Stakeholder groups for freshwater include agriculture, South Florida populations, and the natural environment and the ecosystem services that they provide. One ecosystem service invaluable to South Florida is the provisioning of coastal recreational fisheries. This ecosystem service generates approximately 8 billion dollars in angler expenditures in Florida alone. However, the interplay between the provisioning of fisheries and the allocation and input of freshwater to coastal systems is largely unknown. One such way that recreationally important fishes could be impacted by changes in freshwater inputs to coastal systems is through the availability of food. Previous research has shown that seasonal rainfall patterns and freshwater management create spikes in prey availability for important recreational fishes such as Common Snook (Centropomus undecimalis) and Largemouth Bass (Micropterus salmoides). These prey pulses are restricted to the most inland reaches of the estuary. However, two important questions remain unanswered: 1) How far away do snook and bass move to take advantage of this prey subsidy? 2) Do these spikes in prey availability increase the reproductive output of snook? In order to answer these questions, we use acoustic telemetry to track the movements of key recreational fish species (Common Snook and Largemouth Bass) over multiple years (2012 – current) in the Shark River Estuary, Everglades National Park. Data provided by this study will be the first step in quantifying the importance of freshwater inflows to coastal fisheries. From a science perspective our research will provide valuable insight to how highly mobile species respond to pulses of prey across a patchy landscape, and how these temporary highly abundant resources will act to boost consumer populations. The value of pulsed resources to consumers have been identified as an important information gap in population ecology. 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.

Fish were surgically fitted with a Vemco V13 or V16 transmitter (Vemco, Halifax, NS, Canada). Transmitters were set to emit a unique series of pulses for each fish at a random interval between 60 and 180 s (mean emission interval = 120 s). Movements of acoustically tagged fish 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-13 or V-16 acoustic transmitters. Transmitters were implanted surgically into the body cavity of fishes following IACUC Protocol #201287. 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.
