"One study, carried out around the Galápagos, found that squid from the genera Histioteuthis (62%), Ancistrocheirus (16%), and Octopoteuthis (7%) weighing between 12 and 650 grams (0.026 and 1.43 lb) were the most commonly taken ."

Some of those species are the ones most desired by humans: salmon, tuna, swordfish, bluefish, cod.
One sad note in this story is the rampant overfishing of menhaden, one of the main feeder fish for more desirable (for humans) fish. Menhaden is not eaten by people, except in some oil extracts, IINM. Mostly industrial uses -- fertilizer, etc.
Do you mean that sperm whales eat mainly the smaller squid? They don't have the baleen straining setup, how could they catch enough small ones to make it worth their while?
