La situation est alarmante pour les p\u00eacheurs du sud de la France. Du fait des bouleversements climatiques, la taille des sardines ne fait que diminuer.<\/h2>\n

\"1024px-Sardines_-_\u9c2f(\u3044\u308f\u3057)\"<\/a>Selon une \u00e9tude financ\u00e9e par France Fili\u00e8re P\u00eache<\/strong>, la taille des sardines et des anchois p\u00each\u00e9s dans le sud de la France ne ferait que diminuer. Ces deux esp\u00e8ces, parmi les poissons les plus p\u00each\u00e9s en M\u00e9diterran\u00e9e<\/strong>, auraient vu leur taille se r\u00e9duire consid\u00e9rablement l\u2019an dernier, passant de 15 \u00e0 11cm<\/strong> en ce qui concerne les sardines.<\/p>\n

De fait, la biomasse des sardines pr\u00e9sente dans cette mer du sud a \u00e9galement, elle-aussi, fortement diminu\u00e9, passant de 200\u00a0000 \u00e0 67\u00a0000 tonnes<\/strong> en l\u2019espace de dix ans. Et cela alors que leur nombre n\u2019a pas diminu\u00e9, ce qui explique ind\u00e9niablement une r\u00e9duction de leur taille. Du c\u00f4t\u00e9 des anchois, c\u2019est le m\u00eame son de cloche.<\/p>\n

Plusieurs explications viennent corroborer ce ph\u00e9nom\u00e8ne. Tout d\u2019abord, la pr\u00e9sence d\u2019agents \u00e9trangers, parfois toxiques<\/strong>, qui a un impact direct sur la croissance et le d\u00e9veloppement des poissons. Mais la pr\u00e9sence de ces produits a \u00e9galement un impact sur la taille du plancton<\/strong>, aval\u00e9 par ces poissons. Un cercle vicieux en somme.<\/p>\n

Un probl\u00e8me \u00e9cologique qui a une cons\u00e9quence directe sur l\u2019\u00e9conomie locale.<\/strong> Anchois et sardines repr\u00e9sentent plus de 50 % du poisson p\u00each\u00e9<\/strong> dans cette r\u00e9gion. Et avec des poissons plus petits, et plus maigres, les prix s\u2019effondrent.<\/p>\n
