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.

TLDR
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.

The population dynamics of the monogenean gill parasite Discocotyle sagittata Leuckart on Windermere trout, Salmo trutta, L.

TLDR
The population dynamics of a parasite of a freshwater fish, Discocotyle sagittata, was investigated because the biology of 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.

Emergence of Discocotyle sagittata (Monogenea: Polyopisthocotylea) in rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) in an Austrian aquarium

TLDR
The Museum Niederösterreich, Haus für Natur (St. Pölten, Lower Austria), features a large fish exhibition and, in one of the tanks, a portion of the rainbow trout died with no further investigations performed.

Microhabitat selection of Discocotyle sagittata (Monogenea: Polyopisthocotylea) in farmed rainbow trout.

TLDR
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.

Sexual differences in the incidence and severity of ectoparasitic infestation of the brown trout, Salmo trutta L.

TLDR
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.

The occurrence of Diplozoon paradoxum Nordmann, 1832 (Trematoda: Monogenea) in certain waters of northern England and its distribution on the gills of certain Cyprinidae

TLDR
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.

A checklist of British and Irish freshwater fish parasites with notes on their distribution

TLDR
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.

The parasite fauna of resident char Salvelinus alpinus from Arctic islands, with special reference to Bear Island

TLDR
It is concluded that the parasite fauna of char on offshore Arctic islands does not agree well with the predictions of island biogeographical theory.

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. Average

TLDR
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.
