A dissolvable pellet (Fig. 1), biscuit or the like to supply a nutrient, a chemical substance, etc., to an aqueous environment. The pellet or biscuit comprises a primary ingredient, such as a nutrient or a chemical substance, and a gaseous substance, such as air or oxygen. The dissolvable pellet is supplied into an aqueous environment, wherein it dissolves to release the primary ingredient and air or oxygen. One embodiment may include fish food and oxygen, to feed fish and simultaneously replenish the oxygen levels in the water. A device to supply insects to aqueous animals is also disclosed, which incorporates an insect attraction means, such as a light source (Fig. 2) or a food source (Fig. 3). The light source may be a UV light to stun or kill the insects such that they drop to the water surface, or, a food source, such as meat or decaying matter, whereby insects, such as maggots are encouraged to breed. The device may be integrated with a naturally occuring environment, or, may be entirely fabricated and, optionally include the provision of means to control the environmental conditions. |
