Abstract: A tray system suitable for use with fish laying eggs in skeins provides a set of cassettes having opposed water-permeable faces that may clamp about the edges of the skeins to prevent them from coiling about themselves while exposing both sides of the skeins to flowing water. A regular form factor of the cassettes allows them to be closely stacked with small water flow gaps between them for high hatching density.
