Big Fish Stories Getting Littler

Wednesday, February 05, 2014 - 11:38 AM

They came, they fished, then snap! They posed. Right in front of their Big Catch — and thereby hangs a tale.

For generations, tour boats have been collecting fishing enthusiasts in Key West, Fla.: taking them for a day of deep sea casting; providing them rods, bait, companionship; and then, when the day ends, there's a little wharf-side ceremony. Everyone is invited to take his biggest fish and hook it onto the "Hanging Board"; a judge compares catches, chooses a champion, and then the family that caught the biggest fish poses for a photograph. The one up above comes from 1958. Notice that the fish on the far left is bigger than the guy who, I assume, caught it; and their little girl is smaller than most of the "biggies" on the board. Those aren't little people. Those are big fish.

Here's another one from the year before — 1957. Again, the fish loom larger than the people. Check out the guy in the back, standing on the extreme right, next to an even bigger giant.

Charter companies have been taking these photos for at least 50 years now. In some cases, they've operated from the same dock, fished in the same waters and returned to the same Hanging Board for all that time — which is why, when a grad student working on her doctoral thesis found a thick stack of these photos in Key West's Monroe County Library, she got very excited. Lauren McClenachan figured she could use this parade of biggies to compare fish over time.

For example, here's a photo taken a decade after the previous shots — during the 1965-1979 period:

The fish in that one are still big, but no longer bigger than the fishermen. It's the same in this next one. Grandma and Grandpa are decidedly the biggest animals in the photo:

Let's keep going. This next photo was taken during the 1980-1985 period. It's a group shot, one of many. Everybody's displaying their biggest catches. Loren visited this wharf in 2007 and discovered, as she writes in her scientific paper, that these display boards "had not changed over time," which meant she could measure the board, and then (using the photos) measure the fish. Clearly, these fish are way smaller than the ones from the 1950s:

How much smaller? Adjusting for time of year, and after checking and measuring 1,275 different trophy fish, she found that in the 1950s, the biggest fish in the photos were typically over 6 feet — sometimes 6 feet 5 inches long. By the time we get to 2007, when Loren bought a ticket on a deep sea day cruise and snapped this picture ...

... the biggest fish were averaging only a foot, or maybe a little over. That's a staggering change. The biggest fish on display in 2007 was a shark, and sharks, Loren calculated, are now half the size they used to be in the '50s. As to weight, she figured the average prizewinner dropped from nearly 43.8 pounds to a measly 5 pounds — an 88 percent drop.

It's no big surprise, I suppose, that fish in the sea are getting smaller. The curious thing, though, is that people who pay 40 bucks to go fishing off Key West today have no sense of what it used to be like. Had Loren not found the fish photos, there would be no images, no comparative record of what used to be a routine catch.

In her paper, Loren says that the fishing charter tours are still very popular. The price of the tour hasn't dropped (adjusting for inflation), only the size of the fish. Looking at the photos, people now seem just as pleased to be champions as those "champs" back in the '50s, unaware that what's big now would have been thrown away then. Loren says she suspects that people just erase the past "and will continue to fish while marine ecosystems undergo extreme changes."

Change Blindness

Daniel Pauly, a professor at the University of British Columbia, has a way of describing these acts of creeping amnesia. He calls the condition "shifting baseline syndrome," and while he was talking about marine biologists' failure to see drastic changes in fish sizes over time, it's a bigger, deeper idea. When you're young, you look at the world and think what you see has been that way for a long time. When you're 5, everything feels "normal." When things change in your lifetime, you may regret what has changed, but for your children, born 30 years later into a more diminished world, what they see at 5 becomes their new "normal," and so, over time, "normal" is constantly being redefined to mean "less." And people who don't believe that the past was so different from the present might have what could be called "change blindness blindness."

Because these changes happen slowly, over a human lifetime, they never startle. They just tiptoe silently along, helping us all adjust to a smaller, shrunken world.

During a dive trip in Eastern Indonesia in 2005, Larry and Bonnie McKenna set out to capture footage of a Pacific leatherback turtle. After reaching a secluded beach via canoe, he encountered one of the majestic, endangered creatures first hand and experienced a spark of inspiration - he wished to see his new friend prosper.
Following a rigorous funding campaign, and largely thanks to the Diving Equipment and Marketing Association (DEMA), Larry’s dream came to fruition through a special organization: Save Our Leatherbacks Operation (S.O.L.O.).
Completely fueled by the passion of volunteers and generous donations, S.O.L.O. is a certified IRS 501(c) (3) non-profit charity foundation and a registered Texas environmental non-profit corporation. The organization’s three-fold mission agenda is to educate the public about the Pacific leatherback turtle and its plight, join people together in a democratic fashion to illicit change, and reverse the population shift via a series of hands-on initiatives and projects at nesting beaches.

Climate change has had a substantial negative impact on ocean life and the Pacific leatherbacks are no exception. As Pacific temperatures raise and water levels heighten, the reptiles’ nesting grounds are barraged
By intense heat and overwhelmed by flooding; many nestlings perish before they can properly hatch. According to McKenna, the threat facing Pacific leatherback turtles has far-reaching, though not immediately apparent, consequences to the oceans’ food chain. As the turtles primarily predate on jellyfish, which consume fingerlings, their extinction would cause a massive, irreparable crash in an already fragile environment.

Of special importance are S.O.L.O.’s partnerships with indigenous people residing on various islands in the Pacific. Because S.O.L.O. can only accomplish so much with its allocated visitation time, the hard work and dedication of local associates is vital to maintaining the mission. S.O.L.O. volunteers work closely with native villages and help provide them with the tools, provisions, and education necessary
To facilitate change. Banding together with locals, the organization has implemented several enterprises such as daily and nightly beach patrols, construction of protective fencing and scaffolding installations, and crucial data collection processes.

One of S.O.L.O.’s keystone fundraising and groundwork projects, Turtle Discovery Tours, allows participants to
Get a firsthand experience at the operation’s efforts and also provides unforgettable leisurely pursuits. This year’s excursion, slated to begin September 6, will take place in the Indonesian provinces of Bali and East Java in an area magnanimously titled “The Island of the Gods”. The
11-day tour includes a diverse array of activities and accommodations such as diving, snorkeling, traditional ceremonies, and much more.

Despite all the scientific advances made in the last century, there’s still so much we don’t know about marine life. Every day, whether in Antarctica or deep in the Mid-Atlantic the ocean has a way of constantly surprising us with new species of fish and other aquatic species. In a year full of exciting discoveries, here are three of the most quirkiest, most bizarre fish finds of the last year.

Earlier this year, scientists with the group Conservation International discovered Hemiscyllium halmahera, a new species of shark that uses its fins to walk on the seafloor. This bizarre fish, which is poses no harm to humans, inhabits the tropical waters of Oceania, including Australia and Indonesia. While reaching less than 4 feet in length, these fish have unusually long tails, perhaps used to help steer as it crawls along the ground. This nocturnal forager uses its ability to scour the seabed for crustaceans and other fish.

 

Dwarf Goby

Researchers came a new species of dwarf goby, dubbed Eviota santanai, in the waters of Timor’s first national park that sounds like a miniature monster. This bizarre fish stands out with a innocent pink appearance that belies multiple rows of teeth and up to three curved canines in the back row of teeth. Found in one of the most diverse aquatic ecosystems in the world, the fish stands out from its cousins with a different sensory system, lacking the pores many of its cousins have.

Perhaps the most bizarre fish discovery of 2013, Arapaima leptosoma is the first member of the group Arapaima to be discovered since 1847. The group survives in oxygen-poor swampy waters of the Amazon River by taking advantage of the labyrinth organ, a group of blood vessels opening into the mouth that allows it to “breathe” air. The fish is absolutely massive, at over six feet in length, and this particular subspecies distinguishes itself with a nearly flat forehead with a slender body. It’s amazing that a fish this big could evade discovery until 2013, especially given its ability to breathe outside the confines of water!

Aqua News: http://aquaviews.net/ocean-news/3-significant-giant-squid-sightings-history/#/ 

 

The legendary giant squid, once thought to be a myth, is an elusive creature that has captivated the imaginations of humans since we first set out on the sea. Mariners have reported sightings of the giant squid for hundreds of years, but the reports were often thought to be cases of misidentification or simply cautionary tales of the dangers of ocean travel.

These notions came to rest in the mid 16th century, when the first recorded specimen of giant squid washed ashore alive near a town in Denmark. Sightings of giant squid have picked up since then with improvements in research and technology, three of particular note which have taken place in the last decade.

On September 30, 2004, the giant squid was filmed in its natural habitat for the first time. A Japanese team, led by zoologist Tsunemi Kubodera, baited a line off the coast of the Ogasawara Islands of Japan. The team took multiple still photos of the squid showing its attack on the bait. This was the first time the squid’s hunting habits were caught on film.

 

First Live Giant Squid Video Emerges

In July of 2012, after continued research, Tsunemi Kubodera’s team became the first to obtain video of the giant squid in its natural habitat. As with the 2004 expedition, the team baited a line to entice the giant squid to come close enough for them to observe and film the squids hunting habits. The team witnessed the squid swimming against the current while holding on to the bait.

Largest Mediterranean Specimen Washes Ashore

The largest specimen ever found in the Mediterranean Sea was found on October 10, 2012 washed up on a beach in Andalucia, Spain. The specimen was dead when it was found, but was otherwise completely intact. Dissection of this squid in February of 2013 showed it to be thinner than the typical giant squid. This squid was preserved and displayed to the public.

Giant squid sightings have occurred since the beginning of maritime history, but the last 10 years have given scientists the most complete information about the giant squid to date. These giant squid sightings are certainly not going to be the last. As science searches for more information about the giant squid, sightings will become more plentiful. With more sightings, the legend of the giant squid will become more real than ever before

STORY HIGHLIGHTS
  • Marine archaeologists have found a shipwreck dating from the 13th century off the coast of Japan
  • The vessel is thought to have been part of Kublai Khan's massive invasion fleet
  • More than 4,000 artifacts, including pottery shards, cannonballs and anchors were found near the wreck

(CNN) -- In Japanese legend they are known as The Kamikaze -- the divine winds -- a reference to two mighty typhoons placed providentially seven years apart which, in the 13th century, destroyed two separate Mongol invasion fleets so large they were not eclipsed until the D-Day landings of World War II.

Marine archaeologists now say they have uncovered the remains of a ship from the second fleet in 1281 -- believed to have comprised 4,400 vessels -- a meter below the seabed, in 25 meters of water off the coast of Nagasaki, Japan.

Scientists are hoping they will be able to recreate the complete Yuan Dynasty vessel from Kublai Khan's lost fleet using a 12-meter-long section of keel. The Mongols ruled China from 1271 to 1368.

According to Yoshifumi Ikeda, a professor of archaeology at Okinawa's University of the Ryukyus, and head of the research team, the section could go a long way to helping researchers identify all the characteristics of the 20-meter warship.

"This discovery was of major importance for our research," Ikeda told a news conference. "We are planning to expand search efforts and find further information that can help us restore the whole ship."

Discovered using ultrasound equipment, the research team says it is the first wreck from the period to have an intact hull, the planks of which are still attached to the keel with nails.

Scientists say its good state of preservation -- they were even able to establish that the planks were originally painted a whitish-gray -- is due to the fact it has been covered by sand.

"I believe we will be able to understand more about shipbuilding skills at the time as well as the actual situation of exchanges in East Asia," Ikeda told reporters in Nagasaki.

More than 4,000 artifacts, including ceramic shards, bricks used for ballast, cannonballs and stone anchors have been found in the vicinity of the wreck, linking it to the Yuan Dynasty invasion fleet.

Ikeda said there were no immediate plans to salvage the hull and the first step was to conserve the find by covering the sites with nets.

The Kamikaze -- perhaps better known as the nickname given to the Japanese suicide pilots of the Pacific War -- were a nation-defining event for Japan and set the limits of Mongol expansion in the east.

Historians say the first Chinese attempt to invade Japan in 1274 ended in disaster.

Having initially engaged a numerically superior Japanese samurai force at the Battle of Bun'ei in First Battle of Hakata Bay, the Chinese retreated to their fleet of 300 ships and some 500 smaller craft after just one day of battle on land. A typhoon destroyed a third of the fleet that night and the remnants limped back to port in Korea which was then a vassal state of China.

Seven years later, Kublai Khan amassed an impressive armada of 4,400 ships carrying 40,000 Korean, Mongol and Chinese troops in a bid to finally subjugate Japan. The Japanese, convinced of a second invasion, had spent the intervening years building strategic seawalls which made it difficult for the Chinese to land.

Unable to gain a beachhead after initially taking the island of Iki and Tsushima, the fleet was decimated by a two-day typhoon that hit the Tsushima Straits.

It is believed about 80% of the fleet was destroyed and the Khan's troops either drowned at sea or slaughtered on the beaches by samurai.

According to a contemporary account cited in the book "Khubilai Khan's lost fleet: In Search of a Legendary Armada," by maritime archaeologist James P. Delgado, the losses were so great that "a person could walk across from one point of land to another on a mass of wreckage".
