Introduction 

The Dominican Republic is a nation on the island of Hispaniola, part of the Greater Antilles archipelago in the Caribbean Sea. The western third of the island is occupied by the nation of Haiti. Over 320 species of reef fishes have been identified during REEF Fish Surveys in the Dominican Republic.

25 most common species in the Dominican Republic

The following ranking is based on the results of  943 REEF Fish Surveys covering a bottom time of 984 hours and 38 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.
