	three methods for visually assessing reef fish

Reef fish assemblage survey results using Transect, Point, 
and Random in situ visual assessment techniques were 
evaluated and compared on a coral reef biotope off the 
southwestern coast of Puerto Rico. Parameters compared were: 
number of species, number of individuals, and species 
diversity (H'). Variability in observations between divers 
was not noted for any of the dependent variables while 
conducting the Transect method. Divers using the Random 
technique recorded the highest number of species per survey, 
while the assemblage parameters recorded using Transect and 
Point methods were statistically similar for most dependent 
variables. When the data were adjusted for amount of survey 
time and area it was determined that divers were more 
efficient in sampling numbers of individuals when using the 
Transect method.
