When it comes to stocking fisheries, it’s vital to match the right fish with the right habitat. But that means more than merely matching trout to stream. Two populations of the same species can develop differences over thousands of years that suit them to one environment over another. And although breeding between strains is common, fishery managers still treasure those strains that have remained relatively pure throughout the centuries.
