Details

Slimy Sculpin were captured from Lake S-6 during the summers of 1988 and 1989. Sculpins were captured using canning jars with acetate funnels inserted in them (similar in design to some minnow traps). The sculpin traps were set by raft and placed on the bottom of the lake in a specific habitat (inshore, rocky, rock-mud interface, and mud bottom). (Roughly) every three days the traps were retrieved and the sculpins, if any, were removed. The ages of the fish were determined by counting the rings in their otoliths.
