A kind of indoor temporary culture device and temporary culture method of red nematode as bait for fish fry opening

Abstract

The invention discloses an indoor temporary raising device and a temporary raising method for red nematodes as bait for fish fry openings, and relates to the technical field of red nematode temporary raising. The invention includes a high-level water tower, a U-shaped pool body, a drainage channel and a sump. The drainage channel is fixed at one end of the U-shaped pool body. A first partition is arranged between the drainage channel and the U-shaped pool body. Two partitions, several second partitions divide the U-shaped pool body into several temporary storage pools, the top surfaces of the first partition and the second partition are parallel to each other, and the top surface of the second partition is lower than the top surface of the U-shaped pool body, the difference is 8 ‑10cm range. The present invention can realize the water circulation through the combined use of the high-level water tower, the first water pump, the second water pump, the holding pond, the drainage channel and the sump, spread the red nematodes in the holding pond, and use a steel wire rake to stir and disperse them within a certain period of time. , to solve the problem that the red nematodes tend to form clumps when they are temporarily raised, which causes the temporary raising time and the survival rate of the temporary raising to be too low.

Description

technical field [0001] The invention belongs to the technical field of temporary cultivation of red nematodes, in particular to an indoor temporary cultivation device and a temporary cultivation method of red nematodes as bait for fry. Background technique [0002] Red nematodes, also known as water worms, red filarworms and red nematodes, are the open bait that many fish seedlings like to eat, and they are also the main bait for benthic fish such as snakehead, mandarin fish, sturgeon, eel and rice field eel . [0003] The red nematodes purchased in the fish fry breeding farm must first be temporarily raised to empty the contents of the intestinal tract, and then fed to the fry as bait. The holding time of the red nematode and improving its holding survival rate are technical problems to be solved by those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a kind of indoor temporarily raising device and temporarily ra...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of indoor temporarily raising device and temporarily raising method of red nematode bait for fish fry, which can be realized through the cooperative use of high-level water tower, first water pump, second water pump, temporarily raising pond, drainage channel and sump Water circulation, spread the red nematodes in the holding pond, and use a steel wire rake to stir and disperse them within a certain period of time, which solves the problem that the red nematodes are easy to form clumps when they are temporarily raised, causing the temporary holding time and the survival rate of the holding to be too low
