                        FISH TREND ANALYSIS DATA                               

Annual fish monitoring on the Upper Mississippi River System (UMRS)            
was implemented in 1990 under the Long Term Resource Monitoring Program        
(LTRMP).  Some preliminary sampling was conducted during 1989 to test          
sampling methods in Pools 8, 13 and 26; however, these data are best           
viewed as developmental data that are less useful for routine trend            
analysis.                                                                      

From 1990 through 1992, all fish sampling was conducted at subjectively        
chosen permanently fixed sampling sites within each aquatic area.              
Each site consisted of a pair of sampling locations separated by about         
50 meters (occasionally separated by as much as 200 meters).  In the           
original LTRMP fish sampling design, these pairs of sampling locations         
within fixed sites were considered replicates for the site and for the         
aquatic area.                                                                  

A statistical review of the sampling program was planned and conducted         
during 1992, critically examining the original LTRMP fish monitoring           
design and considering design alternatives.  The final report from this        
review (Gutreuter 1993) is available by request from the UMESC.                

A second statistical review of the sampling program was planned and            
conducted during 2001, critically examining whether sampling efficiencies      
could be gained.  The final report from this review                            
(Ickes and Burkhardt 2002) is available by request from the                    
Upper Midwest Environmental Sciences Center.                                   

As a result of the 1992 statistical review of the LTRMP fish monitoring        
program, major procedural changes were implemented in 1993.                    
The LTRMP Fisheries Component adopted a stratified random sampling design,     
with aquatic areas serving as strata.  Spatially randomized sites, with        
proper independent replication within strata, are currently sampled.           
Subjectively chosen permanently fixed sites have been retained in              
tailwaters (which are too small to permit meaningful replicated random         
sampling) and at a few sites of special interest (having historical            
occurrences of endangered species, associated with                             
habitat restoration projects, etc.).                                           

The 2001 statistical review resulted in minor procedural changes that          
were implemented in 2002.  Specifically, four gears were removed from the      
sampling design (night electrofishing, seining, tandem fyke nets, and          
tandem mini fyke nets).  Thus, beginning in 2002, data associated with         
these four gear types are neither available from nor collected by              
the program.  Please review Ickes and Burkhardt (2002) for details             
regarding this change in procedure.

Use of LTRMP Trend Data for Fish Monitoring                                    

The sampling design for fishes is sufficiently complex that all potential      
users of these data are strongly encouraged to read and understand the Fish    
Monitoring section of the LTRMP Procedures Manual (Gutreuter et al. 1995),     
which describes both historical and current procedures, before undertaking     
any analysis or interpretation of data.  This document is accessible

                                   SUMMARY                                     

LTRMP Fish Sampling Design                                                     

The LTRMP conducts annual monitoring of fishes in six study reaches of the     
Upper Mississippi River System:  Navigation Pools 4, 8, 13 and 26, and an      
unimpounded reach near Cape Girardeau, Missouri, on the Mississippi River; and 
La Grange Pool on the Illinois River.  The LTRMP will continue to expand fish  
monitoring beyond these six study reaches, and welcomes participation by other 
agencies and groups that could sample other areas using the LTRMP sampling     
protocol.                                                                      

The LTRMP conducts highly standardized fish sampling in main channel border,   
tailwater, side channel, contiguous (to the main channel or side channels)     
backwater, and impounded aquatic areas in each study reach.  Sampling is       
conducted using electrofishing, hoop netting, fyke (trap) netting, seining,    
and trawling.                                                                  

Fish sampling is conducted from June 15 through July 31, August 1 through      
September 14, and September 15 through October 31.  Prior to 1993, each fixed  
site was sampled once (two "replicates" per site) during each time period.     
Beginning in 1993, independently distributed sampling sites have been sampled  
within a combination of stratum and time period.                               

Gears and use of gear are highly standardized within the LTRMP.  See the Fish  
Monitoring section of the LTRMP Procedures Manual (Gutreuter et al. 1995) for  
details.                                                                       

Data Composition                                                               

Principal fish data collected are species composition, relative abundance      
(catch-per-unit-effort) and length distribution of catches.  Subsamples from   
a few species (particularly freshwater drum) are collected for age             
determination, growth analysis, and examination of food use.  The LTRMP also   
collects considerable site-specific data on environmental conditions and       
quality assurance measures.  LTRMP data and their interpretation are described 
in Gutreuter et al. 1994.

LENGTH
Numeric field to identify the lower bound of the length group to which a fish
record belongs (measured in millimeters). A length group is defined as all
fish of a particular species for a collection which fall within the GRP WIDTH
(group width) range. See the GRP WIDTH description.




T F S
Alphabetic code to identify system used for length measurement:
Following are valid codes:
T or Blank = Maximum total length measurement; distance from anterior-most
extreme of head (jaw closed) to most distant lobe of caudal fin (lobes
compressed to achieve maximum length)
F = Fork length; distance from anterior-most extreme of head (jaw closed) to
fork of caudal fin (tip of median fin rays)
S = Standard length; distance from anterior-most extreme of head (jaw
closed) to caudal peduncle (posterior margin of hypural bone)




GROUP WIDTH
Numeric field to record the range in centimeters of a
a length group from within which fish were enumerated or bulk-
weighed. For example, if LENGTH is 40 and GRP WIDTH is 1, then
the range of lengths for the fish representing this fish record would be
from 40 through 49 millimeters.
This field should be blank for fish that are unmeasured or individually
measured to the nearest 1 millimeter.




FISH COUNT
Numeric field to record counts of fish represented by
the row of data. Fish Count is 1 for all individually measured
lengths and weights and รท1 for bulk counts. For example, if a
particular fish was measured to the nearest 1 millimeter, then Fish
Count is 1. If just one fish of a particular length group is
encountered during length group enumeration, then Fish Count is
also 1 for that length group. However, if 10 fish of a length
group are encountered during group enumeration, then Fish
Count is 10.




IND/AGG. WEIGHT
Numeric field to record individual or aggregate weights
(in grams). Aggregate weights are distinguished by the presence
of a Group Width value. Weights are measured only for special purposes.




PATHOLOGY CODE
Special information not routinely collected during standardized
monitoring activities.
Represents LTRMP fish health/pathogen codes as follows:
0 or blank = No visible abnormality
1 = Parasite
2 = Skeletal abnormality
3 = Tumors
4 = Injury
5 = Skin/fin/eye
6 = Other




SUBPROJECT CODE
Two byte length alphanumeric field containing special information
not routinely collected during standardized monitoring activities.
Represents data needed to interpret data in the USER DEFINED FIELDS
as follows:
Following is a description of what these two bytes represent.
Byte 1:
1 = Aging structures (otoliths, scales, etc.) collected, specimen bar code
2 = Stomach contents collected
3 = Both aging structures and stomach contents collected
0 = Continued from previous line
Note: When the above codes are used, the specimen bar
code number should be recorded in the USER DEFINED FIELDS.
Byte 2:
0 = Tag implanted, number follows in bytes 4-14, fish released
1 = Tag recovered, number follows in bytes 4-14, fish released
2 = Tag recovered, number follows in bytes 4-14, fish not released
3 = Tag scar visible, fish released
4 = Tag scar visible, fish not released
5 = Fin clipped, fin position follows in byte 14
6 = Fin clip recovered, position follows byte 14, released
7 = Fin clip recovered, position follows in byte 14, not released




USER DEFINED FIELDS
Twelve byte length alphanumeric field containing special information
not routinely collected during standardized monitoring activities.
Following is a description of what these twelve bytes represent.
Bytes 1-10: Specimen number (aging structure and/or stomach contents).
Byte 11: Fin clipping position.
-- or --
Bytes 1-11: Tag number.
Byte 12: Gill net mesh size code as follows:
1 = 4"
2 = 6"
3 = 8"
4 = 10"
-- or --
Byte 12: Number of seines or trawls




RECORDER CODE
Alphanumeric field to identify the LTRMP recorder responsible for recording of
this measurement sheet data. These codes are permanently assigned to LTRMP
staff at each station.




NUMBER OF FISH ON SHEET
Numeric field to record the total number of fish (sum of Fish Counts) recorded
on this Fish Measurement Sheet.




ORPHAN FLAG
Administrative field used to track orphan fish records.
Orphan records should no longer occur due to barcode usage.




BATCH NUMBER
Administrative field used to track keyed data batches.
