    • Gajardo, Pedro; Peña-Torres, Julio; Ramírez Cabrera, Héctor (WILEY-BLACKWELL, 2011-05)
      P>In the case of small pelagic fish, it seems reasonable to consider harvest functions depending nonlinearly on fishing effort and fish stock. Indeed, empirical evidence about these fish species suggests that marginal catch ...
    • Brahm, R.; Hartman, J. D.; Jordan, A.; Díaz, M. (IOP Publishing Ltd, 2018)
