Aspects of the present disclosure involve hydraulic systems and methods for altering a flow of a body of water, such as a river, channel, and/or other flowing or uncontained bodies of water. In one aspect, a hydraulic system provides a velocity barrier for the impedance of aquatic organism migration. More particularly, the velocity barrier may be adapted based on the swimming capabilities of one or more aquatic organisms to impede migration. The aquatic organism may be one or more species of fish, such as species sea lamprey (Petromyzon marinus). The example implementations shown and described herein reference the restriction of the sea lamprey. However, it will be appreciated that other aquatic organisms could be restricted by the presently disclosed technology, for example, with different hydraulic targets depending on swimming capabilities.

The present invention relates to an indoor aquaponics assembly which includes a base, an aquarium positioned above and supported by the base, a planter positioned above the aquarium, an aquarium conduit and a planter conduit. The planter is provided with at least two through holes facing towards the aquarium, one being adapted for a water drainage tube to pass through for draining water from the planter to the aquarium, and one being adapted for a tube of a pump to pass through for pumping water from the aquarium to the planter. The present invention aims at reducing the time and efforts required for caring and maintaining the aquarium and the plants.

Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

An energy efficient aquaculture system combining mixed-cell and raceway configurations. The system comprises a raceway tank, a raceway channel, a first water purification subsystem, and a second water purification subsystem. The system may include one or more of a hatching subsystem, a nursery subsystem, a feeding subsystem, a finishing subsystem, and a fish pumping system for transfer of fish between raceway tanks. A method of growing fish for commercial production using the aquaculture system is also provided.

Modular habitat structure (MHS) which accommodates one or more live inhabitants is comprised of a rigid pillar which extends linearly away from a base end toward an upper end. A plurality of major system components disposed at different locations along a length of the rigid pillar are each comprised of modular segments. A control unit controls a plurality of electronic devices integrated in the MHS, including one or more video cameras which generate live video streams of a wildlife habitat within the MHS, and communicates the video streams from the MHS to a remote computing device.

A lighting assembly includes a light guide having opposite first and second major surfaces and at least one edge surface extending between the first and second major surfaces, a solid-state light source arranged to emit light into the edge surface of the light guide, and a plurality of integrated optical elements associated with the first major surface to redirect the light emitted by the solid-state light source. The lighting assembly may further include an air circulation device and a heat transfer system configured to transfer heat generated by the solid-state lighting source to a flow of air generated by the air circulation device. The solid-state light source may include light-emitting diodes, laser diodes, and/or organic light emitting diodes configured to produce multiple colors. Also provided is a habitat including the lighting assembly, and related methods.

An example aquatic imaging system comprises a light source, a first platform coupled with a image capture device and a second platform that is parallel to the platform, the image capture device having a first field of view, and, the second platform being coupled to a organism tank, first organism tank having an inner wall, outer wall and a base that defines a well capable of retaining water, the base being parallel to the second platform, the organism tank configured to receive a light beam originating from the light source and configured to project at least a portion of the light beam through the well and in a directional plane that is parallel to the base, the image capture device configured to direct the first field of view from the first platform through the well in the organism tank.

The present disclosure relates to emersed shellfish storage. A container support has a surface to support containers. Each container has respective cells to accommodate live shellfish, such as lobster, in a vertical orientation substantially perpendicular to the surface. Water from a reservoir is pumped, intermittently in some embodiments, to one or more of the containers above the shellfish, and a collector collects and provides to the reservoir the water that is pumped by the pump system and flows over the shellfish. In an embodiment, the cells are provided by a divider that divides an interior space of each container, and the divider carries a perforated top insert at or below a top edge of each container, to distribute fluids to the cells.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling. The transfer assembly may also connect a holding facility, which may be dimensioned and structured to transfer mature marine life, possibly on an on-demand basis, to the harvesting facility.
