摘要：The Macrobenthos of a small tidal flat in the lower reaches of the Yodo River was investigated. Samples were collected from two sides of the flat, one bounded by a tidal creek and one by the main stream. Corbicula japonica, Neanthes japonica, N. succinea, Notomastus sp., Paraprionospio sp. and Grandidierella japonica were collected from the sediment. The average biomass was 16.40g/0.053m2 in the tidal creek and 15.22g in the main stream.
