Note
Most of the studies on temporal changes in gelatinous predator biomass and production have been limited to only a few species (i.e. Aurelia aunta, Mnemiopsis spp., and Pleurobracha spp.). Because of thls, it is difficult to conclude how important gelatinous predators are worldwide. Therefore, a study of gelatinous predator standing stocks, growth, production rates, and possible regulating factors, was undertaken in Saanich Inlet, British Columbia, where a number of species of medusae and ctenophores are seasonally very abundant (Huntley & Hobson 1978, Mills 1982).
