Marine Turtle Removal Monthly Summary February 2019

Dear Meghan,

Attached, please find the monthly summary of marine turtle removals for February 2019. This month we captured 38 Caretta caretta, 29 Chelonia mydas, and seven Lepidochelys kempii in the intake canal of the St. Lucie power plant on Hutchinson Island. Five sea turtles were sent for rehabilitation (all non-causal) and there were two causal mortalities during the month of February. As with all sea turtle strandings at the Saint Lucie Plant (alive or dead), the Florida Fish and Wildlife Conservation Commission (FWC) was consulted and strandings forms were filed with the state through the Sea Turtle Stranding and Salvage Network.

Five turtles were sent to rehabilitation facilities for non-causal injuries this month. An emaciated and lethargic subadult loggerhead was taken to the Loggerhead Marinelife Center (LMC) for Debilitated Loggerhead Turtle Syndrome.

Another subadult loggerhead, missing its entire left front flipper, was recovered from the primary barrier net and taken to LMC. An adult female Kemps ridley was also brought to LMC for shark attack injuries. A second shark attack victim, an adult female loggerhead, went to the Gumbo Limbo Nature Center. Lastly, a small subadult green turtle was dip-netted with monofilament line coming out of its mouth and wrapped around its front flipper (taken to Miami Seaquarium). All five rehab turtles were considered non-causal.

There were two causal mortalities this month. On February 4th, a juvenile green turtle was recovered by Underwater Engineering Services (UESI) divers while inspecting the primary 5-inch barrier net. The turtle was found against the bottom of the barrier net and was moderately decomposed (slippage of scales and foul smell). The turtle was only slightly underweight and there were no wounds or abnormalities that could explain the animal's death. On February 11th, a second fresh dead juvenile green turtle was found below the surface on the primary 5-inch barrier net by UESI divers (during net cleaning). This turtle was underweight and missing half of its right rear flipper from an old healed injury. Both turtles were held on ice and taken to Dr. Nancy Mettee, DVM for necropsy and causality determination.

Although the second turtle exhibited signs of nutritional compromise (likely a contributory factory in the death of the animal), both turtles were ultimately deemed causal.

On February 3rd, three juvenile green turtles were removed from the intake wells. All were in good condition and released the same day of capture. The following day, UESI inspected the primary 5-inch barrier net and discovered that there were gaps along the bottom of the net. The uneven accumulation of sediment along the base of the barrier net had exerted significant pressure on the net and altered its configuration. Under the direction of FPL, UESI has already begun the process of retensioning the primary barrier net in order to improve its performance. In the short-term, rocks were used to fill in any gaps near the bottom of the net and any uneven areas of mesh were patched. The routine quarterly net inspections on the first two barrier nets (the 5-inch and 8-inch A-1-A) did not reveal any other issues and no holes were found.

2 The primary 5-inch barrier net encountered severe loads of algae during the month. IRG biologists performed around-the-clock monitoring of the intake canal and barrier net system either as warranted by sufficiently high debris intrusion levels or whenever directed by FPL oversight personnel. Furthermore, UESI inspected the 5-inch and A-1-A barrier nets throughout the month and removed accumulated algae and debris as needed.

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 2019. In addition, this spreadsheet tracks fresh scrapes incurred on captured turtles for the current month, as well as the entire year.

Please feel free to contact me with any questions.
