“…The quota granted to Algeria has been increasing exponentially over the last decade; in 2000 it was 130 tonnes while in 2019 it reached 1437 tonnes("ICCAT•CICTA•CICAA," 2019) ,(International commission for the conservation of atlantic tunas). Nevertheless, few scientific works showed interest in this species during the last decade; only six works along the Algerian coast could be found (Nouar and Labidi, 2009;Abdelhadi et al, 2011;Nouar (2013a, 2013b); Neghli and Nouar, 2014).In this study, thegeo-referenced fisheries data were integrated with remotely sensed oceanographic datasets to answer the following questions; firstly: How does the environment contribute to the temporal distribution of bluefin tuna? The conditions favourable to the temporal distribution of Thunnus thynnus, Bluefin Tuna (BFT) were determined.…”

We analyzed the movements of Atlantic tuna (Thunnus thynnus L.) in the Mediterranean Sea using data from 2 archival tags and 37 pop-up satellite archival tags (PAT). Bluefin tuna ranging in size from 12 to 248 kg were tagged on board recreational boats in the western Mediterranean and the Adriatic Sea between May and September during two different periods (2000 to 2001 and 2008 to 2012). Although tuna migrations between the Mediterranean Sea and the Atlantic Ocean have been well reported, our results indicate that part of the bluefin tuna population remains in the Mediterranean basin for much of the year, revealing a more complex population structure. In this study we demonstrate links between the western Mediterranean, the Adriatic and the Gulf of Sidra (Libya) using over 4336 recorded days of location and behavior data from tagged bluefin tuna with a maximum track length of 394 days. We described the oceanographic preferences and horizontal behaviors during the spawning season for 4 adult bluefin tuna. We also analyzed the time series data that reveals the vertical behavior of one pop-up satellite tag recovered, which was attached to a 43.9 kg tuna. This fish displayed a unique diving pattern within 16 days of the spawning season, suggesting a use of the thermocline as a thermoregulatory mechanism compatible with spawning. The results obtained hereby confirm that the Mediterranean is clearly an important habitat for this species, not only as spawning ground, but also as an overwintering foraging ground.
