摘要

1970年7月至1971年5月，在弗吉尼亚州皮亚卡坦克河的7个站点每两个月捕获一次，包括41个物种的3417个标本。河流的数量丰度和物种丰度反映了物种特定迁徙的季节性格局，9月份数量丰度达到高峰，冬季海鱼数量减少。

Seasonality, abundance, and diversity of fishes in the Piankatank River, Virginia (1970–1971)

Bimonthly trawl catches at seven stations in the Piankatank River, Virginia, for the period July 1970 to May 1971 included 3417 specimens representing 41 species. Numeric and species abundance in the river reflected a seasonal pattern of species specific migrations with peak numerical abundance in September and a decline in marine fishes during winter.
