Usually commercial exploitation becomes unviable before actual extinction occurs, although some species have been hunted to death for sport. You’d typically see this being a bigger problem for highly valued species like tuna where consumers are willing to pay premium prices for the remaining creatures, rather than more commodity species. The bigger risk extinction wise isn’t that we’ll fish a species to death, it’s that we’ll leave it in such a rough state that any number of random events might finish the species off.
