I don't think anyone is saying carp are not fun to catch and are even worth as an intended quarry. What Spoondog and others have tried to explain that the observations, stories, vidoes, postulations, philosophies, observances and whatever else it is are all fine and good, however it is simply not a scientific study. One with parameters, protocols that are followed etc. in order to make the data useable. Sort of why the samples nets or electro shocking is always done in the same locations, so there is a basis for comparison to previous data. Lakes that are more nutritious are going to grow big fish faster than less nutrient rich fish, that means both Carp and LMB if all the other needs are met. Questions like what eats baby carp are valid questuins, likely every predator in the water will happily eat them if available. Might make good fodder for a doctoral study for a college student. Simply put the reasons for the studies not having been done before is that nobody cared, doesn't make it right just a fact. Using you carp to feed fish in a hatchery is a good idea, again good fodder for a graduate study.
