| Abstract |
1. A simple cylindrical hatching and separator box is described for Artemia salinanauplii (and other phototactic invertebrates), in which the "corner seeking effect" responsible for poor separation is avoided, and from which nauplii can be recovered very conveniently. 2. Separation is achieved by partly unscrewing an internal and closed cylinder from its fixed counter-part glued to the bottom of the box, till two slits are freed through which the nauplii migrate from the darkened internal hatching cylinder into the illuminated exterior compartment. Rescrewing the former cylinder separates the larvae from debris and unhatched eggs. |
