Ejemplares no nativos<\/h2>\n

\u201cDif\u00edcilmente puedan progresar mucho m\u00e1s all\u00e1 de lo que es el sur de la cuenca del r\u00edo La Plata, porque m\u00e1s al norte, la temperatura del Paran\u00e1 hace que sea imposible para ellos sobrevivir\u201d, asegur\u00f3 un especialista.<\/p>\n

Pescadores comerciales y deportivos han capturado ejemplares no nativos en el Litoral argentino. Uno de los casos m\u00e1s sorprendentes es el del salm\u00f3n del Pac\u00edfico\u00a0(Oncorhynchus tshawytscha), el cual es originario de las regiones \u00e1rticas del hemisferio norte. Sebasti\u00e1n S\u00e1nchez, subdirector del Instituto de Ictiolog\u00eda del Nordeste dio detalles del tema.<\/p>\n

“En realidad la poca informaci\u00f3n que hay hasta ahora es que\u00a0estos animales han sido vistos en la parte del Paran\u00e1 Medio, en la parte inferior del Paran\u00e1 Medio, hacia la altura de Santa Fe, en Rosario<\/b>\u00a0aproximadamente”, se\u00f1al\u00f3.<\/p>\n

“No son tampoco muchos y posiblemente, como se menciona en alguna de esas notas, sean animales que\u00a0posiblemente han escapado de piscicultura<\/b>\u00a0o por haber sido transferidos a una zona que no es la zona original, digamos, donde nacieron y crecieron buscan encontrar alg\u00fan lugar para reproducirse”, indic\u00f3.<\/p>\n

“Un poco perdidos, llevados de manera por arrastre por alguna de las corrientes fr\u00edas que tenemos en el sur de nuestro pa\u00eds,\u00a0han llegado a encontrar de casualidad la desembocadura del r\u00edo de La Plata<\/b>. As\u00ed como algunos se pegan la vuelta al mar, otros se meten y en ese af\u00e1n de buscar alg\u00fan r\u00edo donde reproducirse, arriban un poco”, detall\u00f3.<\/p>\n

\"\"<\/figure>\n

Seg\u00fan mencion\u00f3 el cient\u00edfico, “dif\u00edcilmente puedan progresar mucho m\u00e1s all\u00e1 de lo que es el sur de la cuenca del r\u00edo La Plata, porque\u00a0el agua caliente es un problema ambiental importante para ese tipo de especies y a medida que nos vamos viniendo cada vez m\u00e1s al norte, la temperatura del Paran\u00e1, del Uruguay y de todos los r\u00edos se va haciendo cada vez m\u00e1s alta<\/b>\u00a0y es imposible para ellos sobrevivir en esas condiciones”.<\/p>\n

Los salm\u00f3nidos son del hemisferio norte y en Argentina fueron introducidos en el siglo pasado. “Ya hace muchos a\u00f1os, hay poblaciones que se est\u00e1n manteniendo porque se reproducen de manera natural todos los a\u00f1os en los r\u00edos de la Patagonia, en Tierra del Fuego, en el sur, inclusive hay un desarrollo de la pesca deportiva muy importante”, dijo.<\/p>\n

Seg\u00fan mencion\u00f3, son depredadores, vis\u00edvoros y en nuestro r\u00edo “posiblemente podr\u00edan llegar a impactar si estuvieran en un n\u00famero importante, pero este tipo de hallazgos espor\u00e1dicos seguramente no van a causar ning\u00fan tipo de impacto sobre las poblaciones, porque nunca van a ser m\u00e1s de unos pocos individuos”, complet\u00f3 en di\u00e1logo con Hoja de Ruta.
