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.
