Thanks for the links ewest, But the second one gets off the topic from spawning areas to repeat spawning in a season?? And it kinda seemed like the first link didnt have much helpful information it kinda jumped around. Anyone got direct expierence with this type a stuff.? I really have no need to know genetics of paternity analysis, although interesting not really what im looking for, im just a dumb fisherman that wants to catch more fish so i want to grow more lol.. What i got from all the reading is dont waste my time with making a bedding area maybe just a shovel of pea gravel in already existing beds?
