25 most common species in Cayman Brac
The following ranking is based on the results of 274 REEF Fish Surveys covering a bottom time of 364 hours and 7 minutes. (REEF Geographic Zone Report. June 3, 2009). The species are ranked by the percentage of surveys in which a species was observed. Abundance of fishes in REEF Fish Surveys are estimated using the following categories: 1- single =1 individual, 2-few = 2- 10 individuals, 3-many = 11-100 individuals, and 4-abundant > 100 individuals. The mean numeric abundance (ranging from 1 - 4) was calculated for each species.. The mean abundance category is determined as follows: mean abundance category 0 - 1.49 = single, 1.50 - 1.99 = single-few, 2.0 - 2.49 = few, 2.5 - 2.99 = few-many, 3.0 - 3.49 = many, 3.5 -3.99 = many-abundant, and 4.0 = abundant.
