Method for breeding insects, including the steps of: (a) providing a plurality of crates; (b) filling at least a portion of each crate of the plurality of crates with a substrate, containing feed stock, and immature phases of insects; (c) providing a climate area having an aeration system and placing the plurality of crates in the climate area; (d) providing a conveyor system for retrieving crates of the plurality of crates from the climate area and optionally for returning same thereto; (e) providing an observation system along the conveyor system for obtaining observations, including data and measurements; (f) providing a feedstock supply station along the conveyor system, downstream of the observation system; (g) aerating the substrate and the immature phases of insects with the aeration system, when in the climate area; (h) periodically retrieving at least one individual crate of the plurality of crates by the conveyor system from the climate area and passing it to the observation system; (i) obtaining an observation of the substrate and the immature phases of insects in the at least one retrieved crate; (j) interpreting the observation of a retrieved individual crate and determining one of a requirement for adding an amount of supplementary feed stock, and a reason to withdraw the insects from further breeding for harvesting or discarding from further breeding; (k) when an amount of supplementary feedstock has been determined in step (j), returning the retrieved individual crate to the climate area via the feedstock supply station; (l) when a reason for withdrawal has been determined in step (j), transferring the retrieved individual crate to one of an area for harvesting and an area for discarding; and (m) repeating the steps (g) to (l) for as long as at least one of the plurality of crates remains in the climate area.
