Circulating feeding type crayfish anti-escape culture pond

Abstract

The invention discloses a circulating feeding type freshwater crayfish anti-escape culture pond, and belongs to the field of aquaculture. Feeding rollers are mounted on the two sides of the top end of the culture pond correspondingly, and the rotating feeding rollers are cooperated with anti-escape plates, so that the situation that crayfish escape is effectively avoided; magnetic conveying belts sleeving the feeding rollers are matched with first guiding rollers, second guiding rollers and third guiding rollers to achieve circulation loop type conveying, magnetic bait particles fall on the magnetic conveying belts through discharging ports of a feeding box during feeding, the magnetic conveying belts continuously bring the magnetic bait particles into the culture pond, and water-soluble layers are dissolved after the magnetic bait particles meet water, rod-shaped baits are separated from iron sheet layers, sufficient magnetic bait particles are cyclically and slowly conveyed into a water body and then decomposed and diffused, the feeding time of the magnetic bait particles is prolonged, feed does not sink to the bottom too much, and the crayfish are helped to eat cleanly; the multiple magnetic conveying belts are distributed at intervals, the feeding uniformity is further improved, and the competition among the crayfish is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a circulation-feeding type freshwater lobster escape prevention culture pond. Background technique [0002] Aquaculture has a long history in our country, and the scale of aquaculture in our country is also very large. The aquaculture industry provides a large number of aquatic products such as fish, shrimp and crabs for the people of the country every year. With the continuous development of aquaculture, the scale of aquaculture continues to increase. Among them, lobster farming is a relatively popular industry in recent years. Freshwater lobsters widely live in waters such as freshwater lakes, rivers, ponds, ditches and rice fields. Benthic organisms, plankton and various aquatic plants are palatable bait, and their It has the characteristics of short growth cycle, high yield and strong adaptability to miscellaneous food, so it is especially suitable for artificial commerci...

Problems solved by technology

The higher the isolation net not only increases the installation cost and manufacturing cost, but also the hoarding or plastic film on the top of the isolation net increases the wind resistance of the isolation net and reduces the wind resistance of the isolation device. When the wind is strong, the isolation The net is blown down, causing economic losses; in addition, in the prior art, the feed is generally fed to the breeding area regularly by the farmers in the prior art to make the lobster grow. Fast, and difficult to disperse evenly in the water body, often causing competition among lobsters
