Welcome to the 2022 Fisheries and Aquatic Sciences
Graduate Student Symposium!

Austin Cary Forest

March 15, 2022

The Graduate Student Symposium (GSS) is a department-funded, student-run event that has occurred annually since 1998. The GSS is designed to provide a supportive environment where students in the Fisheries and Aquatic Sciences program (FAS) can hone their communication skills and receive feedback on their research from peers, staff, and faculty. Student participants travel from FAS facilities across the state to share their research with other members of the UF community; many of us look forward to the GSS for that very reason.

The format of the GSS has evolved over the years and is currently a single-day event held at the Austin Cary Learning Center. Student presenters are able to choose between full-length talks, speed talks, or poster presentations. Interspersed between student presentation are professional TED talks given by faulty and post docs.

2022 Fisheries and Aquatic Sciences Graduate Student Symposium

Austin Cary Forest
March 15, 2022

Abstract and registration deadline is February 18, 2022

Oral presentations will either be speed talks or full-length talks. Full-length talks will be scheduled for 15-minute time slots. Your talk should be 12 minutes in length, allowing for 3 minutes of questions. Speed talks will occupy the entirety of a 5-minute timeslot (i.e., no questions). We will have moderators to assist with timing and will adhere to our schedule.
Posters should be no more than 36*48 inches in dimension.

Please follow the directions below for formatting your abstract:

Abstracts should be submitted to the following Dropbox link

If the presentation abstract is not the following format, it will be returned with instructions to fix it. Please follow the guidelines for consistency and reduced work for your fellow students in preparing the GSS program. If you have any questions email Casey Murray or Diana Perry Thanks!

Please use Times New Roman and 12-point font for the entire abstract unless otherwise specified. The title should be bold. The presenting author should be underlined. If there are multiple authors from multiple institutions for the abstract, please indicate them with corresponding superscript numbers. The affiliated institution(s) should be in 10-point font. The corresponding author email (label in bold) should be provided. Abstracts should be no longer than 250 words. Finally, at the end of your abstract, please provide what type of presentation you were assigned.

Otocinclus vittatus are small, South American armored catfishes belonging to the family Loricariidae and popular in the private aquaria market. Currently, all O. vittatus are collected from the wild and captive reproductive methods have proven elusive for commercial fish producers. The Florida Tropical Fish Farms Association (FTFFA) prioritized O. vittatus as a potential species to diversify and strengthen the Florida ornamental aquaculture industry. Little is known about spawning triggers and no methodology has yet been determined to reliably spawn O. vittatus. Other South American ornamental species have successfully been triggered to spawn via a simulation of a dry season followed by a wet season as would be found in their native range. Water hardness and temperature are two of the water quality parameters commonly manipulated to trigger this simulated change in seasons. Here we present the preliminary results of the manipulation of these water quality parameters, and the ongoing investigations. In addition, precise control of spawning events allows for producers to make stocks available outside of the normal spawning season and reduces labor and resources by allowing them to determine when best to spawn a particular species of fish. Hormone injections, such as Ovaprim a gonadotropin-releasing hormone with a dopamine antagonist, are often used as spawning aids to control spawning events. We evaluate the use of the spawning aid Ovaprim and its efficacy with O. vittatus. Future research directions will also be addressed.

Dr. Jennifer Rehage, Florida International University

Jennifer Rehage

Dr. Jennifer Rehage is a coastal and fish ecologist and associate professor at the Institute of Environment and the Earth & Environment department. Studies in her research group focus on understanding how natural and human disturbances affects multiple aspects of the life of fish focusing on individuals, their behavior, populations, ecosystem role, and interactions with anglers. Over the past decade at FIU, Dr. Rehage has been studying how hydroclimatic variation effects fish and the recreational fisheries they support in the Everglades and throughout South Florida. Research has focused on Common Snook, Florida Largemouth Bass, Bonefish, juvenile Atlantic Tarpon and Jack Crevalle. Studies examine the interacting effects of natural flow regimes, climate, and management decisions on fish space use, distribution and populations, and involves recreational anglers, and local ecological (angler) knowledge.
