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.La présente invention concerne un procédé daquaculture dau moins un organisme délevage, tel que du poisson, des crevettes ou tout organisme pouvant être élevé dans un environnement aquatique.
