Strike a pose with Shark Stanley for shark conservation

January 3, 2013 by Leave a Comment

Surely you’ve taken pictures with Flat Stanley, a tool used to advance children’s literacy – But, did you know that you can now take a shark on your adventures? Grab a Shark Stanley printout and show your support for shark conservation by participating in this initiative of the Shark Defenders. Help them reach their goal of collecting at least 5,000 photos! It’s important to gather these photos in time for the upcoming Convention on International Trade in Endangered Species (CITES) meeting in March. Check out all the places Shark Stanley has been on the Instagram and Facebook pages!

Why is shark conservation important?

Sharks are in peril and overexploited due in major part to a voracious demand for shark fins, especially in Asian markets. Shark finning is the removal and retention of shark fins and  discarding the body at sea (The animal is often alive when tossed back into the water!). The Pew Environment Group estimates that “Up to 73 million sharks are killed every year to primarily support the global shark fin industry”. The underlying problem is that sharks grow slow, mature late, and produce few young over their long lifetime – meaning their populations recover slowly once depleted. Depleted populations affect the health of the entire ocean ecosystem. Here are some examples on how it’s all connected:

  • Sharks help maintain healthy fish stocks because they prey on vulnerable sick, diseased, or old animals – thereby, preventing disease or sickness from spreading.
  • Sharks have the ability to ensure we always have vital seagrass beds by controlling their prey, dugongs and green sea turtles – which forage in these beds. Healthy seagrass beds are essential for maintaining good water quality in our estuaries.
  • Sharks are the #1 draw for many divers providing a booming tourism industry to remote places that might not otherwise have a good economy.

A naturalist’s must-see destination: Cape May County (and, the rest of south Jersey)

April 20, 2012 by 2 Comments

Earlier this year I was happy to see that the federal government had awarded New Jersey a $1 million grant to protect the ecologically sensitive wetlands in Cape May County (“Where Nature Smiles for 30 Miles” and where my hometown is located). The New Jersey Department of Environmental Protection (DEP) will use the money to purchase 140 acres to add to the existing 17,000-acre Cape May Wetlands Wildlife Management Area. These wetlands are not only where I fell in love with the natural world, but are also home to many species of migratory birds and act as a nursery for many commercially important species of fish that spawn in the estuaries.

So with a combination of my pride in the DEP’s award and my feelings that an ‘ode to home’ in the Where We Live series is long overdue, I decided to take the time to compile a list of “10 unique and interesting natural history or maritime features of south Jersey”. I am sure there are plenty more out there, so please feel free to comment below or send me an email at info@beachchairscientist.com if you have any additional comments or questions.

1. South Jersey sits to the east of the Delaware Bay. The Delaware Bay boasts the second-highest concentration of shorebirds in North America (second to Quivira, Kansas which is mid-point in the United States). The Bay is mid-point in travel for many birds that travel from the warm weather of South America up to the Arctic. The Bay is also a perfect wintering habitat for many species of songbirds and waterfowl.

2. The world’s largest population of Atlantic horseshoe crabs (Limulus polyphemus) spawn in Delaware Bay.

3. At the entrance of the Delaware Bay is the Cape May Lighthouse, built in 1859, which documents the beginning of Cape May County’s nautical history. There is also the Hereford Inlet Lighthouse, built in 1874, on the Atlantic Ocean side of the Cape May County peninsula in North Wildwood. Speaking of Cape May, the famous Cape May diamonds people have been looking for since the 1880’s are actually quartz crystals that wash up as smooth rock.

4. At 3800 Boardwalk Mall in Wildwood you can see the 43rd Wyland Whaling Wall, “Humpbacks off the Jersey Coast” (pictured right). Wyland is known as “one of America’s most unique creative influences, and a leading advocate for marine resource conservation”.

5. The A.J. Meerwald, New Jersey’s official Tall Ship, began life as a sailing schooner built for oystering,  but was commandeered during World War II to serve as a fireboat on the Delaware Bay.

6. The Stone Harbor Point is one of the few parcels of New Jersey’s coast that has not been stabilized (86% of the shoreline has been stabilized) leaving a remarkable wide open space that has been shaped (and reshaped) by waves and tides for centuries. It also has one of the last thickets of bayberry left on New Jersey’s coast.

7. The Marine Mammal Stranding Center in Brigantine has the impressive achievement of responding to over 3,900 strandings of whales, dolphins, seals, and sea turtles (all, of course, done with a permit and authorization from the state and federal governments).

8. In south Jersey you’ll also find the Pine Barrens, a distinctive natural area spanning over  1 million acres of the Outer Coastal Plain (pictured left) in southern and central New Jersey. Dr. Witmer Stone, an early New Jersey natural scientist described the area as “always sandy and thickly covered with more or less scrubby vegetation, interspersed with swamps and infested by hordes of mosquitoes”. This area is particularly prone to fires and some species, such as the rare pygmy Pitch Pine, have become adapted to the fires and count on the fires to reproduce. The sandy soil of the Pine Barrens is sometimes referred to as sugar sand.

9. Blueberries were officially named the state fruit in 2004. New Jersey produces the second most blueberries in the world (Maine is first). Hammonton is considered the “Blueberry Capital of the World”.

10. After the federal government designated the Outer Coastal Plain as an American Vinticultureal Area, south Jersey started up on the wine trend! Now south Jersey has more than 20 fully functioning wineries and vineyards.

As Jacques Cousteau said, “People protect what they love“. I am sure you can tell from this blog that I do love the ocean. This love no doubt came from growing up in south Jersey and spending time everyday at the beach or the nearby Bay.  Here’s a poem I wrote (almost 12 years ago) about the area. I hope you’re inspired to learn about the natural history of your own area – especially on this upcoming Earth Day weekend.

Cheers!

‘Wicked Tuna’ is food for thought

March 31, 2012 by 2 Comments

Tomorrow the National Geographic Channel (of which approximately over 50% is owned by NewsCorp, a Murdoch Company) is debuting the television show Wicked Tuna. The show is intriguing because the species itself is remarkable.

Atlantic bluefin tuna (Thunnus thynnus) can swim up to 40 miles per hour and can dive up to 3,000 feet. Their body is so remarkably streamlined for efficiently swimming through the ocean that Pentagon-funded scientists have studied the species as a model for Navy torpedoes. They’re also known to travel far and wide (actually, across entire oceans over their lifetime). This causes some challenges when coming together to manage the species.

The dilemma I have in deciding to watch the show is that NatGeo may be glorifying the bluefin tuna as a species of consumption so that people start ordering it more. But, folks need to understand the repercussions and ask one more question, “Is this bluefin tuna caught in the U.S.?”

As I mentioned, there are some challenges with managing a species that spans globe. Bluefin tuna are an internationally managed species, guided by the intergovernmental body the International Commission on Conservation of Atlantic Tunas (ICCAT). Within management plans of the ICCAT, it is irrefutable that the U.S. bluefin fishery is the most sustainably managed in the world. The bluefin tuna caught in Maine, New Hampshire, and Massachusetts is predominantly hand gear (rod and reel or harpoon). This fishery is well regulated and responsible. There is also bluefin tuna caught as bycatch from the longline fisheries targeting other types of tuna. To reduce bycatch, fisheries are now required to use circle hook and weak hooks to reduce the bluefin tuna bycatch, as well as other nontarget species (e.g., sea turtles). The species is slow to mature and catching young bluefin tuna reduces the chance they’ll have the opportunity to reproduce. That is why it is so negligent to eat the bluefin tuna from the poorly regulated European fishery. Many of the bluefin caught there are with purse seines or longlines. In fact, since industrial fishing began in the Mediterranean it is estimated that over 80 percent of bluefin stocks have been fished out.

It’s no help that there is extreme demand for this type of fishing pressure as sushi chefs will pay gobs for the fish. The ‘Wicked Tuna” fishermen can get up to $20,000 for each fish. In January 2012, a Tokyo restaurant paid $736,000 for a bluefin tuna at auction (there’s the ‘first fish phenomenon’ which can bring a lot of publicity to a restaurant for paying a high amount for the first fish). Click on https://www.altitude-sports.com/collections/footwear-men-hiking-boots to find the best quality camping equipment for you.

The Monterey Bay Seafood Guide lists bluefin tuna as a species to avoid. The Center for Biological Diversity encourages the public to boycott any restaurants serving bluefin tuna. Greenpeace has even stated that, “The world needs to see a ban on bluefin tuna fishing until stocks recover”. National Geographic claims this show’s scope includes a “solid conservation message about what’s been going on with the bluefin”. So, if you must ask for ‘Wicked Tuna’, make sure it’s at least from the U.S. Certainly, food for thought.

EE, Ocean, & Water Conservation Infographics

It’s no secret that a picture speaks a thousands words. But, when you couple words and pictures (with numbers, arrows, charts, etc.) you get quite an impact. If you’re a regular reader of the BCS blog you already know I’m fond of infographics. So I decided to pull together the ones found on BCS, as well as other places. You’ll see this list follows the general themes found on BCS: marine science, water/ocean conservation, as well as connecting with nature. I hope you enjoy browsing and a special thanks to all the organizations that have produced these powerful resources. To check out the collective visual of most of these infographics please check out my EE, Ocean, & Water Conservation Infographics Pinterest board. Please email info@beachchairscientist.com or let me know on Twitter  (@bcsanswers) if you have another one that could be added to the list.

Crocodile Hunter’s dad working to save dugongs

January 1, 2012 by 1 Comment

Dugongs, a relative of manatees, are found off the coast of Africa and Australia. Steve Irwin’s dad, Bob, is on a mission for an “immediate moratorium on the hunting of endangered dugongs and sea turtles around the Australian coastline by Indigenous hunters.” Politicians have also been calling for the end to the hunting of dugongs and turtles after the 2004 research of Helene Marsh made a serious impact. All of their efforts, coupled with new findings that dugongs spend more time underwater than previously thought, has led Marsh to be more optimistic about the future of the endangered dugong (Although with the recent depletion of sea grass there is still an uphill battle).

4 fun facts about dugongs:

1. Dugongs are very similar in features to manatees but have a fluked tail.
2. In a group, dugongs are called a herd.
3. A common ‘common name’ for the dugong is the ‘sea cow’ since they enjoy grazing on sea grass.
4. All dugongs grow tusks but they only break the skin and are visible in mature males.

13 apps for your day at the beach

August 17, 2011 by 2 Comments

It’s time to get the most out of that last trip to the beach!

Whether you’re ready for a day out on the boat, lounging, beachcombing, catching some waves, or preparing a feast there is an app to get you more involved in your marine environment. Apps are not only a great way to learn something new on the fly but can be a useful tool for engaging one another in settings where you may not have common ground. (OK, at the very least apps settle many ‘discussions’.)

Here is a list of useful and rather attractive apps that can connect you to your inner marine biologist.

AUDUBON FIELD GUIDES: Audubon Fishes of the Caribbean and the Gulf of Mexico and Audubon Fishes – A Guide to North American Fishes include photos, geographic ranges, and concise yet detailed descriptions of appearances. Coming soon is the field guide for the Mid-Atlantic shoreline. ($9.99)

OCEANOGRAPHY STUDY GUIDE: If you are into fun oceanography trivia and want to learn more about the geography of the sea than download this app. It isn’t an endless list of “did you know?” facts but rather a large range of topics with well written articles for the serious beach chair scientist. ($4.99)

OFFICIAL APP OF ISSF: The International Seafood Sustainability Foundation (ISSF) was founded in 2008 when leaders of industry, scientists and environmental champions voiced concern over the future of tuna fisheries. This app provides a glossary of terms, videos, and a list of the status of stocks. (Free)

SEA TURTLE APP: This app was created by the Sea Turtle Conservancy and allows you to follow read the latest on sea turtle news but much more exciting you can track the global migration of different sea turtles with interactive satellite tracking maps! (Free)

Enough sitting around – it’s time to get out there and do something:

MOBILE APP FOR IGFA: The International Game Fishing Association created an app for weigh station locations, angler rules and regulations, customizable quests, and advice for trip planning. What more does a sport fisherman need?

MARINE DEBRIS TRACKER APP: This collaboration is brought to you by the Southeast Atlantic Marine Debris Initiative. The reporting of where you find marine debris can help to focus and prioritize federal efforts. The app uses GPS and allows you minimal work of sorting through lists of common marine debris. (Free)

CRAB APP: This app is an offshoot from the marine wild lab and allows you to collect horseshoe crab species data that will be used in scientific research. Horseshoe crabs are of enormous importance to 1) the drug industry due to their blood, 2) to fisheries for bait, and 3) to migratory shorebirds for its eggs.  (Free)

TIDE GRAPH: I found out that there are many, many apps out there to help you monitor the tides. Tide Graph will work for both coasts in the US and provides graphs to help you see how the tide changes over the day and the month. ($1.99)

If you are preparing a feast or gorging on some dockside seafood:

SEAFOOD WATCH: For years the Monterey Bay Aquarium has produced adorable pocket-sized regional cheat sheets so you can get a quick overview of what species are considered over fished or not in your neck of the woods. They continue to produce this application for your iPhone and use GPS tracking to discover where you are so you can get the most relevant information. (Free)

PROJECT FISHMAP: Monterey Bay Aquarium also gets you more involved by asking you to submit information when you find a restaurant or market that advocates sustainable seafood. As the map grows you can see what spots you’ve not uncovered in your neighborhood. (Free)

FISHPHONE APP: With one quick text (example: “fish salmon”) to 30644 Blue Ocean Institute will fed you intel on your species of choice. For instance, they’ll rank the sustainability and toxicity levels and send an overview of its conservation status. (Free)

SAFE SEAFOOD: This app takes information from ten different seafood rankings (including Monterey Bay Aquarium and the Environmental Defense Fund) to create its list. The app outlines choices in an easy to review “best to worst” list. I particularly like that fish with multiple different market names are listed by each of common name too. ($0.99, but 10% of the proceeds go to EDF)

I am certain I missed many wonderful apps. Please do not hesitate to email at info@beachchairscientist.com to share!

Added October 27, 2011: An app for water quality and to get the most up-to-date grade for your beach presented by Heal the Bay in California.

Where is the coral triangle?

August 16, 2011 by Leave a Comment

After some research I scored a wonderful description of where the world’s most ecologically diverse  marine ecosystem lies. Spanning over six countries this 6 million kilometers squared coral triangle is significant because it is home to six of the seven species of sea turtles. This infographic, produced by World Wildlife Fund, gives a rundown of the protection status of each the sea turtle species as well as a wealth of other great information. For instance, did you know …

… 3000 leatherback sea turtles nested along the coast of Terengganu, Malaysia in 1960? In 2000, according to data from Dr. Chen Eng Heng with the Department of Fisheries in Malaysia, there were none.

… 90% of sea turtle hatchlings never make it to their first birthday.

Take a closer look at the infographic to learn more. Lastly, don’t forget May 23rd is International Turtle Day!

Did you know that almost half the world’s turtle species are considered threatened?

Founded in 1990, the American Tortoise Rescue sponsors May 23rd each year to “increase respect and knowledge for the world’s oldest creatures”.

Here is a link where you can learn more about sea turtles. Please take some time to share your knowledge about these ancient creatures with your friends and family!

What is bycatch?

January 1, 2011 by Leave a Comment

Bycatch is a term used to classify the incidental fish, mammals, birds, sea turtles or invertebrates that may be caught while targeting other species in a fishery. One of the biggest victims of these unintentional catches are the black-footed albatross. They frequently swallow bait attached to the lines of long-line fishing boats. At least 300,000 sea birds are killed by long line fishing each year.

Where have all the horseshoe crabs gone?

August 31, 2010 by 1 Comment

If you’ve kept on eye on the sandy shores of the Atlantic Ocean or eastern Gulf of Mexico over the past twenty years you’ve noticed a significant decline in the number of horseshoe crabs, Limulus polyphemus, covering the beach. As a marine educator and naturalist in my past life, I always said the decline was due to over harvesting for bait and pharmaceutical needs. This is only half the reason. Recently scientists also noted that climate change, with the sea level rise and temperature fluctuation, may be a cause of the decline.

Tim King, a scientist with the United States Geological  Survey, thinks that what happened during the Ice Age could happen again. With climate change comes a loss of habitat and a loss of diversity. These issues could have severe implications, not only for horseshoe crabs, but also for species that rely on them for sustenance. For instance, along the Delaware Bay the red knot eats the horseshoe crabs eggs at the midpoint of their migration. In the Chesapeake Bay, loggerhead sea turtles are struggling to find one of their favorite food sources, horseshoe crabs, and are retreating elsewhere to find food. Now that the link of a decline in the horseshoe crab population and climate change has been made fisheries managers can take this into consideration.
