Connecticut lakes without landlocked Alewife had larger average zooplankton size and were dominated by large Daphnia spp. and calanoid copepods such as Epischura nordenskioldi and Diaptomus minutus, and the cyclopoid copepod Mesocyclops edax. Landlocked Alewife lakes were dominated by the cladoceran copepod Bosmina longirostris and the copepods Cyclops bicuspidatus thomasi and Tropocyclops prasinus.

Alewife has been shown to cause thiamine deficiency and, consequently, early mortality syndrome (EMS) in populations of alewife predators. EMS and its adverse effects on recruitment and fish populations is welldocumented for Atlantic salmon (Ketola et al. 2000)

Using time-series data for various fish populations along with change point regression analysis, scientists concluded that predation of larvae by alewife (Alosa pseudoharengus) likely contributed to the decline of yellow perch (Perca flavescens), deepwater sculpin (Myoxocephalus thompsonii), burbot (Lota lota), Atlantic salmon (Salmo salar), lake trout (Salvelinus namaycush), and emerald shiner (Notropis atherinoides).
