Use of Rotenone in Restoring Balance to Overcrowded Fish Populations in Alabama Lakes

They resulted from a combination factors, including presence undesirable fish species, infestation with branched alga, kills, loss over the spillway, and heavy fishing.

The annual average catch anglers was 193.4 pounds per acre years that five lakes contained populations, 132.7 forage populations. Although these for varying periods time, an 156 fishermen caught 174.5 8 open continuous This high sustained harvest ...
