This study looked at the age of bigmouth buffalo in Minnesota and found they are the oldest living freshwater teleost fish! Their study found 5 individuals over 100 years old, with the oldest being 112!
The article is absolutely worth the read. It makes a great case that bigmouth buffalo need further protection (i.e. more than "none") since they are long lived fish with sporadic reproduction.
It is also a great example of how little we actually know about the ecosystems right in front of us! Come to find out the oldest freshwater teleost in the world (out of ~12,000 species) is living in Minnesota and no one even knew. The previous maximum age reported for bigmouth buffs was only 26!
We should all make an effort to pass this article on to regulatory agencies where we live. This is proof positive that bigmouth buffalo shouldn't be subjected to unrestricted harvest from nets or arrows.
