- •
We analyzed radiocesium data of monitored marine species during 2011–2015.
- •
Radiocesium concentrations in demersal fish decreased, even within 20 km from the FDNPP.
- •
Four samples (0.05%) exceeded the Japanese limit of 100 Bq kg−1-wet in 2015.
- •
Cs-137 in fish inside and outside of the FDNPP port decreased exponentially in 2012–2015.
- •
Pilot-scale fishing in Fukushima Prefecture target more areas and species.
