Simulated effects of host fish distribution on juvenile unionid mussel dispersal in a large river

Abstract: Larval mussels (Family Unionidae) are obligate parasites on fish, and after excystment from their host, as juveniles, they are transported with flow. We know relatively little about the mechanisms that affect dispersal and subsequent settlement of juvenile mussels in large rivers. We used a three-dimensional hydrodynamic model of a reach of the Upper Mississippi River with stochastic Lagrangian particle tracking to simulate juvenile dispersal. Sensitivity analyses were used to determine the importance of excys… Show more

“…It is more difficult to link the distribution of mussels to the distribution of their host at a local scale, however, where other factors can affect the retention, growth and survival of mussels (e.g. dispersal by hydrodynamic forces, habitat quality; Morales et al, 2006;Daraio et al, 2010Daraio et al, , 2012. In East Arm, yellow perch is by far the dominant littoral fish and is a well-known host for E. complanata (Matteson, 1948).…”

“…In the situation examined here, the effect of bottom turbulence ( u * κ) was larger than the settling of the glochidia ( w s ; i.e., Rouse numbers, R ≤ 0.1), which has also been observed for larval settlement in laboratory flow chambers (Hendriks et al 2006). This result likely applies to other small organisms and particles with low excess density and w s in turbulent waters with , such as river plankton, fine particulate organic matter, and juvenile unionid mussels after they detach from their host fish (Cushing et al 1993; Daraio et al 2010a, 2010b). However, turbulence appears to have less of an effect on the dispersion of larger macroinvertebrates, such as blackfly larvae, with higher excess density and w s whose R > 1 in similarly turbulent flows (i.e., u * = 0.05 m s − 1 ; Fonseca 1999).…”

“…However, based on K z , any potential differences due to a 25‐cm difference in z r would diminish relatively quickly downstream, and given our low sample size ( n = 3 comparisons) it is difficult to draw definitive conclusions. Nonetheless, a hydrodynamic model of juvenile mussel dispersal in the Mississippi River suggested that a difference in z r can have a major effect on transport distance depending on local hydrodynamic conditions ( H ~ 2 m; mean annual Q ~2000 m 3 s − 1 ; Daraio et al 2010b).…”

“…() used a hydrodynamic model to simulate dispersal of juvenile mussels in the Upper Mississippi River, U.S.A. and found shear stress and substratum type, combined, could accurately predict settling into existing mussel bed locations. While only a portion of the life history of mussels, juvenile settling work is providing crucial information about how flow alterations can directly and indirectly optimise mussel bed formation and persistence (Daraio et al ., ,b, ). Juvenile settling work is also being used to inform models that simulate mussel population dynamics incorporating biotic interactions and abiotic conditions (Morales et al ., ).…”
