Dataset title: Common snook (Centropomus undecimalis) movements within the Shark River estuary (FCE), Everglades National Park, South Florida from February 2012 to Present Dataset ID: LT_TDCS_Rehage_004 Research type: Long-term Dataset Creator Name: Dr. Jennifer Rehage Position: Principle investigator Organization: Florida Coastal Everglades LTER Program Address: Florida International University University Park ECS 119 Miami, FL 33199 USA Phone: 305-348-0181 Email: rehagej@fiu.edu URL: http://www2.fiu.edu/~rehagej/ Metadata Provider Organization: Florida Coastal Everglades LTER Program Address: Florida International University University Park OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: http://fcelter.fiu.edu Dataset Abstract Movements of common snook (Centropomus undecimalis) in the Shark River estuary were measured using passive acoustic telemetry. Snook were fitted with a V-16 acoustic transmitters, transmitters emit an ultrasonic pulse at random every 60 – 180 seconds that can be interpreted by autonomous listening stations dispersed throughout the Shark River estuary. Once a listening station detects a transmitter, it records a time of detection and a unique tag ID. Dataset Purpose I aim to determine the relative importance of interannual variations in the hydrologic regime on tropical fish I) reproduction II) juvenile recruitment, and ultimately III) angler catch rates. I aim to conduct a six year field study tracking reproductive and recruitment dynamics of a popular tropical recreationally targeted species, snook. I will then relate these reproductive and recruitment dynamics to factors of the hydrologic regime that may vary across years.

Snook were surgically fitted with a Vemco V16 transmitter (Vemco, Halifax, NS, Canada). Transmitters were set to emit a unique series of pulses for each shark at a random interval between 60 and 180 s (mean emission interval = 120 s). Movements of acoustically tagged sharks were tracked within an array of 43 Vemco VR2 and VR2W acoustic receivers. In situ measurements revealed mean detection ranges of receivers were c. 500 m. Each receiver was attached to a PVC pipe set in a 10-kg cement anchor. Data from receivers were downloaded every 3–4 months for the duration of the study, and batteries were replaced as needed. Method Step Description Fish were fitted with a V-16 acoustic transmitters. Transmitters were implanted surgically into the body cavity of fishes following IACUC Protocol #200135. Transmitters emit an ultrasonic pulse at random every 60 – 180 seconds that can be interpreted by autonomous listening stations dispersed throughout the Shark River estuary. Once a listening station detects a transmitter, it records a time of detection and a unique tag ID. Data were downloaded off of receivers every two months Citation Matich, Philip 2014-01-01.

Boat electrofishing is an effective sampling technique in freshwater habitats, including the Everglades, and has been used successfully to sample upper estuarine fish communities (Rehage and Loftus 2007). We conducted three replicate electrofishing bouts (timed sampling transects) at fixed locations in each site, each 200 m apart. For each bout, we ran the boat at idle speed at a randomly-selected creek shoreline and applied power for 5 min of time, during which two netters captured all immobilized fishes. We standardize power output to 1500 Watts, given temperature and conductance conditions measured at the beginning of each bout.

Prior to analyses, ‘false’ detections and were removed from the dataset. Keywords False detections Data checking Procedural Steps identify distance and time between fish detections determine if that distance is feasible for fish to travel in the duration between detections If impossible, false detection is deleted Instrumentation None Quality Control Detection data are managed and checked through software provided by VEMCO.
