Abstract Stream‐dwelling Brook Trout Salvelinus fontinalis rely heavily on terrestrial
invertebrates, especially when aquatic prey is limited. We examined the effects of an …

Dietary studies are essential for studying trophic dynamics, and are often based on analysis
of stomach contents. A popular method to collect stomach contents is the use of pulsed …

Forested headwater streams are dependent on their riparian zones for many critical goods
and services. It is assumed that riparian disturbance affects stream food webs, but for some …

Background. A sampling of stomach and intestine content is usually performed by dissection
of the gastrointestinal tract of fish. To avoid fish sacrificing, various non-lethal techniques …

Research on fishes sometimes requires that individual fish be captured and subjected to
invasive procedures multiple times over a relatively short time span. Electrofishing is one of …
