Pool 13, Upper Mississippi River 2001 Fish Collection Summary

This report is a bullet summary of the Long Term Resource Monitoring Program's (LTRMP)fish collection efforts conducted by the Bellevue Field Station on Pool 13, Upper Mississippi River during 2001. Information on changes in fish catch over all years can be obtained from the Graphical Fish Database Browser.

• 486 fish collections were conducted using 10 gear types (Table 2.3).
  
  
• Water levels did not affect sample allocations (Table 2.3; Figure 1.3).
  
  
• Of the 486 fish collections, 438 were from randomly selected sites. Forty-eight collections were made at fixed sites.
  
  
• Backwater; main channel border, unstructured; and side channel border strata received the most sampling effort (Table 2.3).
  
  
• 46,624 fish were collected representing 66 species and 1 hybrid (Table 3.3). This total includes 167 unidentified buffalo (Ictiobus sp.) less than 150 mm long and 8 unidentified redhorse (Moxostoma sp.).
  
  
• The LTRMP species total for Pool 13 before the 2001 season was 84; one new species was collected: freckled madtom (1) (Table 3.3).
  
  
• Four bluntnose darters and one freckled madtom were collected that are Iowa-listed endangered species (Table 3.3).
  
  
• Four western sand darters were collected that are Iowa-listed threatened species (Table 3.3).
  
  
• Twenty-three pugnose minnows were collected that are an Iowa-listed species of special concern (Table 3.3).
  
  
• Other species that were collected and are noted as uncommon, rare, or probably strays from tributaries (Pitlo et al. 1995) in Pool 13 were black buffalo, central mudminnow, fathead minnow, goldeye, green sunfish, Mississippi silvery minnow, quillback, sand shiner, slenderhead darter, smallmouth bass, stonecat, and white sucker (Table 3.3).
  
  
• Mean catch-per-unit-effort and standard error for fish collected by gears using stratified random (Tables 4.3-12.3) and fixed-site sampling (Tables 15.3-21.3) for each stratum are shown.
  
  
• Length distributions for selected species of fish are shown in Figures 2.3 to 19.3.
