The Fish and Wildlife Service (FWS) will spend $175,000 for a study on the “swimming abilities” of fish in the Northern Rockies, the agency announced on Thursday.
The FWS, a bureau within the Department of the Interior, will award a grant for the study that will produce a “fish swimming video.”
The grant announcement, entitled “Cooperative Research Program on the Swimming Abilities of Native Stream Fishes in the Northern Rockies-Upper Great Plains Regions of Montana,” estimated the project’s cost at $175,000.
