Mingas was monitored for 73 days and similarly traveled along the coast, all the way to Mozambique Island and across the Mozambique Channel to the NE coast of Madagascar, traversing 3,270 km (ca 2,025 km straight distance).Finally, Esperança was tracked for 2,608 km during 187 days. This turtle travelled along the coast approximately 250 km north (straight distance) of the nesting beach and reached, what is believed to be her feeding grounds on the Mozambique coast between Macaneta and Xai-Xai. This results shows that despite being protected nationally and internationally, poaching is still a serious threat to the conservation of marine turtles in Mozambique (and in the region), which warrants further efforts for their protection.
