    • A seine device (111a, 111b, 111c) to be used submerged in a mass of water (2), in which a plurality of seine meshes are formed by one or more thread-shaped materials (112, 113, 114) being joined together, the seine (111a, 111b, 111c) including one or more signal reflection means (42, 43, 115) which are localized to at least one seine portion (11a, 11b, 11c) and are arranged for the reflection of an acoustic signal emitted from a sound source (31). A line to be used submerged in a mass of water (2), at least part of the line (4a, 4b) exhibiting signal-reflecting properties which are different from the signal-reflecting properties of other parts of the line (4a, 4b). A system for detecting a seine or a line submerged in a mass of water (2).
