Abstract: A system for indoor shrimp aquaculture is described that comprises a plurality of stacked raceways, each raceway being a long, flat rectangular tank comprising at least two sections arranged in series and scaled to accommodate shrimp of increasing size. The sections are separated by a moveable section divider whereby shrimp may be transferred between sections once they reach a predetermined size by opening the moveable section divider and allowing the shrimp and water to flow through into the next section. Each raceway includes a waste collection assembly situated at the downstream end of each section for collecting waste for removal. Methods of using the system to grow shrimp are also provided. The raceways are further adapted to facilitate operation of the production module at large scales, in this way; the system is scaleable to achieve high-throughput production of shrimp.

Abstract: A transportable device for colonizing and harvesting invertebrate animals in proximity to a floor of a body of water includes at least two quadrangular frames, each of which include a trapping surface. A central hinge is disposed between opposing, inner traverse sides of the at least two quadrangular frames and has a first one-way folding direction. Two secondary hinges are disposed on opposite sides of the central hinge, each of the secondary hinges having a second one-way folding direction that is opposite to the first one-way folding direction such that the at least two quadrangular frames have an opening angle with respect to each other that is adaptable to a structure of the floor of the body of water.

Abstract: The present invention relates to a device for raising, transporting and releasing on a sea bed (50) crustacea juveniles which are in a housing section (1), the housing section (1) being adapted for connection to an emigration device (60, 80, 100) and the emigration device (60, 80, 100) being provided with at least one bore (70, 86) arranged to form an open path between an area near the surface of the sea bed (50) and a tubular element (10) disposed in a cut-out (12) in the housing section (1).

Abstract: A floating habitat designed to be renewably buoyant, self-sustaining and optionally specialized for waterfowl nesting. The first embodiment comprises one or more flotation units, a source of compressed air, and a means for connecting the source of compressed air to the flotation units. Each flotation unit comprises an individual supply hose, an inflatable bladder, a relief valve, a diffusing manifold, bottom mesh, top mesh, and buoyant growth medium. An alternative embodiment comprises a self-compensating buoyancy system. In the waterfowl nesting embodiment, the floating habitat includes one or more waterfowl nesting structures and construction material selected to optimize the nesting habitat. The floating habitat can be comprised of scrap pieces or layers of polyester mesh material. The floating habitats can be combined to provide safe habitat for juvenile waterfowl, encourage colony nesting, or allow a variety of waterfowl or shore bird species to enjoy suitable habitat on the same floating habitat.

Abstract: An agitator is provided including an open system having a base holding a plurality of culturing beakers as well as a lid holding a tube transporting fresh seawater into each beaker, gently stirring the water within and eliminating any decaying embryos. Each beaker has at least a bottom made of mesh allowing water to flow through. The agitator can be used to culture any fragile planktonic organisms that require an extended rearing time.
