Summary

Increased nutrient and sediment loading have caused observable changes in algal community composition, and thereby, altered the quality and quantity of food resources available to native freshwater mussels. Our objective was to characterize the relationship between nutrient conditions and mussel food quality and examine the effects on the fatty acid composition, growth and survival of juvenile mussels. Juvenile Lampsilis cardium and L. siliquoidea were deployed in cages for 28 d at four riverine and four lacustrine sites in the lower St. Croix River, Minnesota/Wisconsin, USA. Mussel foot tissue and food resources (four seston fractions and surficial sediment) were analyzed for quantitative fatty acid (FA) composition. Green algae were [...]

Purpose

Data were collected to better characterize the relationship between nutrient conditions and mussel food quality in the river corridor and within the four subbasins of Lake St. Croix, and investigate the relationship among seston and benthic food quality and the fatty acid composition, survival and growth of juvenile mussels in main channel versus lacustrine habitats of contrasting water quality.
