Catalaphyllia Rehabilitation

Catalaphyllia Rehabilitated Before and After
Catalaphyllia Dying

This dying elegance coral (Catalaphyllia) came in on 24 November 2012 covered in aiptasia anemones and flatworms. Although I believed the flatworms were just Waminoa (nuisance, but not parasitic), but the previous owner was convinced the flatworms were actually parasitic. At the time, reports of LPS-eating flatworms were becoming more prevalent, so I wasn’t about to take chances.

This photo shows the coral in a dip to remove the flatworms and any other unseen parasites. I had to manually remove the aiptasia (chopping off parts of the old skeleton).

Only two days later (26 November 2012), and the coral was looking much better. (Only one piece of the Elegance is shown here.) With good water quality, I was hoping the coral would grow well.

Unfortunately, even seven months later (16 June 2013), the coral had not grown. Many rehabilitated corals often have stunted growth for about six months or so (some have had stunted growth for about two years). The coloration was significantly better though, with beautiful pink tips and fluorescent blue streaks reminiscent of lightning in the center.

Shortly after this photo was taken, the coral was permanently rehomed.

Coral Restoration in Curacao, Part III

Completed Staghorn Outplant

Classroom Outplant Rigging:

Practice Rig

Finally, after some great food and rest, we had our last classwork session with Coral Restoration Curacao.  This time we had to take the larger “frags” and outplant them onto the reefs.  We practiced with dead coral and a demo bench.  The instructor went through the different design iterations they had used.  I found it very interesting that their latest design utilizes vertical rebar and dual-horizontal bamboo poles.  The corals are then zip-tied twice (once to each bamboo pole) for stability. Our complete work is below.

Coral Restoration Diving the Outplants:

Staghorn Nursery Tree

On our last dive (Part II), we were able to frag about 20 colonies and replant them on the nursery. 

As shown looking up a nursery tree, we had to choose which corals to outplant, and we had to select the largest and most healthy “chunks.” I can’t call these “frags,” as these were monstrous. 

Corals to Outplant

Each coral “chunk” was placed into a weighted milk crate for transportation to the outplant site.

Transporting Staghorn Coral

And here’s me, transporting the corals to the site. Precious goods, coming through!

Outplant Stand

Here is our own outplant site, and this combination of rebar, bamboo, and zip ties will be the new home for a small Staghorn coral reef.

Staghorn Coral Frags

This crate of Staghorn corals was my responsibility. No pressure!

Staghorn Coral Outplant

Each Staghorn chunk was double-zip-tied, once to each supporting bamboo rod. Again, this was hard (especially when I accidentally slammed my ankle into some fire coral). It was really hard for me to concentrate after that – I became a bit paranoid! Remember, gloves are not allowed here! 

Conclusion:

Staghorn Reef

With any luck, our small little outplant will grow into a beautiful small reef soon, like the one pictured here.

Coral Reef

This Staghorn outplant helps a sand bar into a home for so much life while protecting the island.

Staghorn Reef

And maybe, the next time we return, Curacao will have a thriving Staghorn reef again, rivaling its original beauty.

Classroom Training on Populating Nursery Trees:

Supplies

Next up on our adventure performing coral restoration in Curacao was more classwork time during our surface interval.  On our previous dive (Part I), we cleaned the Staghorn coral nursery, and on this upcoming dive, we would get to plant small frags on the Coral Restoration Curacao nursery trees!

Coral Skeletons for Practice

First, we had to learn how to make the monofilament rigs to hold the corals and how to frag the corals.  We had to get the “frags,” secure the coral in the filament, thread the filament through the tree branch pipe, thread on a crimp (yeah, try not dropping those in the surge), and then crimp it secure.

Practice

Here, our instructor is showing us how to wrap the monofilament loop around the coral and cinch it tight. The instructor said they had better success if the corallites were slightly damaged in the process.

Coral Securing Practice

A loose loop would only allow the coral to move inside the loop in the current. This friction would continually damage the coral and permit algae to grow.

Securing Coral

Crimping the filament tight, crushing a few corallites, would cause the coral to regrow over the filament quickly, before algae could take over.

Crimping on the Tree

After our instructor secured the coral with monofilament, she threaded the filament through a hole in the nursery tree. We placed a crimp on top, ready for crimping. This was easy on our nice picnic table in the warm sun. This, in the current, felt nearly impossible.

Populating the Coral Nursery Tree:

Cutting Staghorn Frags

After our classroom work and lots of practice, we went out for our second dive. We found an “overgrown” Staghorn tree and began selecting pieces to frag.

Staghorn Coral Frags

We began collecting these Staghorn frags to replant on another nursery tree.

Staghorn Coral Nursery

Here is our newly renovated tree! This tree was originally a bit sparse, as its largest coral chunks were outplanted onto the reef. Our job was to take our small frags and hang them here. Easier said than done. Remember how we had to use those tiny crimps? Oh yeah, we definitely dropped a few and had to recover them from the silt. Once again, silly me, I thought this would be easy out on the dive.  I only managed to hang a whopping nine corals on our tree (my husband had about the same amount) in about an hour dive.  It was a lot harder than it looked. 

We did it

Here we are in front of our completed tree! It’s a great feeling, knowing that we were able to help with Coral Restoration in Curacao.

Enjoying Diving in Curacao:

Catching Fireworms

Of course, we had to catch some fireworms on the way back.

Barracuda at Cleaning Station

The barracuda greeted us on the way back again (sorry for all the silt in the photo.)  (This is a cleaning station – it’s not barring its teeth at us or anything.) What a great ending to a great dive!

Coral Restoration in Curacao, Part I

Coral Tree
Curacao

For our anniversary, my husband and I decided to revisit our honeymoon location:  Curacao.  It was also where we got our PADI Open Water scuba certification with Ocean Encounters and tried to catch the coral spawnings (with no luck).  So of course, this time around, we couldn’t sit still and just enjoy the island.  We had to get involved!! Coral restoration in Curacao seemed like the best way to volunteer while on vacation.

PADI Coral Restoration

My husband totally embraces my obsession with rehabilitating corals, so when he came across the PADI Coral Restoration certification offered by Coral Restoration Curacao, he signed both of us up!  Previously, my favorite dive of all time was working with Project Aware to clean up a small fishing island off the coast of Honduras, so this seemed to fit right in.

Coral Restoration Classroom Training:

PADI Coral Restoration Training

The certification class required classwork, three dives, and an exam (which wasn’t difficult… I thought I was just joking around that the first question would be “what is a coral…”  Whoops.)  

The class started off with our instructor, Vivianna, going over coral anatomy, coral pests, and the mission of Coral Restoration Foundation (CRF).  I felt so bad for the instructors because we asked a million questions and derailed all of the training!

Coral Model

The training materials included 3D-printed coral models to show their internal structure.

And, if you’re a total nerd like me, you can print off your own 3D coral model, which is downloadable for free on the National Oceanic and Atmospheric Administration’s (NOAA’s) website!

Coral Restoration Nursery and Outplant Familiarization:

Elkhorn Coral Outplants

Then, we went on our first dive.  We toured the Nursery and Outplant areas to get a feel of the area.  During our tour, our instructor pointed out the growth of various “frags” over time, pests, diseases, and other things we learned during class. Here are some Elkhorn coral outplants.

Fireworm Damage

Our instructor showed us areas of fireworm damage, along with how to use a drinking bottle as a trap.

Diseased Coral

We also visited diseased coral, so we can help identify areas of concern.

Coral Nursery

Next, we went to the Nursery.  We were assigned a tree to clean.  Our task was to use steel wool pads and scotch-brite pads to remove all the algae and fire coral from the tree.  That’s it. 

Cleaning the Coral Nursery:

Coral Tree

Ok, I really had no idea how hard that was going to be, especially with the ban on gloves.  Two people scrubbing a suspended tree, in some fairly strong surge, around critically endangered coral… and oh by the way… scrubbing fire coral just means the nematocysts get suspended in the water all around you.  That pretty much took up our entire dive… one tree cleaning… and there were LOTS of trees. 

Coral Tree Cleaning

Here, I am cleaning the coral tree, with steel wool and no gloves. Needless to say, FIRE CORAL HURTS!!!!

Clean Coral Tree

Eventually, our dive was over, and our tree was sufficiently clean for the coral to thrive. Time for a surface interval and more training!

Barracuda with Staghorn

On our way back to the beach, this lovely barracuda greeted us. What a great way to end a successful dive!
