Description

Improved medaka breeding vat and incubation vat

[ technical field ] A

The utility model belongs to the technical field of fish culture technique and specifically relates to a modified medaka breeds jar and incubates jar.

[ background of the invention ]

Medaka is one of experimental fishes applied to the field of life science in recent years. With the continuous and deep research on the field of medaka genetics and developmental behavior, the use of medaka as a model animal has been increasingly studied worldwide in recent years. Under natural conditions, medaka is bred in batches in the morning, eggs are provided with a plurality of oil balls, filaments are arranged on egg membranes, and the medaka belongs to sinking eggs after being suspended behind maternal genital pores after egg laying. So the mother has the habit of rubbing the eggs on the attachments after the mother lays eggs. In the current period of medaka breeding in laboratories, zebrafish breeding jars are mainly used, and medaka breeding devices are specially used, but eggs gradually fall off after being hung for 2 hours behind a parent reproduction hole, so that difficulty is caused in collection of the fish eggs. In daily and commercial reproduction, scouring pad is used as attachment, but the scouring pad is not suitable for experimental conditions, impurities in folds are more, some excrement and feed are difficult to remove, and dead eggs are very difficult to remove, so that the survival of fish eggs is influenced.

The Chinese patent application: CN214962017U discloses an integrated breeding device for medaka with a visual back, which comprises a breeding water tank, a fish tank heating rod, an illumination device, an overflow drain pipe, a drain partition plate, a water adding and rain sprinkling pipe, a spawn collector, a feeder and a feeding sliding plate, wherein the feeding sliding plate can slide in the height direction of the breeding water tank, the feeding sliding plate is spaced from the bottom plate when reaching a lower sliding limit, the feeder is fixed above the breeding water tank, the illumination device is erected above the breeding water tank, the overflow drain pipe is arranged at the upper part of the left side wall, the drain partition plate is spaced from the left side wall, the bottom end of the drain partition plate is spaced from the bottom plate, and the drain partition plate and the overflow drain pipe are matched for draining. Its advantages are: the utility model discloses can provide comfortable living space for the parent fish, can not only supply illumination, regularly feed for the fish and eat and collect the ovum, can also supply water to heat, mend new water and blowdown, and adopt the way blowdown of overflow blowdown, can not disturb and frighten the parent fish, guaranteed the normal life and the reproduction of fish. However, the device ignores filaments on the medaka egg membrane, the medaka eggs are gradually dropped after being suspended in a parent reproduction hole 2 hours after being produced in batches in the morning, the device cannot timely collect fish eggs, and adult fish can swallow the fish eggs at the moment, so that the survival rate of the fish eggs is influenced.

In conclusion, there is a need for an improved medaka breeding tank and an improved medaka incubation tank which can not only enable medaka to lay and collect eggs normally, but also can collect the eggs in time by utilizing filaments on an egg membrane, prevent adult fish from eating the eggs, and provide a clean and safe incubation environment for the eggs.
