The ocean is open, and the city of Xiamen is also open. This is evident in the management of marine debris in Xiamen.
In order to improve the local governance system, Xiamen can break out of Xiamen Bay, focus on the future, focus on cooperation and exchanges at home and abroad, and launch many powerful initiatives leading the country.
In this issue of the "No. Reader", we went to the "Ecotoxic Toxicology Aquarium Hall" of the Ocean III to learn about a small fish with great ability - Qinglan.
Many people in Xiamen may not know that there is a very inconspicuous small bungalow next to the three whale dolphins on the university road, which has thousands of small and inconspicuous transparent fish.
It is called barley, the individual is small, the body length of the adult fish is generally only 3-4 cm, less than a bean sprout size.
Researchers at Ocean III said that it carries the burden of exploring global marine microplastic waste management research.
Known as "the white mouse in the water"
How do these inconspicuous little fishes relate to the global marine ecology problem?
“They are actually 'white mice in the water'. We hope to find out the effects of micro-plastics on marine life through experiments with these fishes, and look forward to establishing corresponding standards.†Chen Yizhe, Marine Science and Environmental Monitoring Technology Laboratory, Oceanic Institute The doctor explained.
On the wall of the humble little cottage, there is a sign: "Ecological Toxicology Aquarium". Although it is called the Aquarium, more accurately, it is actually a laboratory. The research on the influence of micro-plastics on fish has been carried out here for more than a year.
Microplastics, usually plastic particles with a particle size of less than 5 mm, are also visually compared to "PM2.5" in the ocean, and are currently a hot topic in marine ecological protection. In 2015, micro-plastic pollution was listed as the second-largest scientific issue in the field of environmental and ecological science research, and it is considered to be a major hidden danger affecting the marine ecological environment and even harming human health in the future.
It is understood that Xiamen is currently conducting research on the impact standards of micro-plastics on marine organisms, as well as monitoring standards for the characteristics of Xiamen Bay.
“Xiamen considers not only its own future problems.†Chen said that in the management of micro-plastic waste, Xiamen is first in China, and their research results will be monitored in the future for micro-plastics in other Gulf cities at home and abroad. Great reference.
Observing data through microplastics
According to reports, this humble little fish is rarely asked on weekdays. Unlike the coral restoration museum, which is home to tropical fish and is often visited by citizens, it feels very quiet and peaceful.
The Morning News reporter saw at the scene that the room here was emitting green and green light. Dozens of glass fish tanks were stacked on the wall layer by layer. The room temperature was maintained at around 25 °C throughout the year. The LED lights provided more than ten hours of illumination. .
The fish that swim in the glass jar are small and transparent. They don't look closely, and they can't even see that there are fish swimming inside. The only difference that can be seen in these dozens of fish tanks is the label attached to it, showing the different hatching times of the various batches of fish, as well as the micro-plastics of different density and particle size in seawater. “All other environmental factors are the same and the same,†the researchers said, in order to ensure that the observed data is due to changes in microplastics.
According to reports, this experiment needs more data, and the fish will stay here for a long time.
Although there is no colorful appearance, but the contribution is huge and the significance is extraordinary, these little fish should be thanked. The next time the citizens visit the three whale dolphins in the ocean, they may also visit the Ecotoxicology Aquarium.
LED strip lights have become increasingly popular in recent years due to their versatility and convenience. The market offers a variety of LED strip lights with different features, making them ideal for home, commercial or industrial use.
