An aquarium cleaning device for cleaning an inner surface of an aquarium wall includes a flexible cleaning body and a flexible handle member. The cleaning body and the handle member are magnetically attracted to each other. The flexibility in the cleaning body and the handle member allows the cleaning device to contour and conform to curved surfaces in the aquarium tank. The flexibility of the cleaning body and handle member are achieved by areas of flexibility having alternating recesses and fins.

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.

Method for air drying a fouled net portion of a net comprising the fouled net portion and a clean net portion in a circular sea pen. The method includes the steps of: a) fastening lifting posts to the pen on a drying side; b) attaching slidingly internal ropes to the net; c) fitting winches to the lifting posts on a drying side; d) connecting an energy source to the winches; e) releasing a suitable part of a clean net portion from a handrail; f) fastening the internal rope to a winch; g) bringing a part of the fouled net portion into the air by pulling the internal rope with the winch; h) fastening a part of the fouled net portion to the handrail; and i) repeating steps e)-h) until the complete fouled net portion is lifted into the air. The invention regards also lifting posts to carry out the method.

An apparatus for cleaning aquaculture nets underwater. The appartus employs a propeller housing with a centrally disposed axis with a plurality of propeller blades extending therefrom. An outer perimeter ring secured to an outer tip of each propeller blade with a plurality of knuckles secured to the outer perimeter ring. Each knuckle including a curved surface constructed and arranged to strike the aquaculture net upon rotation of the blades for removal of growth by impact and shaking of the aquaculture net.
