We conducted a survey on the spawning migration of wild eels in Shizuoka and Kumamoto!

We conducted a spawning migration survey using pop-up tags on natural downstream eels in Shizuoka Prefecture on December 2, 2024, and in Kumamoto Prefecture on December 13, 2024.

In Shizuoka Prefecture, we set out by boat from Lake Hamana and released five individuals in an area approximately 700 meters deep.

In the Ariake Sea in Kumamoto Prefecture, we released three individuals in shallow water inside the bay.

This is the first time we have tried to collect data on eels migrating to the open ocean. We saw many dolphins from the boat!

We received cooperation from Ebisen Co., Ltd., the Fishing Shop BLUEJUNKIE, and the Kumamoto Prefectural Fisheries Research Center for this survey. Thank you very much.
