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 2003. Information on changes in fish catch over all years can be obtained from the Graphical Fish Database Browser.

 

• 21 fish collections were conducted using day electrofishing in period 3 only (Table 2.3).
  
• Water levels did not affect sample allocations (Table 2.3; Figure 1.3).
  
  
• All 21 fish collections were from randomly selected sites.
  
  
• Day electrofishing collections were conducted in backwater; main channel border, unstructured, and side channel border strata (Table 2.3).
  
  
• 2,563 fish were collected representing 45 species (Table 3.3).
  
  
• The LTRMP species total for Pool 13 from 1993 to 2002 was 83; no new species were collected in the 2003 season (Table 3.3).
  
  
• No species were collected that are Iowa-listed endangered or threatened species (Table 3.3).
