A Christmas reef clean up – making a difference

Here at Quo Vadis Dive Resort, we think that being a diver carries more responsibilities than just diving and looking at fish. As soon as you get certified as a diver, you don’t just learn about safe diving practices, but your instructor should also have taught you about the importance of being a responsible diver in regards to the environment.

The surface of the world as we know it right now consists of 71% water, and the oceans hold about 96.5% of all Earth’s water. Rain forests are responsible for roughly one-third of the Earth’s oxygen, but most of the oxygen in the atmosphere is produced by marine plants. The production of oxygen in the ocean is created by plants (phytoplankton, kelp and algal plankton) that live in the ocean. Same as plants on land, the marine plants produce oxygen as a byproduct of photosynthesis. This process converts carbon dioxide and sunlight into sugars that the organisms use for energy. One specific type of phytoplankton (Prochlorococcus) releases vast amounts of oxygen into the Earth’s atmosphere. It is the most abundant photosynthetic organism on our planet.

Phytoplankton creates the base of the marine food chain. The health of all organisms in the ocean is directly related to the health of phytoplankton.

So how can we help to save our oxygen?

Save the phytoplankton!

How do we do this?

Decrease you impact on pollution by using less energy (go to work via public transportation or your old school bicycle), help protect habitats on land and in the ocean (donate to organizations that can make a difference or volunteer on land or in the ocean by doing clean ups), encourage others to stop over-harvesting ocean wildlife (talk about the negative effects in the ocean of consuming predatory fish and also the consistency of mercury in bigger predatory fish and personal health risks that are related to the consumption of a lot of fish).

Since you see what is going on as a snorkeler or a diver below the surface, you can personally help out by not only telling how amazing the marine life is, but also the changes that you might have seen already over the last few decades. Your pictures and stories can help others care as much as you about the ocean and their habitants, and hopefully through your stories you can educate others about the importance of protecting our oceans. You are a diver, snorkeler, and with it you are the most important ambassadors to help protect our oceans and oxygen.

Want to make a difference soon?

Come and join us on our Christmas reef clean up and by diving against debris we will donate 500 Php of the money you paid for the dive to PROJECT AWARE to help save our oceans. Find us on Facebook or simply e-mail and sign up! See you on the 22nd of December!

Christmas Reef Clean up - 22qnd of December 2017

Christmas Reef Clean up – 22nd of December 2017

What exactly is coral??

Coral reefs are formed by groups of marine invertebrates that live together.

Each individual is known as a polyp. Corals feed by sticking out their tentacles into the water and catching drifting plankton and when they’re inactive, corals protect themselves by withdrawing their tentacles.

Large coral colonies you see are formed over hundreds and even thousands of years as polyp growth rates are extremely slow – up to 1cm per year.

When a polyp dies naturally a new polyp will form over the top. Repeated over many years, this process eventually results in the massive coral formations you will see today. As sea levels rise and fall over geological time the ‘active’ area of the reef changes over time. The white sandy beaches you see around these islands are produced by dead coral broken up over time in to smaller particles of calcium carbonate.

How Does Coral Feed?

Only a fraction of a coral’s food is from what is caught by the tentacles.

Coral’s main food source comes from a symbiotic relationship (mutually beneficial partnership) with photosynthesising algae collectively known as zooxanthellae.

The algae provides a coral with it’s colour. Without any algae, all shallow water coral would be white. The relationship between coral and algae is incredibly efficient, providing the following benefits:

Benefits to coral

Benefits to zooxanthellae

supplied with up to 90% of energy requirements as well as oxygen and aids with waste removal

safe environment to grow

provided with glucose, glycerol and amino acids for production of sugars, fats and most importantly calcium carbonate for reef construction

provided with compounds required for photosynthesis

Pescador island

Pescador Island is a small uninhabited island set in the Tanon Strait. The whole island above and below water is riddled with caverns and caves providing homes and cover for a wide variety of creatures like lion fish, octopus, sweet lips and moray eels. Spear fishing and all other illegal fishing methods are prohibited, so the inhabitants below and above water have some peace. The shelf, surrounding the island, 5 to 20 meters wide, can be seen from a boat and on calm days the scene is tantalizing.

Turtle

In the blue water surrounding Pescador you can sometimes spot turtles, trevally, small barracudas, mackerel and tuna that sometimes dart in like rockets to get some dinner, this is a very impressive sight!  Pescador Island translate to Fishermen Island. The reason behind is due to the massive sardine school that before were surrounding the Island and all the small fishing boats they attracted. A couple of years ago a typhoon hit the island and the sardines decided to move and today you can find them at Panagsama reef. Pescador is only one island but offers three very different dive sites

Entrance: Reached by a 15 min boat ride in a south-westerly direction. Boat entry.
Conditions: Depending on the wind, flat to strong waves. Often a medium to strong current in a south-north direction.
Depth: 0 to 50 Meters
Visibility: 15 to 40 Meters

Pescador Cathedral

The largest cave is “The Cathedral and starts at 18 meters and goes down to 40 meters. The scenery is breathtaking. There is a buttress at the top of the cave creating the impression of a church spire. Inside the cave we can spot nudibranchs, lion fish and sometimes scorpion fish. After the Cathedral the wall is not as colourful as the east and west side but its full of inverted walls and smaller caves to check out, where we can spot octopus and moray eels hiding in their holes.The wall contains scorpionfish, banded seakrait, sweetlips and you can also spot a frogfish or two hiding around the sponge corals.

Pescador East

Pescador East is just as beautiful dive site as the west side but very different. The wall dropping to 50 meters, and the sloping wall is dressed in big hard corals, here you can often see schools of inquisitive violet fusiliers and many other colourful reef fishes. You will start the dive at the south end where the famous coral garden is located. The dive will continue north and here we can see camouflaged giant frogfish pressing against a sponge coral. If you are even luckier you can catch them yawning. Devil-, leaf & bearded scorpionfish are also found at the wall. You can also find a lot of other life like sea moths, clown trigger fish, reef octopus, nudibranches and lots more. Don’t forget to take a look out in the blue and you might spot schools of big eye trevally’s, sardines, butterfly fish and red tooth triggerfish.

Pescador West

When you do Pescador west, you will jump at the south coral garden and after that you will continue north direction with the reef on your right side. At 15 meters and deeper you find colonies of soft corals in all different colours on the steep wall and if you shallow up you can see large hard corals, surrounded by reef dwellers attract an incredible variety of marine life. The wall is filled with spectacular crevasses, over hangs and caves, inside them we can find sweetlips and groupers. Quite simply it is a paradise for divers. You can set your eyes on creatures like frog fish, clown trigger fish, stone fish, devil scorpion fish and a different nudibranchs and in the end of the dive you might get a glimpse of the cathedral.
