permit. The goal of this act was to slow down the over fishing of the
Japanese eel and control the number of eels being taken into captivity. In the future there is a law being placed that in December 2023 that makes fishing glass eels without a permit punishable with up to 3 years in prison or a 30 million Japanese yen fine. There have also been efforts made to stop the habitat loss of this species through the Nature-oriented river works. The high price and demand of this species means that there is also need for the Act on "Ensuring the Proper Domestic Distribution and Importation of Specified Aquatic Animals and Plants" that prohibits harvesting and culturing these eels without a permit that was put in place in 2020.

their migration. An eel at this stage in its life cycle is 6 cm long with an intense instinct to swim upstream. This instinct allows them to scale any scenario and attempt to make it to their permanent habitat. During this migration, the eels are not presented with many predators as they are not commonly preyed on during the eel's life cycle stage. This low number of predators could also affect the nocturnal nature of the eels during this time. They chose to swim upstream during the night hours and hide under banks and rockets of the river during the day. Two weeks into this migration, the eels develop a black coloring and metamorphosis from elvers to brown-stage eels to continue their journey.

due to the breeding habits. Scientists and farmers have never been able to breed an eel, so this species' agriculture relies heavily on their catch in their elver stage. A net is strewn across the rivers that these eels migrate up in the early autumn, and then they are transported to cultured ponds to grow to commercial size. The female eel grows to a much bigger size and has a longer life span than the male eel therefor; the cultured population is made up of 90% female eel. The heavy farming of this species has negatively impacted the conservation of the species; however, the production and consumption have not slowed.

environment as it relies significantly on the color of the water. The eels grow to around their adult size in this stage as well during this time, which is up to 57 – 60 cm for females and 35 cm for males. At 30 cm, the eels grow sexual organs for the first time and prepare to make their great migration.

Once these eels reach adulthood, they develop a silvery color under their skin. This change in appearance signaling that they are entering their last stage of life, the silver stage.

Another factor that is effecting the
Japanese eels is habitats loss. The coast is becoming a more preferred location for humans to live as the climate and pollution continues to worsen taking away from the habitat of these eels. On average from 1970s–2010s, 76.8% of the Japanese eels habitat is lost

The brown-stage, also known as the yellow stage, stage of the eel's life lasts for 5–10 years, and during this time, the eel feeds on worms and insects. The characteristics of this stage include a dull pigment with a grey, brown, and greenish top and white underbelly. This pigment is related to the

The culturing of eels was started in Japan in 1894 and has become the most significant eel culture industry in the world since. Japan is the biggest consumer and producer of eels generating approximately 70 - 90% of the eel population as of 1991. The farming of the
Japanese eel is challenging

The decline of the population of the
Japanese eel is also directly related to the strong connection that the eel's life cycle has with the temperature of the water. This species relies on this environmental signal to know when to migrate in and out of their fresh water habitat; thus, the change in

The discovery of the
Japanese eel breeding location was a new finding in 1991 when R.V. Hakuho Maru performed a research cruise. Before this research cruise, little was known about how eels breed, and there is still so much to learn as these eels remain a mystery to many scientists. Until the late

In the case of the
Japanese eel's spawning is likely affected by the north–south shifts of a salinity front created by an area of low-salinity waters resulting from tropical rainfall. The front is thought to be detected by the adult spawning eels and to affect the latitudes at which they spawn. A

oil is stored in the muscles of the eels and is approximately 20% of their body mass. Once the appropriate content of the oil is reached, the eels stop feeding. During the autumn and generally on the last quarter of the moon, the eels migrate downstream to the center of the pacific.
