Distribution patterns, mean intensity and prevalence of Lernaeocera lusci (Copepoda, Pennellidae) in its hosts Trisopterus luscus (Teleostei, Gadidae) and Merluccius merluccius (Teleostei Merlucciidae) were examined, together with parasitic abundance and aggregation in relation to the size of the host. The mean parasite abundance and variance to mean abundance ratio increased with host size, suggesting that the accumulation of this parasite had no noticeable impact on the structure of either host population. Merluccius merluccius being a newly colonized host in the Mediterranean, these results are discussed in relation to current ideas on the evolution of pathogenicity in heterospecific associations.
研究了卢氏鱼虱（桡足亚纲，鱼虱科）在其宿主欧洲无须鳕（硬骨鱼纲，鳕科）和无须鳕（硬骨鱼纲，无须鳕科）中的分布模式、平均感染强度和感染率，以及寄生虫丰度和聚集情况与宿主大小的关系。寄生虫平均丰度和平均丰度方差比随宿主大小增加，这表明这种寄生虫的积累对任何一个宿主种群的结构都没有显著影响。无须鳕是地中海新出现的宿主，结合当前关于异种关联中致病性进化的观点对这些结果进行了讨论。
