"He hadn't fought at all." In this line of the poem, the reason this fish didn't put up a fight is because there was no more fight left in him. This fish was caught many times, and escaped every time. After a certain number of times being caught, there was no more effort to struggle and break free from another hook, so the fish simply stopped trying. There was no challenge in catching this fish.
