Bastia fishermen Don-Jacques Pompa and his son Jean-Toussaint made an exceptional catch off the coast of Bastia, catching a 50 kg albacore tuna on Monday, June 1. A strong indicator of climate change according to Stella Mare. "I fell off my chair". Rémi Millot, a researcher at the University of Corsica and engineer at the Stella Mare laboratory, is still in shock. On Monday, June 1, he received a video from Don-Jacques Pompa, a Bastia fisherman who had just caught a 50 kg albacore tuna, or yellowfin tuna, on a longline. An exceptional catch for the western Mediterranean basin, given that this species is usually found in tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans. In the wake of this phenomenon, the researcher went to the old port of Bastia to study the phenomenon closely, conducting morphological surveys, scientific photographs, and several biological samples. An expertise confirmed by a specialist in tuna at the Ifremer-Marbec, a scientific partner of Stella Mare: "This is a species found in Tahiti, Réunion, French Polynesia, and in relatively warm waters," adds Rémi Millot. "Ifremer is very interested because it's an incredible data. Yellowfin tuna should not be present in our waters. We will try to study why..."
