A New Type of Indoor Sturgeon Open Fry Cultivation Device

Abstract

The patent of the present invention is a new indoor sturgeon fry cultivation device, including an inflatable pipe, a water inlet pipe, a water level pipe, a continuous feeding device and an incandescent lamp connected to the cultivation chamber. Between the bottom of the cultivating chamber and the gas-filled pipe, a baffle plate with micro-holes is fixedly installed, and one end of the edge of the cultivating chamber is installed with a water inlet pipe and three continuous feeding devices. The invention adopts the method of microporous oxygenation and is separated from the water inlet pipe, so as to ensure sufficient dissolved oxygen in the water body and avoid the problem of hypoxia and death of fish fry due to insufficient water inlet. The invention utilizes the phototaxis of sturgeon fry, installs an incandescent lamp on the edge of the cultivation chamber, and can gather most of the fry together. At the same time, a continuous baiting device is set up next to the incandescent lamp, which can automatically and continuously feed the fry within a certain period of time to ensure that the fry can take in enough bait, and effectively prevent the fry from biting and dying due to hunger. It fully guarantees the nutritional needs of the fry and reduces the labor cost at the same time.

Description

Technical field [0001] Technical Field The present invention relates to aquaculture farming, in particular, to new interior opening sturgeon fish cultivation apparatus. Background technique [0002] After the fry just hatched, they do not eat immediately, but after a period of flowing water holding culture, and then only in a suitable environment, eating their food palatability, we would have called this fish opening, due to the fry often influenced by environmental and food in the opening process, so fish cultivation in the process of opening attracted widespread attention. [0003] Currently opening sturgeon fry rearing system most of the stream basin (basin), although the timely exchange of culture water, but there are also many deficiencies. As cultivation process, if the water shortage will result fry hypoxia; early opening of sturgeon fish bait is typically liquid and is pulverized red worm bait form after mixing with water, and is generally fed manually time, which is pres...

AI Technical Summary

Problems solved by technology

If there is a shortage of water during the cultivation process, it will lead to hypoxia in the fry; the bait in the early stage of the sturgeon fry is usually a liquid form of red nematode crushed and mixed with water, and it is usually artificially fed at regular intervals, which will exist. The bait is lost with the water body, the bait feeding is uneven, and the bait feeding time is short, so it is impossible to ensure that most fish can eat enough bait in time, resulting in malnutrition, mutual bite, death and other phenomena in the fry, which affect the survival of the fry rate and growth performance
