    Bylaws and Pictures

    A two-part program

    1. Bylaws Changes - We have Bylaws changes to discuss and, hopefully, approve by a vote of the members present. The reasons for making the changes are outlined briefly in the President's Waves. Members can help speed up discussions by reading the proposed changes here.
    2. Pictures - Nils Jacobsen is putting together a presentation of photos from past trips. He is working on the presentation while I write this, so I am not sure what the final result will be. It will probably include his pictures from our recent Little Cayman trip. It may include pictures from Fiji, especially if we can get another Fiji trip scheduled for 2020. If we are lucky and he can find the time, we may get to see pictures from Cuba. And he has pictures from his African safari that may also make it into the presentation.

    Making Friends With Sharks Without Feeding Them
    By Jim Abernethy

    Jim Abernethy, an award-winning underwater photographer, author, filmmaker and conservationist. He is a pioneer in large predatory cageless shark encounters with some of the world's most notorious sharks. Scuba diving since his youth inspired his life's mission to spread the word about the importance of worldwide ocean conservation.

    For decades, Abernethy has been running photography/video expeditions to guide encounters with the world's largest predatory sharks. He pioneered shark encounters without a cage (day and night) with tiger sharks, great hammerheads, oceanic white tips, bulls, and lemon sharks. Jim’s tireless efforts to help save sharks around the world were part of the reason why the Bahamian waters were recognized as a shark sanctuary, in July 2011. This was a huge victory for sharks around the world.

    His award-winning marine life images are represented in galleries, nature & photography magazines, as well as his stock agent, National Geographic. Raising awareness about the need for conservation remains Abernethy’s primary focus when aiming his camera at wildlife subjects. Additionally, he has launched two separate series of books, in collaboration with award-winning author Jennifer R. Nolan, that seek to educate and empower others to join in key conservation efforts.

    Abernethy has hosted and been featured in many of the world's top nature filmmakers shows, such as Imax, National Geographic, BBC Wildlife, Animal Planet, and the Discovery Channel. His images are available at National Geographic Image Library. He owns the "Marine Life Art Gallery" in West Palm Beach, FL, where his captivating images and unique and educational books are available as well. When he's not below sea level, Jim is often seen piloting his flying inflatable boat (ultra-light), "Oversear," in order to capture nature at sea with his lens from an aerial perspective.

    While Abernethy is well known as a world-class photographer and passionate conservationist, it's his unique ability to bring divers up close to some of the largest predatory sharks safely, in turn inspiring them to become vocal and passionate ambassadors to save the sharks, that separates him from the rest.

    Abernethy is best known for the relentless pursuit of his life's mission: to save the planet's ocean creatures, starting with sharks, through his photography, books, films, and presentations. His colleagues have recognized Abernethy with four lifetime achievement awards for his relentless dedication to ocean conservation and the protection of sharks. He was the recipient of the Eleanor Fletcher Lifetime Conservation Achievement Award at the Go Blue Event in 2011, the Crest Award from Gumbo Limbo in 2013 and was honored with The Wyland Icon award in 2011. Last year he received the Shark-Con 2018 Conservation award for his relentless efforts saving sharks!

    Jim is the founder of three ocean conservation-based non-profits Operation Blue Pride, WildlifeVOICE and Project Seahorse for Kids. Operation Blue Pride helps veterans learn to scuba dive, while forming an army of advocates to take on ocean issues. WildlifeVOICE works with many entities, giving a voice for those who cannot speak. Presently, WildlifeVOICE is working to protect wildlife in the state of Florida from the Red Tide issues. WildlifeVOICE was the driving force in the Florida Fish and Wildlife Conservation Commission’s (FWCC) April 2018 decision to continue protecting the critically endangered goliath grouper.

    Believing that science is critical to saving our wildlife, Jim works with a number of scientists by providing them with the resources necessary for the collection of marine science data. To date, the fields of research to which Jim’s company has been able to assist include formal and informal studies of: sharks, sea turtles, dolphins, cephalopods, reef ecosystems and coral reefs just to name a few.

    Jim lives primarily at sea, in the Bahamas, running shark expeditions and wild dolphin encounters year-round on his boat, "Shear Water." He can also be found in Mexico running eco-tourism expeditions for whale sharks and manta rays. His dive business, Jim Abernethy's Scuba Adventures Inc., is based in West Palm Beach, FL.

    Dr. Stephen Kajiura is returning to give us more information about “Snowbird Sharks: Seasonal Abundance and Spatial Distribution of Blacktip Sharks (Carcharhinus limbatus) in Southeast Florida”

    He is a Professor in the Department of Biological Sciences at Florida Atlantic University. His area of expertise is the sensory biology of sharks and rays with an emphasis on the electrosensory system. In addition to his sensory physiology research, Dr Kajiura studies the massive seasonal aggregation of blacktip sharks in southeast Florida. He incorporates aerial surveys with tagging and acoustic telemetry to document the migration of these sharks along the US eastern seaboard.

    Dr Kajiura has conducted research for various agencies including the National Science Foundation, the Department of Defense, and the National Marine Fisheries Service. He has published over 50 papers in peer-reviewed journals and has presented numerous talks at scientific conferences. He has supervised a dozen graduate students and post-doctoral researchers, and has served on numerous thesis committees for students from around the world. Dr Kajiura maintains a strong public outreach service, primarily through television documentary appearances, and has served as an elected member of the American Elasmobranch Society Board of Directors.

    Dr Kajiura received his PhD in Zoology from the University of Hawaii, a MS in Marine Biology from the Florida Institute of Technology, and a BSc (Hons) in Marine Biology from the University of Guelph (Canada).

    Southeast Florida experiences an enormous seasonal influx of upper trophic level marine predators each year as blacktip sharks (Carcharhinus limbatus) migrate south to overwinter in nearshore waters. These sharks form aggregations ranging from a few individuals to thousands. The sharks are often found in very shallow water, only a few meters from popular swimming beaches which raises concerns about potential negative interactions. To quantify shark abundance and distribution, an aerial survey was conducted during peak season (December - April) from 2011-2017. A low altitude (150m) survey flight was flown from Government Cut (South Beach, Miami) to Jupiter Inlet at approximately biweekly (2011-2014) or weekly (2015-2017) intervals. A high definition video camera recorded a transect from the beach to approximately 200m offshore. Segments of the survey transect were demarcated by inlets, and the number of sharks found within each segment was counted to calculate shark density. During the seven year study, the greatest shark density was consistently found in February and March. Although sharks were seen throughout the entire 132km length of the survey transect, significantly greater numbers of sharks were found at the northernmost third of the transect in Palm Beach County (Boynton Beach Inlet to Jupiter Inlet) where densities exceeded 1,000 sharks km-2. The habitat throughout the transect is largely consistent, so it remains unclear why the sharks are not distributed farther south. Southward migrating sharks might simply stop once they reach appropriate conditions and warming oceans might eventually restrict their migration to increasingly higher latitudes.

    Hammerheads and Shore-Based Shark Fishing

    Presentation by Hannah Medd

    Hannah Medd, founder of the American Shark Conservancy and marine biologist, has more than 10 years’ experience conducting applied research and conservation outreach for global and local shark and ray initiatives. She earned her Bachelors of Science in Marine Biology and Ecology at Florida Tech in Melbourne, Florida. She traveled to South Africa to complete her Masters of Science in Marine Biodiversity from the University of Cape Town, where she learned about many aspects of marine resource management, including research and academia, government and policy, socioeconomics and ecotourism.

    Endangered great hammerheads are popular species among divers and fishermen alike. This species is prohibited from landing in Florida waters and yet seem to be facing a poorly-understood threat, shore-based shark fishing. As part of American Shark Conservancy's research program, this project will describe the impact of this activity on the species and use these data to help inform policy.
