Abstract: Protective device for animal breeding, such as the breeding of fish, mussels or mollusks, includes at least an inner cage that can be positioned in a body of water and which is formed from a net. This inner cage is dimensioned with a mesh width such that the animals to be bred are retained within the net. It is preferably totally surrounded by at least one outer cage spaced apart from the inner cage, and which is produced from a net made of thin wires and/or strands. The mesh width of the outer cage is greater than the mesh width of the inner cage, and it is thus guaranteed that predators cannot damage the net of the inner cage from the outside.

This cage is dimensioned here with a mesh width such that the animals to be bred are retained within the net. It is preferably totally surrounded by at least one outer cage spaced apart from the latter and which is produced from a net made of thin wires and/or strands. The mesh width of the outer cage is greater than that of the inner cage, and it is thus guaranteed that predators cannot damage the net of the inner cage from the outside.
