Japanese authorities on Wednesday stopped highly radioactive water leaking into the Pacific Ocean from a stricken nuclear plant.
They used liquid glass to repair a broken reactor, which was the source of the leak.
Engineers have been battling to plug leaks from the tsunami-hit Fukushima plant since 11 March.
Radioactive iodine has been found in nearby seawater to be 4,800 times over the legal limit.
That has angered Japanese fishermen, who are sceptical about plant operator TEPCO’s assurances that the water is safe.
Ikuhiro Hattori, head of Japan’s fishing industry lobby, met with TEPCO chief executive Tsunehisa Katsunuma to call for an end to nuclear power.
His members fear they will not be able to find buyers for fish caught in the nearby Ibaraki prefecture.
The government has said it will consider compensating fishermen affected by the crisis.
