No. of bitstreams: 1 200781.pdf: 2703929 bytes, checksum: d2ee131d8ae3372359b424e0732625b4 (MD5) Previous issue date: 1975 / Análise qualitativa e quantitativa dos helmintos que se encontravam infestando, 65peixes das espécies Scomberomorus cavalla (Cuvier) e 65 de Scomberomorus maculatus (MitChill) na costa do Ceará. Foi observado que entre as duas espécies hospedeiras, a ca­vala foi a que apresentou maior Índice de parasitismo.Não foi comprovada qualquer influência do mês do ano, sexo ou idade do hospedeiro, na taxa de infestação helmíntiba. O grupo de helminto que mostrou o maior índice de infestação, foi o de nematódeo, representado 90,01% dos vermes da cavala e 86,34% da serra. Os helmintos encontravam-se em todos os Órgãos dos peixes, principalmente no estômago, onde eles se encontravam em maior número e mais frequentemente. Conclui-se que o termo “marca biológica”, seja aplica­do ao conjunto de parasitas que apresentaram maior lindice de infestação e não para cada espécie isoladamente. / ln this paper the author presents qualitative and quantitative analysis of the helminths parasites of Scomberomorus cavalla (Cuv.) e Scomberomorus maculatus (Mitch.) in Ceará Coast. Based on earlier on the host species in Ceará, the author adds biological data also refering to these species. It is shown through tables and graphics the helminths with the highest infestation frequency as well as the most infected parts. Of the hosts samples, Scomberomorus cavalla (Cuv.) presented the highest parasite índex. The infestation proved not to be due to the month of the yeat the samples were captured, age or sex of the hosts. The group which showed the highes·t infestation level in both host species, was composed by the nematodes, represented by 90,01% of helminths recovered from king mackerel and 86,34% from spanish mackerel. The helminths were recovered from all the parts of the body, mainly from the stomach, where they appered in great number and higher frequency. Prosohynchus atlanticus manther, 1940 and Rhadinorhynchus prsitis (Rudolphi, 1802), 1911 are fereded for the first time in Brazil. The conclusion suggests that the designation "biological tags" should be applied to the recovered helminths as a whole and not to a single species.
