Japanese Fly Fishing Association plants 10,000 fertilized eggs using Whitlock Vibert boxes purchased from FFI.
Recently JFFA, a Japanese affiliate club of Fly Fishers International, organized the annual fertilized eggs plant event. Precisely, Tohoku Branch of JFFA, “JFFA Mutsu”. It was a beautiful day in December with 46 °F ambient and 39 °F water temperature and no wind.
Followed the previous year, They planted egg boxes in Mano River and Uda River located in Fukushima Prefecture. These rivers were damaged fish habitat by the Great East Japan Earthquake in 2011.
They placed 20 Whitlock-Vibert boxes purchased from FFI filled with 10,000 fertilized eggs came from these rivers. These boxes are used to enhance fish stocks in the wild through egg planting.
In the old days, a lot of big Yamame was caught, so these rivers are excellent and healthy rivers that support healthy fish. We collect boxes every two weeks for observations. Recently, due to global warming and less snow, they are predicting that it can be completed in late February.
Yamame trout is native fish in Japan and they have interesting habits. After birth, almost of female Yamame grow up in the streams for one year and several months. Then female Yamame goes to the sea in spring, consumes a lot of foods for one year. But most male Yamame remain in the original streams and become mature male Yamame. So most female fish are larger but most adult male Yamame is small.
