Fisheries Database Browser

Fish data from the Long Term Resource Monitoring Program (LTRMP) are available through two database browser tools:

  1. Fisheries Database Browser, which provides the most complete access to raw data using the widest variety of query parameters. (below Query Fisheries Data)
  2. The Graphical Fish Database Browser, which provides summaries of the data as graphs and tables by species, gear, and location is available at
For fish metadata, read the Federal Geographic Data Committee/National Biological Information Infrastructure, Fish metadata page.

For fish component information, read the Fish Sampling Component Information Page that contains a description, history, and value ranges of the data.

Queries made using the Fisheries Database Browser are real time, it may take a few minutes to retrieve your results.
If you want to download the entire fish data set it is available here. Entire Fisheries Data Setdivision bar

Note: Coordinates are now servered as North American Datum 1983

The LTRMP fish collections began in 1989. Standard collections are made between June 15 and October 31 each year.

The LTRMP fisheries data is collected historically during three separate time period during the year:
Sampling Time Period (required)
Sampling Time Period 1 (June 15th to July 31st)
Sampling Time Period 2 (August 1st to September 15th)
Sampling Time Period 3 (September 16th to October 31st)

The Universal Transverse Mercator (UTM) coordinates are a global grid system similar to latitude and longitude. Rather than using hemispheres, UTM coordinates divide the earth into 60 north-south zones of 6 degrees longitude each. The UTM coordinates are the distance in meters from the central meridian (Easting) and from the Earth's equator (Northing) for each of these 6 degree zones. A zone's central meridian is the line of longitude from the 6 degree intersection with the equator to the North Pole. The UTM coordinates for all river pools are based from zone 15. Please enter a UTM range for the pool(s) selected.

Another method of locating where the data were collected is by location code which is not as accurate as the UTM coordinates. The primary format for river mile is where r designates the river (M = Mississippi and I = Illinois), mmm.m is the river mile (recorded to the nearest 0.1 mile), and a is an alphabetic code for the relative lateral position across the floodplain (going west to east). The default is "All Location Codes."
