An apparatus for containing, maintaining and raising oysters, mollusks and other aquatic life, the apparatus being formed of wood of sufficient buoyancy so that the structure will float on or in the surface of a body of water without additional buoyant elements. The apparatus has opening on each of two opposite sides and slats covering the top and the bottom of the box, the size of the holes and the spacing between the slats having dimensions such that the nutrient containing water body within which the structure has been deployed, may freely flow through the box while containing and maintaining the selected aquatic life within the apparatus. The device may also contain baffles within the interior space to keep the containing and growing aquatic life form shifting in the device as nutrient rich water passes therethrough.

This disclosure relates to methods and systems for repelling one or more fish eating predators (4) from a fish-containing area (6) within a sea, fjord, river or lake, wherein a moving image of a predator (18) of the one or more fish eating predators (4) is provided at and/or near a boundary of the fish-containing area (6).

Various aspects comprise controlling and/or euthanizing vermin or pests for preventing such vermin or pests from entering into a geographical area or into a building, wherein the device comprises at least one completely or partially uninsulated electrically conducting wire or conductor connected to an electrical current source, providing controlled electrical pulses to said conductor or wire in the form of pulses or pulse trains. The device may be used in a method for controlling the access of pests/vermin to a geographical location, building or property wherein the electrically conducting wire(s) lead(s) an electrical current with an amperage of not less than 0.0001 A. The device and method may be particularly suited for removing/controlling pests/vermin on land.
