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.

Examples of the disclosure provide for an apparatus for actively promoting marine life. The apparatus includes a datacenter implemented in a body of water and coupled to a network, a pressure vessel that houses the datacenter, and one or more components coupled to the pressure vessel and adapted to actively promote reef life and sustain a surrounding ecosystem.

The present invention provides processes for removing nitrogen species from fresh water or high salinity water recirculated aquaculture systems. The processes are based on physico-chemical treatments which are performed at ambient temperatures and at low pH values thus keeping the total ammonia nitrogen concentrations below a value which is considered detrimental for the growth or survival rate of cultured fish/shrimp.

A device for reducing the number of exterior parasites on fish, comprising a hollow cylindrical filter member (3) having an inlet and an outlet, the circumference of the inlet and/or outlet being provided with a nozzle (1a, 1b), wherein the nozzle comprises a substantially annular slit along the circumference of the inlet and/or outlet for ejecting a fluid towards the interior of the cylindrical filter (3).

The device for the migration of aquatic animals has a channel body with an upstream end and a downstream end as well as a longitudinal axis. The bottom of the channel body is provided with a cover layer made of natural bottom substrate and/or debris material and has a ridge running along the longitudinal axis. Plate-shaped lamellae are arranged in the channel body transversely to the longitudinal axis of the channel body. The lamellae have a downwardly open lower cut-out, which is limited at the top by a transverse element, wherein the cross-sectional area of the lower cut-out is dimensioned in such a way that the ridge of the cover layer may be accommodated in the lower cut-out. The upper edge of the transverse element has a preferably curved contour, which is inclined towards the centre of the channel and defines a lower boundary of an upper cut-out of the lamellae extending upwards from the transverse element.

A coral frag plug holder and system includes a main body and an interchangeable attachment device. The main body includes a first main end and a second main end. The first main end includes an opening configured to receive a coral frag plug. The second main end includes a main connector. The interchangeable attachment device includes a first attachment end and a second attachment end. The first attachment end includes an attachment connector configured to connect to the main connector of the main body. The second attachment end includes an attachment means configured to attach to a surface of an aquarium. Wherein, when the attachment means is attached to the surface of the aquarium, the attachment means positions the main body on the surface of the aquarium, whereby, coral frag plug is positioned on the surface of the aquarium.
