PADI IDC Gili Islands, PADI Career Development Dive Resort

Yesterday Oceans 5 dive resort organized another reef clean up. Instructor Phil, Divemaster Yvonne and Divemaster Trainee Budi took care of 7 other divers who wanted to help. The clean up started at 16.00. At that time the preparation started with preparing the bags, the gloves and all the equipment. At 16.30 Divemaster Yvonne gave a dive briefing about how everyone should take the rubbish away, the bottom time, the max depth and buddy teams. The first divers came after 44 minutes out of th water. They had 3 bags full of rubbish. After this each buddy team and the result was shocking...... After we had last time 15 bags of rubbish now the divers collected another 12 bags of rubbish! It looks a little bit better in the front of Oceans 5 dive resort, but still a lot of work has to be done. For further information about the reef clean ups: info@oceans5dive.com

It was time for their release. After being at Oceans 5 for 8 months these Hawksbill sea turtles were ready to return to their home, The Ocean. The people who were taking care of them, Nun, Uding and Bahry, helped to get the turtles to the beach. There they were released! Some of them were shy and didnt know what to do with their freedom, other enjoyed the first minute and run into the ocean as it was not new for them. A new adventure has started for them, they have to swimm and catch their own food. Hopefully we see them in the future underwater! Enjoy your stay turtles, see you soon.

Description All twenty-five species of trevally have elongated, compressed bodies and deeply forked caudal fins, with long, sickle shaped pectoral fins. The Giant Trevally (also known as the ulua, ronin jack and “GT”) is the most prized of the species by anglers and is identifiable by an ovoid patch of small scales located on the breast ahead of the ventral fins. Coloration for the Giant Trevally can range from silvery-white to almost jet-black. The Giant Trevally uses its superior swimming abilities and power to hunt and smash baitfish. The Giant Treavally is known for stunning prey with its first strike and then circling back to engulf the wounded and/or disoriented baitfish. They will usually devour the prey quickly with one bite, as competition can be fierce from other members of the pack. As they grow, larger specimens move to deeper water and congregate over coral reefs and other underwater structure. Giant Trevally also venture onto flats, headlands and shallow water...

Porcelain crab Neopetrolisthes maculatus These delicately spotted crabs live in a symbiotic relationship with anemones. They keep the anemone clean while benefiting from its protection. Porcelain crabs have modified mouthparts which open out like fans into the oncoming current in order to trap tiny particles of plankton . Life span They live for around 2-3 years. Statistics They are less than 24mm in width. Distribution They are found in the Indo-Pacific. You see them when you are diving around the Gili Islands Indonesia . Habitat They are also known as anemone crabs, due to their close association with anemones. Porcelain crabs may be found singly or in pairs, hidden between the stinging tentacles, or near the mouth, of anemones. They are found in reef habitats, to depths of around 10m. Diet They are mainly plankton feeders, sieving tiny particles from the water column using their fan-like mouthparts. They also eat mucus from the anemone. Behaviour Por...

Why Nitrox? Nitrox exposes you to less nitogen. This has the advantages of longer allowable bottom times, less need to push the air no decompression limits and less overall nitogen load when making multiple dives. Oceans 5 dive resort offers Nitrox course. They start every day. If you are 12 year old and older and you have an Open Water Certification you can begin. Enjoy the tast of Nitrox!

TRUMPETFISH (Aulostomus chinensis) Also known as Trumpet, Atlantic Trumpetfish, Caribbean Trumpetfish, Trumpeter and Painted Flutemouth. You can find them everywhere around the Gili Islands when you are snorkeling or divinvg. The Trumpetfish can be recognised by its long body, tubular snout with minute teeth, its chin barbel and the series of short dorsal spines.Their bodies are inflexible, supported by interwoven struts of bone. The colouration of this species is variable. It is often brown or green with pale stripes and bars, and white spots posteriorly. A yellow colour variety is common in some areas. Individual fish have the ability to change their colours very quickly. Trumpetfish have the capability to rapidly expand their jaws into a circular gaping hole almost the diameter of their body when feeding. The trumpetfish is the true master-hunter on the coral reef. Yes, this fish looks rather benign and yes it is a relative of the passive sea horses, but it is truly a fish-ki...

There are a few different kinds of decompression stops/ pauses in ascent, which a scuba diver needs to make to allow for the expelling of inert gasses to minimize the possibility of the gasses forming micro-bubbles which in turn can cause Decompression Sickness or DCS. In this article we take a closer look at the Safety Stops. Safety Stop Every recreational scuba diver has been taught to perform safety stops while learning how to dive. A safety stop which is a 3 minute halt, assists the body in rapidly eliminating nitrogen. Even a diver that has remained within Decompression Limits is susceptible to bubbling on ascent and the safety stop helps mitigate the chances of this happening by speeding up the off-gassing process. A diver that performs a 3 minute safety stop after a dive will have less nitrogen in their body immediately upon surfacing as compared to a diver that did not perform a safety stop, but has been on the surface “off-gassing” for 3 minutes. Therefore, no matter w...

What is coral bleaching? A coral colony is made up of numerous individual coral polyps. Corals use their tentacles to feed on zooplankton, but depend primarily on microscopic, algae known as zooxanthellae located inside their tissues to provide them with food. Corals are very dependent on this symbiotic relationship, receiving up to 90% of their energy from the zooxanthellae. Healthy corals usually appear tan, brown or green from the presence of the algae within their tissues. Some types of corals have additional pigments so may appear more blue or purple. Coral bleaching is a stress response that occurs when the coral-algae symbiotic relationship breaks down. The term “bleaching’ describes the loss of color that results when zooxanthellae are expelled from the coral polyps or when chlorophyll within the algae are degraded. When the zooxanthellae leave the coral, the white of the coral skeleton is then clearly visible through the transparent coral tissue, making the coral...

When you are diving around the Gili Island you will spot them on every dive site . Some people loves them other one say this one of the most ugly fish in the sea. We are talking about the Parrotfish. This herbivorous fish uses its strong beak-like mouthparts to scrape algae and other plant matter from the surface of the coral. This maintains the health of the reef by keeping algae in check, which could otherwise overwhelm the delicate reef ecosystem. An unusual feature of parrotfishes is that they are able to change sex, with females becoming fully functional males. In a population, parrotfish start off as either females or males (known as primary males). Females may at some point in their life become male (secondary males). Populations that have these two types of males are called ‘diandrous’, meaning ‘two-males'. A terminal phase male defends a territory and a harem of females. If the male should die, the most dominant female will become the dominant male, her ovaries beco...
