Abstract
A method and device for fishing up an immersed body from a position spaced from and disposed above the immersed body. A fishing member is moored to the body, with the member including a support integral with the body and a releasable portion. The support and the releasable portion are initially assembled together. The releasable portion is released, leading to the separation of the releasable portion and the support. Upon the releasable portion reaching the position, at the level of the position lift connecting members are moored to the fishing member, with the lift connecting members being attached to the body and to the releasable portion. This fishing member is actuated so as to place the body in a vicinity of the fishing member.
