Not only the size of a fish can sustain a big predator, but abundance can as 
well-- among the subspecies of the Brown Bears (Ursus arctos), the Kodiak 
subspecies  U. arctos middendorfi run larger than the inland races because 
the plentitude of salmon makes a much bigger contribution to their protein 
intake....
