Trophic structure of the pelagic food web in the East China Sea.

The article discusses a study on bottom-up processes that might be controlling the trophic structure of the East China Sea. Topics covered include the regulation of phytoplankton, zooplankton and larval fish abundance, transfer efficiency indicated by the biomass ratio of zooplankton and phytoplankton, temperature's co-action with resource availability in the determination of trophic structure, and decrease in the zooplankton-phytoplankton biomass ratio with increasing phosphate concentration.
