Abstract: Food dispensing apparatus minimizes the likelihood that food particles dispensed into an aquarium will contaminate the water filtration system or will stick to the sides of the aquarium. The food dispensing system suspends a hollow food dispensing member in water in the aquarium such that the food dispensing member guides food to the bottom of the aquarium free from being transported by prevailing currents in the aquarium.

Abstract: A method is provided for producing prey organisms such as Artermia and rotifers, for feeding aquacultural organisms in particular at the larval stage. The method comprises cultivating the prey organisms during at least part of their life cycle in an aqueous medium comprising at least one lipid component having a DHA content of at least 30 wt %. The enriched prey organisms preferably have a DHA content of at least 12 wt % of their total lipid content. The prey organisms are suitable feed for larvae of fish including halibut, turbot, bass, and flounder, and crustaceans and molluscs.

Abstract: A fish feeder having an inner tray sliding within an outer tray. The trays are provided with holes which, when brought into alignment, allow feed to drop from the inner tray through the outer tray and on to a spreader, whereby the food is evenly distributed across the surface of water. The inner tray is driven by pneumatic actuation to reduce noise and precisely control the amount of feed dropped upon each actuation. Means are provided for reducing the ingress of food particulate between the trays, which would otherwise act to increase friction and decrease the efficiency and repeatability associated with food delivery.

Abstract: A feeding apparatus and particularly a feeding apparatus capable of feeding pet fish or pets randomly or at a selected time interval. It includes a case and a control dock housed in the case. A first control button and a second control button are provided to selectively activate the motor on the control dock to operate at a selected time interval or randomly, thereby a feed box is driven to rotate synchronously.

Abstract: An interactive aquatic animal feeding method and device includes an elongated lead secured to a body with non-living edible material. The body can have characteristics to aid in the attraction of a feeding response from the aquatic animal, such as movement, shape, scent, coloring, flavoring, and texture. Movement may be facilitated by use of a flexible, resilient and/or elastic elongated lead. The body can be manipulated and moved in an aquarium. One or more devices can be packaged in a shell with a plurality of cavities to receive the bodies, and slits formed in walls surrounding the cavities to receive and bind the elongated leads. A series of channels adjacent to the walls or a single channel formed around the wall can be used to secure and store excess length of the elongated leads.

Abstract: Particles (10) for controlling, treating, feeding of aquatic invertebrate filter feeding organisms such as mussels, clams, oysters and insect larvae comprising a biologically active ingredient (13) embedded within or surrounded by an innocuous carrier material (12). The organism effectively concentrates the active ingredient within its body by feeding on the particles, thereby reducing the total amount of active ingredient required to be used.

Abstract: An automatic food dispenser for animals, fish or the like, comprising of a housing, controls, and with a hopper within, for containing food, the base of said hopper having an opening for the food to exit (feed exit), said opening being in close proximity to a dispensing mechanism, said mechanism having a surface, thus creating a sufficient seal to prevent the undesired escape of food from said hopper, said dispensing mechanism having an aperture on it's surface, whereupon, with the rotation of the dispensing mechanism about it's axis, and the subsequent alignment of the aperture with opening at the base of the of the hopper, feed may escape from the hopper through said aperture, and hence directly through the open base of the dispensing mechanism, the volume of feed dispensed being a function of the variable speed of rotation, and the number of “to and fro” motions of the dispensing mechanism past the feed exit.

Abstract: In a feeder for dispensing moist feed pellets to fish in a fish farm, there are provided a feed storage hopper, a screen group for separating fish feed into edible-size pellets and feed waste, and a conveyor for conveying the feed material from the hopper to the screen group. The feed waste is collected in a receptacle for later recycling through a feed pellet extruder. The feeder also has an air delivery system comprising a venturi eductor and a nozzle for aspiring the edible-size pellets from the screen group and for delivering the pellets into an air stream directed toward a fish pen. Most importantly, the conveyor is a belt type conveyor with spaced-apart flights, providing this feeder with the ability to dispense discrete amounts of fish feed in an intermittent feed mode from the hopper, through the screen group and into the air delivery system.

Abstract: Bait for attracting crustaceans and non-crustaceans which are caught in trap fishery. The bait includes a pelletized carrier composed of ingredients intended for long life in sea water. The pelletized carrier is mixed with specific attractants depending on the desired catch and a fish oil is added to coat the pellets and attractant and to allow for the timed release of the attractant. In experiments to date, it has been found that the use of the pelletized carrier and attractant together with the fish oil coating has been effective as a bait in attracting catch and has an extended life within the traps.

Abstract: A convenient Lid (FIGS. 1, 2 and 3) specifically designed to fit on the standard clear plastic cup (FIG. 4) available especially for tropical fish market present. To prevent the problem of water spill and sufficient air breathing for the Betta fish, this Lid is incorporate a cylindrical cone in the center and is pointed inward the cup, conditionally the water level must always fill half inch below the tip of the cylindrical cone. When the plastic cup fills with water with the Lid on-as a unit, this unit can be tip or roll any which way, and yet the water still remains inside the cup and air passage is still available. Furthermore, with the Lid secure tight on the plastic cup, it is also an ideal to easily transport, store, display and feed the Betta fish. This invention can be used to store any type of tropical fish (which is not required compress air), marine fish, worm, insect and both live or dry fish food.

Abstract: To increase the occasions when fish or other aquatic animals enter an aquatic habitat extension device, a feed delivery system delivers feed through the entryway and releases it so that it floats up to an air pocket trapped in the upper portion of an aquatic habitat extension device. The delivery system employs a feeding mechanism that releases feed into the transparent habitat structure. The feeding mechanism is delivered to the habitat either through the use of a feeding pole or feeding platform.

Abstract: A fish feeding mechanism that disburses fish food within a fish tank in metered quantities, allowing fish the time to consume the food before it settles. The feeding mechanism is affixed to the inside of the fish tank by a suction cup or a suspension hook and comprises a food container whose top end is positioned above the water surface. The submerged surface end of the food container includes at least one food outlet that opens into the fish tank. Adjacent to the food container and also submerged inside the fish tank is a lift tube provided with an inlet port to allow water from the fish tank to enter, while a channel in the lift tube allows the water to enter the food container. An air line is inserted into the lift tube's inlet port and the compressed air therefrom flows from the mouth of the air line and enters the lift tube, causing air bubbles to rise to create an upward current of water.
