The invention relates to fish farming, the cages for commercial breeding of fish, and is aimed at improving the living conditions of fish and their maintenance.A technical purpose, a utility model is to expand the possibilities of biotechnology cage device, with the simultaneous creation of an enabling environment, both the content of the fish, and the possibility of experts of various manipulations with it. For this circuit the netting of the cage chamber are made of stainless Chain web and adherent to the contour of the bottom of large diameter as a rigid plane.The design of the netting of the cage chamber, bottom in the raised position provides comfortable conditions for farmed fish and the staff at the time of observation, control and other manipulations with fish.Mobility (folding, unfolding, lifting, lowering) Chain webs provide the ring diameter at least 57 mm, and further to 127 mm of the wire diameter more than 2.5 mm, which are not fixed to each other in a rigid coupling. Connect ring stainless wire without soldering solder argon, an argon brazing solder, laser welding contact. Method ring compound is selected depending on its size, the thickness of the wire, the strength characteristics of the web assembly, and the availability of appropriate equipment. Bottom - the podium facilitate the pontoons of welded pipes PDN that drive and fixed to the reinforcement cage bottom and underneath, lifting by a manual winch.Полезная модель относится к рыбоводству, к садкам для товарного выращивания рыб, и направлена на улучшение условий содержания рыбы и их обслуживания.Технической целью разработанной полезной модели является расширение биотехнологических возможностей садкового устройства, с одновременным созданием благоприятных условий, как содержания рыб, так и возможности проведения специалистами различных манипуляций с ней. Для этого контур сетной камеры садка выполняют из нержавеющего кольчужного полотна, а плотно прилегающее к контуру днище как жесткую плоскость
