It will be very informative to have a few interested in YP to actually measure the bottom temperatures where YP begin spawning. I have never done that. I always assumed slightly warmer temperatures were sensed by the YP and this stimulated or indicated the best place to be laying the eggs. YP always first start laying eggs in my south-east bank that receives afternoon sun. Common sense tells me that area has the warmest bottom water as heat build up is released from the shallow water bottom shoreline area. Dark bottoms can absorb lots of radiant energy from sunshine.
