RIKUZENTAKATA, Iwate Prefecture--Salmon were swimming upstream to spawn in rivers that were affected by Typhoon No. 19, which damaged or destroyed hatcheries and fishing spots in the city.

Iwate is the most productive salmon fishing prefecture on the main Honshu island, and now is the peak season for salmon runs.

Salmon with patchy patterns of red and black were seen going against the flow on the Yahagigawa river, a side stream of the Kesengawa river that runs through Rikuzentakata, and laying their eggs.

According to a fishery cooperative association in the city, salmon-catching areas near the mouth of the Kesengawa river were washed away by a flood caused by the typhoon, which made landfall on Oct. 12.

After a delay caused by typhoon damage, fishing nets were installed on the river on Nov. 2.
