The Long Island Sound population of Crassostrea virginica, the Eastern oyster, has fluctuated historically, but remains an important fishery through aquaculture efforts. During this study oyster trophic resources were examined by several methods to investigate food availability for C. virginica. Seasonal community composition and abundance of phytoplankton were studied along with oyster glycogen during 2009 and 2010 in coastal Connecticut, USA embayments and tidal rivers. Phytoplankton communities, temperature and salinity presented typical seasonal patterns and ranges. Appropriately sized chlorophyll-a-containing particles always were available for oyster consumption. Availability of sufficient food was further supported by the analysis of oyster glycogen, as glycogen is a proxy for nutritional status in oysters. Glycogen measured at the beginning and end of quiescence also indicated minimal consumption of energy during the overwintering period when oysters do not feed appreciably (≤6°C). Although not identical, stations were able to support oysters similarly. While the appropriate trophic resources were available, it is imperative that aquaculture efforts continue to maintain or increase harvests of oysters from Long Island Sound.
