We assessed first winter habitat use by placing wild rainbow trout Oncorhynchus mykiss (52–155 mm total length) in wire-mesh enclosures with different cover treatments and at varying fish densities. Cobble–boulders substrates (20–40 cm diameter

We used caged fish with a cobble – boulder substrate to test the effect of fish size on first-winter survival of rainbow trout, Oncorhynchus mykiss, to compare survival of rainbow trout and brook trout, Salvelinus fontinalis, and to test for a temp

The behaviour of wild underyearling rainbow trout Oncorhynchus mykiss in concealment habitat in a laboratory stream aquarium at 2 and 6°C was recorded daily with an infrared video camera for 90 min over dawn. Aggressive behaviours (threat nips, nips

The proportion of rainbow trout (Oncorhynchus mykiss) concealing themselves in simulated interstitial spaces was examined in the presence of surface ice, in turbid water, and in clear water. Tests were conducted in enclosures in a small Idaho stream

Submersed aquatic plants that are abundant in some stream reaches have a potential to provide winter concealment cover for juvenile salmonids. We monitored an index of macrophyte abundance in a portion of the Henrys Fork of the Snake River during two

This study examined the relationship between light intensity and the number of juvenile rainbow trout (Oncorhynchus mykiss) visible to a snorkeler during February in the Henrys Fork of the Snake River, Idaho, USA. Fish were concealed in the substratu

To evaluate their first-winter survival, wild rainbow trout Oncorhynchus mykiss (78–169 mm total length) were placed in small wire-mesh cages at four sites along a thermal gradient in the Henrys Fork of the Snake River in October 1989. Four cages a

During February-April 1990 the number of age-0 cutthroat trout Oncorhynchus clarki and brown trout Salrno trutta concealed during the day in several types of cover was assessed in a large river, the South Fork of the Snake River in southeastern Idaho

We assessed changes in density, distribution, and microhabitat of age-0 rainbow trout (Oncorhynchus mykiss) in Silver Creek, a partially spring-fed stream, by periodic snorkeling in August 1987 through January 1988. We examined trout stomach contents

Underwater observers counted juvenile salmonids in study areas on mid-Columbia River tributaries, and the accuracy of these counts was examined. We compared counts taken by two to six experienced snorkelers with counts obtained after use of sodium cy
