It seemed that they had prepared a lot of stones just so they could deal with a lot of zombie fish.
Their accuracy is also passable, so they were able to deal with a lot of those fish.
Even though most of those fish certainly didn't die, they were also injured or knocked out, so they weren't jumping up to the ferry again.
Austin and Owen were obviously stronger than Bella and Violet, but the difference isn't obvious because they were dealing with the fish that were jumping out properly with almost the same accuracy.
They were properly dealing with those jumping fish, so the others were also able to concentrate on dealing with the zombie and mutant fishes in their areas.

However, when they were already halfway through the lake, the mutant fishes became more restless, and more of them tried jumping out of the water.
