FIELD: fish farming.
SUBSTANCE: complex fish protection device contains one or more folding element: a visor or overlap and one or more folding element, for example, a side screen and/or its element and/or an electrode and/or its element and/or a water-retaining grid and/or its element and/or a water-permeable screen and/or its element and/or a flow generator and/or its element. In this case, bringing one or more folding elements of the fish protection device into operational mode is carried out under the influence of gravity and/or by using one or more load and/or float and/or mechanism and/or by performing one or more elements of the fish protection device from floating materials/floating. The folding design of one or more elements of the fish protection device makes it possible to significantly simplify the process of its descent/ascent, installation in the operational mode of operation and use, cleaning/maintenance, etc., while such a design makes it possible while it is descended/ascended, installed in the operational mode of operation and use, to take vertical, horizontal, inclined or any given position/configuration, does not require reconstruction of the GTS (overlap, grooves, guides under the retaining grilles and gates, the back wall, fencing, etc.) and carrying out expensive (underwater technical, etc.) work, during descent/ascent from the water has minimal resistance, reduces the likelihood of garbage collection, i.e. requires less effort to raise/descend compared to known inventions, does not require the use of divers, etc.
EFFECT: folding design of one or more elements of the fish protection device makes it possible to change the angle and/or mark of its installation, for example, in different seasons of the year of operation of the water intake, which makes it possible to change the zone from which water is taken, which can increase the effectiveness of fish protection during the operation of the fish protection device, because in different seasons of the year the water temperature, the size of the fish and the depth of fish habitat change.
