Many Web sites that advise consumers on the fish species that they should eat (because they are harvested in a sustainable manner) recommend against buying orange roughy ( Hoplostethus atlanticus). Hilborn et al. (2006) challenged this interpretation and showed that orange roughy were being harvested very near to maximum sustained yield and were not being overfished. Discuss this controversy and explain the principles you would use to define a stock that was overharvested.
