Abstract
A depresser designed to keep a fish, towed by a ship, submerged comprises a flat swept wing joined to the towing cable by means of three suspenders making it possible to set it at an optimal angle of incidence. This enables a fish to be towed at a high speed which may go up to 30 knots while, at the same time, keeping it at a substantially constant depth of submersion.
