A deep water drawing step of drawing deep water that exists in a deep region of the sea to a surface region of the sea with an upwelling pipe (1); and a phytoplankton culturing step of culturing the phytoplankton in the upwelling pipe (1) are included to produce, as a basic producer of a food chain, a living marine resource, such as fishes and shellfishes, with phytoplankton produced in the phytoplankton culturing step.

A device and a method are disclosed for collecting and culturing fish embryos and evaluating combined toxicity of thiamethoxam and tetraconazole. An embryo collection component and an embryo culture component are provided on a base plate. The embryo collection component includes a collection tray detachably connected to a bottom of a culture tube. The embryo culture component includes a cavity plate with a stopper inside and a top plate provided with a culture well. A bottom of the culture well is provided with a leakage hole; and after the top plate is installed into the cavity plate, the stopper occludes the leakage hole. The new device is used to carry out the combined toxicity effect test of thiamethoxam and tetraconazole on zebrafish embryos, which can be used to avoid development of pesticide mixtures that have a good preventive effect but pose increased toxicity risk to the ecological environment.

Netting suitable for use in aquaculture which has a half mesh size of 5-100 mm measured in accordance to ISO 1107:2017 and includes cord having a diameter of 0.5-8 mm, wherein the cord includes films of ultra-high molecular weight polyethylene, the films having a width of 0.5-10 mm. It has been found that the use of cord based on films of ultra-high molecular weight PE (UHMWPE) results in nets with improved fouling resistance compared to nets based on conventional ultra-high molecular weight gel-spun monofilament or multifilament yarn. The netting is easier to clean than netting based on conventional ultra-high molecular weight gel-spun monofilament or multifilament yarn. Not only is less frequent cleaning required due to less fouling, the cleaning steps themselves can be carried out at lower water pressure in the high-pressure cleaning apparatus. This results in less damage of the nets during cleaning and lower water consumption.

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.

An interactive fish tank system includes a nozzle array provided in a water tank, wherein a plurality of bubble nozzles from which bubbles are emitted are arranged in the nozzle array; a computing device configured to receive user action information inputted from at least one user action input device, generate bubble conversion information by which characteristics of the user action information are expressed as bubbles generated from at least one of the plurality of bubble nozzles, and generate a control signal for supplying air to emit bubbles corresponding to the bubble conversion information; and an air injection device connected to the plurality of bubble nozzles through hoses, wherein the air injection device supplies air to at least one of the plurality of bubble nozzles based on the control signal.

The present disclosure generally relates to compositions, methods, systems to address stress, starvation, improved health, water quality, productivity and life expectancy of fishes; for both Ornamental fishes and Edible fishes. They enable close to 0% mortalities during transportation and throughout the distribution chain of the Aquaculture industry. The product serves as probiotic, prebiotic, improves water quality due to which lesser than prescribed amount of water can be used and water is changed with lesser frequency. Proportions and components of the compositions, the methods and systems could be varied and customised. The composition(s) comprise of bacteria with Accession Numbers: MCC0148, MCC0149, MCC0150. There are other probiotic bacteria which could be used in the composition(s) in a prescribed manner. The applications are throughout the distribution chain of Aquaculture industry and production unit of the product could be made an integral setup of farms, aquariums, warehouses.
