Eleginops maclovinus, a potential species for the diversification of the aquaculture in Chile, has been reported as a natural host of Caligus rogercresseyi, a parasite that severely affects salmon grown in sea cages in southern Chile, and also as an important host for Lepeophtheirus mugiloidis. In order to contribute to the biological knowledge of L. mugiloidis, adult lice were collected from infested E. maclovinus in the field to compare with the life cycle of C. rogercresseyi. The study showed that the life cycle of L. mugiloidis was similar to the life cycle recently reported for L. salmonis, comprising eight stages of development, with only two chalimus stages, differing from C. rogercresseyi which has four chalimus stages and does not present preadult stages. L. mugiloidis reached the adult stage at 467ºD, while C. rogercresseyi reached the adult stage at 382ºD. The average size of females of L. mugiloidis was 44% larger than males, different from C. rogercresseyi, where females were 13.4% larger than males in samples collected from the field and 9.9% in samples produced under laboratory conditions.

Lepeophtheirus mugiloidis 和 Caligus rogercresseyi 生命周期受控条件下的比较，巴塔哥尼亚 blenny Eleginops maclovinus 的寄生虫

Eleginops maclovinus是智利水产养殖多样化的潜在物种，据报道它是Caligus rogercresseyi的天然宿主，这是一种严重影响智利南部海网箱中生长的鲑鱼的寄生虫，也是Lepeophtheirus mugiloidis的重要宿主。为了有助于L的生物学知识。mugiloidis，成人虱子从患病收集ê。maclovinus在该领域与C的生命周期进行比较。罗杰克雷塞伊。研究表明，L的生命周期。粘液菌与最近报道的L生命周期相似。鲑鱼，包括八个发育阶段，只有两个 chalimus 阶段，与C不同。rogercresseyi有四个 chalimus 阶段，不存在成年前阶段。升。mugiloidis在467ºD达到成虫阶段，而C . rogercresseyi在382ºD达到成年阶段。L的雌性的平均大小。mugiloidis比雄性大 44%，与C不同。罗杰克雷塞伊，其中在从田间采集的样本中，雌性比雄性大 13.4%，在实验室条件下产生的样本中为 9.9%。
