We evaluated cui-ui, Chasm&es cujus, swim-up success, time of hatching and swim-up, and size of larvae at swim-up under four fluctuating temperature regimes (8.9-15.0,12.2-X3.3,15.0-21.1, and 17.8-23.9" C). The greatest swim-up success was at the 8.9-15.0" C regime and the lowest at the 15.0-21.1" C regime. Hatching and swim-up time varied inversely with incubation temperature. The largest (and presumably the most fit) larvae were in the 8.9-15.0" C treatment, whereas the smallest were in the 17.8-23.9" C treatment. Cui-ui appeared best adapted to the coolest of the four temperature regimes.
