CSTFA webinar - Eva Plaganyi-Lloyd - Models and methods for sustaining tropical fisheries in a changing climate
Sustaining marine fisheries in the face of changing climate and increasing human population size increasingly calls for complex decision support methods to underpin biological, economic and social sustainability of stocks and dependent users. In this talk, I present examples of tropical fisheries modelling and management, including how to climate proof fisheries and how ecosystem models called MICE (Model of Intermediate Complexity for Ecosystem assessments) are being used to support complex management decisions. First, I present examples of the two largest Torres Strait fisheries: tropical rock lobsters and bêche de mer (sea cucumbers), both of which have recently implemented new harvest strategies. My second example overviews fisheries in the Northern Prawn Fishery stretching from the Gulf of Carpentaria to Joseph Bonaparte Gulf. In addition to a number of recent extreme events impacting these fisheries, the region’s fisheries are facing additional risks due to anthropogenic water extraction and I’ll briefly describe how we are using MICE to quantify and mitigate cumulative potential risks. Finally I’ll present an example of an application of MICE to inform choice of ecological thresholds for coral-COTS (crown-of-thorns-starfish) management on the Great Barrier Reef.
