Laura Tiu, UF/IFAS Marine Science Agent
Laura Tiu is the Marine Science Sea Grant Agent with the University of Florida Extension Service in Okaloosa and Walton Counties. Raised in Sioux City, Iowa, she left the cornfields of the Midwest to pursue her dream of becoming a marine biologist, following in the footsteps of the infamous Jacques Cousteau. Living in the Philippines for four years was the educational experience of a lifetime, with adventures to the tops of mountains to the depths of the sea. She was fortunate to work on the very first marine preserve in the Philippines on Apo Island, which has since evolved into a scuba diver paradise.
Coming back stateside, her first professional job was as a fish breeder on a tropical fish farm in Plant City, Florida. This is where her passion for aquaculture was born. After a brief stint at Mote Marine Laboratory in Sarasota, Florida, Laura left for Mississippi State University where she earned a Master of Science degree in Wildlife Ecology, focusing on fisheries and aquaculture. Her thesis explored the impact of largemouth bass maternal size on survival of fry. Not one to follow a straight path, Laura joined the staff at Kentucky State University Aquaculture Program where she spent the next eight years doing fish nutrition work on multiple species including catfish, trout, hybrid striped bass, hybrid bluegill, paddlefish and freshwater prawn. This experience gave her a great appreciation and understanding how research can help grow the burgeoning aquaculture industry.
With a desire to do Extension work and a goal to continue her graduate work, Laura spent the next 18 years at The Ohio State University where she earned her Ph.D. in Extension Education while serving as Director of the Aquaculture Extension Program. She was responsible for supporting the development of a sustainable aquaculture industry in Ohio and throughout the Midwest. During her tenure, the number of aquaculture operations in Ohio increased from 30 to over 200, with many of the startups graduating from her Aquaculture Boot Camp program.

Circling back to her passion for marine science, Laura joined the University of Florida Sea Grant program in 2015. Her current programs include natural resource and environmental education and aquaculture. She provides programming in natural resource stewardship through the Florida Master Naturalist Program and Panhandle Outdoor Live, which offers interpretive, and now virtual, environmental education. She loves to educate clients about the awesome natural resources in the Panhandle including the farm ponds, numerous springs, creeks, rivers, estuaries, beaches, offshore reefs, and the coastal dune lakes of Walton County. She spends a good part of her summer helping with the 4-H marine camps at Camp Timpoochee in Niceville, FL. Her aquaculture passion remains strong through her work with a growing aquaponics community in the state.
Laura lives with her retired husband in DeFuniak Springs, FL where they enjoy fishing, kayaking, swimming and exploring the great natural resource areas in the Panhandle. She loves to play tour guide when her two grown sons, family and friends come to visit. “I just love to show off the natural beauty of our area and help others better understand what they can do to help protect our environment.”

Fall is such a spectacular time in the Florida Panhandle. The crowds are gone and the thermometer rests at a pleasant 50-70-something degrees. It is the perfect time of year to enjoy our amazing environment. Nature has a magical way of boosting our energy levels and immune systems and improving mood and focus. We can all use a heaping helping of that right now.
So where do you start? Here are some ideas.
Take in a sunrise or sunset. The beach is often one of the best places to do this, but anywhere will do. Last weekend, I was at the Okaloosa Island Boardwalk and Pier and the sunset was magnificent. While there, take a walk along the beach, let the cool sand squish between your toes and discover what might be hiding in the wrack. The wrack is that line of seaweed deposited after high tide. Upon close inspection, it contains many treasures including seagrasses, sponges, shells, worm tubes, small crabs and other oddities.
Take a nature hike. I love the nature trails at our local state and national parks, Henderson Beach, Topsail, Blackwater and Grayton Beach State Parks all have great trails. You may see some wildflowers this time of year. Look for animal tracks and resident birds. You may also see some monarch butterflies on the saltbush, resting as they continue their migration to Mexico.
Check out the springs. Morrison Springs and Ponce de Leon Springs in the state park in Walton County are an easy drive. Sit and enjoy the beauty and peaceful nature that surrounds the springs. Dip your toes in the cool water for a refreshing tingle or jump right in if you dare.
If you have a kayak, canoe or paddle board, it’s a great time to be on the water. Look for migrating shorebirds, schools of fish or pods of dolphins. Did you know we have over 60 dolphins that call the Destin area home year-round? You can often find them cruising in the Choctawhatchee Bay, or hop aboard one of our local dolphin cruises to catch a better glimpse.
Finally, our local fresh seafood is available year-round. Plan a picnic with some fresh shrimp or smoked mullet dip. Seafood offers many of the same benefits as time in nature, so double up on all the goodness that fall has to offer. Get outside and get happy!

When one thinks of the Emerald Coast, visions of sparkling water, baby-powder beaches, rental houses and high-rises interwoven with seafood and pizza restaurants appear. The coast is dotted with fishing boats, pirate ships and dolphin cruises and the beaches are littered with people. But it is what glides under the water that some people are curious about. “Are there sharks in the water here?” is a question I often get from locals and tourists alike. The answer is yes, sharks call saltwater home.
Sharks evoke a variety of emotions in people. Some folks are fascinated and list shark fishing and diving with a shark on their bucket lists. Others are terrified, convinced that sharks only exist to hunt them and bite them while they take a swim. Unfortunately for the sharks, their appearance plays into this later fear, with sharp teeth, unblinking eyes and sleek bodies. The reality is that most sharks only grow up to three feet in length and eat small shrimp, crabs and shrimp, not humans. But it is true that bull, tiger and great white sharks are all large species that have been known to attack humans.
Of the 540 different species of sharks in the world, there are about twelve that call the Emerald Coast home including Atlantic sharpnose, bonnet head, blacktip, bull, dusky, great white, hammerhead, nurse, mako, sand, spinner, and tiger. They don’t all stick around all year, with some migrating south in the winter, while others migrate north.
Sharks use their seven senses to interpret their environment: smell, sight, sound, pressure, touch, electroreception, and taste. Most shark attacks occur when a human is mistakenly identified as prey. There are some easy measures you can take to reduce the risk.
- Swim with others, this may intimidate sharks and allows someone to go for help if a bite occurs.
- Remove jewelry as it can look like an attractive shiny fish underwater.
- Don’t swim where folks are fishing as bait in the water may attract sharks.
- Pay attention to any schools of baitfish in the area that may be attracting sharks.
- Do not swim at dusk or dawn when visibility may be poor.
- Learn how to identify various shark species
Remember, shark attacks on humans are rare. Reports of stepping on stingrays, jellyfish stings, lightning, dangerous surf conditions and car accidents greatly outnumber the number of shark attacks every year.

“An Equal Opportunity Institution”
by Laura Tiu | Jul 3, 2020
Fishing is big business in Florida, contributing billions of dollars each year to the state’s economy. Fishing guides are an important part of the fishing industry. Guides provide locals and tourists alike with authentic Florida fishing experiences and memories that last a lifetime. Fishing guides are role models that can teach ethical angling through their onboard behaviors.
The Florida Friendly Fishing Guides Certification was developed by the University of Florida IFAS Extension, Florida Sea Grant, and the Florida Fish and Wildlife Conservation Commission with input from fishing guides. It is a voluntary certification program and involves no regulatory component. The target audience is flats guides, charter boat captains, and head-boat captains and crew. Recreational fishers are welcome to take the course, too.
What will I learn?
The Florida Sea Grant Florida Friendly Fishing Guide online course teaches best practices for catch and release fishing. Each lesson plan focuses on a different aspect of ethical angling. There are modules on seafood safety, federal and state fisheries management, onboard waste management, and how to teach your customers about the environment.
One environmental impact of fishing is what we call discard mortality. This is when a caught fish is released but does not survive. You will learn how to increase fish survival, how to identify barotrauma, and how to use descending and venting tools.
Starting July 15, 2020, a descending device will be required for head-boats, charter boats, commercial, and recreational vessels fishing for reef fish in federal waters of the Atlantic Ocean from North Carolina to Florida. The Florida Friendly Fishing Guide course will teach you how to identify barotrauma and select the right tool for sending fish back down to depth! Proper fish handling skills are important because up to 60% of caught fish are released.
The cost is $130 and the course takes about 4 hours to complete. Once you complete the course you receive a welcome package, public listing on the Florida Sea Grant website, and an optional social media promotion. For more information and registration go to https://www.flseagrant.org/florida-friendly-fishing-guide-certification/ or contact your local Florida Sea Grant agent, Laura Tiu, lgtiu@ufl.edu. Florida Friendly Fishing Guide Certification is a state-wide program for all saltwater fishing guides in Florida.

Have you ever been on a walk, passed a beautiful flowering bush, and wondered what it was? Well, wonder no more! You can become an expert naturalist by using an easy smartphone app, iNaturalist. With one easy download, you can connect with others to identify species and document their occurrence.
iNaturalist is a community of naturalists, citizen scientists and biologists working together to share observations of biodiversity and map the occurrence. Parents need to know that iNaturalist is an online community that allows users age 13 and older to share pictures and locations of the living things they see around them. While considered very safe, like any online network, teens should be cautious with sharing.
Getting started is easy. All you need to do is create an account at iNaturalist.org and download their free iNaturalist app to your smartphone (Android or iOS). You can then start making your own nature observations, upload them to iNaturalist where you can share your discoveries with others, and also let other iNaturalist users help identify what you have seen.
iNaturalist is a great way to connect with nature and generate scientifically valuable biodiversity data. You can use it for your own personal fulfillment, or as part of a group. You can even use the project feature which allows you to have a central page that displays all the observations made within a location, or all observations made by a group. Why not organize your neighbors, club, or friends and challenge them to post their observations?
