Marine Turtle Removal Monthly Summary November 2013
Dear Meghan,
Attached, please find the monthly summary of marine turtle removals for November 2013. This month, we captured eleven (11) Caretta caretta and twenty-six (26) Chelonia mydas in the intake canal of the St. Lucie power plant on Hutchinson Island. There were two mortalities and two sea turtle were sent for rehabilitation during the month of November.
On November 14th, a severely decomposed subadult loggerhead sea turtle was removed from the top of the temporary 5-inch barrier net. There was no salient cause of death. After consultation with the Florida Fish &
Wildlife Conservation Commission (FWC), this incident was determined to be non-causal to power plant operations and the turtle was buried behind the dune. On November 15th, a subadult loggerhead sea turtle was removed from the tangle nets that was later sent to a rehab facility. This turtle was slightly underweight and apparently too lethargic to be released. After consultation with FWC, Inwater Research Group (IRG) biologist transported the animal to the Loggerhead Marinelife Center (LMC) in Juno Beach for rehabilitation. This was deemed a non-causal stranding. On November 26th, a juvenile green turtle was found underwater on the temporary 5-inch barrier net by Underwater Engineering Services divers during a net cleaning. The turtle was recovered postmortem during a severe algae event that temporarily drug the 5-inch barrier net underwater. The animal was kept on ice and held for necropsy by Nancy Mettee, DVM. According to the necropsy report, forced submergence (drowning) was the likely cause of death based on the overall good condition of this turtle.
This incident was considered causal to plant operations and counts against the take limit established by the most recent Biological Opinion set forth by the National Marine Fisheries Service. On November 30th, a juvenile green turtle was captured in the tangle nets that had fishing line in the mouth and appeared to be hooked deep in the throat. The turtle also had extensive flipper and carapace damage from an old healed injury. After consultation with FWC, IRG transported the turtle to LMC for rehabilitation. This last incident was not considered causal to power plant operations.
The scheduled short-term power plant outage that began on September 29th ended in the beginning of November. Throughout the month, the 5-inch barrier net experienced severe loads of algae that entered into the intake canal system; whereas jellyfish entrainment has been light-to-moderate. There were two severe algae 1
intrusions, one on the 16th and the other on the 26th of the month. Both times, Underwater Engineering Services (UESI) was called upon to deploy divers, sometimes on a 24-hour basis, to inspect and clean the 5-inch barrier net. In addition, Inwater Research Group biologists ramped up canal monitoring and reporting as well as proactive turtle capturing efforts in response to these periods of heavy algae entrainment. Unfortunately, the weight of the algae overwhelmed the temporary 5-inch barrier net during the second severe algae event and the net became submerged for approximately 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> before being restored by UESI dive teams. The temporary barrier net was submerged by up to ten inches. In addition, partial occlusion of the nets surface area by algal matting resulted in increased velocity where water still flowed through, creating the potential to trap turtles by pinning them against the net. During this time period, a juvenile green sea turtle made it past the 5-inch net.
The turtle eluded capture until it was recovered from the intake wells inside the power plants protected area on December 1st. The turtle was given a health assessment, measured, photographed and released in good condition later that morning. No other turtles have been observed beyond the 5-inch net. Florida Power &
Light has moved beyond the design phase for a permanent 5-inch barrier net and awarded the contract for its installation with an expected completion date in 2014.
The tag numbers and morphometric data for all turtles captured during the month have been included with this report (see attachments/addendums). Also included is a spreadsheet for all captures, mortalities, injuries, and causal events delineated by species and by month for the year 2013. In addition, this spreadsheet also tracks fresh scrapes incurred on captured turtles for the current month, as well as the entire year. An additional Excel spreadsheet was added this year that tracks all causal injuries and mortalities incurred by sea turtles at the St.
Lucie Plant since 2001.

- 7. RECAPTURE. Turtle was removed from the intake canal, tagged and released at Hutchinson Island on 5/9/13 and 11/19/13. Turtle had minor healed flipper damage.
- 8. STRANGE TAG (PIT tag #467D450E35 in left front flipper & Inconel Tag #RRS228 in left rear flipper).
Turtle originally captured in a pound net in Carteret County, North Carolina on 5/19/06. Sexed by the National Marine Fisheries Service via laparoscopy when originally captured (male). Two new inconel tags inserted on this capture event (front flippers).
- 9. STRANGE TAG (PIT Tag #982000190653268). "Kingston" was originally captured in Cape Cod, MA during a cold-stun event. The animal was rehabilitated by the Loggerhead Marinelife Center of Juno Beach and released on 4/19/13.
- 10. RECAPTURE. Turtle was removed from the intake canal, tagged and released at Hutchinson Island on 2/17/10, 10/8/13 and 11/24/13. New inconel tag (EEP361) inserted today in the right front flipper.
- 11. DEAD (CAUSAL MORTALITY). Stranding# RCW131126-01. The turtle was found underwater on the temporary 5-inch barrier net by Underwater Engineering Services divers while cleaning the net. The turtle was recovered postmortem during a severe algae event that temporarily drug the 5-inch barrier net underwater. The animal was kept on ice and held for necropsy by Nancy Mettee, DVM. According to the necropsy report, forced submergence (drowning) was the likely cause of death based on the overall good condition of this turtle. Sex determined from necropsy (female).
- 12. REHAB (NON-CAUSAL). Stranding# RCW131130-01. The turtle had fishing line in the mouth and appeared to be hooked deep in the throat. The animal was also missing the entire left front flipper (healed).
Two large pieces of the carapace were missing on the right side of the body from an old healed injury (large portions of the 1st, 3rd and 4th right costal scutes missing). Inwater Research Group biologists transported the turtle to the Loggerhead Marinelife Center in Juno Beach for rehabilitation.
