In experiments run in an enclosed bay, we examined (i) the number of eggs that could be consumed by hungry sculpins of both species and various sizes within a 1-h feeding period and (ii) the potential number of eggs that could be consumed over the course of the major sockeye spawning period (7 days). The former provides an estimate of the number of eggs that could be eaten during a single spawning, and the latter provides an estimate of the overall effect of sculpin egg consumption on sockeye production
