Diel microhabitat use of age-0 bull trout in Indian Creek, Washington
Abstract – We studied diel microhabitat use at the focal point of age-0 bull trout, Salvelinus confluentus, in Indian Creek, Washington during mid-summer and fall of 1997. Microhabitat variables included water depth and velocity, distance from the stream bottom, habitat and refuge use, substrate ty...

Diel microhabitat use of age-0 bull trout in Indian Creek, Washington |
abstract |
Abstract – We studied diel microhabitat use at the focal point of age-0 bull trout, Salvelinus confluentus, in Indian Creek, Washington during mid-summer and fall of 1997. Microhabitat variables included water depth and velocity, distance from the stream bottom, habitat and refuge use, substrate type, and substrate embeddedness. Age-0 fish were located over fines and gravel substrates in shallow, low-velocity water near stream margins, but were located in shallower water at night. Bull trout were highly associated with loose substrate, and used the substrate interstices for refuge cover. Diurnal bull trout counts decreased and no age-0 fish were observed after 15 September at water temperatures below 6.1 °C. Nocturnal counts remained relatively constant throughout the study. Our results suggest that age-0 bull trout surveys be conducted at night when summer water temperatures begin to decline. |

Microhabitat variables included water depth and velocity, distance from the stream bottom, habitat and refuge use, substrate type, and substrate embeddedness. Age-0 fish were located over fines and gravel substrates in shallow, low-velocity water near stream margins, but were located in shallower water at night. Bull trout were highly associated with loose substrate, and used the substrate interstices for refuge cover. Diurnal bull trout counts decreased and no age-0 fish were observed after 15 September at water temperatures below 6.1 °C. Nocturnal counts remained relatively constant throughout the study. Our results suggest that age-0 bull trout surveys be conducted at night when summer water temperatures begin to decline.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2003</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2003||||||||||</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">bull trout</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">James, P.
