The impact of current marine pollutionWith the intensification of Japan's nuclear pollution and the pollution of various microplastics and heavy metals, it continues to threaten the entire marine ecology. At the same time, it is devouring our dining table step by step, endangering the health of mankind and future generations.
-
Plastic pollution
Microplastic particles are pervasive, threatening marine ecology and human health
-
Heavy financial pollution
the accumulation of the middle layer of the food chain, destroying the marine ecological balance, causing harm to the human ecology, especially nerve system damage and various liver and kidney diseases.
-
Radioactive pollution
The radioactive substances contained in nuclear sewage can cause direct harm to marine organisms, which may cause genetic mutations and chromosomal distortions of marine organisms, thus causing food safety and drinking water safety risks.

19 species of freshwater eels
There are 19 species of freshwater eels around the world, which are typical migratory fish. They grow in stages such as willow eels, glass eels, black eels, yellow eels, silver eels, etc. They grow and develop in freshwater. As adults, they swim back to the deep sea to lay eggs every year from September to December.
Eels' preferred environment
Eels like to live in clean, warm and pollution-free waters. They have extremely high requirements for aquaculture water quality and water temperature. They are known as "the purest aquatic organism in the world", "ginseng in water" and "soft gold in water".
Vascular cleaner
The fish protein of eels can reach more than 50%, and the proportion of high-density lipoprotein that is regarded as an "vascular scavenger" reaches 60.2%-66.1%, which is conducive to the cardiovascular and cerebrovascular health of the human body. At the same time, it is rich in a variety of vitamins and nutrients such as unsaturated fatty acids. It is a recognized as a precious edible fish species.

From food on the table to endangered species
Eels have lived on the earth for 60 to 70 million years, but due to pollution and overfishing, the supply of eels has decreased sharply in recent decades. Since 2016, Japanese eels have been classified as endangered by the International Union for Conservation of Nature.

Artificial incubation technology of eel seedlings
At present, all seedlings that are the source of eel farming come from natural fish fry. In recent years, due to the continuous deterioration of the eel fry growth environment and overfishing caused by Japan's nuclear pollution and sea discharge, the catch has been significantly reduced, and ensuring the seedlings needed for breeding has become a problem. Artificial incubation technology of eel seedlings has been studied for a long time in various countries around the world. Hokkaido University, Japan Aquatic Research Institute and Kinki University have successfully cultivated artificial incubation eel seedlings one after another, but at this stage, they are still facing high costs and difficult to promote them on a large scale.
