Occurrence of Discocotyle sagittata on Sea Trout

  author={D. Slinn},
Discocotyle sagittata Leuckart is a well-known mono-genetic trematodo found on the gills of European sal-monids1–3. So far as I am aware it has previously only been found on hosts caught in fresh water, and it is therefore of interest to record it from sea trout (Salmo trutta L.) caught in the sea. 
The population dynamics of the monogenean gill parasite Discocotyle sagittata Leuckart on Windermere trout, Salmo trutta, L.
The British host, the brown trout, has been intensively studied for many years and it was thought that this would be of advantage in attempting to relate any seasonal fluctuations in the parasite population to the biology of the host. Expand
Microhabitat selection of Discocotyle sagittata (Monogenea: Polyopisthocotylea) in farmed rainbow trout.
Evidence of equivalent site selection taking place in fishes maintained under conditions promoting continuous reinfection in aquaculture is provided, since a significant inverse association was found between the intensity of mature parasites and their proportion on anteriormost gill arch I. Expand
Sexual differences in the incidence and severity of ectoparasitic infestation of the brown trout, Salmo trutta L.
Hatchery-reared and wild brown trout, Salmo trutta L., were examined for skin ectoparasites during their spawning period in 1977 and 1978 and a total of eight genera of parasites were identified with as many as five different genera occurring on a single fish. Expand
The occurrence of Diplozoon paradoxum Nordmann, 1832 (Trematoda: Mongenea) in certain waters of northern England and its distribution on the gills of certain Cyprinidae.

Diplozoon paradoxum is randomly distributed on the gills, sides of the gill apparatus, hemibranchs and surfaces of primary lamellae of G. gobio, P. phoxinus and R. rutilus, and predominates in rivers rather than in ponds or reservoirs. Expand
A checklist of British and Irish freshwater fish parasites with notes on their distribution
The parasite fauna of Britain appears to be considerably poorer in number of species than that of mainland Europe, and that of Ireland poorer still. Expand
The parasite fauna of resident char Salvelinus alpinus from Arctic islands, with special reference to Bear Island
It is concluded that the parasite fauna of char on offshore Arctic islands does not agree well with the predictions of island biogeographical theory. Expand
Evidence of complement-mediated killing of Discocotyle sagittata (Platyhelminthes, Monogenea) oncomiracidia.
Discocotyle sagittata oncomiracidia were rapidly killed when incubated in naïve plasma and immune sera from both rainbow trout and brown trout, indicating that complement acting via the alternative pathway is responsible for the parasiticidal effect observed. Expand
Stable isotopes, elemental distribution, and growth rings of belemnopsid belemnite rostra: Proxies for belemnite life habitat
Abstract Stables isotopes and elemental composition of two well-preserved belemnite rostra (Hibolithes beyrichi and H. hastatus) from the Bathonian of central Poland were studied. AverageExpand


The attachment of the monogenean Discocotyle sagittata Leuckart to the gills of Salmo trutta L.
The monogenetic trematode Discocotyle sagittata attaches itself to the gills of Salmo trutta with its long axis inclined to the long axis of the primary lamella to which it is attached, the directionExpand
The life history and bionomics of Diclidophora denticulata (Trematoda: Monogenea).
Age resistance is probably developed to the extent that larvae cannot establish themselves on older fish and is probably due to mechanical difficulties and changed habits of the host. Expand
