This is the second episode I have done about shark first aid, the first one acting as an extension to my surfing guide to sharks… and this one expanding on the topic to not only focus on potential attacks of surfers, but those we face in the shark tourism industry as well. Joined once again by Benjamin Crook… clinical nurse educator in emergency and creator of the ED jam medical podcast, we're going to run through some of the things you need to know… about shark attack first aid…ED jam podcast:https://open.spotify.com/show/6YIYojOqLWI5twHHajZrsU?si=ec6492d85ed9428eVideos Tac MED video on how to apply a tourniquet https://www.youtube.com/shorts/zvx6LGR98dAhttps://www.youtube.com/shorts/zvx6LGR98dA First aid kits https://tacmedaustralia.com.au/products/operator-ifak-kit?variant=43597288776&country=AU¤cy=AUD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gad_campaignid=16926729736&gbraid=0AAAAADjEEaayH9SM_nYsensJeih3ScQ6V&gclid=CjwKCAjw24vBBhABEiwANFG7y_dEKWiR_Yd9dsPMYgDe_grPMIax4gXWVtYtkSBoQ57J1-vxHoynlBoCWxQQAvD_BwESupport the show

In today’s very special episode, I sit down with my partner, Tanner, to discuss how his attempt to save sharks and do the right thing nearly landed him in jail. We recorded this episode a week after learning that Tanner had been pardoned by President Donald Trump.In August 2020, Tanner Mansell, a crew member on a shark-diving charter boat off the coast of Jupiter, Florida, came across a longline fishing setup approximately three miles offshore. Believing it to be part of an illegal operation, Tanner and the boat’s captain, John Moore, freed 19 sharks and a giant grouper that had been caught on the line. They reported the incident to state wildlife officials and brought the fishing gear back to shore.Unbeknownst to them, the longline belonged to a licensed fisherman. As a result, federal prosecutors charged Mansell and Moore with theft of property within special maritime jurisdiction—a federal felony.Book a trip with Tannerhttps://www.tannerunderwater.comAnd follow his social media, @tannerunderwaterSupport the show

In this episode, we dive into the ongoing debate about whether shark populations are truly booming or if this claim is based on misconceptions. With growing concerns from fishermen, particularly in the U.S. and viral discussions on social media, we explore whether sharks are increasing in numbers or simply recovering to historical baseline levels. Joining the conversation is marine ecologist and investigative journalist Spencer Roberts, who provides insights into the factors fuelling the "shark overpopulation" hysteria.

This episode is ideal for anyone pursuing a career in marine biology as we sit down with Richard Fitzpatrick, an Australian marine biologist, award-winning cinematographer, and shark expert. Based in Queensland, he has spent decades studying marine life, particularly sharks and other large predators, contributing to scientific research and conservation efforts. Fitzpatrick is well known for his work with National Geographic, the BBC, and Discovery Channel, where his stunning underwater cinematography has brought the ocean’s most fascinating creatures to global audiences. As a key researcher at the Australian Institute of Marine Science, he’s also played a crucial role in tagging and tracking sharks to better understand their behaviour and migration patterns. His passion for marine conservation and storytelling has made him a leading voice in ocean preservation.Check out on instagram @biopixeloceansWeb is biopixeloceans.orgShark Tracking website: Biotracker.orgRead the book: https://www.amazon.com/Shark-Tracker-Confessions-Underwater-Cameraman/dp/1742234933 * Butler, F., Holcomb, J.
