The key role of the Northern Mozambique Channel for Indian Ocean tropical tuna fisheries ArchiMer
Chassot, Emmanuel; Bodin, Nathalie; Sardenne, Fany; Obura, David.
The Northern Mozambique Channel (NMC) is a tropical area of similar to 1 million km(2) where pelagic fisheries supply proteins to more than 9 million people living in Comoros, Mayotte, and along the coasts of Mozambique, Tanzania and Madagascar. Although uncertain, statistics suggest that about 20,000 mt of tropical tuna and other pelagic fish are annually caught by artisanal fisheries in the area. The NMC is also a major seasonal fishing ground for high-seas fleets that export an annual average catch of more than 20,000 mt to tuna can and sashimi markets of high-income countries for a value estimated to be more than 100 million USD. The fisheries productivity of the NMC appears to be highly variable in relation to strong annual and seasonal variability in...

Improved version of the Tropical Tuna Treatment process: new perspectives for catch estimates of tropical purse seine fishery. Catches in the Indian Ocean ArchiMer
Duparc, Antoine; Depetris, Mathieu; Cauquil, Pascal; Floch, L; Lebranchu, Julien.
The Tropical Tuna Treatment is a process created at the end of the 90s by EU scientists to estimate catch of the tropical tuna purse seine fishery, for which logbook declarations were known biased. His main purpose is to provide the best estimations for nominal catch and catch effort spatially represented, to the RFMOs. However, the evolution of fishing practices and the extension of the fishing grounds have challenged the T3 methodology in some parts of it processing. Thus, the used of too large spatio-temporal sampling strata was specifically pointed out as the major cause of biases in the catch estimated. This paper presents the new methodology developed to fix this issue and implications on the output estimations compared to the previous version and...
