Un ph\u00e9nom\u00e8ne inhabituel a r\u00e9cemment \u00e9t\u00e9 observ\u00e9 au large des c\u00f4tes de Monastir : des poissons ont \u00e9t\u00e9 retrouv\u00e9s morts en grande quantit\u00e9, tandis que la mer a pris par endroits une teinte rouge\u00e2tre. Selon la chercheuse au sein de l\u2019Institut national des sciences et technologies de la mer, Dr Afef Fattahlli, cette situation r\u00e9sulte d\u2019une prolif\u00e9ration anormale de microalgues.<\/p>\n

Invit\u00e9e sur les ondes de la radio nationale\u00a0, la scientifique a expliqu\u00e9 que ces algues microscopiques consomment d\u2019importantes quantit\u00e9s d\u2019oxyg\u00e8ne dissous dans l\u2019eau, provoquant un appauvrissement en oxyg\u00e8ne et l\u2019asphyxie des poissons. Ces derniers, une fois morts, deviennent impropres \u00e0 la consommation.<\/p>\n

Les relev\u00e9s effectu\u00e9s par satellite ont permis de constater une hausse notable de la temp\u00e9rature de l\u2019eau dans la r\u00e9gion au cours de la m\u00eame p\u00e9riode, accompagn\u00e9e d\u2019un changement dans les courants marins qui se sont orient\u00e9s vers le littoral au lieu de se diriger vers le large. Ce ph\u00e9nom\u00e8ne a favoris\u00e9 la stagnation de l\u2019eau, emp\u00eachant son renouvellement et cr\u00e9ant un environnement propice \u00e0 la multiplication des algues.<\/p>\n

Le minist\u00e8re de l\u2019Agriculture a confirm\u00e9, dans un communiqu\u00e9 officiel publi\u00e9 le 21 juin, la pr\u00e9sence d\u2019une \u00ab mar\u00e9e rouge \u00bb entre les villes de Khnis et de T\u00e9boulba, ainsi que la mort de nombreuses esp\u00e8ces marines. Les autorit\u00e9s appellent les habitants et les p\u00eacheurs \u00e0 la prudence, en \u00e9vitant de p\u00eacher, consommer ou vendre des poissons morts ou d\u2019origine incertaine, notamment ceux \u00e9chappant aux circuits de distribution soumis au contr\u00f4le v\u00e9t\u00e9rinaire.<\/p>\n

De son c\u00f4t\u00e9, l\u2019Instance nationale de s\u00e9curit\u00e9 sanitaire des produits alimentaires a \u00e9mis une alerte similaire. Elle recommande aux citoyens de n\u2019acheter du poisson que dans les points de vente l\u00e9gaux, en rappelant les risques sanitaires li\u00e9s \u00e0 la consommation de produits contamin\u00e9s.<\/p>\n

L\u2019Institut national des sciences de la mer assure suivre de pr\u00e8s l\u2019\u00e9volution de la situation sur les c\u00f4tes tunisiennes et se tient pr\u00eat \u00e0 intervenir en cas de besoin.<\/p>\n","protected":false},"excerpt":{"rendered":"
