This is the 1998 status assessment of the scaleshell mussel in the United States. It includes biological information on the species, distribution status information and detailed status figures.
A nutria is given a shot to put it to sleep while the collar is measured. Tagging the animals will help biologists to better understand the nutria as well as prevent their spreading.
The U.S. Fish and Wildlife Service does studies to find out how these animals affect habitat and other species. Biologists adjust the collar on this nutria prior to releasing him.
A sheet covers the caged nutria to keep it calm during the tail tagging. Tagging the animals will help biologists to better understand the nutria and prevent their spreading.
A collar tag to be put on a nutria. It's designed stretch so it can be put on snugly and a nutria will neither get a limb stuck inside nor have trouble breathing. Tagging the animals will help biologists to better understand the nutria's habits and...
The tagged nutria is released back into the water. Tagging the animals will help biologists to better understand the habits of nutria and prevent their spreading.
A collar is successfully attached to the nutria. Tagging the animals will help biologists to better understand the nutria and to prevent their spreading.
