is one piece episode 41 filler?

Arlong offers not to kill the citizens of Cocoyasi Village if Nami surrenders, only killing the crew. Nami decides to refuse this offer, joining the battle even at the expense of the townspeople.

Meanwhile, Nojiko successfully revives Luffy, but most of his body remains trapped underwater. While Sanji dives underwater to break the cement trapping Luffy, Zoro battles Arlong, attempting to break his saw nose he claims is indestructible.

Usopp also appears, announcing his victory against Chew.
