The Japanese eel (Anguilla japonica) is a fascinating fish with a long and mysterious journey. These sleek, eel-like fish spend most of their lives in the freshwater rivers and lakes of East Asia, but to reproduce, they embark on an epic migration across the Pacific Ocean to spawn in the Sargasso Sea, near Bermuda. After hatching, the tiny eel larvae, called leptocephali, drift back towards the coasts of East Asia on ocean currents, a journey that can take up to a year. Once they reach the coast, they transform into glass eels, transparent fish that migrate up rivers and into freshwater habitats.
Japanese eels are prized for their delicious flavor and are a popular delicacy in Japan and other parts of East Asia. They are often cooked in eel bowls (donburi) or grilled and served with a sweet and savory sauce. However, overfishing and habitat loss have led to a decline in Japanese eel populations, and they are now classified as a threatened species. Conservation efforts are underway to protect these amazing fish and ensure their future survival.
