Filtration Rates of the Zebra Mussel ( Dreissena polymorpha ) on Natural Seston from Saginaw Bay, Lake Huron

Abstract

ABSTRACT. Filtration rates of the zebra mussel (Dreissena polymorpha) on natural seston from two different regions in Saginaw

Changes in the Freshwater Mussel Community of Lake St. Clair: from Unionidae to Dreissena polymorpha in Eight Years

“…To estimate filtration capacity of the D. polymorpha population in 1994, the filtration rate of D. polymorpha was assumed to be 16 mL mgAFDW-1 h-1 (Fans low et al 1995). This rate represents a mean value for rates determined under a wide range of temperature and seston concentrations in Saginaw Bay, Lake Huron over a 2-year period and compares favorably to rates reported for D. polymorpha by others (see Table 4, Fanslow et al 1995). If we then further assume that D. polymorpha filters 17 h d-1 (Walz 1978a) and ash free dry weight is 88% of dry weight (Nalepa et al 1993), the filtration capacity of the D. polymorpha population was 747 L m-2 d-1 in 1994.…”

Remote sensing of biotic effects: Zebra mussels (Dreissena polymorpha) influence on water clarity in Saginaw Bay, Lake Huron

“…3k) and late summer 1993 (Fig. 3f) may correspond to cyanophyte blooms in Saginaw Bay (Gardner et al 1995;Fanslow et al 1995). Blooms of Microcystis were observed again in 1994 in Saginaw Bay and in western Lake Erie during 1995 (Budd et al in press).…”

The effect of temperature and body size on filtration rates of Limnoperna fortunei (Bivalvia, Mytilidae) under laboratory conditions

“…The same authors, in 1992, analyzing the impact of pollutant material in suspension concluded that the water temperature played a minor role on the filtration rates, and that the amount of material in suspension was more important in modulating filtration. Fanslow et al (1995), studying the same species in the Saginaw Bay (Great Lakes region), concluded that the maximum filtration levels were probably associated with the temperature, although indirectly, through a decrease in seston and consequent increase in the filtration rates. On the other hand, Aldridge et al (1995) did detect a negative relationship between the temperature and filtration rates in D. polymorpha, with filtration rates at 20-24ºC being significantly higher than at 28-30ºC.…”
