A hatching apparatus (incubator) for pelagic eggs, particularly marine fish specimens, with a container (11) where in a depressed section (13) there is a drainage tube (23). The container (11) is equipped with means (17, 15) which initiate water circulation through the lower parts (12) which extend downwards into a bottom chamber (13). This leads the dead eggs into the bottom chamber where they can be drained off, whilst fresh eggs are kept buoyant in the water and hatch evenly. Centrally in the container (11) there is a riser tube (15) with an opening just over the base section (12) to enable an air tube (17) to supply air to the lower end of the riser tube to create circulation. |
