The mechanical relationships between the clupeid swimbladder, inner ear and lateral line

INTRODUCTION In earlier papers (Allen, Blaxter & Denton, 1976; Blaxter & Denton, 1976) an account was given of the development and structure of the swimbladder-bulla-lateral line system of the herring Clupea harengus L. and sprat Clupea sprattus (L.) and its function in the larval stage. In this paper we describe experiments on juveniles of these species in which the system is fully developed.
