Amb els alumnes de primer de l\u2019ESO<\/b> vam rec\u00f3rrer les aig\u00fces del riu Bes\u00f2s<\/u> per descobrir la vida del riu<\/u>.<\/p>\n

Vam explorar la riera de Martinet<\/u>, a la cap\u00e7alera de riu, i vam trobar un bosc de ribera ben conservat, amb aig\u00fces netes i fresques. Vam capturar cuques de capsa<\/i>, perles.<\/i> Ef\u00edmeres <\/i>i barretines<\/i> (Figura 1<\/b>) que s\u00f3n molt sensibles a la contaminaci\u00f3, cosa que ens indicava que el riu estava ben conservat i sense contaminar. (Foto 1<\/b>)<\/p>\n

Vam continuar riu avall pel riu Congost<\/u>, prop de Granollers. El Congost no tenia bosc de ribera, la seva llera era plena de c\u00f2dols arrodonits i l\u2019aigua for\u00e7a transparent. A l\u2019aigua hi vam trobar sabaters<\/i>, una sangonera<\/i>, un cranc de riu americ\u00e0 <\/i>(<\/i>Figura 1<\/b>). Aquests organismes ens indicaven que les aig\u00fces ja estaven una mica contaminades, i tot l\u2019entorn alterat per construccions. (Foto 2<\/b>)<\/p>\n

Finalment vam acabar a la desembocadura del Bes\u00f2s,<\/u> a Sant Adri\u00e0 del Bes\u00f2s, a l\u2019aiguabarreig amb el Mediterrani. No cal dir que el tram final del riu est\u00e0 canalitzat i envoltat de construccions,que s\u2019hi aboquen les aig\u00fces de refrigeraci\u00f3 de la t\u00e8rmica, i aix\u00f2 ens indica que el riu est\u00e0 molt alterat i les aig\u00fces no s\u00f3n de bona qualitat. Tot i amb aix\u00f2 vam veure carpes<\/i> nedant, i un bernat pescaire<\/i> que feia goig de veure. (Foto 3<\/b>)<\/p>\n

Vam tenir un bon dia per fer de naturalistes, tot i que ens vam quedar amb les ganes de c\u00f3rrer per la sorra de la platja i fer-nos un bon bany !!<\/p>\n
