I recently got to travel to Trinidad to do some field work. Trinidad is an island located just north off the coast of Venezuela, and is actually part of the government of Trinidad and Tobago. I joined Shannon, a PhD candidate from the Walsh lab, and Dr. Matt Walsh to help begin a mark/recapture experiment with Rivulus killifish in local streams. We stayed in a town called Arima (or just outside of the town closer to the mountains). Our first day was spent getting set up with groceries and checking out one of the streams. Our first night out catching Rivulus was actually New Year's Eve. Armed with small nets we headed out to the stream behind the house we were staying in. Rivulus like to hang out in side pools where there is minimal water flow so we flagged certain pools and caught as many killifish from them as we could. Our first night we caught about 150 fish. The next day was spent processing the fish we brought back. We measured, weighed, marked (with elastomer), and took photos of the fish. Once done we returned them to the same pool they were pulled from. The next four nights and days were spent in the same manner but with different streams, some of which were high predation streams. With a few days before I left, we had a couple of free days. On January 5th we went to Las Cuevas Beach. Unfortunately it was a little overcast and rained slightly on us. But the beach was still nice. We went to another beach the next day, Manzanilla Beach. My last day we drove to Pitch Lake and explored areas on the other side of the island. Enjoy some photos!
