Feed feeding device for mandarin fish domestication

Abstract

The invention provides a feed feeding device for mandarin fish domestication. The feed feeding device comprises a floating body, a shading tent, a feeding machine, a water injection assembly, a collection filter screen, a base, a driving assembly and four framework assemblies. The shading tent, the water injection assembly and the feeding machine are designed on the floating body, after the shading tent covers the floating body, the light intensity at dawn or dusk can be simulated, the water injection assembly injects water into the operation opening to stimulate mandarin fish fries to snatch food, the feeding machine can throw feed into the operation opening, and therefore remote feeding can be achieved; and the automation of daily management of mandarin fish domestication is improved. Moreover, due to the design of the collecting filter screen, the base, the driving assembly and the framework assemblies, part of feed which is not eaten in the water can be collected, so that waste of the feed is effectively avoided, and the situation that the water is polluted due to the fact that the feed is soaked in the pond water for a long time is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a feed feeding device for mandarin fish domestication. Background technique [0002] Mandarin fish, also known as sweet-scented osmanthus fish, crucian carp, etc., has tender meat, no intermuscular spines, and delicious taste. It is a famous and precious species among freshwater economic fish in my country, and is deeply loved by consumers. In recent years, my country's mandarin fish industry has developed rapidly. According to the 2021 Fishery Yearbook, the output is as high as 377,000 tons. Mandarin fish farming is divided into traditional farming and feed farming. The disadvantages of traditional breeding and feeding live bait fish or chilled bait fish are that the cost of bait fish is high, and they carry parasites and germs, and there are also problems such as fat oxidation and rancidity caused by improper preservation of chilled fish, which lead to disease. happened. ...

[0006]In addition, mandarin fish fry are usually distributed in scattered clusters (groups of groups) in the breeding box. Although the water flow of the flushing pipe is flowing, the feed cannot be accurately fed Feed to the location where the mandarin fish school is located, which will cause the mandarin fish fry in the area where the feed is not sprayed or at the corner of the cage to eat insufficiently
