  • Fish egg incubator
    Patent number: 4014293
    Abstract: A fish egg incubator consisting of an upper removable egg tray having a sen bottom and a lower trough containing a rugose material substance is described. Water flows continuously over both the egg tray and rugose substrate. The eggs hatch out on the screen tray and the alevins fall through the mesh to the rugose substrate where they continue the development to the fry stage. At the proper development stage the fry migrate out of the rugose substrate and are carried out by the water stream and are collected.
