A recirculating aquaculture system using a biofloc fermenter and aquaponics may include a breeding water tank that breeds farmed fish, a drum filter that filters breeding water drained from the recirculating aquaculture system; an automatic filtration system in which the breeding water of the drum filter is moved and purified; a biofloc fermentation system that supplies and mixes oxygen to backwash water of the automatic filtration system; and a plant cultivation system that cultivates plant with the breeding water mixed with stable and high-concentration oxygen moved from the biofloc fermentation system.

A system for causing an upwelling to create a fishery without altering thermoclines in a body of water, having: an electric pump housed in a floating buoy; and a heat exchanger hose having a plurality of protrusions; wherein the heat exchanger hose and the electric pump are configured to pump nutrient-rich water from a first depth of the body of water to a second depth of the body of water closer to a surface of the body of water than the first depth; wherein the plurality of protrusions is configured for transferring heat from surrounding waters to the pumped water; and wherein the system releases the pumped water only when it is warmed to around the ambient water temperature of the second depth of the body of water, such that the pumped water remains at the second depth without immediately sinking back down to the first depth.

Disclosed is a method and process for manifesting sustainable improvement in fisheries productivity in Ocean waters. This method and process includes (1) selecting a location of the Ocean that is considered both High Nutrient Low Chlorophyll (HNLC), (2) that the location is within proximity to fisheries feeding grounds or migratory routes or within areas that are considered to be fish feeding areas, (3) within this location, a surface sea height anomaly (Ocean Eddy) is defined using satellite s.s.h. data, and (4) applying a fertilizer that contains an Iron compound within the Ocean Eddy.

A method of identifying fertilized fish eggs (200) in a sample of eggs (104) taken from a batch of incubating fish eggs is disclosed. The method includes the steps of treating the sample, within a period of time from initial fertilization of the batch, with a fixative (106) bringing an outer membrane of the eggs at least partly transparent and/or a blastodisc of the eggs at least partly opaque. The method further includes the step of capturing at least one image of individual eggs of the sample depicting the blastodisc of the egg, analysing the at least one image for detecting divided cells in the blastodisc, and identifying each egg associated with an image showing divided cells in the blastodisc as a fertilized egg. An associated system and a fish egg analysis apparatus are also disclosed.

A shipping container that includes a greenhouse mounted above an aqueous tank or tanks. Aquaponics fruits and vegetables grow in greenhouse in vertical and horizontal grow systems, while fish are grown in the tanks. Water flows between all plants and fish with no soil. The system is run by a computer automation system which operates on data obtained by various sensors and control components that include automated control valves, fish feeders, temperature and water flow measurements. The container can be operated from an established grid or can run off-grid with solar or other renewable energy sources. Part of the water needed for the system can be collected from rainfall. All necessary components except for the water, fish and plant seedlings are delivered in the shipping container.

A depuration process is employed for removing off-flavor contaminants from fish through an advanced oxidation process. Before the fish is harvested, the fish is transferred to a depuration tank or zone containing water. Off-flavor compounds leach from the tissue of the fish into the water in the depuration tank or zone. The water in the depuration tank or zone is circulated through an advanced oxidation reactor that, through an oxidation process, reduces the concentration of the off-flavor contaminants in the water.
