Description

Biomass of Ulva spp. (Chlorophyta) causing ‘green tide’ and other seaweeds accumulated on shallow sea bottom in inner area of Hiroshima Bay was estimated by trawl-net and SCUBA surveys. Thirty-eight species of seaweed and seagrass was sampled, but Ulva spp. was dominant occupying 64-100 % in biomass of all samples. Ulva spp. was sampled most abundantly at the stations shallower than 5 m, and it was indicated that sea bottom with a gentle slope, and located offshore of sandy beaches or tidal-flats offers a suitable condition for Ulva growth.
