Status and Management of Mississippi River Fisheries - H.L. Schramm Jr.
Table 1: Distribution and abundance of fishes in the headwaters (HW), upper (UMR), or open river (OR) segments of the Mississippi River. Fish are resident in the Mississippi River unless noted otherwise (Residence). Data were compiled from Fremling et al. (1989), Baker et al. (1991), Pitlo et al. (1995), and Warren et al. (2000). Fish categorized as strays by Fremling et al. (1989) and marine fishes collected only in the lower 150 km of the Mississippi River are excluded. Backwater dependent or riverine dependent indicates those taxa that are dependent on backwater or riverine conditions to complete their life cycle. Probable zone is the area of the river from which the fish have been or are likely to be collected.
