The St. Croix National Scenic Riverway (SACN) has been the subject of previous nutrient and mussel investigations; however, additional information is needed to support current mussel preservation activities and nutrient management initiatives. The proposed work will provide essential information to aid in our understanding of interactions between food quality, health, and survival of native mussels and water quality in the SACN by (1) characterizing current status of food resources available to native mussels, (2) experimentally investigating survival and growth of caged juvenile mussels, and (3) providing novel information on the relationship between water column and benthic food quality critical for survival of this group of threatened organisms.
