A method of dynamically reconfiguring sensor system operating parameter by receiving, at an electronic device, data indicative of one or more underwater object parameters corresponding to one or more underwater objects within a marine enclosure. A set of intrinsic operating parameters for a sensor system at a position within the marine enclosure is determined based at least in part on the data indicative of one or more underwater object parameters. The sensor system is configured according to the determined set of intrinsic operating parameters by changing at least one intrinsic operating parameter of the sensor system in response to the data indicative of one or more underwater object parameters.

An offshore wind-solar-aquaculture integrated floater is provided, including vertical-axis wind turbine systems, solar photovoltaic panels, and a cube aquaculture cage. Four vertical-axis wind turbine systems are respectively rigidly connected to four corners of the cage; solar photovoltaic panels and a living and working quarter are located on cage deck; and side frames of the cage are equipped with tensile nets, the bottom frame of cage is equipped with a bottom net, and columns of the cage are equipped with lifting rails. This floater has good stability, sea-keeping performance and high strength. Utilizations of offshore wind and solar energy above the cage are high and they complement each other in power generation. This disclosure manages to exploit ocean resources to an unprecedentedly large extent, while resolving the issue of combing power generation with marine aquaculture in moderate and deep seas.

A system for the elimination of parasites adhered to fish. The system includes an entry and drainage area configured for the fish with parasites to enter the system, the entry and drainage area joined to an application area through which the fish with parasites pass and come into contact with curtain electrodes and/or grill electrodes. The system includes spray nozzles at least partially housed in the application area and a return chute at least partially situated below the application area to receive and channel the sprayed water. The system also includes a pump that pumps the water to the spray nozzles and an outlet through which the fish without parasites exit the system.

There is provided an illumination system (100) for cultivation of aquatic animals. The illumination system (100) comprises at least one light source (110) emitting light, at least one light driver (120) arranged to drive the at least one light source (110), at least one light sensor (130) providing illuminance data for at least one point of interest (50) in said illumination system (100), and a controller (140). The controller (140) is adapted to provide control signals to the at least one light driver (120) driving the at least one light source (110) to emit light of a desired illuminance at the at least one point of interest (50). An ambient light sensor may be applied to determine control signals also in accordance with ambient light data.

An outlet basin for a fish pen is provided with at least one outlet hose extending from the outlet basin to a surface. The outlet basin includes a cylinder-shaped housing which is provided, at its upper portion, with a mounting collar arranged to be attached to a bottom portion of the fish pen, and which is provided, at its lower portion, with a through opening. The outlet basin further includes a cylinder-shaped outlet channel which, in a portion, is housed in the housing, the outlet channel is provided, at its upper portion, with a strainer covering the cross section of the outlet channel, an elongated annular space between the housing and the outlet channel, a slanted grating covering the entire annular space, the lowermost portion of the slanted grating being positioned just below the opening of the housing, a slanted bottom plate sealingly covering the entire annular space, and a lower through opening at the lowermost portion of the bottom plate.

Device, system and method for distribution of pesticides to reduce or eliminate parasitic creatures liable to infest aquaculture facilities or the animals kept in these, such as salmon lice in a fish farm. The invention is based on the use of pesticides at a concentration level low enough to not represent a dangerous level for the environment, but for a longer exposure period, sufficient to enable delousing to occur.

A floatable frame structure has concatenated frame modules, each formed of columns arranged substantially vertically. Neighboring columns are interconnected by upper and lower tie bars and form module sections. The connections between the tie bars and columns have rotary joints arranged at upper and lower nodes on the columns. At least one horizontal rotation joint is arranged for each column in the connection to an associated tie bar, and at least one spherical rotary joint or elastic rotary joint is arranged for each tie bar. Each module section is provided with elastic tensile elements secured to diagonally opposite upper and lower nodes, nodes lying diagonally opposite each other in the same horizontal plane and in the same frame module being connected by elastic tensile elements. Some columns form containers with submersible portions with positive buoyancy, and adjacent frame modules sharing at least one column.
