The heat and the otters are my biggest concerns. The supplier thought I needed the FHM to keep the LMB off the HSB. But I think the otters got all the larger LMB. The few I've caught this year have been 10" or less, and I think he said the HSB would be 5 - 6". But the FHM won't hurt, as long as they're healthy and only FHM. The forecast is for 80 tomorrow - about the hotest day so far this year.
