Are you interested in learning about marine life, going fishing, or exploring the underwater world with a mask and snorkel? If so, this is the camp for you! This local education opportunity for budding marine scientists will be happening this summer at Camp Timpoochee in Niceville, FL. The camps enable participants to explore the marine and aquatic ecosystems of Northwest Florida; especially that of the Choctawhatchee Bay. Campers get to experience Florida’s marine environment through fishing, boating snorkeling, games, STEM (science, technology, engineering & math) activities and other outdoor adventures. University of Florida Sea Grant Marine Agents and State 4-H Staff partner to provide hands-on activities exploring and understanding the coastal environment.

Florida Sea Grant has a long history of supporting environmental education for youth and adults to help them become better stewards of the coastal zone. This is accomplished by providing awareness of how our actions affect the health of our watersheds, oceans and coasts and marine camp is a great opportunity for sharing that information. Many of the Sea Grant youth activities use curriculum developed by the national Sea Grant program and geared toward increasing student competency in math, science, chemistry and biology. The curriculum is fun and interesting!
Marine Camp is open to 4-H members and non 4-H members between the ages of 8-13 (Junior Camp) and, new this year, ages 14-17 (Senior Camp). There will be two Junior Camps in 2018. The July 23-27 camp is full, but there are still openings for the June 25-29 session. The cost for Junior Marine Camp is $275.00 for the week. A more intensive Senior Marine Camp has been scheduled for July 16-20. This camp will contain a community service component and costs $300 for the week.
If Marine Camp sounds interesting to someone you know, visit the Camp Timpoochee website at http://florida4h.org/camps_/specialty-camps/marine/ for the 2018 dates and registration instructions. A daily snack from the canteen and a summer camp T-shirt are included in the camp fees, along with three nutritious meals per day prepared on site by our certified food safety staff. All cabins are air-conditioned. So many surprises await at marine camp, come join the fun.

Spring has sprung and it is time to get outside and explore this great Florida Panhandle area. In neighboring Santa Rosa County, a terrific destination for a variety of outdoor activities is Blackwater River State Park. Visitors can canoe, kayak, tube, fish and swim the river. Hikers can enjoy trails through nearly 600 acres of undisturbed natural communities. Bring a picnic and hang out at one of several pavilions or white sand beaches that dot the river (restroom facilities available). Near the pavilions, stop and see one of the largest and oldest Atlantic white cedars, recognized as a Florida Champion tree in 1982. The park also offers 30 campsites for tents and RVs. Park entry is $4.00 per car, payable at the ranger station or via the honor system (bring exact change, please).
The Blackwater River is considered one of the purest and pristine sand-bottom rivers in the world. The water is tea-colored from the tannins and organic matter that color the water as it weaves through the predominantly pine forest. The river is shallow with a beautiful white sandy bottom, a nice feature for those tubing or paddling the trail. The river flows for over 50 miles and is designated as a Florida canoe trail. Multiple small sand beach areas line the river and provide plenty of space to hang out, picnic, or throw a Frisbee. Blackwater eventually flows into Pensacola Bay and the Gulf of Mexico bringing high quality freshwater into this important estuary.
A favorite trail in the Park is the Chain of Lakes Nature Trail. Parking for this 1.75 mile loop trail is at South Bridge on Deaton Bridge Road. The trail head is well marked and has a boardwalk that leads into the floodplain forest. The trail winds through a chain of shallow oxbow lakes and swamp that dot the former route of the river. If you are lucky and it is a clear, blue-sky day, you may see a beautiful rainbow effect as the sun hits the water. We call this the pastel swamp rainbow effect. This is a result of the natural oils from the cypress cones settling on the surface of the water and associated trapped pollen.
The trail then turns to sneak through the sandhill community in the park with giant longleaf pines, wiregrass and turkey oak. Evidence of prescribed burning shows management efforts to maintain the forest. Cinnamon ferns, bamboo and other natives appear in pockets along the trail. The trail in this section is blanketed with a mosaic of exposed root systems, so be careful as you step. Finally, pack some bug spray and a water bottle for this fun hike.

Aquaponic Napa cabbage
There is growing interest in hobby-scale farming techniques. In response to this need, UF/IFAS Walton County Extension Office established a hobby farm featuring a variety of low-input food production options. The farm is a cooperative venture drawing on expertise of the Horticulture, Aquaculture/Marine Science, 4-H, and Agriculture programs. The farm is on a relatively small, tenth acre, plot behind the County Extension Office where staff and volunteers have installed aquaponics and hydroponics systems, honeybee boxes, a chicken coop as part of the 4-H Chick Chain Program, herb garden, raised vegetable bed system, sustainable citrus grove, muscadine grape trellis, shiitake mushroom structure, and blueberry orchard.

Aquaponic Swiss chard
The aquaponics demonstration system was constructed in 2017 using materials purchased at local stores, Tractor Supply Company and Lowes, or on Amazon.com. The system has a 300 gallon Rubbermaid fish tank that gravity feeds into a 20 gallon plastic garbage can with lid stuffed with bird netting for solids removal and biofiltration. The water then feeds into two 2 ft. x 8 ft. feed troughs with approximately 2 square yards of floating Styrofoam grow beds. Finally the water drains into a 100-gallon sump where it is pumped back into the fish tank. A small air pump provides supplemental air to the fish tank and a small water heater helped maintain temperatures during the winter.

Aquaponic red lettuce
The fish tank is stocked with 18 catfish, originally 4-5 inches, now approximately 10-12 inches, and pushing a half-pound each. The system produced two crops of red and romaine lettuce during the last half of 2017 and is currently planted with romaine and red lettuce, Swiss chard and Napa cabbage. Lettuce is harvested out of the system every five to six weeks, while Swiss chard and Napa cabbage a take longer to reach harvest size.

There is a lot of aquaponics information available on-line. Academic institutions and other research-based organizations are the best places to look for information. The University of Florida has a comprehensive factsheet entitled “A Practical Guide for Aquaponics as an Alternative Enterprise” available at http://edis.ifas.ufl.edu/hs1252. Also recommended is the Food and Agriculture Organization “Small-scale Aquaponic Food Production” manual available at http://www.fao.org/3/a-i4021e.pd.
Aquaponic seminars or webinars are conducted upon request and provide introductory information on a variety of system designs and stocking options. Over 400 visitors have seen the aquaponics and other hobby-scale gardening demonstration plots over the past year, gaining knowledge and acquiring skills to use in their own gardens. If you are interested in a signing up for the aquaponics email listserv, participating in a tour, having a personal consultation or attending a workshop, please contact Laura Tiu, lgtiu@ufl.edu.

Scallops and shrimp over grits.
I have been involved in the aquaculture industry since the late 1980’s when I got my first job out of college on a tropical fish farm in Plant City, FL. As you can imagine, the industry has changed a lot since then. When folks find out I have worked in aquaculture, the same question seems to arise: “Is farm-raised fish safe to eat as wild caught?” I would like to say that I don’t understand where this question comes from, but over the years I have seen a bewildering number of mass media headlines touting misinformation about farm-raised fish and not enough touting the benefits. In fact, I saw a post this week on Facebook actually claiming that tilapia have no skin or bones and cannot be found in the wild, both not true. It is no wonder people are so confused. Many of the claims made are not research-based and a quick review of the scientific literature will disprove the statements, but who has time for that?
Aquaculture currently supplies over fifty percent of all seafood consumed and will expand in the future due to a limit on the amount of wild fish that can be sustainably harvested, and increasing demand by a growing population. Sustainable, responsible aquaculture is needed to fill that gap. Fish are farmed using a variety of production methods including ponds, raceways, recirculating land-based systems and in ocean net pens. Each one of these fish species and production methods comes with pros and cons, similar to the production of livestock and fruits and vegetables. Each species can be evaluated based on its environmental impact, production method and even country of origin.
The American Heart Foundation recommends eating fish (particularly fatty fish rich in Omega-3s) two times per week. We currently only consume about half of that. This recommendation includes a variety of farm-raised and wild-caught fish. Both are crucial to meet current and future demand for seafood and omega-3 fatty acids. A common misconception is that farmed fish is not as healthy or nutritional valuable as wild caught fish although this claim has been largely disproven. One recent paper (Trushenski et al, 2017) compared the nutritional values of wild-caught and farmed bluegill, largemouth Bass and hybrid striped bass and concluded that the farmed fish provided more long-chain polyunsaturated fatty acids (LC-PUFAs) per portion that wild fish, however both are excellent sources of high quality protein and nutrients.
With the Lenten season upon us, a time of a traditional increase in seafood consumption, what is an easy way to choose wild and farm-raised seafood? One website and smartphone app that I find easy to use is Seafood Watch (www.seafoodwatch.org). Seafood Watch uses an extensive evaluation system using research and a panel of experts to label seafood products as green (best choice), yellow (good alternative) and red (avoid) depending on the variety’s sustainability.
With this information and a little bit of homework, I hope you come to the same conclusion that I have. Both farm-raised fish and wild-caught fish are delicious, nutritious and great additions to your diet.

The lodge at Camp Helen State Park was the perfect backdrop for the Coastal Dune Lake Seminar Series Water School. Brandy Foley of the Choctawhatchee Basin Alliance shares her paleolimnology research work on the lakes.
On a beautiful October day, 35 people gathered at the Camp Helen State Park lodge to share information about the rare Coastal Dune Lakes (CDLs) that line the coast of Walton and Bay Counties. Organized by the University of Florida Extension Programs in Bay and Walton counties, the Water School included a morning seminar series featuring speakers from various groups that work together to support the lakes. Laura Tiu, Sea Grant Agent for Walton and Okaloosa counties started off the day giving a broad overview of the history and ecology of the lakes. Brandy Foley of the Choctawhatchee Basin Alliance shared her research on the paleolimnology, or study of the lake sediments over time, of two coastal dune lakes. Clayton Iron Wolf, a ranger at Camp Helen, gave a summary of the importance of Lake Powell and its benefit to the park. Jeff Talbert of the Atlanta Botanical Garden thrilled attendees with his pictures and research on the Deer Lake State Park restoration project. Norm Capra, who wears many hats, including that of the Lake Powell Community Alliance and Friends of Camp Helen State Park, shared the work they have done promoting conservation of shorebirds there. Dr. Dana Stephens, Director of the Mattie Kelly Environmental Institute at Northwest Florida State College shared analyses of many years of water chemistry and quality data collected on the lakes. Melinda Gates, Environmental Specialist for Walton County, wrapped up with a presentation on the efforts to protect and preserve the lakes.
The attendees seemed pleased with the event with one hundred percent of attendees rating the quality of information presented, usefulness of information, speakers’ knowledge, overall value of the program, and quality of location as good or excellent. The seminar helped attendees identify important roles of the CDLs in the ecosystem and understand why it is important to protect them. Several participants plan to make behavior changes based in the workshop including: joining or volunteering with Choctawhatchee Basin Alliance, Audubon, Sierra Club or Lake Watch Volunteers; sharing the information; living minimally; and engaging in activism. The seminar was followed by a kayak tour lead by Scott Jackson, Bay County Sea Grant Agent, to the outflow of Lake Powell and a visit to a faux sea turtle nest demonstration by Florida Fish and Wildlife Commission. This Water School was part of a regional series offered by UF/IFAS Extension. For more information on future schools, please subscribe to our Panhandle Outdoors Newsletter.
