Alec Lackmann et al. used thin-sectioned otoliths and bomb radiocarbon dating on earstones from the Bigmouth Buffalo fish. They found individuals can reach up to 112 years of age, and that many populations are largely comprised of individuals over 80 years, suggesting long-term recruitment failure due to dam construction in the 1930s.
