The olfactory sacs of 488 specimens belonging to 18 species rajid and arhynchobatid skates from the Argentine Sea were sampled for parasites. No parasitic copepods found in 11 host species, but siphonostomatoid referable Kroeyerina Wilson, 1932 (Kroyeriidae) Brianella corniger 1915 (Lernaeopodidae) on spotback skate Atlantoraja castelnaui (Miranda Ribeiro, 1907), smallnose fanskate Sympterygia bonapartii Müller & Henle, 1841, bignose acuta Garman, 1877 zipper sand Psammobatis extenta...
The use of parasites as biological tags allowed the identification three stocks Argentine hake Merluccius hubbsi in south‐west Atlantic. A total 344 fish caught Argentine‐Uruguayan Common Fishing Zone, San Matías Gulf, Jorge Gulf and Patagonian Shelf, were examined for 26 species found. Univariate analysis on both parasite populations infracommunity descriptors, well a discriminant analysis, separate stocks, one composed from second by third comprising samples Shelf. Northern characterized...
Three stocks of the Brazilian flathead Percophis brasiliensis were identified on coast Argentina and Uruguay using parasites as biological tags. A total 177 fish examined 23 parasite species found. Fish caught in four zones: north Argentine–Uruguayan Common Fishing Zone (34°30′–36°30′ S; 53°30′–56°00′ W), south (38°08′ S 57°32′ El Rincón zone (39–41° 60–62° W) San Matías Gulf (41°40′–42°10′ 63°50′–65°00′ W). Discriminant analyses allowed identification three discrete zones (86·44% classified...
Traditionally, parasitology has been concerned with the harmful effects of parasitic organisms; it is basically an applied science. Since its founding in field medicine, and later veterinary mainly devoted to generating knowledge, which applicable parasite control management, eventually their eradication. However, complexity parasitism, as revealed over recent decades by workers various specialisms parasitology, makes application management measures very difficult natural environments. This...
Host phylogeny and ecological convergence are two factors thought to influence the structure of parasite communities. The aims this study were determine diversity metazoan parasites 10 sympatric fish species family Carangidae from southeastern Gulf California, analyze their similarity at infracommunity component community levels, in order if host species, particularly those congeneric with similar characteristics, exhibit assemblages parasites. In total, 874 specimens examined 40 identified....
Four stocks of Argentine anchovy Engraulis anchoita in the south‐west Atlantic, south 34°S were identified by use parasites as biological tags. A total 671 fish examined for and 19 parasite species found 664 anchovies. The populations both infra‐ component communities showed marked latitudinal gradients. Cluster analyses allowed identification four groups, one composed autumn samples (35–37°S) three spring ones. Among latter, a Patagonian group (43–46°S) was clearly separated from Bonaerense...
Two stocks of striped weakfish Cynoscion guatucupa in the south‐west Atlantic Ocean, were identified using parasites as biological tags. A total 297 fish caught Brazil, Uruguay and Argentina, contained 29 species metazoan parasites. Univariate analysis on parasite populations, well multivariate discriminant analysis, calculated for juvenile adult separately, allowed identification two stocks, one from Argentina other to be made. Southern samples characterized by higher prevalences abundance...
In order to identify the best tools for stock assessment studies using fish parasites as biological indicators, different host traits (size, mass and age their interaction with sex) were evaluated descriptors of cumulative patterns both parasite abundance infracommunity species richness. The effect such variables was analysed a sample 265 specimens Percophis brasiliensis caught in Argentine Sea. abundances richness modelled generalized linear mixed models ( GLMMs ) negative binomial Poisson...
Hysterothylacium aduncum (Rudolphi, 1802) is reported from five fishes and one invertebrate species. Third-stage larvae were found in the crustacean Themisto gaudichaudii mesenteries of Engraulis anchoita Merluccius hubbsi; fourth-stage recovered digestive tract M. hubbsi Scomber japonicus adult specimens obtained stomach intestine hubbsi, S. japonicus, Genypterus blacodes brasiliensis. Nematodes are described, measured illustrated. Parasitic prevalence, mean intensity range calculated...
We assessed temporal variability in parasite infections of rough scad (Trachurus lathami) 3 samples from Miramar (MI) 2008, separated by periods 1 mo, and 2 Villa Gesell (VG), each 2008 2009 (Buenos Aires Province, Argentina), respectively. A sample was also obtained Cabo Frio (CF) (Brazil) to compare differences communities between fish this locality Argentinean locality. All were parasitized at least 27 species. Similarity-based multivariate analysis revealed significant localities, but...
SUMMARY Patterns of infection among hosts in a population are often driven by intrinsic host features such as age or sex, well positive negative interactions between parasite species. We investigated helminth parasitism 2 South American rodent species, Ctenomys australis and C. talarum (Octodontidae), to determine whether the unusual solitary subterranean nature these would impact their patterns infection. applied generalized linear models data on total 7 species (1 6 ). Host season capture...
