Introduction 

St. Vincent is the largest island in St. Vincent and the Grenadines located in the eastern Caribbean Sea, about half way between Puerto Rico and Trinidad and Tobago. Over 320 species of reef fishes have been identified during REEF Fish Surveys in St. Vincent.

25 most common species in St. Vincent

The following ranking is based on the results of  1667 REEF Fish Surveys covering a bottom time of 2329 hours and 35 minutes. (REEF Gopgraphic Zone Report, May 30, 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.
