Two species of Lernaeocera are present in the southeastern North Sea. Lernaeocera lusci infects bib Trisopterus luscus, dragonet Callionymus lyra and sand goby Pomatoschistus minutas. L. minuta is a junior synonym of L. lusci. The second valid species, L. branchialis, infects whiting Merlangius merlangus. The two species can be morphologically separated by the antennary processes, which are present in L. lusci and absent in L. branchialis. Discriminant functions allow complete separation between L. lusci and L. branchialis. There is high intraspecific, host-dependent variability within L. lusci. Length of L. lusci is significantly influenced by host size, and body form is influenced by the site of attachment of L. lusci on at least one host (bib). It is suggested that L. lusci consists of 3 forms: f. lusci, f. minuta and f. lyra.
在北海东南部存在两种鱼虱属物种。卢氏鱼虱感染无须鳕Trisopterus luscus、小绵鳚Callionymus lyra和沙虾虎鱼Pomatoschistus minutas。小型鱼虱是卢氏鱼虱的次异名。第二个有效物种，鳃鱼虱，感染欧洲银鲈Merlangius merlangus。这两个物种可以通过触角突在形态上区分开来，触角突在卢氏鱼虱中存在而在鳃鱼虱中不存在。判别函数可以完全区分卢氏鱼虱和鳃鱼虱。在卢氏鱼虱中存在高度的种内、宿主依赖性变异性。卢氏鱼虱的长度受宿主大小的显著影响，并且身体形态至少在一种宿主（无须鳕）上受卢氏鱼虱附着部位的影响。有人提出卢氏鱼虱由3种形态组成：卢氏形态、小型形态和小绵鳚形态。
