Federal Aid Research

Research funded by the Dingel-Johnson Act requires annual reports, known as Federal Aid reports. The table below links to the record for each project, with links to the digital copy and a call number for the print copy located in the CPW Research Library. 

Numbering systems changed throughout the years, the majority of the aquatics research project numbers begin with an F. Within each project there are often multiple jobs.

Example:
Westslope Warmwater Fisheries
Federal Aid Project F-325 (reports issued annually 1997-2007)
Within the F-325 project are various jobs; most of these have not been cataloged individually. For example Job 1: "Effectiveness of ISMP for Sampling Centrarchids in Riverine Habitats"; Job 2: "Fish Anti-Escapement Strategies/Devices for Ponds/Reservoirs" and so on. This particular project had five jobs.
