Meeting Abstract 89.4  Thursday, Jan. 7  Effects of wall compliance on swimbladder function in zebrafish CROLL, R.P.*; STOYEK, M.R.; SMITH, F.M.; Dalhousie Univ; Dalhousie Univ; Dalhousie Univ roger.croll@dal.ca Zebrafish use gas-filled swimbladders to attain nearly neutral buoyancy, contribute to three-dimensional orientation (pitch and roll), and facilitate hearing (via the Weberian apparatus). However, swimbladder volume varies with depth-related […]
