ABSTRACT:
Artemia (14,90) are kept under such conditions as high density in a flowing aqua-culture (2) that either nauplii (90) or cysts (14) are deposited as offspring (14,90).
A treatment inducing cyclic cysts production consists of a cyclic reduction of the oxygen concentration of the flowing aqua-culture (2).
A device (1,44) for depositing only one selected type of offspring (14,90) comprises for the production of cysts (14) inducing means (12,53,64,67) for the cyclic reduction of the oxygen concentration.
A packing (67) of such offspring (14,90) is provided with a label (68) indicating a specification predetermined by the conditions the flowing aqua-culture (2) had been operated at.
Methods for feeding Artemia (14,90) are characterized by the use of agricultural derivatives (7) and/or chicken manure (7).
A method for preparing food (14,90) is characterized by the use of nauplii (90) and/or cysts (14) produced in the flowing aqua-culture (2) and/or by the use of particles coated with a food additive.
