PNAS, 112, 13934-13939. The data used give species/population values of the following parameters:- K: Bertalanffy growth coefficient; m inf: Maximum body mass; water temperatures: T_Kelvin is the temperature we used. Some other descriptors from FishBase are also included. See FishBase for definitions of parameters and the units in which they are measured.
