Note

The daily ration and predation impact of medusae and ctenophores in the upper 25 m of Saanich Inlet were determined using data from gut contents analyses, digestion times, and predator/prey densities. The weight-specific dailyrations of the 3 major gelatinous predators (Pleurobrachia bachei, Phialidium gregarium, and Phialidium lomae) were a negative power function of their biomass. Small predators obtained a ration much in excess of maintenance needs, while the largest specimens had little excess carbon growth or reproduction.
