The present invention relates to a method of aquaculture of at least one farmed organism, such as fish, shrimp or any organism suitable for farming in an aquatic environment. There is provided a method of aquaculture of at least one farmed organism, the method comprising steps: (i) providing an aquatic environment comprising at least one farmed organism, phytoplankton and bacteria; (ii) providing at least one phytoplankton nutrient and at least one bacteria nutrient during a first predetermined period, allowing phytoplankton and bacteria to grow in a first predetermined phytoplankton:bacteria ratio of more than 1; (iii) providing at least one phytoplankton nutrient and at least one bacteria nutrient during a second predetermined period, allowing phytoplankton and bacteria to grow in a second predetermined phytoplankton:bacteria ratio, wherein the second predetermined phytoplankton:bacteria ratio is lower than the first predetermined phytoplankton:bacteria ratio; and (iv) providing at least one phytoplankton nutrient and at least one bacteria nutrient during a third predetermined period, allowing phytoplankton and bacteria to grow in a third predetermined phytoplankton:bacteria ratio, wherein the third predetermined phytoplankton:bacteria ratio is lower than the second predetermined phytoplankton:bacteria ratio, thereby allowing the at least one farmed organism to grow.

A shellfish microhatchery system includes a laboratory workstation; a reservoir tank with an outlet; a larval tank; and a nursery tank. the larval tank and the nursery tank receive water from the reservoir tank outlet. The nursery tank receives larvae from the larval tank. A method of producing shellfish seed for a farm comprises obtaining sperm and eggs from local broodstock; spawning the sperm and eggs to produce fertilized eggs, aerating the fertilized eggs in a larval tank until the larvae metamorphose into veliger larvae; filtering the veliger larvae; determining a stocking density of the veliger larvae; separating larvae having a shell height of at least about 224 microns; introducing the pediveliger larvae to a cultch-containing vessel; separating larvae having a shell height of at least 300 microns; introducing the separated pediveliger larvae to a grow-out vessel; and growing the separated pediveliger larvae to a predetermined size.

An aquaculture system can include an aquafarm with one or more aquatic pods of aquatic organisms and a remote device to manage the aquafarm. An aquatic pod may be associated with an aquatic structure with a buoyancy system and a control device to automatically perform daily farming functions. The aquatic structure may include an enclosure to hold the aquatic organisms. The control device may be configured to use a smart buoyancy assistant to control the buoyancy system and to determine the farming task to perform in response to environmental stimuli. The remote device can receive data representing crop metrics, harvest results, and sensor data. The remote device can aggregate data from multiple aquatic pods and correlate the data to generate aquaculture models to improve the harvest results. The remote device can generate overview and maintenance reports for the aquafarm.

Provided are a closed rearing method and a closed rearing apparatus which can decompose and remove ammonia contained in rearing water without supplying an excessive amount of ozone and can also suppress generation of toxic oxidants. In a closed rearing method for aquatic organisms and marine animals involving an ozone treatment for decomposing ammonia in rearing water by supplying a gas containing ozone into the rearing water, the closed rearing method is characterized in that aquaculture is performed in a closed environment by a first step for determining the ozone concentration of the gas and pH conditions of the rearing water suitable for reducing the amount of generation of toxic oxidants by previously treating the rearing water to reduce ammonia contained therein to the target value by using an apparatus for actually conducting the treatment and a second step for conducting an ozone treatment of the rearing water according to the suitable ozone concentration and pH conditions determined in the first step.

A method of growing shellfish is disclosed. The method comprises obtaining a support tray (I) with recesses (7) where at least some of the recesses (7) incorporate means adapted to create a deliberately formed alphanumeric, written or pictorial mark on the shellfish as it grows. Shellfish spat are attached to at least some of the recesses (7) and the tray (I) is placed in water so that the spat grow into substantially mature shellfish within the recesses (7). The spat each grow generally in the shape of their respective recess (7) so that the mark is created on the shellfish as it grows.
