Method for large-capacity containment of fish, or arrangement of an advantageous swim cage for the method

The method relates to large-capacity keeping of fish, in particular in still waters, in which at least one swim cage (1, 2, 3, 4, 5, 6) is laid in the water as a fish container, the fish are disinfected against parasites and placed in this cage in the growth ratio 120 kg/m , whereas fish which deviate in individual weight by 30% pass into at least one cage above 10 DEG C, or to a maximum of 0 DEG C cooling, depending on the fish species, a fish feeder (8) is accommodated in each of the cages, into which a fish food, corresponding to the fish species, with the composition of eggwhite, plant residues, vitamins is dosed, a water-stirring device (10) is furthermore installed in the vicinity of the cages, which is switched on at the commencement of freezing of the surface of the water (-4 DEG C to 0 DEG C), and in which the fish catch, measured against the fish stock, is kept in such a manner that the growth ratio roughly approximates the value of 120 kg/m .
