Bio–ecology of Potamon algeriense (Herbst, 1785) (Crustacea, Decapoda) in eastern Morocco

espanolPara contribuir al conocimiento de la bioecologia de Potamon algeriense en Marruecos oriental y la cuenca hidrografica del rio Muluya, se estudiaron 90 estaciones entre 2013 y 2016, de las que solo 14 albergaban a esta especie, que se observo se encontraba limitada a los cursos de agua medio e inferior de la cuenca hidrografica del rio Muluya y mas concretamente a las zonas de Oued Za, Zegzel y el curso inferior de la subcuenca de la desembocadura del rio Muluya. Los resultados de los analisis estadisticos mostraron que los principales factores que influyen en la distribucion y la abundancia de Potamon algeriense fueron la temperatura, la BOD5 y la conductividad. EnglishTo contribute to the knowledge of Potamon algeriense bio–ecology in eastern Morocco and the Moulouya watershed, a total of 90 stations were surveyed between 2013 and 2016. Of these, only 14 stations (out of the 90 surveyed) were positive concerning the occurrence of this species, which was found to be limited to the middle and lower watercourses of the Moulouya watershed, and specifically to Oued Za, Zegzel and the lower watercourse of the sub–basin Mouth of the Moulouya. The results of the statistical analyses showed that the main factors influencing the distribution and abundance of Potamon algeriense were temperature, BOD5, and conductivity.
