Thousands of tons of dead sardines wash ashore in northern Japan
The sardines and some mackerel washed ashore in Hakodate on Japan’s northernmost main island of Hokkaido on Thursday morning, creating a sliver blanket along a stretch of beach about a kilometer (0.6 mile) long. Takashi Fujioka, a Hakodate Fisheries Research Institute said the fish may have been chased by larger fish, become exhausted due to a lack of oxygen while moving in a densely packed school, and were washed up by the waves.

Coastal Rivers Lacking Steelhead
After the January storms provided the flushing and scouring our coastal rivers desperately needed, anglers were thinking and hoping the winter steelhead would be there. Up and down the coast, well known steelhead rivers are not seeing the numbers we're accustomed to. This same scenario happened a couple years ago, but the fish finally showed up. And that will more than likely be the case again this year. But with the calendar now saying February, it's getting a little more nerve racking.

The cause of death is almost certainly acute Aspergillosis, a respiratory tract infection caused by a fungus commonly found in soil, dead leaves, moldy grain, compost piles, or in other decaying vegetation. Wildlife managers say the die-off seems to have stopped, likely due to the fungus source no longer being available.
