Fall and winter movements and activity level of the mummichog, Fundulus heteroclitus, in a tidal creek

Fall and winter movements and activity levels of Fundulus heteroclitus, the mummichog, were monitored in a Delaware tidal creek from September, 1973 to January, 1974. Fish either moved upstream into less saline waters or remained on station. As photoperiod decreased, activity levels at high salinity stations (17–29 o/oo) decreased, while activity levels at low salinity stations (1–21 o/oo) remained relatively high.
