Dear Meghan,

Attached, please find the monthly summary of marine turtle removals for December 2009. In December, we captured twenty four (24)

Caretta caretta , and twenty four (24)

Chelonia mydas at the intake canal of the St. Lucie power plant on Hutchinson Island. On December 28, a sub-adult loggerhead was found with deep lacerations to both rear flippers caused by a shark attac

k. After consultation with FFWCC personnel this turtle was transported to the Marinelife Center in Juno Beach by Inwater Research Group biologists and was determined to be non-causal to power plant operation. On the same day, a sub-adult green turtle was captured and found to have multiple fresh cuts and scrapes to the head exposing the skull. This event was considered causal to power plant operation as a result of injuries sustained during entrainment through the intake pipe. This turtle was transported by IRG biologists to the Marinelife Center in Juno Beach as a cautionary measure of a possible skull fracture and/or concussion.

Throughout the month of December the 5" barrier net experienced light loads of algae that entered into the intake canal. This temporary barrie r has effectively kept turtles from moving further down the canal. A permanent fix to the primary net continues to remain in the design phase.

Tag numbers and morphometric data for all turtles are attached. Also, attached is a spreadsheet of all captures, mortalities, injuries and causal events delineated by species and month/year to date for 2009. This spreadsheet also includes and tracks fresh scrapes incurred on captured turtles for the month of December as well as 2009 year end totals and percentage.
