Indoor temporary rearing device and method for fry opening bait red worms

Abstract

The invention discloses an indoor temporary rearing device and method for fry opening bait red worms, and relates to the technical field of red worm temporary rearing. The device comprises a high level water tower, a U-shaped pond, a drainage channel and a water collecting pond. The drainage channel is fixed to one end of the U-shaped pond, a first partition plate is arranged between the drainagechannel and the U-shaped pond, a plurality of second partitions are fixedly arranged inside the U-shaped pond, the U-shaped pond is partitioned into a plurality of temporary rearing ponds through themultiple second partitions, the top faces of the first partitions and the second partitions are parallel, the top faces of the second partitions are lower than the top face of the U-shaped pond, and the difference is within the range of 8-10 cm. Due to cooperative use of the high level water tower, a first water pump, a second water pump, a temporary rearing pond, the drainage channel and the water collecting pond, water circulation can be achieved, red worms are laid inside the temporary rearing pond, a steel wire rake is used for stirring and dispersing within a certain period of time, and the problems that when red worms are reared temporarily, block masses are easily formed, the temporary rearing time is short, and the temporary rearing survival rate is excessively low are solved.

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...

AI Technical Summary

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
