Image Of the Day caption:
Northeast U.S. coastal waters are known for their productive fisheries, and alewife are a big food source for commercial species. WHOI biologist Joel Llopiz investigates the factors that affect the survival of alewife larvaeusing otoliths, tiny calcium carbonate deposits in fish heads. Alewife are one of six species that will be studied in the new Long-Term Ecological Research site. The LTER builds on data collected from the already established Martha's Vineyard Coastal Observatory to the north and the Ocean Observatories Initiative Pioneer Array to the south. It will be bolstered by collaborations with researchers from Maine to North Carolina.
Caption from WHOI News Release dated 03/01/2017:
Alewife (one of the two species of river herring) are anadromous fish that live in the ocean off the Northeast U.S. and return to lakes and rivers to spawn each year. They are a significant food source for commercially important species and are one of six species of forage fish that will be studied as part of the LTER project in order to understand their role in transferring energy up the food chain and in linking freshwater habitats with the coastal ocean.
