Device and method for culturing of whitman pipa seedlings by microflow water circulation type grid

Abstract

The invention provides a device and a method for culturing of whitman pipa seedlings by a microflow water circulation type grid. The device is characterized in that the grid is arranged in a culture bucket, and a water inlet pipe and a flow spraying pipe are arranged in the culture bucket 1; a water outlet pipe is arranged at the bottom part of the culture bucket; a water overflow pipe is arranged in the culture bucket, and is communicated with the water outlet pipe; the water inlet pipe is communicated with a water storage pool; an electric submersible pump is arranged in the water source, and is communicated with the water storage pool through a pipeline. The method comprises the following steps of 1, preparation in early period; 2, seedling culture of the whitman pipa; 3, feeding and management of the seedlings; 4, management in the culture period; 5, selling standard of the seedlings. The device and the method provided by the invention have the advantages that the culture survival rate of the whitman pipa is increased to more than 60%, the observation and management of the whitman pipa are convenient, and the survival condition is well met.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding, in particular to a device for cultivating wide-bodied leech seedlings in a microflow water circulation grid. Background technique [0002] Wide-body golden leeches (Whitmania pigra Whitman1884), commonly known as leeches, also known as horse leeches, wide-body golden leeches and wide-body leeches, belong to the phylum ANNELIDA, class Hirudinea, and subclass Euhirudinea Lukin. 1956), Arhynchobdellida Blanchard, 1894, Hirudiniformes Caballero, 1952, Haempidae Sawyer, 1986, Whitmania Blanchard, 1888, widely distributed in my country, It is a traditional special medicinal aquatic animal in my country. The whole body of the dried leech is a traditional Chinese medicinal material, which is salty, bitter, flat, and slightly poisonous. Return liver channel. Tool breaks blood to stimulate menstruation, removes blood stasis and eliminates symptoms, and is used for amenorrhea due to blood stasis, abd...

AI Technical Summary

Problems solved by technology

At present, the main breeding method is: directly put the seedlings of the wide-bodied golden line leech into the pond. Although this method reduces the fishing link of the leech species and has the advantage of simple operation, due to insufficient bait and other reasons in production, the leech seedlings cannot be harvested. The growth rate and size vary greatly. At the same time, due to the many harmful organisms such as crayfish, toads, and frogs in the breeding ponds, the survival rate of the seedlings is extremely low, which greatly limits the development of this industry.
