| Summary: | Salmon farming is one of the pillars of the Chilean economy but due the emerging of many diseases, including the ecto-parasitism caused by Caligus rogercresseyi, the salmon industry has decreased their production indices. Based on that, alternative rearing systems are being evaluated for salmon cultivation, one of them fish farming in deep water, where the temperature is lower than the temperature of the surface, as C. rogercresseyi is a parasite whose life cycle is water temperature dependent. This paper describes the biological behaviour of the parasite and the effect of deep water and culture temperature on the establishment of the parasite in the host. La salmonicultura constituye uno de los pilares de la economía chilena, pero debido al desarrollo de innumerables enfermedades, entre las que destaca la ectoparasitosis causada por Caligus rogercresseyi, los productores de salmón han disminuido sus índices productivos. Debido a esto, se están buscando sistemas alternos para cultivar salmones, siendo uno de ellos el cultivo de peces en aguas profundas, donde la temperatura es menor a la temperatura de la superficie, ya que C. rogercresseyi es un parásito cuyo ciclo de vida es dependiente de la temperatura del agua. El estudio detalla el comportamiento biológico del parásito y el efecto de la profundidad y temperatura de cultivo sobre el establecimiento del parásito en el hospedero. |
