Technology - Incubating tray

Incubating trays with slip compartments and slit grooves

This system was developed in California and is implemented by producers who work with very high quality eggs and/or where large broods, especially fry are hatched. The trays can be delivered with 2, 3 or 4 compartments. Each compar-tment can hold up to 20,000 salmon eggs or 12,000 trout eggs.

The eggs are emptied out on the longitudinal grating. After hatching the fry fall through the grating and the yolk sacs either rest on the grating or are washed away via the sloped overflow grating. It is now easy to suck away the yolk sacs without damaging the fry.

The slit groves are situated on the bottom of the incubation trays, and the fry stay here to feed.

This has the advantage that the fish remain relatively reposeful and do not use up valuable energy by unnecessary movement. Feeding is also a lot easier.
