A method and device for collecting animals living on or in a water bottom such as crustaceans and shellfish and fish, wherein a collecting device (5) is moved over the bottom, which collecting device is provided with a device for moving the animals from or off the water bottom, in particular at least one tine (14) that can penetrate into the bottom and with which said animals can be taken or forced from or off the bottom, while said at least one tine is provided with a fluid outlet through which under pressure, a fluid, in particular water, is forced into the bottom, such that a top layer of the bottom is stirred up and animals living therein or thereon are dislodged, which animals are captured in the collecting device.

L'invention concerne un procédé et un dispositif destinés à collecter des animaux vivant sur ou dans un fond marin, et notamment des crustacés, des mollusques et des poissons. Un dispositif collecteur (5) est déplacé sur le fond marin, ce dispositif comportant un élément permettant de déplacer les animaux à partir du fond marin, et notamment au moins un peigne (14) pouvant pénétrer dans ce fond et permettant de piéger ou d'extraire les animaux dudit fond. Ce peigne comprend un organe de sortie de liquide (17) par l'intermédiaire duquel un liquide sous pression, et notamment de l'eau, est injecté dans le fond de sorte que la couche supérieure de ce fond soit remuée et que les animaux vivant dans ou sur celle-ci soient délogés, lesdits animaux étant alors capturés dans le dispositif collecteur. Chaque peigne peut se déplacer sur la base de signaux produits par une unité de détection (21) servant à détecter les animaux. De préférence, l'unité de détection est placée à l'avant des peignes.
