Not familar with the White Perch. Try to find out what they naturally eat at this time of the year and then match the hatch. That is about the only advice I can give to you. Early spring there won't be very many small fry as the spawn has not happened yet unless you are fishing down south.
I would imagine that it's feeding trough time for big fish when other speices fly leave the nest. Then small baits that mimic the small newly hatch fry may work if the fish are targeting them. If not then there are always bottom dwelling insects that they may be feeding on. There are small red worms that inhabit the bottom of most lakes that are fed upon by panfish.
I am not sure how particular White Perch are when it comes to feeding.
