The abundance of each species in the trawls at each station is shown in Table 6. About the<br />

same quantity of fishes were caught at Station 7 (37.5%) and Station 9 (38,4%). White<br />

perch were most abundant at Station 9 and somewhat less abundant at Station 7. Blueback<br />

herring and bay anchovy were abundant at Station 7 and channel cat, blue cat, and<br />

hogchoker were abundant at Station 9. The catch at Station 10 was lower (24.0%), and was<br />

dominated by blueback herring and alewife. The growth of beds of submersed aquatic<br />

vegetation at Station 10 was noted as early as May 15, and may represent a major change in<br />

conditions in Pohick Bay. The number of species caught at each station was about the<br />

same: Station 7—16 sp., Station 9—15 sp., Station 10—17 sp..<br />
