Today we set off to observe some parrotfish in the reef! We decided to highlight 4 species: striped, red tail, stoplight, and red band. Our research methods involve recording and following the fish around for 5 minutes and noting their behavioral patterns in the reef. We split into pairs and designated different portions of the reef to each group as to minimize the potential overlap there may be. Generally, we are asking what the parrotfish eat and which species are eating what. Tomorrow morning we are going to come back and analyze all of these findings.
(Striped parrotfish would occasionally venture in smaller numbers into the reef, but would spend most of their time in larger groups near the edge, constantly eating algae)
While we were out on the reef, I also saw a few piscivorous fish. On the surface of the water, I saw a few needlefish darting by. Near the reef edges, I observed a few groups of Spanish mackerel swimming together. I also saw several yellow jacks while observing the parrotfish. So far, I have not seen any of my piscivorous fish preying or attacking other fish, but I’m sure if I watch them for any extended period of time that’s bound to happen.

I sat out of the afternoon snorkel for some personal reasons, which was definitely the right call for me, and I got to rest up a bit, which felt really good.
This afternoon, we heard some presentations from the people who work here at Glover’s Reef. It was cool to hear about the goals and mission of the Wildlife Conservation Society (WCS), which is the parent organization that runs this station and several others. They aim to conserve and protect both the lands and waters of Belize, connecting the two. Also, they are making a special effort to manage the natural resources in a sustainable way.
The marine biologist here told us a bit about the fishing practices allowed that prevent damage to the marine ecosystems. There is a strict limit on the amount of fishing that cane be done, and there are guidlines in place for the popular conch and lobster seasons. There are also coast guards stationed here on the island who carry weapons and scare off any illegal activities.
The taxon presentations highlighted surgeonfish and wrasses, which actually both participate in some unique practices on the reef in which they clean other fish that would often be their natural predators.
