S Immediately after sampling was done on the Gunnison River below Morrow Point Reservoir in August 1973, mackinaw trout (SaZveZinus namay- cush) fingerlings were captured; they had been stocked 2 mo earlier in the reservoir's inlet area. The reservoir, since impoundment in 1968, had been receiving heavy stocking of kokanee salmon (Oncorhynchus nerka) and comparatively light stocking of mackinaw trout in an attempt to stunt the kokanee to supply prey for the mackinaw. Some fishermen at Morrow Point also reported taking some coho salmon (Oncorhynchus kisutch) which had been stocked in the Gunnison drainage above Blue Mesa Reservoir in the 1969-1972 period. However, gillnet sampling in the reservoir in 1973 caught no coho salmon and showed that the game fish abundance was as follows: rainbow trout (SaZmo gairdneri)>brown trout (SaZmo trutta)> kokanee>brook trout (SaZvelinus fontinaZis)>mackinaw trout =cutthroat trout (SaZmo cZarki). Kokanee salmon spawners averaged 20 in. Further- more, in a 2-hr period in December 1973 an average of one 0+ kokanee salmon was observed every 27 sec moving downstream in the tailwaters below Blue Mesa Dam into Morrow Point Reservoir. Many of the kokanee salmon were in distress, unable to swim and sound properly. On one day in December 1974, distressed 0+ kokanee salmon averaging 4.3 in. were so abundant in the swirl area of the Blue Mesa tailwaters that one small minnow seine haul captured 1,219 salmon. The 1973 findings prompted a temporary discontinuance of stocking in Morrow Point Reservoir and raised the question as to whether the rainbow trout in Morrow Point were primarily migrants from tributaries or migrants from Blue Mesa Reservoir. It also opened speculation as to whether the apparently greater numbers of rainbow trout in the river below the Curecanti dams were being provided by catchables being stocked in the
