The invention provides a copper-zinc alloy with low lead content useful in the manufacture of wire used in the manufacture of cages for aquaculture, where said wire suffers the least deterioration due to loss of zinc during exposure to stagnant water, water of little movement or sea waters.

The present disclosure proposes an improved apparatus and method for counting of sea lice by providing a stable and controlled light environment which ensures counting of sea lice reliably and independent of weather conditions and an optimized spectral power distribution and intensity of the light for improved observation (detectability) of sea lice with respect to fish skin. An embodiment of the disclosed light system comprises multiple LEDs, at least two LEDs providing a light colour with peaks in the range 490-540 nm (Cyan/Green) respectively 620-660 nm (Red).

A system and method for remote monitoring and command and control of one or many offshore aquafarms is provided. Operators are able to securely access web applications and services hosted in the cloud through which husbandry functions such as feeding fish, cleaning the cage and removing mortalities can be automatically scheduled and executed. Offshore aquafarms relay information, such as environmental sensor data and video feeds back to the cloud to be viewed by the operators.

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.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for the automated feeding of fish. In some implementations, a corresponding method may include obtaining meal configuration data including one or more parameters indicating a meal plan for feeding farmed fish; executing the meal plan based on the meal configuration data; receiving sensor data from one or more sensors during execution of the meal plan; and adjusting the execution of the meal plan based on the sensor data from the one or more sensors.

Generating consensus feeding appetite forecasts include providing a first feeding parameter data set associated with a first feeding parameter to a first feeding appetite forecast model and providing a second feeding parameter data set associated with a second feeding parameter to a second feeding appetite forecast model different from the first forecast model. The first feeding appetite forecast model is adaptively weighted with a first weighting factor relative to a second weighting factor for the second feeding appetite forecast model. An aggregated appetite score based on a combination of the first feeding appetite forecast model using the first weight factor and the second feeding appetite forecast model using the second weight factor. Further, a feeding instruction signal based at least in part on the aggregated appetite score is provided for modifying the operations of a feed control system.

The invention relates to a composition comprising a mixture of at least one strain of a bacterium of the genus Bacillus and at least one strain of lactic acid bacterium for use in the prevention of infections in farmed oviparous animals.

System and methods for monitoring the growth of an aquatic plant culture and detecting real-time characteristics associated with the aquatic plant culture aquatic plants. The systems and methods may include a control unit configured to perform an analysis of at least one image of an aquatic plant culture. The analysis may include processing at least one collected image to determine at least one physical characteristic or state of an aquatic plant culture. Systems and methods for distributing aquatic plant cultures are also provided. The distribution systems and methods may track and control the distribution of an aquatic plant culture based on information received from various sources. Systems and methods for growing and harvesting aquatic plants in a controlled and compact environment are also provided. The systems may include a bioreactor having a plurality of vertically stacked modules designed to contain the aquatic plants and a liquid growth medium.
