Nice setup.
We usually bring ours inside at an inch or so, and start them on a combo of mash/#1 from the same belt feeders, depending on the size. we try to leave them out in the ponds as long as possible/food holds out. Sometimes add a little krill meal,or hand broken freeze dried krill, again depending on the fishes' size,as we do with the LMB, but don't bother to moisten it like with the bass.

The YP take to it MUCH faster than any other species we fool with. They will ball up under the feeders, literally to the point where you'll squash them when cleaning the tanks!

Never tried the light thing. YP are one of my favoritwe fish, bot hin general, and in terms of culturing them.Keep us posted.Thanks
