Closing the loop: characterizing habitat requirements, movements, and life stage linkages of river herring in Massachusetts watersheds

Summary

The PIs propose a comprehensive project to explore the life history requirements of emigrating river herring in freshwater, riverine, and estuarine environments. The project proposes to 1) characterize density, growth, and mortality of juvenile river herring in estuaries and upstream lakes, 2) assess age, size, and timing of juvenile river herring during emigration from freshwater to estuarine habitats, and 3) evaluate relationships between spawning adults, juvenile abundance and timing of movements to identify conditions that promote growth and survival.
