Oh, for Cod's Hake
Not more fish Puns!
Cod aren't typically considered classic anadromous fish like salmon or shad; they're primarily marine, but some related species, like the Atlantic tomcod, are "semi-anadromous," moving from saltwater to brackish/fresh estuaries to spawn, showing tolerance for both environments, which is a key trait of anadromous fish born in freshwater but living in saltwater to reproduce.
