Week three and four on the Marine Conservation Project was spent continuing the fish spots with the adult and juvenile species, but now we also needed to size each fish to the accuracy of 1cm. This seems like a fairly easy process however it is a little difficult as water magnifies the fish. After a few sessions I found my accuracy was almost perfect. Next step was to start monitoring. This is when things got quite tricky.
Imagining floating at a constant depth of about 15 meters, only using your breath to maintain buoyancy, holding a one-meter T-bar in front of you to count fish in a 2 meter cubed box, navigating a perfect straight line for 30 metres using a compass while being swayed gently with the current, and holding an A4 slate with various species of fish listed on it, then recording a tally of the fish species and size as you swim slowly along the 30 meter transect line. Hearing it is one thing, doing it is a whole set of challenges all wrapped together. The first time I tried the transect I felt quite overwhelmed. The second time however, I felt much more comfortable and a lot more confident that I could actually collect some data that could be used for the research of the biodiversity of the coral reef.
Some of the highlights while diving during week two and three were seeing Nurse Sharks, turtles, Southern Stingrays, Spotted Eagle Rays, Tarpons and Barracuda.
Some days ended up being non diving days due to weather. On these days we had lectures on Mangrove, lagoon and reef ecosystem relationships, Taxonomy and First Aid.
On our day off on week 3 a group of us decided to goto the Northern hemispheres largest coral atoll called Banco Chinchorro to do some diving and check out the giant iguanas and crocodiles on the island. It was a 2 hour boat ride from Mahuahal in choppy seas. As we got close to the island we were greeted by a pod of about 20 dolphins. They stayed with us for about 5 minutes, riding the bow of the boat and swimming besides us, jumping out of the water. It was a lovely surprise and everyone was very excited to see them. Some people seeing dolphins for the first time. It was a lovely reminder that it is so much nicer to see dolphins in their natural environment rather than in a place like Sea World. The diving at Banco Chinchorro was lovely. The coral was extensive and regularly we would see single pieces of coral and sponges that were bigger than us. On the dive we saw a Spotted Batfish, a nurse shark, Loggerhead Turtle, as well as heaps of Parrotfish, Wrasses and even saw a few Spotted Trunkfish.
Towards the end of week four I had an amazing dive with bunch of Barracuda, walking back into shore I was stung by a stingray in the foot. The pain was intense and felt like a stinging ache in shot in waves in my foot sending it into spasms. The treatment was to immerse my foot in scalding hot water. NOT FUN! Pain subsided in about 90 minutes luckily. I'm bruised at the point of entry. The pain disappeared completely and I was left with a small bruise which I still have now 4 days later. No current problems with the wound. I’m now waiting for my stingray superpowers to metamorphasise!
I just had an awesome snorkel with giant puffer fish, 4 squid, lots of surgeon fish, trumpet fish and juvenile damsels. One squid hung around us for a good few minutes then flashed translucent and inked right in front of us! So cool to see that right in front of you!
