The Division of Fishes at the Museum of Southwestern Biology

The  Museum of Southwestern Biology (MSB) Division of Fishes is a resource for research, training, and education. It is a primary repository for specimens and data collected by academic and agency biologists for research in fish ecology, aquatic biology and conservation. The Division serves the scientific and conservation community worldwide through online access to georeferenced localities and other archival materials.

The MSB Fish Collection is the largest of its type in the southwestern US and comprises more than 100,000 lots of more than 4.5 million specimens. Research in the collection focuses on long-term population studies, early life history, community ecology, reproductive biology, and genomics. The collection provides an exceptionally well-documented record of the profound changes to biodiversity that have occurred in the desert southwest over the last century.
