| Anmärkningar | Sampling was done in 3 sites along the northwestern region (Havana reef, Herradura reef and Colorados reef). Sampling for each site was done in at least 15 randomly placed censuses (sampling units) in each of the 36 samples (combinations of bottom type, reef and season of the year). Present in 11.1% of the sites. Abundance was estimated using the stationary visual census technique of Bohnsack and Bannerot (1986) with some minor modifications. Nominal radius of observing cylinder was 5 m. | ||
