Bill - That is a very enlightening response. How the heck do they find each other, pheromones?
Follow up question - If a single breeding pair of BG did manage to spawn in a pond with a mature, balanced population of forage fish and top predators (and the adult BG were then eaten after guarding the nest), would the BG progeny suffer 100% mortality through predation or would some of the BG survive to spawning age?
