| the chemotherapy of monogeneans which parasitize fish: a review. | monogeneans which parasitize fish are still treated by bathing the fish in solutions of simple chemicals or staining dyes. in the early 1960s an insecticide, trichlorphon, replaced to a large extent the formerly used simple chemicals. its success was greater specificity against monogeneans and other ectoparasites, and to its great tolerance by the fish. the fact that the number of important monogenean species (i.e. pseudodactylogyrus anguillae, p. bini, gyrodactylus salaris) which cannot be trea ... | 1991 | 1937280 |

| the nutrition of the gill parasitic monogenean pseudodactylogyrus anguillae. | a histological and histochemical study of ingested food material, energy stores and enzymes in the monogenean pseudodactylogyrus anguillae, parasitizing the gills of the european eel (anguilla anguilla) is presented. it was found that mucus, epithelial cells and blood from the gills were ingested. glycogen deposits were small and primarily located in the parenchyma and to a minor extent in the vitellariae. numerous globules of neutral lipids were found in the vitellariae. a marked esterase activ ... | 1987 | 3422977 |
| on the distribution and abundance of eel parasites in nova scotia: influence of ph. | the geographic distribution of metazoan parasites of american eels (anguilla rostrata) was determined from 28 sites in the southern upland and adjacent regions of nova scotia. twelve parasite species were encountered. component community diversity as measured by species richness, shannon-wiener index (h') and hill's number (n1) decreased when ph < 5.4. seven species (azygia longa, crepidostomum brevivitellum, bothriocephalus claviceps, proteocephalus macrocephalus, paraquimperia tenerrima, echin ... | 1996 | 8636841 |
