One hundred specimens of unicorn leatherjacket, Aluterus monoceros purchased from markets of municipalities of Niterói and Rio de Janeiro from May to August 2006. The fishes were measured, necropsied, fileted and analysed their organs. Sixteen fishes were parasitized by nematode Anisakidae: Anisakis spp. and Contracaecum sp. with respectively, 1 and 16% of prevalence, 2 and 3.31 of mean intensity, and 0.02 and 0.53 of mean abundance. Two larvae of Anisakis sp. were found in mesentery of one fish and Contracaecum sp. was found in liver and mesentery with 1 to 9 specimens of range of infection. Fifty-one fishes were parasitized on the liver and mesentery by metacestodes of Trypanorhyncha. The collected species were Floriceps saccatus and Callitetrarhynchus speciosus with respectively, 45 and 6% of prevalence, 3.17 and 2.83 of mean intensity, and 1.43 and 0.06 of mean abundance, the range of infection by F. saccatus was 1 to 20 and by C. speciosus was 1 to 5. Anisakis sp. and these two species of Trypanothyncha were reported in A. monoceros for the first time.
2006年5月至8月，从尼泰罗伊市和里约热内卢市的市场购买了100份单角革鲀（Aluterus monoceros）标本。对这些鱼进行了测量、剖检、切片，并分析了它们的器官。16条鱼被线虫异尖科（Anisakidae）寄生：异尖线虫属（Anisakis spp.）和对盲囊线虫属（Contracaecum sp.），感染率分别为1%和16%，平均强度分别为2和3.31，平均丰度分别为0.02和0.53。在一条鱼的肠系膜中发现了2条异尖线虫属幼虫，在肝脏和肠系膜中发现了对盲囊线虫属，感染范围为1至9个标本。51条鱼的肝脏和肠系膜被锥吻绦虫的中绦期幼虫寄生。采集到的种类为囊形扁头绦虫（Floriceps saccatus）和华丽四吻绦虫（Callitetrarhynchus speciosus），感染率分别为45%和6%，平均强度分别为3.17和2.83，平均丰度分别为1.43和0.06，囊形扁头绦虫的感染范围为1至20，华丽四吻绦虫的感染范围为1至5。异尖线虫属和这两种锥吻绦虫首次在单角革鲀中被报道。
