Sampling and growth measurements
Surveys of decapod species distributions in Quebrada
Prieta have been carried out since 1988 as part of the
Luquillo Long-Term Experimental Research (LUQ-LTER)
Program. Distribution, abundance and reproductive status
of freshwater decapods in six pools along a 1200 m
stretch of stream channel were sampled at least biannually.
Three pools distributed along an altitudinal gradient
(305 m, 360 m, and 433 m) were selected for our
current studies on growth rates and were during 1997–
2007.
