ELS ESTURIONS (EL CAS DEL RIU EBRE)
Fernández J. V.
El riu Ebre era l'únic curs fluvial de l'àrea mediterrània ibèrica on vivia l'esturió, Acipenser sturio, peix arcaic i de dimensions grans que en l'actualitat es considera com una espècie en perill d'extinció. El llibre recull, en una compilació d'articles de diferents especialistes, dades històriques sobre la presència d'aquesta espècie al riu Ebre i la seva zona marina d'influència, i d'altres que avaluen el seu estatus actual, els motius que han provocat la seva desaparició i les possibilitats de reintroducció, a l'Ebre i als rius de la Península Ibèrica, d'Europa i d'Amèrica del Nord.
