Those 5"-6" YP were one year old fish. Good amount of food can easily result 7"-10" YP by year's end after a March stocking. Smaller one of this group will be mostly males and ones larger than 7.5" are mostly females and carrying eggs this spring these these perch will appear very plump. Relative weight for these perch in early spring (prespawn) will be biased due to egg carrying fish. Catch a few of them in mid March and see what is present for plumpness.
Got out to feed tonight with the warm weather and the YP were very active. Will have to get a few on a hook and line soon to see how plump they are.
