Trophic efficiency between TL % PP to food chain
  70% 80% 90%
5% 2,322 2,655 2,985
10% 10,691 12,224 13,744
20% 57,054 64,148 71,299

Ecotroph fishes biomass estimates (millions of tons) between 40° N and 40° S as a function of the efficiency between trophic levels and the flux from PP to the first trophic level (TL).
