3 . 1 . 2 Fish Population Censusing <br /> Fish population censuses will also be collected annually for three years post-construction <br /> in project and control areas and will also include at least one pre-construction census . The <br /> point-count method (Bohnsack and Bannerot 1986) will be used for fish assessment. This <br /> method has the advantage of gathering quantitative data in a relatively short time in a <br /> very repeatable pattern that is relatively insensitive to differences in habitat structure. <br /> Each census will have duration of 5 minutes and a radius (the distance from the stationary <br /> observer) of 10 feet. Four point counts will be collected in the vicinity of the <br /> photoquadrat stations at R- 8 , R42, and R- 16 . A complete fish census will thus consist of <br /> 36 five-minute counts in the project area and 24 in the control area. All counts may be <br /> lumped together to compare fish populations overall between the project and control <br /> areas, or data may be separated by position along the transects (inner, middle, and outer) <br /> to determine the offshore extent (if any) of project effects . Data from these types of <br /> censuses are rarely normally distributed, so the Wilcoxon Rank-Sum or a similar <br /> nonparametric test will be used for significance testing. <br /> 3 .2 Marine Turtle Foraging Habitat Monitoring <br /> The effects of beach restoration projects on marine turtle foraging habitat have never <br /> before been addressed, although foraging turtles and their habitat are widely distributed <br /> in the nearshore environment. This section of the proposed Plan will directly address the <br /> effects of the proposed project in Sectors 1 and 2 on , the abundance of juvenile green <br /> turtles in the nearshore foraging habitat. It is further proposed to initiate directed <br /> research to determine the distribution and abundance of foraging turtles throughout the <br /> nearshore environment of the County. <br /> 3 . 2 . 1 Netting Studies <br /> To directly assess the potential effects of beach restoration activities on turtles in <br /> nearshore reef foraging habitats, the applicant will utilize the data that has been collected <br /> by turtle researchers at the University of Central Florida (UCF) . UCF researchers have <br /> been conducting netting for over a decade in the nearshore directly offshore from the <br /> proposed Sector 1 and 2 project area. The extensive Catch Per Unit Effort (CPUE) data <br /> they have collected since 1989 can serve as a baseline from which project effects can be <br /> assessed. The UCF effort, despite the valuable data collected, has never had dedicated <br /> funding. Indian River County proposes to fully fund the nearshore reef netting effort in <br /> the summer following construction and in two subsequent summers and to provide <br /> funding for data analysis and report preparation on the effects of the project on foraging <br /> turtle CPUE . <br /> 13 <br />
