An underwater observation device is proposed. The underwater observation device includes a case body having an inner space. The case body includes a first filtering portion, a first transparent portion, and a second transparent portion. The first filtering portion is configured to filter impurities in the water entering the case body. The first transparent portion and the second transparent portion are adjacent to the first filtering portion and are located on two opposite sides of the case body respectively. The first transparent portion and the second transparent portion are configured for a user to observe at least one object through the case body.

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.

The present invention generally relates to an aquatic farming system (200) comprising one or more stacked levels of an array of one or more aquatic farming modules (100). Each aquatic farming module (100) comprises an intermodal container (102) comprising a pair of opposing side walls (104) and a pair of opposing end entrances (106), and a housing structure (110) disposed in the intermodal container (102) and extending between the side walls (104) thereof. The aquatic farming module (100) further comprises a set of access doors (130) disposed at one or both end entrances (106) of the intermodal container (100), the access doors (130) actuatable planarly for selectively opening/closing the respective end entrances (106). Selective opening/closing of the end entrances (106) of the intermodal containers (102) in each stacked level facilitates user accessibility to the housing structures (110) in said stacked level for farming aquatic organisms.

A device (10) for trapping and killing marine organisms (14) such as animal plankton, salmon lice and other parasites, comprises a body (12; 12′) configured for submersion in water (15). The body (12; 12′) comprises at least one light source (16) configured and controlled for attracting said marine organisms, and an internal cavity (20) having an opening (20′) for fluid communication with at least a portion of the water. The light sources (16) are arranged inside the cavity (20) and arranged and controlled to emit light waves through said opening and into at least a portion of the water. At least one positive electrode (24; 24′; 24″; 32) is arranged in the cavity and electrically connected to a low-voltage power source (26; 27; 30), and at least one negative electrode (15a) is arranged in the water and electrically connected to said power source (26; 27; 30). The invented device generates, by means of electrolysis with the water (15), chlorine gas (21) at or in a region near the at least one positive electrode, and the chlorine gas (21) reacts with water inside the cavity to form hypochloric acid and hydrochloric acid (31).

A nutritional supplement is disclosed. The nutritional supplement may be included in a fish diet. The nutritional supplement may include a carrier oil; 22-30 wt. % Omega 3; and 8-20 wt. % Omega 7. In some embodiments, the carrier oil may be a vegetable oil. In some embodiments, the Omega 3 includes EPA and DHA fatty acids. In some embodiments, the Omega 3 includes is a mixture of EPA and DHA having ratios in the range of 1:10 to 10:1 wt. %.

Provided is a circulating aquaculture facility for saltwater ponds. The circulating aquaculture facility comprises a cultivation tank, a division plate vertically arranged in the cultivation tank to divide an inner cavity of the cultivation tank into a left inner chamber and a right inner chamber; a water inlet pipeline, water in the water inlet pipeline enters the cultivation tank through the left rectangular through hole of the cultivation tank; an outlet pipeline, sewage discharged from the right rectangular through hole of the cultivation tank is capable of entering the outlet pipeline; and an oxygen supply device which delivers oxygen to the inner bottom of the cultivation tank.

A method for detecting fish school hunger degree based on feeding behavior includes: detecting a water wave fluctuation driven by the feeding of a fish school using a water surface floating body; controlling a fish feeder by calculating water wave fluctuation intensity. The water wave fluctuation is detected by adopting a detection device associated with the water surface floating body.
