Problems solved by technology

However, during the experiment, the indoor cultivation of jellyfish discs has always been a difficult point
The diameter of adult jellyfish can reach 2-3 meters, and the length of tentacles can reach 1 meter, but the diameter of its newborn disc is less than 1 cm, and its swimming ability is weak.
Its shortcoming is that the water flow produced by the glass tube is inhomogeneous, and there are often dead corners of water flow in the beaker. Once the dish enters it, there is no water flow to drive it and it is impossible to swim and ingest, resulting in obvious individual appearance in the dish culture. Differentiation
And during the culture process, with the growth of the dish, the inflated gas often enters the gastric cavity of the umbrella, causing the umbrella to shrink and die when the dish floats on the water surface, resulting in artificial errors in the research data

Embodiment 1

[0024] Embodiment 1 disc-shaped body culture bottle is used separately

[0025] The following is attached figure 1 , the structure of the jellyfish disc-shaped body culture bottle of the present invention is described, and it comprises bottle body 1, disc-shaped part 2, bottle body sealing cap 3, flat sealing cap 4 and electric roller bottle machine 7; Described bottle body 1 It is cylindrical, with hemispherical depressions 5 evenly arranged around it, and the ports at both ends of the cylindrical bottle body 1 are provided with external threads; The internal threads used in conjunction with the external threads at both ends of the body 1, the narrow mouth port protrudes in the shape of a bottle mouth, and is provided with external threads; The external threads are matched; the annular thread ring 6 has internal threads, and is matched with the external threads of the ports at both ends of the bottle body 1; The external thread of the bottle mouth matches.

Embodiment 2

[0028] Embodiment 2 Multiple culture flasks are used in series as a group

[0029] On the basis of the technical scheme of embodiment 1, in order to facilitate the research on the disc, usually the experiment will set up a control group, a sample group with different factors and a parallel group. The same culture environment is more conducive to the research on the disc, so this paper The annular thread ring 6 designed by the invention can be used as a connector to connect a plurality of culture bottles in series, such as figure 2 , that is, the two ends of the inner thread of the annular thread ring 6 can be connected with the narrow end of the disc-shaped part 2 at the same time; thereby achieving the purpose of using multiple culture bottles in series.

[0030] In order to prevent the dish-shaped bodies in different culture bottles from being poured out or mixed in other culture bottles artificially when taking the culture bottles connected in series, the present invention...

Embodiment 3

[0035] Embodiment 3 jellyfish disc-shaped body laboratory culture method

[0036] Utilize the laboratory cultivation method of the jellyfish dish culture device described in embodiment 2, concrete steps are as follows: form culture bottle by the mode of embodiment 2, add the seawater 200ml that temperature 20 ℃, salinity 30 are filtered in the culture bottle, Get the sauculus larvae just released, the umbrella diameter is about 4mm, put 10 sauculus larvae in each culture bottle, use two annular thread rings 6, place sieve silks at both ends respectively, and then put the above three The culture bottles are connected in series, as an experimental group, the culture bottles are placed on the electric roller bottle machine 7, the speed is set to 2 rpm, and the culture is started in a constant temperature light incubator, and Artemia nauplii are fed 3 times a day . Electric bottle roller machine 7 is suspended earlier when throwing something and feeding, unscrew annular thread ri...

Abstract

The invention discloses a jellyfish disc culture device and a method for using the same. The structure includes a culture bottle and an electric roller bottle machine. Both ends are detachably connected to the side cover, and there is a hole in the middle of the side cover, and hemispherical depressions are evenly arranged on the bottle body. During the specific experiment process, the dish can do floating movement with the low-speed and effective water flow inside the culture bottle , The cylindrical bottle body has no dead ends and inflatable tubes, which effectively avoids individual damage, and at the same time, the water body does not produce air bubbles, which can effectively prevent the bubbles from entering the gastric cavity of the disc-shaped body and rise up, reducing the mortality rate. The survival rate of the jellyfish dish is effectively improved, and the accuracy of the indoor research experiment is guaranteed. It is conducive to the in-depth study of disastrous and economic jellyfish, and has a wide range of uses in related research fields such as fishery resource utilization and ecological restoration.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding devices. In particular, it relates to a jellyfish disc culture device used in a laboratory and an application method thereof. Background technique [0002] Since the end of the 20th century, a large number of outbreaks of jellyfish have occurred in many parts of the world, which has brought huge impacts and losses on the ecological environment, fishery resources, mariculture, coastal industries and tourism. More than 100 people die from jellyfish stings in the world every year, 90% of fishing nets are damaged by jellyfish, and the annual economic loss reaches 265 million US dollars. There are mainly four types of jellyfish that appear in my country's coastal waters, including jellyfish, sand stings, white rosy jellyfish and sea moon jellyfish. Among them, only jellyfish is a fishery economic species, and the other three are disastrous jellyfish. In recent years, there have been ...
