Ana Barbosa Martins
Refining the ecological role of stingrays in coral reef ecosystems
Ana Barbosa Martin's education and career began in Brazil with an undergraduate degree in Biological Sciences and a master degree in Biodiversity and Conservation from Universidade Federal do Maranhao. During her masters, Ana developed a research project focusing on the use of fisher and trader knowledge to describe the shark catch, produce a supply chain and evaluate perceptions regarding the regional conservation status of shark species in Northeastern Brazil.
Ana Barbosa Martins is a Brazilian PhD candidate based at James Cook University. Currently, Ana is developing a research project that aims to examine the role juvenile stingrays’ play in coral reef ecosystems and how important these ecosystems are to their populations. To answer these questions, Ana is integrating acoustic and GPS telemetry to assess juvenile stingray movement patterns and habitat use. In addition, Ana is using stable isotope analysis and non-lethal gastric lavages to evaluate juvenile stingrays and sharks trophic roles at Orpheus Island.

Understanding barriers and opportunities for sustained benefits from tilapia (Oreochromis mossambicus) pond aquaculture for Solomon Islands Households.
After completing undergraduate studies in 2010, Daykin worked as a research assistant in socio-economic surveys and analysis on gauging coral reef goods and services usage in rural communities in the Solomon Islands. In 2012, he took up a position with WorldFish as a research analyst. In this role, Daykin focused on community-based fisheries management, ecosystems approach to small-scale Fisheries Management, and rural inland aquaculture development (tilapia & milkfish). In 2013, Daykin became the Hub Manager of one of the WorldFish program offices in the Solomon Islands, overseeing implementation of various donor funded projects under the then Aquatic Agricultural Systems Program implemented by WorldFish. Daykin has also led work on tilapia aquaculture development with rural farmers in inland communities, partly for extension purposes but mainly to inform research on the viability of homestead tilapia and milkfish pond aquaculture in the Solomon Islands.
Daykin is currently doing a Master’s by research program at James Cook University on understanding the barriers and opportunities that exist for homestead tilapia pond aquaculture in the Solomon Islands for rural households; in a rural developing context of the pacific islands. Findings from this research project will not only be relevant for his Master’s thesis but also in informing the Solomon Islands National Government and relevant Non-Government Organizations on ways forward for development of the rural tilapia aquaculture sector in the Solomon Islands.More Details
