對於河流現場，收集了河流兩側的累積計數。 有些網站僅從2011年至2016年抽樣一次，而其他網站則多次抽樣。 所有調查的平均貽貝密度範圍為0.19至2.86貽貝/平方米，對應於從102至3,276的場地估計豐度。
For the river site, cumulative counts from sides of the river were collected. Some sites were sampled only once while others were sampled multiple times from 2011-2016. Mean mussel densities across all surveys ranged from 0.19 to 2.86 mussels/m2, corresponding to site abundance estimates ranging from 102 to 3,276 mussels.
