Resultats del tercer any de l\u2019estudi per a con\u00e8ixer l\u2019estat de contaminaci\u00f3 marina amb la tortuga marina com a bioindicador<\/strong><\/p>\n

Durant l\u2019any 2021 han estat ateses un total de 90 tortugues babaues (Caretta caretta) des de l\u2019\u00c0rea de Cl\u00ednic i Rescat de la Fundaci\u00f3 CRAM. D\u2019aquestes, s\u2019han obtingut un total de 58 mostres, entre femtes i contingut digestiu, apareixent pl\u00e0stic a nivell macrosc\u00f2pic en el 89,7% de les mostres analitzades.<\/p>\n

Gr\u00e0cies al gran volum de tortugues marines i a la implicaci\u00f3 i inter\u00e8s en la conservaci\u00f3 marina, la Fundaci\u00f3 CRAM obt\u00e9 una informaci\u00f3 molt valuosa sobre l\u2019estat de contaminaci\u00f3 del mar. \u00c9s per aix\u00f2 que ens trobem en el tercer any d\u2019estudi de l\u2019an\u00e0lisis de la pres\u00e8ncia de pl\u00e0stic a les tortugues marines que arriben al CRAM: s\u2019analitzen les seves femtes, el contingut digestiu en el cas de les necr\u00f2psies i el n\u00famero d\u2019animals que arriben entortolligats amb brossa marina. Tot amb la finalitat d\u2019estudiar el contingut de macropl\u00e0stic que tenen i diferenciar-lo en diferents categories. Amb aquesta informaci\u00f3 podem con\u00e8ixer m\u00e9s sobre la contaminaci\u00f3 que existeix en el mar i ajudar a reduir-la.<\/p>\n<\/div>

Cal destacar que les tortugues marines tendeixen a ingerir restes de pl\u00e0stic o quedar-se entortolligades, tenen una gran distribuci\u00f3 espacial i utilitzen tots els compartiments marins (des del fons fins a la superf\u00edcie), el que les converteix en un gran bioindicador de l\u2019estat de contaminaci\u00f3 dels mars i oceans.<\/p>\n

Durant l\u2019any 2021, s\u2019ha analitzat un total de 52 mostres de femtes de tortuga marina i en el 90,4% d\u2019aquestes han aparegut restes de pl\u00e0stic, sent el m\u00e9s habitual el tipus l\u00e0mina (33%), seguit de fragments pl\u00e0stics (14%) i de pl\u00e0stic tipus foam (7%).<\/p>\n

De les 6 necr\u00f2psies de tortugues marines realitzades en el 2021, s\u2019han trobat restes de pl\u00e0stic en 5 d\u2019elles. El c\u00famul de pl\u00e0stics en el tracte digestiu no va ser la causa de la mort d\u2019aquests individus, per\u00f2 en diferents casos si que va produir enteritis severa, el que produeix dolor, anor\u00e8xia i compromet immunol\u00f2gicament a l\u2019animal. Aquest fet podria ser la causa que siguin m\u00e9s susceptibles a amenaces, principalment ser capturades de forma accidental per arrossegament, suposant un problema per a la seva salut i conservaci\u00f3.<\/p>\n

Tamb\u00e9 han estat ateses 6 tortugues marines amb aletes entortolligades en xarxes o fils de pesca, sent necess\u00e0ria l\u2019amputaci\u00f3 en 4 casos. Una de les tortugues tamb\u00e9 presentava un ham al seu interior. El n\u00famero d\u2019animals amb restes de xarxes est\u00e0 augmentant anualment, sent el 2021 l\u2019any que m\u00e9s han aparegut des de l\u2019inici de l\u2019estudi, podent ser a causa d\u2019un augment de pesca il\u00b7legal i de xarxes fantasma al Mediterrani.<\/p>\n

\u00c9s fonamental que, en el cas de trobar-nos un animal entortolligat, mai s\u2019ha de retirar el material causant de l\u2019entortolligament, i s\u2019ha de trucar immediatament al 112 per procurar una assist\u00e8ncia veterin\u00e0ria que augmenti les possibilitats de recuperaci\u00f3 de l\u2019animal.<\/p>\n

\u00c9s important destacar que la troballa de pl\u00e0stics a l\u2019interior de les tortugues marines t\u00e9 una import\u00e0ncia a diferents nivells: el pl\u00e0stic en si com a contaminant, el pl\u00e0stic actuant com a esponja qu\u00edmica davant de subst\u00e0ncies nocives per a la salut com podria ser el mercuri i que trobar aquesta quantitat de pl\u00e0stics a l\u2019interior de les tortugues marines indica que el mar cont\u00e9 una gran quantitat d\u2019aquests residus, i aix\u00f2 no nom\u00e9s influeix a la vida marina, sin\u00f3 a la vida de tots els habitants del planeta, ja sigui per consum de productes de mar com pel cicle de l\u2019aigua.<\/p>\n<\/div>
