Evaluation of the temporal development of three introduced populations of brook trout, Salvelinus fontinalis, in Jizerské mountains, Czech Republic [PDF]
Three populations of brook trout, Salvelinus fontinalis, established in streams and reservoirs in the Jizerské Mountains, Czech Republic, were studied between 1995 and 2006. The maximum age was usually 3+ to 4+, but the age 7+ was also recorded.

Fishery-exteriors characteristics of the brooders of brown trout, rainbow trout and brook trout
This study aims to determine the reproductive indices of three types of salmon fish: brown trout (Salmo trutta morfa fario Linnaeus (1758), rainbow trout (Oncorhynchus mykiss Walbaum, 1792) and brook trout (Salvelinus fontinalis Mitchill, 1814) in ...

Do low-mercury terrestrial resources subsidize low-mercury growth of stream fish? Differences between species along a productivity gradient. [PDF]
Low productivity in aquatic ecosystems is associated with reduced individual growth of fish and increased concentrations of methylmercury (MeHg) in fish and their prey.

Specific niche characteristics facilitate the invasion of an alien fish invader in boreal streams [PDF]
We studied the ecological niche relations of native stream fish and an alien invader, brook trout (Salvelinus fontinalis), to examine if brook trout had located an underused environmental niche in our boreal study system. In both study years (1994 versus

Density-dependent regulation of brook trout population dynamics along a core-periphery distribution gradient in a central Appalachian watershed. [PDF]
Spatial population models predict strong density-dependence and relatively stable population dynamics near the core of a species' distribution with increasing variance and importance of density-independent processes operating towards the population ...

Host Switching of Zoonotic Broad Fish Tapeworm (Dibothriocephalus latus) to Salmonids, Patagonia [PDF]
Diphyllobothriosis is a reemerging zoonotic disease because of global trade and increased popularity of eating raw fish. We present molecular evidence of host switching of a human-infecting broad fish tapeworm, Dibothriocephalus latus, and use of ...
