Massachusetts Cooperative Fish and Wildlife Research Unit
The Cooperative Research Unit Program (CRUP) began in the 1930s. For much of its history the CRUP was part of the U. S. Fish and Wildlife Service until the 1990s, when CRUP joined the U. S. Geological Survey. The Massachusetts Cooperative Wildlife Research Unit was one of the early Units, established in 1948. In 1963, the Fish Unit was formed, and in 1990 the two were combined into the Massachusetts Cooperative Fish and Wildlife Research Unit. There are currently about 40 Units across the country.
