A.T. Robertson Commentary Mark 6:41

"And he took the five loaves and the two fishes, and looking up to heaven, he blessed, and brake the loaves; and he gave to the disciples to set before them; and the two fishes divided he among them all." — Mark 6:41 (ASV)

Brake the loaves; and he gave to the disciples (κα απο των ιχθυων). Apparently the fishes were in excess of the twelve baskets full of broken pieces of bread. See on Mt 14:20 for discussion of κοφινος and σφυρις, the two kinds of baskets.
