Spatial Variability of Reproductive and Size Characteristics of the Northern Mummichog (Fundulus heteroclitus macrolepidotus) Collected Near Municipal Wastewater Discharges

Abstract Northern mummichog (Fundulus heteroclitus macrolepidotus) have been widely considered to be suitable for environmental effects monitoring despite concerns of spatial variability observed in energy reserves and reproductive indices. In this study, temporal and spatial variability in gonadosomatic index (GSI), liversomatic index (LSI), and condition factor (K) were examined across two sites in 2006 and 10 sites (four …
