Abstract: The swimbladder volumes of freshwater goldfish and marine rockfish are determined using a non-destructive method. The swimbladder of the gopher rockfish, Sebastes coranatus is found to occupy 6.0 % of the body volume, while the relative volume of the goldfish is determined at 8.1%. S. coronatus is found capable of short-term swimming compensation for excess bouyancy induced by a pressure reduction of 50 %. A survey of the habits, morphologies, and development of swimbladders is conducted for six rock-dwelling teleosts.
