Introduction 

Utila is one of the Bay Islands of Honduras located in the Caribbean Sea.  Over 400 species of reef fishes have been identified during REEF Fish Surveys in Utila.

25 most common species in Utila

The following ranking is based on the results of 1738  REEF Fish Surveys covering a bottom time of 2013 hours and 11 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.
