Device for hatching artemia cysts by using circulating water

Abstract

The invention discloses a device for hatching artemia cysts by using circulating water. The device for hatching the artemia cysts by using the circulating water comprises a water warming case, and further comprises an inner tank and an outer tank, the middle portion and the upper portion of the inner tank are cylinders, the lower portion of the inner tank is a cone, the middle portion of the outer surface of the cone penetrates through and is fixedly connected on the bottom wall of the outer cylinder, a hole is formed in the upper portion of the inner tank, a screen is arranged on the hole, one end of a first water pipe is fixedly connected to the bottom, the other end of the first water pipe is connected to the water warming case, the first water pipe is provided with a valve and a first water pump, one end of a second water pipe is arranged between the inner tank and the outer tank, the other end of the second water pipe is arranged in the water warming case, a second water pump is arranged on the second water pipe, one end of a breathe pipe is arranged in the water warming case, and an air pump is arranged on the breather pipe. The device achieves the circulation using of bittern when artemia cysts are hatched, and the facts that temperature is adjustable and dissolved oxygen is operable in a hatching process are achieved. The device for hatching the artemia cysts by using the circulating water is simple and convenient to use and efficient.

Description

technical field [0001] The invention relates to a device for incubating Artemia eggs with circulating water. Background technique [0002] At present, there are many strains of Artemia eggs, and the differences among the strains are relatively large. For Artemia eggs of sensitive strains, any small factor may affect the final hatching rate. There are many factors that can affect the hatching rate of Artemia eggs. Based on the characteristics of each strain, it is found that temperature, dissolved oxygen, light and salinity are the main factors. Therefore, during the hatching process, if a constant temperature and sufficient dissolved oxygen can be guaranteed , a certain amount of light and salinity can greatly increase the hatching rate of Artemia eggs. At the same time, some Artemia hatchery farmers rely too much on and consume seawater resources, and the brine containing a large amount of chemicals and bacteria is discharged into the sea at the end of hatching, causing ce...

AI Technical Summary

Problems solved by technology

At the same time, some hatchery farmers of Artemia overly rely on and consume seawater resources, and the brine containing a large amount of chemicals and bacteria is discharged into the sea at the end of the hatching, causing certain pollution to the environment

At present, most of the devices used in domestic hatching take into account the influence of temperature and oxygen on the hatching rate. Some use the method of inserting air stones and heating rods in the water, but the air stones are not uniformly inflated, and the heating rods are not heated uniformly. Artemia larvae near the rod may be scalded to death due to high temperature; there is also a method of taking over the air from the lower end of the device, but does not consider the recycling of brine, etc.
