Fish Populations Decline At Maeda Point – Not A Good Sign!

Posted on August 11, 2019 by Admin11

I originally got SCUBA certified at Maeda Misaki in 1992. I have seen this popular snorkeling location drastically change over the years with the increase in tourism. Meada point is now a high traffic area, literally thousands of people enter the water on a given weekend.

Maeda misaki diving

If you have ever been to maeda point you have seen the beautiful schools of Teira batfish (Platax teira). In the late 90’s there were massive schools of hundreds of these beautiful fish. Below is an old photograph I found in my photo album. This was a common site back in the 90’s.

Teira batfish at Maeda misaki

In 2017, I noticed that populations started declining.

Schools of batfish

2018-2019, I started seeing numbers decline to less than twenty individuals. July 2019, I went to the same location on three different days and didn’t see any batfish.

Wide angle macro

These fish are a huge tourist attraction. What could have caused the decline of the batfish populations? Possible reasons for decline:

Feeding the batfish man-made products
Noise pollution from an increase in boat traffic
Moved on to a safer location
Overfishing
Contaminates entering the water – sunblock, shampoo, perfume and urine

Fu (wheat gluten)

In the past, guides would feed the fish sausage and bread. In recent years many local companies switched over to Fu (wheat gluten). It’s much cheeper than fish sausage. Kilos of Fu enter the water for fish consumption on a given week at Maeda point. Could this gluten based product be good for the fish? Why you should not feed wild animals:

Interfere’s with their natural diet and feeding cycle
Makes the fish more vulnarable to predators
Reef algae overgrowth due to the fish being full
Increase’s your chance of getting bitten

Sometimes, I see plastic bags filled will remnants of fish food floating on the surface of the water. With the increase in tourism, I am finding more trash left behind at Maeda Point. This is a photograph I took recently at Maeda point. A collector urchin (Tripneustes gratilla) is covering up with discarded sausage wrapper.

This is one of my favorite photographs taken at Maeda Point.

Beautiful bat-fish

Hopefully the teira batfish populations are not a blur left behind.

Searching for the Amami Oshima Frog by Shawn Miller

Posted on August 3, 2019 by Admin11

The Amami Oshima frog is featured in National Geographic this month for the series ” Wildlife As Canon Sees It “

The Amami Oshima Frog (Odorrana splendida) is considered the most beautiful frog found in Japan. It is only found on Amami Island and is listed as an endangered species. It is one of the many endemic species facing extinction due to habitat loss. This protected species is designated as a living national treasure of Okinawa.

Scientific name: Odorrana splendida
Distribution: Amami Island
Habitat: Forest streams
Diet: Insects, worms, and millipedes
Average Size: 90mm-110mm

We were on the Island for a short period of time but managed to see eight Amami Oshima frogs. It rained the entire time but that didn’t stop us, we were on the mission to find the endemic species. I explored the island with Zoologist Valdimir Dinets and bat Scientist Jason Preble. We were fortunate to see the Amami rabbit, Amami Jay, Owston’s woodpecker, Hime habu, Ryukyu robin, Amami woodcock, Amami Spiny rat, Otton frog, Amami tip-nosed frog, Whip scorpion, Wood pigeon, Coral snake, Crocodile newt and the banded ground gecko endemic to Tokunoshima. Below are some of my favorite images of the Amami Oshima frog in it’s natural habitat.

We also found a small pond with Amami Oshima tadpoles.

Please pay attention wildlife crossing the roads at night.

Bottle Cap Challenge – No Kicking Just Picking!

Posted on July 6, 2019 by Admin11

The bottle cap challenge is a viral trend started by martial artist Farabi Davletchin. He was the first person to perform a precision spin kick and twist off the cap of the bottle using his foot. In 2017, I started a my own bottle cap challenge. The goal was to see how many twist top caps I could collect in fifteen minutes. Its an exciting challenge and I recommend getting others involved. Make it a friendly competition and document your beach trash finds using the Clean Swell app by Ocean Conservancy.

Over the years, I have seen a significant increase in the amount of marine debris washed ashore. The trash is from all over the world, but majority of it washes up from Korea, China and Japan

Next time your at the beach, take a minute and look around at the amout of single use waste on the beach. How do you feel when you see this waste?

Majority of the plastic bottles/caps that wash ashore become brittle and break down into smaller pieces. The smaller pieces (micro plastics) are harder to find and clean up.

Eventually these smaller pieces make it back into the ocean affecting the wildlife. Marine birds often mistaken and eat this plastic because it looks and smells like their natural diet (ex: fish eggs, crabs and small fish).

Even the marine fish will sometimes eat the plastic, they are attracted by the smell as well.

Hermit crabs are one of the few animals that can successfully adapt with our waste. They eventually move into this valuable real estate (plastic caps) and use it as a protective mobile home until they find a better option. Below are photographs of hermit crabs found naturally adapting with plastic twist caps.

This popular hermit crab was featured in honor of World Oceans Day 2019 on Stella McCartney’s website. Thank you all for bringing awareness to the plastic pollution problem.

Cryptic fish, Comets and Stars by Shawn Miller

Posted on July 1, 2019 by Admin11

The Comet (Calloplesiops altivelis) is a type of marine betta found in the beautiful waters of Okinawa. They hide in caves during the day. At night they come out to feed on small crustaceans. They are a mysterious fish and can be challenging to photograph. Comets are uncommon, yet very little is know about the behavior of these cryptic animals.

Scientific name: Calloplesiops altivelis
Common Name: Comet (Marine betta)
Distribution: Ryukyu Islands
Habitat: submarine caves
Diet: crustaceans and fish
Average Size: 20cm

Look close, can see the resemblance between the comet and the spotted moray eel?

When threatened the comet will stick its head into a hole and expose its tail end, which mimics the head of the a dangerous moray eel. The caudal fin also has detailed white lines that resemble the razor sharp teeth.

Having trouble getting close to marine life during your night dives? I recommend using the Light & Motion Sola 1200 red light feature. This feature enables the user to photograph marine life during the night without disturbing them. Most marine animals do not see the color red or react less to the red light.

Frogs of Okinawa by Shawn Miller

Posted on June 23, 2019 by Admin11

Individuals that study amphibians are know as herpetologists. The act of searching for these beautiful animals is known as herping. Okinawa has twelve species of frogs. They all have the ability to live in the water and on the land. Most are nocturnal and feed on insects during the night. They are found in local parks, forests, streams, puddles, and on the road at times.

If you would like to learn more about a specific frog, I attached a link above each photograph. Links in red are endangered species.

World Oceans Day 2019 – Okinawa, Japan

Posted on June 9, 2019 by Admin11

June 8th 2019, is designated as Wold Oceans Day. It’s a day encouraging worldwide awareness and action to protect our environment. We can all do a better job making a difference, our lives depend on it.

I have traveled to many of the outer Islands in the Ryukyu Island chain. Every Island has an abundance of marine debris washed ashore from Japan, China and Korea. Below are some of the documentation photographs taken on Iheya Island.

This post is not to make people sad, guilty or lose hope, It is to bring awareness to the ongoing trash problem in our oceans and on our shorelines.

The Shorelines of Iheya Island Turn Red

Posted on May 28, 2019 by Admin11

Mass coral spawning took place this weekend on Izena, Iheya and Noho Island. I have been waiting a very long time to see this natural wonder.

Coral spawn slick

Coral spawning takes place late at night during high tide. When many species of coral spawn on the same night it naturally forms a mass of gametes know as a coral spawn slick. These coral slicks eventually wash ashore the next morning. These brightly colored coral slicks give off a very strong odor that will stick in my memory forever.

While exploring the island we stumbled upon more bright coral slicks. We often explored beaches polluted with single use waste. As you can see our trash is a series problem in our oceans and the shorelines worldwide.

Noho Island had a thick smelling coral slick at the local fishing port. A group of locals showed up to go swimming but immediately decided it was a bad idea and went to another location.

Birding and Plastic Dreams by Shawn Miller

Posted on May 17, 2019 by Admin11

Birding is one of the most popular hobbies for all ages. I find it enjoyable and extremely relaxing. It doesn’t matter where I go on Okinawa, I seem to find beautiful animals and trash. The animals have been forced to live with our single use waste. Below are some of my documentation photographs of animals surrounded by our waste.

You can see how a bird could accidentally confuse single use plastic for actual fish. Now days, majority of marine birds have some form of plastic inside their stomachs.

This Gull arrived on Okinawa February 2016 with oil residue on its feathers. It spent most of the day bathing in the salt water trying to shake of the oil.

Even the endangered Okinawa rail (Gallirallus okinawae) has to deal with our waste.

Roadside streams are a great place to photograph waterbirds. This may look like a small waterfall but it’s actually a huge piece of plastic, beautiful isn’t it?

This post is not to make people sad, guilty or lose hope, It is to bring awareness to the ongoing trash problem in our oceans and on our shorelines. We all have the ability to make a difference by reducing the amount of single-use items we use daily.

The Red Coral of Okinawa by Shawn Miller

Posted on May 11, 2019 by Admin11

One of my favorite types of coral is the red knotted sea fan ( Melithaea ochracea ). Mainly because of the color and the branching pattern. The vibrant red coral, white polyps and the blue water compliment one another. There are many small marine animals that thrive on the red tree of life. This beauty was photographed in the blue waters between Izena and Iheya Island.

April 4th 2019, I stumbled upon some colorful micro flatworms that I have never seen before. Leslie Harris informed me that these fast moving slugs were potentially undocumented benthic ctenophores.

Name: Coeloplana sp
Benthic ctenophore
Size: 8mm-10mm
Location: Okinawa, Japan
Depth: 40feet

Can you see how well the benthic ctenophore blends in with its host? This is a great example of mimicry.

Look close at the tiny chamber mounds. These mounds hold the stinging tentacles that are used for catching food and possibly for protection.

I found this strange benthic ctenophore (Coeloplana sp) on a dive near Ikea Island. When I first saw the ctenophore, the long stinging cells were extended out in hunting mode.

Some benthic ctenophores live on starfish (Echinaster luzonicus), look close and you can see the stinging cells.

Testing the Nauticam NA-D500 Underwater housing

Posted on May 4, 2019 by Admin11

It’s been a blast shooting with the Nikon D500 DSLR combined with the Nauticam Na-D500 housing. I am pleased with the superior quality and design of the entire system. My underwater rig is setup for shooting macro with two Sea & Sea YS-D2 strobes and a variety of Sola lights. I customized it slightly by mounting a Light & Motion Sola compact tray and loc-line arm kit to the bottom of the housing. This allows me to easily attach other Sola lights underwater based on my vision.

My favorite features of the Nauticam NA-500 Underwater housing

Internal camera lock-to prevent movement
Vacuum and leak detection system, Green is good!
Port lock system and audible housing lock latches
Super responsive optic flash system
Comfortable hand grips

I tested the Nikon D500 system with the Nikon AF-S Micro NIKKOR 60mm f/2.8G ED lens and the Nikon AF-S DX Micro NIKKOR 40mm f/2.8G lens. Both are responsive and quality pieces of glass. The great news is that they 40mm is compatible in the NAU-18701 port as well.

Below are my favorite fourteen photographs taken with the D500 underwater in the beautiful waters of Okinawa.
