Abstract:
The invention is an apparatus unit that adjusts the dispersion from a compartment to an aqueous solution in response to an independent variable such as an environmental factor, in order to optimize seeding, marking, warning or treatment. The compartment enables any selection of solids, liquids or gasses to be contained and mixed when ready for dispersion. A preferred embodiment is a solar powered pump, self-contained within a buoy over a shallow tidal pool, for the purpose of distributing seeds for marine vegetation under ideal conditions for propagation. The unit provides for sensing and measurement of the environment, then adapting the dispersion for optimum effect.

Abstract:
A method of operating a variable speed pump in an aquaculture system including a culture tank that houses aquatic life. The method includes monitoring a dissolved oxygen level in the culture tank, determining a dissolved oxygen threshold based on current respiration requirements of the aquatic life in the culture tank, and comparing the dissolved oxygen level to the dissolved oxygen threshold. When the dissolved oxygen level is below the dissolved oxygen threshold, the method further includes increasing a speed of the variable speed pump until a flow rate through the culture tank that maintains the dissolved oxygen level at or above the dissolved oxygen threshold is reached. The method also includes updating the dissolved oxygen threshold based on new respiration requirements of the aquatic life as the aquatic life matures through its growth cycle.
Abstract:
An autonomous open-ocean fish-farming structure has a submersible cage enclosure tethered to a topside buoy. The topside buoy stores feed, is equipped with radio telemetry to communicate positioning signals transmitted from external sources, and generates electrical power using, for example, a hybrid solar OTEC heat engine. The structure is navigated and maintained in a geostationary position within the ocean environment by means of position-correction technology and is propelled by thrusters attached to the cage enclosure and, optionally, to the underside of the topside buoy. The self-positioning, self-powered fish-farming structure enables unmanned, extended marine deployment in deeper ocean waters without the need for tethering or anchoring to the ocean floor. Multiple structures can be maintained in a spaced apart configuration to comprise a flotilla of fish farming structures attended by a tender ship that is autonomous, easily serviced and conveniently relocated.
Abstract:
A closed recirculating aquaponics system combined with a biofloc tank for symbiotic breeding of aquatic species and plant species, wherein the culture water for growing aquatic species is transferred to a plant growing apparatus, organic material in the culture water is used as nutrients for plant species and the water is purified in the plant growing apparatus, and purified water is reused as culture water for aquatic species to facilitate symbiotic breeding of aquatic species and plant species without any need of culture water exchange, reducing cost for production and enhancing production efficiency.
Abstract:
A viscous fish egg killing device is provided. Every two conductive fish nests (1) are distributed side by side at a certain distance. One conductive fish nest (1) of every two conductive fish nests (1) is connected to a positive pole (3) of a power source, and the other conductive fish nest (1) is connected to a negative pole (5) of the power source. Each conductive fish nest (1) is connected in series or in parallel to the power source through a conducting wire (2). The fish nest attracts fish to lay eggs. After the device is electrified, an electric field is formed between two conductive fish nests, so as to kill fertilized eggs in the fish nest, and a method for eliminating invading fish is provided from the perspective of eliminating fertilized eggs of the fish in reverse thinking, and the device has a simple structure, is easy to be operated, and is efficient.
Abstract:
A lice treatment system for marine organisms, such as fish, is described where the system is a closed system comprising: an inlet (1) for fish that shall be treated, a first separator (2) to separate the fish and water and which is arranged after the inlet (1), a pipeline (6) for the transport of the fish, in which, at least, one part of the pipeline (6) constitutes a liquid bath (5) for the fish and which is arranged to receive the treatment liquid, a second separator (7) to separate the fish and the treatment liquid, an outlet (8) for the discharge of the treated fish and which is arranged after the second separator (7), and a circulation pump (10) for the circulation of the treatment liquid in the closed system. The part of the pipeline that constitutes the liquid bath (5) is formed in a U-shape so that a liquid bath with respective liquid surfaces (4) is formed.
