00:00The Blue Shadow of the Mediterranean. A scenario of extinction.
00:05Welcome to a report that takes us deep into the heart of an urgent ecological crisis.
00:11Today, we focus our attention on one of the ocean's most graceful inhabitants,
00:16the blue shark prionus Glauca.
00:19Although globally categorized as near-threatened,
00:22its fate in the Mediterranean Sea has taken a dramatic turn.
00:26Reaching the status of critically endangered in the area between the Gulf of Lyon and Malta.
00:33The heart of the crisis.
00:34The blue shark, easily recognizable by its brilliant blue color and long pectoral fins,
00:41faces a dual threat.
00:43First, those fins are highly sought after in the shark fin trade.
00:48Second, fishing for this species in the Mediterranean is currently unregulated.
00:52The situation for Chandritchians, or Keralaginous fishes, is dire in this basin,
00:58which harbors the highest percentage of threatened species in the world,
01:02an alarming 53%.
01:04A population on the edge to understand the magnitude of the problem.
01:10Scientists and recreational fishermen turned citizen scientists,
01:14joined forces to collect genetic data in the Gulf of Lyon and the Ligurian Sea.
01:19The result of this study has sounded the alarm.
01:23The vast majority of the sharks observed were juveniles.
01:27Specimens between 1.2 and 2 meters were recorded,
01:31equivalent to sharks approximately 2 to 5 years old.
01:35This data is crucial and worrying.
01:38It means the observed sharks are too young or are just reaching the age of sexual maturity.
01:43This raises two disturbing conclusions.
01:47Either the reproductive populations are minimal, right,
01:50or they are maturing at smaller sizes,
01:53possibly due to the limited space or food scarcity in the Mediterranean.
01:58Understanding this juvenile dynamic is the key to the species' survival in these waters.
02:03In sufficient efforts, the blue shark crisis has crossed borders.
02:07In November 2022, the species was included in Sites Appendix 2 to regulate its trade.
02:14A year later, the International Commission for the Conservation of Atlantic Tunas, ICCAT,
02:21agreed to a 23% reduction in catch quotas in the North Atlantic.
02:26However, in the Mediterranean and beyond, a crucial battle remains lost.
02:31The obligation to land sharks with their fins naturally attached to vital measure
02:36against illegal trade remains unresolved after more than 15 years of debate.
02:43The story of the blue shark in the Mediterranean is a stark reminder
02:46that, despite international progress,
02:50much work still needs to be done to protect this vital and vulnerable traveler
02:54before its blue shadow disappears forever from our waters.
