrimp in the breeding pond, and the feeding situation of each fish and shrimp changes with the body changes, loss of appetite often occurs. At this time, it is easy to produce For the rest of the feed, the feed sinks to the bottom of the water and accumulates continuously.

[0002] With the continuous development of aquaculture technology, fish, shrimp, etc. can be efficiently cultured in factory farming workshops. Aquaculture ponds are set in the cultivation workshops. Most of the aquaculture ponds are square or round. Sprinkle feed in the pond to provide food for fish and shrimp. Due to the high density of fish and shrimp in the breeding pond, and the feeding situation of each fish and shrimp changes with the body changes, loss of appetite often occurs. At this time, it is easy to produce For the rest of the feed, the feed sinks to the bottom of the water and accumulates continuously. Soaking in water for a long time will not only make the water turbid, but also easily breed bacteria and viruses, causing changes in water quality and deteriorating the breeding environment, especially in summer when the temperature is high. Shrimp is sick and dies in large numbers, so it is necessary to clean up the garbage at the bottom of the pond frequently

[0003] There are usually two existing cleaning methods: one is to pump out the pool water and then clean the bottom of the pool. This method not only consumes a lot of water resources, but also is not easy to operate, because usually another container or pool is needed to transfer fish and shrimp Another method is to make the bottom of the aquaculture pond into a concave spherical shape, and then vigorously stir the water in the pool to rotate, thus forming a vortex, which drives the garbage to gather at the bottom of the pool center, and then pumps out the water in the center continuously , and then carry garbage. Although this method saves water resources to a certain extent, there are still two problems. The cost is large, and the second is to stir the water flow in the whole pond, which will affect the normal rest of the fish and shrimp, and even make them frightened, and the frightened fish and shrimp for a long time are also prone to illness and death
