Quick-acting environment-friendly pool cleaning method for procambarus clarkii

Abstract

The invention relates to a quick-acting environment-friendly pool cleaning method for procambarus clarkia. The quick-acting environment-friendly pool cleaning method comprises the following steps that derris roots are cut into thin slices and are crushed into fine powder after being dried, the sieving is carried out by a bolting silk screen, and derris root powder is prepared; during the procambarus clarkia pool cleaning, about 1-1.5kg of derris root powder is used for 667m<3> of water bodies and is added into a pool to be soaked by clean water, then, the water and the slag are simultaneously and uniformly spread into the pool, and wild trash fishes can be fast killed in 2-4 hours; and after the pool cleaning and sterilization through the derris root powder, fermented organic manure of pigeon manure or rabbit manure can be spread into the water bodies, and shrimp seeds can be placed into the pool after 5-7 days after the fermentation. The natural Chinese herbal medicine plant of the derris is adopted to be prepared into the pool cleaning medicine, the process is simple, the operation is convenient, and compared with the conventional pool cleaning medicine, the prepared derris root powder has the advantages that the effect taking speed is high, the efficiency is high, the medicine dosage is low, the production cost is low, green and environment-friendly effects are realized, the degradation in the water bodies is easy, no medicine residue is left, the derris root powder is safe on pool remaining propagating parent procambarus clarkia, shrimp seeds and waterweeds, and the like. The method provided by the invention is particularly suitable for being used for pool cleaning during the procambarus clarkia culture.

Description

technical field [0001] The invention relates to a pond clearing method, in particular to a quick-acting and environment-friendly pond clearing method for Procambarus clarkii culture ponds, and belongs to the technical field of aquaculture. Background technique [0002] Cleaning pond is the first step in aquaculture, and it is the basic work in the early stage of Procambarus clarkii aquaculture production. Clearing pond can effectively remove wild fish, aquatic insects, filamentous algae, parasites and pathogenic bacteria in shrimp ponds All kinds of harmful organisms, such as shrimp, play a key role in improving the survival rate of seedlings and healthy breeding of adult shrimp. Harmful organisms in shrimp ponds, such as ferocious fish, can prey on shrimp juveniles and molting juveniles in large quantities, affecting the growth and survival of shrimp; animals that compete with shrimp, such as wild fish, occupy the water body space with shrimp, and grab food Feed causes was...

Problems solved by technology

Since quicklime and bleaching powder belong to the "all-killing" pond cleaning drugs, while completely killing the enemy organisms, they also have strong lethality to the broodstock of Procambarus clarkii and the bred shrimp seedlings bred in the pond, causing Ovipositing broodstock and filmed shrimp were killed, resulting in a decrease in the number of Procambarus clarkii seedlings, which is not conducive to the reproduction and production of Procambarus clarkii seedlings; in addition, Procambarus clarkii is omnivorous shrimp, and aquatic plants, Snails are an important natural bait for shrimps. At the same time, aquatic plants are also needed to provide shelter when shrimp molt.

However, the "all-killing" clearing pond medicine will kill the aquatic plants, snails and other animal and plant bait in the shrimp pond, which is not suitable for the clearing pond of Procambarus clarkii breeding ponds.
