Fishing for survival: The forgotten slaves of Tromelin Island (Indian Ocean). (17th June 2019) - Béarez, Philippe
Abstract: Between 2006 and 2013, the island of Tromelin (Indian Ocean) was surveyed and excavated within the framework of the UNESCO project "Forgotten Slaves." Archaeozoological studies evidenced the survival behaviours and subsistence strategies implemented by the l'Utile shipwreck victims abandoned on the island between 1761 and 1776. The ichthyoarchaeological analysis of 4, 282 fish bones resulted in the identification of individuals belonging to 24 families of Teleostei and Chondrichthyes, among which Carangidae (jacks) largely dominate, followed by Serranidae (groupers), Acanthuridae (surgeonfishes), Balistidae (triggerfishes), Lutjanidae (snappers), and Pomacentridae (damselfishes). All of the cranial and postcranial elements were examined, and the taxonomic determination led to genus and species level attributions whenever possible. The composition of the assemblage, the ecology of the taxa, the nature of the nearby marine biotopes, and the fishing gear unearthed on the site provided helpful data to characterise the probable fishing techniques used by the survivors. Although line fishing along the drop‐off and offshore with a watercraft might have been practiced widely by the Malagasy slaves, spearing and/or harpooning on the sandbank and coral reef, as well as hand gathering in the tidal pools off the reef flat surrounding the island, could also have greatly contributed to the overall catch. The results of this study reveal that this broad‐spectrum exploitation of marine resources was opportunist, though it required skill and knowledge. They also shed light on the adaptation of the castaways to survive extreme conditions.
