able gametes in reach 10 (top) and in reaches 20-50
(bottom) ...............................................146
7.1. Relation of capture to tagging location for rainbow
trout, brown trout, brook trout, carp, flannelmouth
sucker, and humpback chub from the Colorado River and
tributaries 1984-86. D=downstream, U=upstream, N-none,
T-M=tributary to mainchannel, M-T=mainchannel to
tributary, T-T=tributary to tributary, WIT-within
tributary ..............................................157

rainbow trout from Colorado River 1984-86 ..............162

from the Colorado River in Glen and Grand canyons
during three sampling trips. DIM = diaptomid copepod
immatures; DAD = diaptomid adults; CIM = cyclopoid
copepod immatures; CAD = cyclopoid adults; HAR =

January 1985 ...........................................170
8.3. (Top) Frequency of occurrence of food groups from guts
of larval suckers (BHS=bluehead; FMS-flannelmouth)

Grand Canyon. (Bottom) Relative abundance of food
group items found in guts of larval suckers. Food
