No, that's been the case pretty much since they started keeping records. Our federation started tracking fish records back in the fifties and it seems the primary focus of all angling was those three species.
The introduction of different trout species has certainly given opportunities to other anglers to look at those other species in a lot of areas that normally may not have experienced anything outside of those three main species.
Largemouth bass and smallmouth bass have been introduced in Saskatchewan in the last 15 years, and there are a couple of other fisheries that are doing very well.
