Mataking exploration

Yesterday we travelled to Mataking and dived on the far side of the islands, it was a turtle mecca there, we saw 6-7 before we even started the dive, however the number of fish was much lower than at Pom Pom and overall the dive was no less entertaining than most dive at Pom Pom.



A few days ago in the afternoon we did a fish survey from the Pom Pom Northtip jetty where I saw my first Hawksbill of this trip, 4 Green Turtles and a meter long Bumphead parrot fish hiding under a large coral. 

The marine life is great and so many turtles.

Big Fish Surveys

I have been a volunteer and science intern at TRACC for just over two months and the journey has been amazing. The work and effort that TRACC has put into conserving and rehabilitating the marine creatures has shown a significant difference since they first started. There are many conservation projects that TRACC does but one of my favourites is the large fish survey. 

Plectropomus are indicative of healthy reef.
The very first large fish survey was done in 2011 when TRACC first arrived on Pom Pom Island and the fish are still being surveyed and added as data. The reason for this is because we want to know if the coral restoration and artificial reefs are attracting fishes. According to the data, there has been a drastic increase in the number of large fishes since 2011.

Before my first large fish survey, Tom, the senior science officer, made sure that we knew how to identify the large fish families such as sharks, rays, triggerfish, groupers, sweetlips etc. As soon as we'd gone through the fish identification, we jumped into the water right away. On that very first fish survey dive, I had trouble identifying all the different types of large fishes but Tom guided and made sure I improved at identifying the large fishes. Thanks to him, by the time I'd done 3 fish surveys, I felt like a pro! Now, after weeks of surveying, I am taking over and leading the fish survey with new volunteers that are in TRACC.

I personally think that a fish survey is like a treasure hunt. Every large fish that we find is like finding gold! And stingrays are like finding platinum! One of my favourite fish surveys was when we saw three eagle rays in one survey and one of them swam right over our heads. That was one of the best dives I've ever had; not just to see an eagle ray but also to see it swimming so close.

Another great fish survey experience was when I saw my first bumphead parrotfish. Those parrotfishes were about a meter long and had teeth that were so big they looked like they were wearing hockey gum guards. They seemed intimidating but they are one of the gentlest creatures I've ever met. During my survey, 13 of them parrotfishes were eating in a land full of corals. Somehow they really reminded me of a herd of cows.


These are only some of the many things I've experienced during my science internship and I'm only just beginning. Through diving and fish surveying, the ocean never fails to surprise me. I am learning new things about the ocean everyday and there is never a dull moment. I am definitely looking forward to getting on with the next fish survey and I will be sure to go in to the water with an expectant heart, knowing that in every fish survey that I do, I will be in awe.

Artificial Reef Part 3 -- Bottle Reef Survey's and Sea Creatures


James Surveying the Reef
James gently sways in the hammock on a sunny afternoon as I lounge beside him in one of the white pliable plastic deck chairs so typical in the communal area of Number 4. He is clad in his usual apparel of swim trunks, me in mine of bikini and well-worn oversized tank top.  Casually, we talk of the work he has done surveying the biodiversity of the bottle reefs planted by TRACC and the pleasure of seeing increased biodiversity return the tiny white-rimmed paradise of Pom Pom Island.

James McElroy works primarily to assess the impact of bottle reefs as a healthy reef structure in depleted reef ecosystems, and “satisfied” is the word on his lips. The actual work of the surveys take place while diving and the posture of James as he surveys the bottle reefs and the test sites, which are patches of coral rubble that once were healthy reefs, is one of calm concentration. He hovers in the water a little aside and above the

sites, marking species in pencil on a white plastic slate – later pouring over species identification books to figure out exactly what grouper he saw, or what that particular wrasse with blue and green sides and orange fins was that’s been bothering him all week.

His surveys take place over 9 weeks and utilize 72 identical bottle reefs planted at 6 different sites scattered at intervals around the island for the purpose of his experiment. Preliminary results indicate
a higher number of species and greater biodiversity as compared to the test sites. Over 50 different species have been recorded as populating the new bottle reefs, among them a resident moray eel hiding in the shadows of the concrete base, a blue ringed mimic octopus chameleonesque in its color changing abilities, and a rose patterned batch of nudibranch eggs.

The Survey Team at Work
James is satisfied not only to directly see the results of the bottle reefs, but also expresses a satisfaction in his contribution to TRACC: “To quantify the conservation impact we have made on the biodiversity of these originally barren areas is important for the credibility of TRACC and the techniques we are using.  In a small way, I feel like I’m working as an auditor outside of TRACC by analyzing the work the organization has done.”


Yet, at the heart of it James, like all of us at TRACC is the most pleased with the results apparent through what we directly see at the bottle reefs, “When I’ve spotted two species on a control site and 14 on a new reef, its satisfying as a conservationist to see the effect of the new reefs i built”.
