Biological data (length, weight, and age) for Slimy Sculpin (Cottus cognatus) sampled from Lake S-6 of the Arctic Long Term Ecological Research location.
A data frame of 117 observations on the following 3 variables:
Weight (nearest 0.1 g) at capture
Total length (nearest mm) at capture
Age (completed growing seasons from otoliths) at capture
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.
