| Although called a minnow, the topminnow is not really a minnow but belongs to the family Fundulidae. |
| Associations between MHC heterozygosity and infectious diseases in free-ranging animals under natural conditions have been found in Chinook salmon and in Gila topminnow. |
| The endangered Gila topminnow is a small guppy-like, live-bearing fish. |
| This study documents a new county record and the first time the golden topminnow has been reported from the Saline River. |
| For MHC sampling, degenerate PCR primers were designed from an alignment of guppy, topminnow, cichlid, and bass Mhc class II B sequences found in GenBank. |
| Since its listing in 1967, the Gila topminnow has been reintroduced into more habitat than any other native fish species in the Southwest. |
