Abstract
A semi-submersible fish feeder (1) for use in fish farms and aquariums which provides a feeding chamber (3) that floats below the surface of water and thereby enables edible materials such as food or medicine to be more controllably and evenly distributed to fish. A buoyancy aid (2) and ballast chamber (7) allow the depth of the feeding chamber within the water to be controlled. The feeding chamber is typically a volume of edible material enclosed by a net (10) through which fish can eat.
