摘要：

Spawning of razorback suckers, Xyrauchen texanus, in Lake Mohave occurred from 10-22°C and larvae were collected at water temperatures from 10-15°C in 1982 and 1983. In the laboratory, hatching success was similar from 12-20°C, but reduced hatching success was found at 10°C while none hatched a 8°C. Development rate and oxygen consumption were positively related to incubation temperature. Direct effects of ambient Lake Mohave water temperatures on hatching success of razorback sucker embryos are considered minimal. Historical spawning temperatures for the species are hypothesized based upon successful incubation temperatures and comparison to the white sucker, Catostomus commersoni. © 1990 Kluwer Academic Publishers.
