This morning, we set off to study the differences between Marine Protected Areas (MPAs) and non-MPAs. We wanted to survey the different areas and observe differences in algal growth, coral structures, fish biodiversity, bleaching, and general species presence. To do this, we decided to utilize quadrant sampling. We hypothesized that the MPAs will have higher biodiversity and greater reef health as compared to non-MPAs.
Out on the reef, I saw so many yellow jacks! I actually saw some preying on what appeared to be some clown wrasses near the edge/by a reef drop-off. They were very quick and would swim off as soon as they had caught the wrasse in their mouth. We also saw a dolphin swimming by the boat on our way back to the island!
After returning from our morning adventure out on the reef, we compiled all of the data each pair had collected and observed the results. In general, our findings were a bit inconclusive and there was quite a bit of margin for error.
Our presentations today were on cryptobenthic fish, groupers, and a deeper dive on wrasses. The cryptobenthic fish presentation was interesting and a bit eye opening, as the quantity of these small fish is actually so great and their entire survival strategy is dependent on constantly reproducing in vast numbers.
