Reproductive readiness and behavioral ecology of wild hatchery-reared pallid sturgeon in the Missouri River above Fort Peck Reservoir, Montana


January 2014 - June 2017


Determine the age at sexual differentiation, age at first maturity, and spawning periodicity of wild hatchery-reared pallid sturgeon in the Missouri River. In addition, this project will replicate the research conducted by Gerrity et al. (2006, 2008) to determine if temporal changes have occurred in home range size and habitat use within the 1997 year class of pallid sturgeon. That is, has the 1997 year class become sexually mature and do they have similar home range size and habitat use as Gerrity et al. (2008) observed in 2003 (age 6) and 2004 (age 7)?
