Abstract

Mysid shrimp are small crustaceans that are of particular importance in estuaries due to their role in nutrient subsidies and their importance in the diet of juvenile fishes. Despite their importance, they are typically undersampled relative to other zooplankton taxa. High abundances of Neomysis americana have been documented in the Damariscotta River estuary (DRE), Maine in late summer. While their summer abundance and small-scale diel migration behavior has been well described in the DRE, deta...

Additional description: These data were collected in the Damariscotta River estuary in Walpole, Maine. Environmental parameters were measured using a YSI-EXO multi-parameter sonde. Environmental measurements were collected approximately 0.5 m above the substrate and therefore, represent bottom-water measurements. Zooplankton were collected from midwater using an 80 micrometer mesh net. Mysid shrimp were collected just above the substrate with a 1000 micrometer mesh net.
