An awesome few weeks as always at Aquanauts Grenada

A Happy New Year to you all. I hope everyone has recovered from Christmas and is ready for a fabulous 2015.

We have had some great sights over the last few weeks. 

Our dive site 'Kohani' didn't disappoint when it gave us two beautiful longsnout seahorses, as well as the usual viewings of Spotted Moray Eels, beautiful fish, crabs and lobsters of varying sizes, and gorgeous corals.

One of our deeper wrecks 'Shakem', a inter island cargo vessel that sunk once it started taking on water which reacted with the concrete on board (concrete and water doesn't mix well!), has had 2 resident frogfish on it for the last month. Frogfish are usually found as a mating pair; the female is larger than the male and when the pair is ready to move on to pastures new, the female will carry her mate on her back. Our pair consists of a red female and a green male. They are found near each other but not together. 

One of our most popular dive sites is 'Shark Reef'. It is as close to a guarantee to see sharks as we can give. Most often we will see multiple Nurse Sharks, mainly small ones who like to hang out under ledges, but we also get specimens who are up to 2m in length and free swimming on the reef. We also get to see large king crabs, lobsters, stingrays, turtles and octopus; including the image below which shows an octopus having a little lunch snack on a crab.

Our marine park trips are always busy with divers and snorkellers who love to see the marine life as well as the underwater sculptures at 'Molinere Bay' that Grenada is famous for. There is a new sculpture currently under construction that shall be installed soon, so watch this space for pictures when it is ready to be explored. The divers and snorkellers have been treated to some whitenose pipefish, large rainbow parrot fish, humongous Goliath Grouper and reef octopus.

Some other sights we have had over the past few weeks include a Bluespotted Cornetfish (looks similar to a trumpetfish, but the tail just grows out to a point) on 'Veronica L'; two fabulous night dives on 'Veronica L' where we saw many large king crabs, basket stars and an octopus who showed us his amazing colour changing abilities; 3 Caribbean Reef Squid were spotted on our shallow wreck site '1/4 Wreck'; and a leopard flatworm and small reef Scorpionfish out on our reef at 'Purple Rain'.

So what are you waiting for, book your diving trips with Aquanauts Grenada for 2015 now. And come and see some of the best diving the world has to offer!!!!

King Crabtopus

By Chrispin

On the 1st of December, going down with a few other divers on one of our most beautiful reefs called Windmill Shallows, there sits a fairly old wreck to the left of that reef if the currents going down, called the Rum Runner.
As we approached the wreck, we all saw the strangest thing.
It was a king crab and an octopus in a scuffle, but the octopus seemed to be winning as the king crab was defenseless under the strong master lock of the octopus. We all felt sorry for it but were also excited about how this was going to turn out.
We spent like 20 mins looking at them slowly move into the wreck with the scuffle as we were slowly running low on air--obviously we planned on seeing much more than that--so we decided to leave and hop back to the amazing reef and continue the dive.
Clearly, since Sci-Fi exists, At the end we all knew what we thought it was, "The King Crabtopus!"

Manta Rays - a not too common sight in Grenada; nevertheless a frequent visitor to our waters.

Manta rays are large eagle rays belonging to the genus Manta. The larger species, M. birostris, reaches 7 m (23 ft) in width while the smaller, M. alfredi, reaches 5.5 m (18 ft). Both have triangular pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Elasmobranchii (sharks and rays) and are placed in the eagle ray family Myliobatidae.
Both species are listed as Vulnerable by the International Union for Conservation of NatureAnthropogenic threats include pollution, entanglement in fishing nets, and direct harvesting for their gill rakers for use in Chinese medicine. Their slow reproductive rate exacerbates these threats. They are protected in international waters by the Convention on Migratory Species of Wild Animals, but are more vulnerable closer to shore. Areas where mantas congregate are popular with tourists. Only a few aquariums are large enough to house them. In general, these large fish are seldom seen and difficult to study

Recently we have found Black Brotula Fish on our reefs, in particular around Veronica L wreck. A fairly rare sight, this unusual fish is an interesting sight, more looking like an crossbreed between an eel and a fish. Brotulas are a family, Bythitidae, of ophidiiform fishes, also known as viviparous brotulas as they bear live young. this fish are shy and usually retreat on the approach of divers. However with patience we were able to get some good pictures of this rare sighting.

The new Ocean Health Index is out and Grenada has laid out what it needs to do to move forward: In Overall ranking Grenada scores 48;

# 11 for sustainable seafood provision - small fishing industry works with sustainable practices.

# 85 for Local Fishing Opportunities - not enough marine protected areas to sustain small close to shore fishing.

no Natural non food products are harvested in Grenada

# 36 for Carbon storage in our coastal system - could be better if we had more mangroves left.

# 39 for coastal protection which measures jobs, wages and revenues of the marine work force - fisherman are better off compared to other jobs available on the island.

# 97 for coastal likelihoods measuring marine related jobs like harbors, marinas, suppliers.

# 25 for sustainable tourism and recreation, protecting the marine resources while sharing it with tourists and generating jobs and revenues for the local community.

# 32 for sense of place or what percentage of our coastal areas are actually protected - we can do much better here.

# 82 for clean waters - this is our weakest point, sewerage from the town of St. George's still goes unfiltered into the ocean, the sewage pipe by the airport is broken since 2004, this is in urgent need of attention.

# 69 for biodiversity, Grenada boast a great variety of marine life.

The Caribbean Lionfish has arrived in Grenada with a vengeance. The Caribbean Lionfish is an invasive species who has no natural enemies in the Caribbean, grows much biggers than its Pacific counterpart and feeds on all the smaller reef fishes and juveniles. Hence being a threat to the diversity and balance of the Caribbean Reefs. Our first sighting was just 9 month ago now they are everywhere! However most of them are not big enough for the pan (yet), so we just kill them and leave them to be eaten by other fish and eels. We hope they develop a taste for it and help us to control this species. Reports from the Bahamas show that after 10 years finally other predators are taken care on the problem among them sharks and groupers. However it took them a while to figure out this strange looking nevertheless beautiful fish is food too.
