The Fish and Wildlife Research Institute has three extensive collections which include more than 600,000 cataloged, preserved invertebrates as well as adult and larval fish. Scientists use these collections as guides as they identify animals collected during research. Collections staff members also use specimens for presentations, coordinate loans to be used as teaching or research aids, and assist scientists and the public with identifying species.
SIS staff members maintain voucher, reference, educational, and research collections which contain cataloged lots of fish larvae, fish, and invertebrate specimens. The specimens are available for loan to researchers and educators worldwide.
