Megafauna Monitoring Initiative

July 2019 marks the initiation of Tokoriki Diving’s Megafauna Monitoring Initiative (MMI). The primary purpose of the MMI is to quantify and monitor the local population of shark, ray, turtle and commercially valuable fish species many of which are either vulnerable, endangered or critically endangered. By doing so we are attempting to assess current population abundance and biodiversity levels, highlight seasonal changes in such levels, and observe if populations are increasing, decreasing or remaining constant over extended periods of time. Furthermore collecting such data allows us to accurately inform our guests; past, present and future, of what we are seeing and how often. The professional dive team collects the data on a daily basis from multiple dive sites within the Mamanuca group of islands.

So what did we see during our first month of the MMI?
