| Note(s): |
Ontogenetic changes in phototaxis of queen conch Strombus gigas (Linne) veligers were studied in the laboratory and in field mesocosms. In the laboratory, larvae showed a strong positive phototaxis and negative geotaxis during early stages. Positive phototaxis decreased as a function of age from 100% positive response at Day 1 to ≈50% at metamorphic competency. In field mesocosm experiments, vertical position correlated significantly with light intensity. Vertical migration patterns were not affected by the presence or absence of solar UV, and did not vary as a function of ontogeny. The overall pattern of vertical distribution in the field appears to be controlled by negative geotaxis moderated by negative phototaxis at high light intensities.
