The Effect of Black Bullhead Catfish and Bluegill Removals on the Fish Population of a Small Lake

The effect of removing various amounts of bluegill and black bullhead catfish from a small lake on the remaining fishes were studied. Estimates of population size by mark and recapture, numbers of desirable size fish, condition indexes and age and growth rates reveal some improvement in certain species but it was concluded that removals alone may not always produce greatly improved fish populations.
