Mature fish feed heavily on other fish, with rainbow smelt being their preferred food.
Current threats to Cisco populations include nutrient-induced eutrophication, competition with invasive species like Rainbow Smelt (Osmerus mordax), warming summer water temperature and extended thermal stratification, and overharvesting (Latta, 1995; Hrabik, et al, 1998; Stockwell et al, 2009; Jacobson et al., 2012).
Saffron cod (95% FO) and rainbow smelt, Osmerus mordax, (55% FO) were most prevalent, followed by sculpins (9% FO).
She was interested in understanding how invasive rainbow smelt were affecting the ecology of lakes and mercury levels in predatory fish, such as lake trout, walleye and northern pike.
Among specific topics are the postglacial recolonization and the loss of anadromy in rainbow smelt from coastal Newfoundland, planning the management of Pacific salmon in a changing climate, modeling larval migration routes and spawning areas of Anguillid eels of New Zealand and Australia, detecting marine nutrient and organic matter inputs into multiple trophic levels in streams of Atlantic Canada and France, the status of diodromous fish species in the restored East Hammar Marsh in southern Iraq, and socio-economic and bio-political linkages in the management of tropical shad.
