Charlie is investigating the ecology and biology of sharks, rays, and chimaeras. This includes studying how often they reproduce, how old they are and how fast they grow, what they eat, as well as where they go and how much time they spend in specific areas. The information obtained from these projects is then put together to obtain a better understanding of the role of these apex predators within their ecosystem. Sharks play a vital role within their ecosystem, with studies showing that the depletion of large predatory sharks can lead to the collapse of other fisheries.
Charlie’s research also includes the collection of information needed to implement mathematical models to estimate sustainable levels of catches, and to recommend management regulations that will ensure the sustainability of shark fisheries. Consequently, this will provide long-term returns for fishers and their dependent families and improve the economy of the fishing industry.
