A system and method for managing and tracking fishing/hunting rules and regulations is provided. The system generally comprises a global positioning system (GPS), a processor operably connected to the GPS, a power supply, a display operably connected to the processor, and a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. The system and method are designed to easily and conveniently compile and store information or data related to wildlife sports. The system may use this information to help a user comply with state and federal rules and regulations via the creation of registration strategies and via indicia.

In one embodiment, an algae cultivation system includes a basin that contains a liquid and a photobioreactor at least partially immersed in the liquid of the basin, the photobioreactor comprising a closed container including multiple panels that together define an interior space in which algae can be cultivated, at least one of the panels being transparent, the photobioreactor further comprising an inflatable float associated with the container that can be filled with a gas to change one or both of the position and orientation of the container within the liquid.

Methods, systems, and computer-readable media that implement a mobile filtration system that provides sustainable, on-demand water filtration while supporting the growth and maintenance of organisms. The method includes determining an environmental parameter associated with a volume of water, determining, based on the determined environmental parameter, a control parameter for an autonomous submersible structure that includes a platform on which marine life grows, and generating, based on determining the control parameter, an instruction for the autonomous submersible structure.

The present invention discloses a kelp harvester. The kelp harvester includes a ship body and a U-shaped tripping piece, where two working chain racks are symmetrically arranged on both sides of the ship body; each working chain rack is provided with a chain and a chain driving device used to drive the chain to operate; multiple rope clamping devices are fixedly arranged on each chain; the rope clamping devices can clamp main ropes, so that when the chains operate, the rope clamping devices can drive the ship body to move along with the operation of the chains; the U-shaped tripping piece is rotatablely connected to the ship body through a hinge; and the ship body is further fixedly provided with a limiting baffle, and the limiting baffle limits the U-shaped tripping piece to stopping rotation when the U-shaped tripping piece is in a vertical state.

A module for retrofitting a boat for collection of floating biomass has a telescoping beam that spans the width of the boat and connects to aft-ends of levers that rest on the gunwales. The telescoping beam extends beyond both gunwales such that outboard net holders can be disposed thereon. Nets are attached to and held open by the net holders. The nets are at least partially submerged and fill with sargassum as the boat moves forward. Longitudinal drag forces are resisted by chains that connect the levers to the bow. Torsion around the telescoping beam is resisted by pretensioned straps that pass under the boat and over the aft-ends of the levers, which extend towards the bow to minimize strap tension and reaction force against gunwales. Horizontal moments in the outboard portions of the telescoping beam are absorbed by the inboard portion of the telescoping beam.

A floating seaweed and floating aquatic plant farming system includes an enclosed area positioned in a water body. The enclosed area is defined by one or more floating booms each including an attached mesh skirt. The system also includes a harvesting system for collecting seaweed growth in the floating enclosed area. The harvesting system is static or dynamic in relation to the floating enclosed area. The system may also include a processing system on a vessel containing the harvesting system. The one or more floating booms are secured in a location in the water body with an anchor system or with pilings. Alternatively, the enclosed area is defined by one or more mesh panels each secured to, and extending across spaces between, pilings. The seaweed is grown within the enclosed area and harvested by the harvesting system.

Floating ponds for the cultivation of algae are disclosed. The floating ponds consist of a buoyant framework, a liner, a culture, and a mooring system. Submersible floating ponds are disclosed with a buoyant framework built from tubes that may be filled or partially filled with, for example, air, or water, or the surrounding water, or the culture, and thereby the present invention provides a framework in which the buoyancy may be modulated. Use of submerging lines and spools are disclosed to control the orientation and depth of the floating pond during submersion.

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a condition of the algal cells and/or a condition of an algal cell culture provided by cultivating the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured condition of the algal cells and/or the measured condition of the algal cell culture.

A system and method for converting food waste and other biologically-derived waste materials into nutrients for an algal growth system using worms to produce such nutrients is described. In one embodiment, a method for converting food waste into nutrients for an algal growth system using worms includes providing food waste to a container including a plurality of worms. The method also includes collecting castings from the food waste processed by the plurality of worms. The method further includes providing a wash to the container. The wash causes the castings to move to a bottom portion of the container adjacent to a moveable screen. The method includes actuating the moveable screen so that the castings pass through a plurality of holes in the moveable screen. The method also includes providing the passed castings to an algal growth system.

An algae cultivation system may include: a plurality of panels within a cultivation container, positioned along a first axis perpendicular to the gravitational force, wherein a cultivation volume is created between each pair of panels, and wherein the cultivation volumes are fluidly coupled so as to allow horizontal flow therebetween along the first axis; at least one first sparger, to distribute a first fluid into the container at a first operating flow rate; at least one second sparger, to distribute a second fluid into the container at a second operating flow rate; and at least one controller, to control the first operating flow rate and the second operating flow rate. The first operating flow rate may be adapted to allow turbulent mixing the algae in the cultivation container, and the second operating flow rate may be adapted to allow assimilation of materials in a liquid in the cultivation container.
