The project aimed to improve our understanding of the daily and seasonal movements of commercial finfish and octopus in Rodrigues and to assist policy makers in the development of strategies that will protect vulnerable species and improve fishery sustainability. Over 300 commercially important fish, caught within the Anse aux Anglais and Grand Bassin marine reserves were tagged using T-bar tags and their release position was marked; fishers were then encouraged to return any captured tagged fish. Field trials were undertaken to assess the possibility of acoustically tagging octopus to track their movement patterns around the lagoon. Seven bluespine unicornfish were also tagged with acoustic tags and their movement patterns tracked over a 2 month period using a directional hydrophone. Unfortunately, none of the fish tagged with T-bars were recovered, therefore future studies will need to tag a larger number of fish. Tagging of octopus was successful but more field trials are needed to determine to what extent tags influence the behaviour of animals released back into the natural environment. The study of unicornfish indicated that the fish do not move large distances and all 7 individuals remained within the Grand Bassin marine reserve throughout the study, occupying <2% of its area. This is important for management of this species, suggesting that the population will benefit from the development of the network of marine reserves in Rodrigues.
