Description

Mandarin fish domesticates and throws feeding device with fodder

Technical Field

The invention relates to the technical field of aquaculture, in particular to a feed feeding device for mandarin fish domestication.

Background

The mandarin fish, also named mandarin fish, flower crucian and the like, has tender meat, no muscle bones and delicious taste, is a famous and precious variety in freshwater economic fishes in China and is deeply loved by consumers. In recent years, the mandarin fish industry in China develops rapidly, and the yield is as high as 37.7 ten thousand tons according to the yearbook of the fishery in 2021 years. The mandarin fish cultivation includes traditional cultivation and feed cultivation. The traditional method for breeding and feeding live bait fishes or iced fresh bait fishes has the defects that the breeding cost of the bait fishes is high, the bait fishes carry parasites and germs, and the iced fresh fishes have the problems of fat oxidation rancidity, protein putrefaction and the like caused by improper fresh keeping, so that diseases are caused. Therefore, feed cultivation is a future development direction, live fishes and iced fresh fishes are comprehensively replaced, the situation that the cost is high, diseases are more and death is large in the traditional bait fish mandarin fish cultivation is turned, and the aims of quality improvement, efficiency improvement, cost reduction, income increase and green cultivation are achieved.

The key link of mandarin fish feed cultivation is domestication and food transfer. At present, the mode which is mostly adopted is to hang net cages in a deep water area of a pond for intensive domestication and food conversion of compound feed, and the compound feed is cultured to about 2 specifications and is put into the pond for adult fish culture. The net cage hung in the deep water area of the pond has the advantage that the mandarin fish fries which are used to adhere to the wall, sink to the bottom and are not movable due to the dragging of the net cage can be prevented from dying in large quantities. The domestication of mandarin fish fry is realized through dynamic fluctuation of feed in a water pipe flushing device in fixed position to simulate live fish bait.

The mandarin fish fries without domestication and food transfer are low in price, the mandarin fish fries after domestication and food transfer are far higher in price than the mandarin fish fries without domestication, and the domesticated mandarin fish fries are the precondition for realizing the green and healthy cultivation of the mandarin fish compound feed. During domestication, some farmers usually force mandarin fish fries to eat feed in a hunger mode, and because mandarin fish are violent in nature and have the phenomena that large fish eat small fish and eat two fishes after hunger, the method is adopted, the survival rate of the mandarin fish fries is not high, and the income is influenced. And some farmers adopt a method of gradually reducing live bait fish and increasing the feeding of compound feed. The process is completed under the guidance of a flushing signal, and the mandarin fish is manually fed in a fixed time (such as dark in the morning and evening), so that the mandarin fish fries are in a full state, and the mandarin fish fries are bred into a habit of eating feed.

The siniperca chuatsi likes shadows, the ingestion of the siniperca chuatsi is greatly influenced by light intensity factors in a natural state, the ingestion behaviors are mostly expressed as circadian rhythm changes, generally, the ingestion activity is strong in dusk or dawn, and the ingestion activity is weak in daytime, so that the siniperca chuatsi needs to be domesticated by a certain time and scientific means, the ingestion habit of the siniperca chuatsi is changed to a certain extent, and the siniperca chuatsi can also be normally ingested in daytime.

In addition, the mandarin fish fries are usually distributed in the cultivation box in a dispersed and clustered (clustered) manner, and the fed feed cannot be accurately fed to the positions of the mandarin fish groups even though the water flow of the flushing pipe flows, so that the mandarin fish fries in the regions where the feed is not fed or the corners of the net box cannot be sufficiently fed. In the existing domestication process, after the feed is manually thrown out, part of the uneaten feed is soaked in water for ten minutes, food calling components, nutrients and other additive components in the feed are dissolved in the water, the mandarin fish refuses to eat the feed, the feed waste is caused, the water quality is polluted, and meanwhile, the domestication rate and the survival rate are influenced due to the closed mouth of the mandarin fish fries which do not eat the feed for a long time.
