“Don’t Touch The Coral” If you have ever been diving or snorkeling by a beautiful coral reef, you would have heard the strict instructions not to touch, or break the delicate coral which takes years to grow.  We are increasingly aware of the threats to our underwater ecosystems caused by bleached and damaged coral, but did you know about the increasingly popular movement of “Coral Gardening” which is helping to restore healthy coral reefs?

Causes of Coral Destruction

Coral has been measured to be declining at an increasing rate with roughly one quarter of reefs worldwide already damaged beyond repair.  Cyclones, pollution, warmer waters, and ocean acidity, as well as competition from seaweeds and predators are some of the main culprits.  Of course Scuba divers and snorkelers also can take some of the blame if they accidentally break coral, or contribute to pollution through use of destructive sunscreens. Destructive fishing methods such as dynamite fishing, or bottom trawling play a big part of the destruction in some areas. Coral mining is also an issue in some countries, where the living coral is harvested for use in bricks, building, road construction, and to be sold to tourists.

Coral Gardening – Aquaculture of Coral

Coral Reef Farming is the concept of extracting segments of larva of live corals from a reef and then proceeding to grow them in a nursery until adulthood. The technique involves treating coral as if it were a plant, leading to the name ‘Coral Gardening’. Coral Gardening has been enjoyed by many who have a coral display in an aquarium, and there are businesses who grow it for this purpose.  Now Coral Gardening is taking off as a popular conservation effort to restore and create beautiful coral gardens which help to provide the important part of the ecosystem for many underwater species.

How are Coral Gardens made?
Coral can either be reproduced sexually, or asexually by budding polyps. In the first method, spawn is collected, collonised in tanks then into floating nurseries in the ocean. The next step is to transplant it into the sea and secure it, then wait for it to grow!  The Coral can be secured with cable ties, rope frames, and other inventive measures to hold the coral in place.

The more current method is to source coral seedlings from reef colonies or stray coral fragments, by harvesting coral branches, fragments, or nubbins (pieces of coral pruned from the tips). This fragmentation is the most practiced method.

Become a Coral Gardener!

Although you may not go out and set up your own home coral gardening facility, there are places all around the globe where you can become involved in the process. Volunteer projects are available in places such as Fiji, Indonesia, Malaysia, Australia, etc… You can learn more about coral conservation and restoration by getting stuck in, and join an educational dive, such as a Project AWARE Reef Conservation Course where you can incorporate learning to recognize a reef in distress to you dives. Be sure to research the facility you plan to volunteer at to ensure you are working towards the greater good, in a sustainable manner. Remember it isn’t always necessarily hands-on; doing things like educating locals on how to preserve the reef can go a long way! Find out more about actions you can take within your own community too!   

In the meantime, here are some good dive practices to help you help the reefs! Consider taking our Peak Performance Buoyancy specialty to perfect your positioning in the water to avoid damaging vulnerable marine life! Fish ID is another awesome specialty that will help familiarize you with the underwater world; conservation starts with education.

If you would like to learn more ways to help the underwater environment, get in touch with us at Dive HQ Christchurch – 103 Durham Street South – 03 379 5804 – and we will introduce you to Project AWARE!

With winter now upon us, the air temperature has started to drop and the ski fields are finally open. Most of you have probably hung up your dive gear for the season and swapped it for a nice warm fire place, or a jacket and beanie when you dare to head out and about. The water is definitely getting chilly – I will not argue with that, but it could be a lot colder… Imagine if you were diving in somewhere like Iceland, in the Silfra fissure where the water is a freezing 2-4 degrees all year round. You would be crazy to do this without a dry suit.

The Silfra is known as one of the top dive sites in the world because of its crystal clear water and the crack in which you are diving. When you head down into the water you are between two continental plates; the North American plate and Eurasian plate. The water visibility between these two plates can be up to 100m, as clear as drinking water. The water comes from the Langjokull glacier and is then filtered through the ground for up to 100 years until it reaches the Thingvellir Lake. There is not a lot of life in this ravine other than trout, but it is beautiful none the less. The rock walls at some points almost meet, and you can touch both sides on the plates. There is a crazy green algae that grows on the bottom which they call ‘troll hair’. This UNESCO world heritage site is unlike anything you will have seen before.

So the next time you are thinking it’s too cold to go diving in New Zealand, remember it is about 10 degrees at the moment and that there are a lot of colder places in the world where you could be getting in the water! Also, some of the best diving around the South Island can be done over winter. The weather normally calms down and we get a constant Southerly swell rolling through. Think of all those amazing dive sites on the North side of Akaroa or Kaikoura that you missed out on diving over summer and do them now!

Remember we are having a Drysuit Demo Day on Saturday 30th July, so if you want to experience the toasty warmth of drysuit diving, let us know!

Give us a call on (03) 379 5804, or email us at sales@diveskiworld.co.nz. You can find us from Monday to Saturday, 8:30am until 5pm at Dive HQ Christchurch, 103 Durham St South!

Nananu-I-Ra; the name itself conjures up spectacular images of somewhere warm and tropical, but once you discover that the English translation of the Fijian name is ‘Daydream of the West’ it takes it to a whole other level. Breath-taking white sand beaches, clear turquoise waters, listening to the soft lapping of the ocean while you sip at your cold beer… This doesn’t have to be a mere daydream. This is where you will find us for a week in August! (Click here for details)

Nananu-I-Ra is situated 3km off the north coast of the main Island, Viti Levu, and accounts for a tiny 3.5 square kilometres of land mass. In other words, 3.5 km² of paradise! Even better than the sandy haven, is the surrounding underwater world. Being ideally located in the Bligh Waters means that Nananu-I-Ra provides prime access to a multitude of amazing dive sites. Not only this, but it takes a mere hour by boat to travel to the Vatu-I-Ra Channel where a fluctuating current flushes and nourishes the magnificent 300+ species of coral that form the reef. A plethora of marine life thrives in the area; beautiful tropical fish, both loggerhead and green turtles, reef sharks, and you may well come across a few of the endangered humphead wrasse, or the majestic bumphead parrot fish.

If you are looking to mix it up a little, then you will not be disappointed. At the centre of the Vatu-I-Ra Channel you will find the dive site E6, a site that is consistently rated to be one of the best in Fiji. Thanks to the seamount that rises from the deep almost to the surface, you stand a good chance of experiencing an encounter with many pelagics, such as large rays and hammerhead sharks! The area is also home to many manta rays, reef sharks, lemon sharks, bull sharks and even the odd tiger shark.

You may think that names such as ‘Dream Maker’ and ‘Breath Taker’ are exaggerations! Well just wait until you get under the waves and see for yourself! Just don’t forget your camera – you will want to take memories of this underwater utopia home with you.

Colour everywhere!

As well as being renowned for its phenomenal offshore reefs, Nananu-I-Ra is also known for its great windsurfing and kitesurfing opportunities. Explore the shores on foot or by kayak. Snorkelling is easily accessible from the beaches, and you will find plenty of idyllic spots to kick back and relax.
