With pride and pleasure I’d like to announce the successful doctorate of Mialy Andriamahefazafy, which she defended publicly on July 13. Mialy’s previous work with a marine conservation organisation in coastal Madagascar showed her that local fishers were complaining about big boats fishing offshore, while in the inland capital, government officials were keen on the revenue they could gain through access agreements with foreign tuna fleets. This inspiration led to her thesis work, in which investigated the socio-material matrix through which fishing occurs. She narrowed in on three main topics: how diverse actors ‘access’ the fish, how these actors ‘narrate’ their concerns over overfishing, and whether there is any sense in approaching this issue by appealing to a sense of ‘regional identity’. Mialy undertook fieldwork in three countries (Madagascar, Seychelles, and Mauritius), interviewing more than 223 individuals including small-scale fishers, industrial boat captains and sailors, government officials, cannery workers, retailers and more. Mialy also observed landings of tuna in ports both big and small, and practiced event ethnography by joining delegations to attend two international negotiations.
