Vaquita a rischio : In Cina è follia per la cocaina acquatica - Il giornale del mare
Skip to content (image: Frédérique Lucas)
La mania per la “cocaina acquatica” sta portando al collasso due specie animali tra cui il piccolo mammifero marino Vaquita (Phocoena sinus). Non è una droga, anzi. La cocaina acquatica, così l’hanno soprannominatai cinesi per l’alto costo (dai 2500 ai 10.000 dollari l’etto) nient’altro è che la vescica natatoria del pesce totoaba (Totoaba macdonaldi ) venduta essiccata come rimedio naturale o come alimento. La pesca eccessiva ed illegale del totoaba sta portando la specie al collasso e con essa anche la Vaquita o focena del golfo del Messico (un piccolo mammifero marino), che viene spesso rinvenuta tra le reti dei pescatori del totoaba. Il prodotto finito viene immesso nei mercati di Honk kong ma viene venduta anche via web. A dare l’allarme è la Environmental Investigation Agency (Eia) che in occasione del consiglio internazionale della CITES svolto a Ginevra ha riportato i dati degli ultimi studi.
Sui siti web e le TV cinesi, le vesciche natatorie di totoaba sono sbandierate come “il tesoro dei tesori” e accreditate con un’ampia varietà di qualità palliative: fermare l’emorragie, nutrire la carenza di yitamine, ripristinare la funzionalità epatica e renale e inumidire i polmoni secchi..
“Il prezzo delle vesciche natatorie totoaba”, dice Crystal Wang del gruppo di difesa WildAid , “è molto alto, di solito sopra le decine di migliaia di yuan cinesi”. A Hong Kong, si dice che un chilogrammo di vesciche natatorie di totoaba venga scambiato per 128.000 euro.
Il prodotto finito viene immesso nei mercati di Honk kong ma viene venduta anche via web. A dare l’allarme è la Environmental Investigation Agency (Eia) che in occasione del consiglio internazionale della CITES svolto a Ginevra ha riportato i dati degli ultimi studi. Il totoaba è un pesce endemico delle acque messicane dove vive anche l’ultima popolazione divaquita .Sembra che al mondo esistano meno di 30 esemplari di vaquita. Si stima che la specie possa scomparire prima del 2030. Entrambe le specie sono protette da leggi internazionali e la pesca del totoaba è vietata dal 1975.
