Shelby FF only sold feed trained WE one year 2022.

The V or Y body bars on the YP I think are just a variation of body markings. IMO those individuals grow slightly better than the other YP but that is just my opinion - no proof. YP from Shelby and Mill Creek are the same genetic parentage as long time domesticated YP that feed train easily.

WE and apparently feed trained WE struggle to grow well with high relative weight in pond habitats. Snipe our PB member saugeye ( SAE = Saugeye is a hybrid of WE X sauger SGR) expert says the saugeye as a hybrid in ponds and lakes grow much better with good RW compared to WE in smaller waters. SAE snipe says from extensive experience,, SAE thrive well on a diet of sunfish species including small crappie. The biggest problem is saugeye are very rare at private fish farms and are raised almost exclusively by State DNR fish hatcheries. Snipe is able to privately grow a few thousand saugeye fingerlings each year.

FYI - once a fish fry develops its full complement of fins it is technically now called a fingerling.
