some evidence is presented to show that the first transfer coefficient
(primary to secondary production) may be less than 10%. We have no
information on the second transfer coefficient, except that Steele (1965)
suggested that it was high in temperate waters. Perhaps the nearest
approach to the truth is 75 million tons (0.09.0.136).
