Notes On Euphausiids

Abstract

(a) Vertical MigrationThe material for this paper was obtained in two voyages on the Milford steam trawler Macaw, and I owe all thanks to Capt: Rumble, and to the crew, not only for much practical help, but for a pleasant time. Capt. Rumble's knowledge of the area worked, based on 30 years' experience, can only be compared with a farmer's knowledge of his own acres, and he has been responsible for determining the position of each haul.
