Abstract

A method of taking up dead fishes from a net cage (1) comprises a pulling up of the net bottom into close proximity to the water level (11) while forming a bag, in which the dead fishes are collected in order subsequently to be taken up. In order to ensure that this taking up procedure can be carried out relatively quickly and with the least possible disturbance of the living fishes, this procedure is carried out by pulling up the bottom (13) of the net cage towards the water level in a wavy movement in the longitudinal direction of the net cage and preferably beginning from one side (26) of the net cage. Subsequently, the wavy movement is stopped a short distance from the opposite side (36) of the net cage, the bottom (13) of the net cage in this position being kept raised along the entire side (36) in question of the net cage, which results in a bag between the raised area of the net cage and the second side (36) of said net cage. The depth of this bag is subsequently reduced by pulling up the bottom of the net cage at the second side (36) of the net cage. A net cage for carrying out theabove method comprises hoisting means (27, 42, 48) positioned in sets along transverse lines interspaced in the longitudinal direction of the net cage. The said movement of the bottom (13) of the net cage is established by activating the above hoisting means in sequence.
