Project Summary

This study was designed to address fundamental questions concerning relative abundance, population dynamics, FP rates, and movements of marine turtles in the southern Indian River Lagoon (IRL) system. The southern portion of the IRL supports populations of both loggerhead and green turtles. The mean SCL of green turtles here is more than 10 cm larger than that in the northern IRL system. FP rates are comparable to those to the north but higher than the rates at the nearby St. Lucie Power Plant. The researchers seek to expand sampling to the south of Jenning’s Cove in order to obtain a more comprehensive picture of differences in turtle populations in different areas of the Indian River Lagoon.
