Abstract

Spawning of the razorback sucker, (Xyrauchen texanus), in Lake Mohave was assessed by visual surveys, trammel netting, and larval sampling in 1982 and 1983. Collections of ripe fish (n=546) and larvae (n=1,205) indicated that razorback suckers spawned from November to May, but larvae were collected only from spawning activity occurring from December through March. Water temperature was 13°C in November as spawning commenced, dropped to 9.5°C during January and February, then increased to 22°C as the spawning season ended in May. Peak spawning, indicated by ripeness, spawning activity, and larval collections, occurred from January through March when water temperatures ranged from 10 to 15°C.
