Shark Bay, the bay below Dixon's Farm in Swallows and Amazons is where the Swallows go fishing from Swallow. Mr Dixon gives John some worms and tells him there are lots of perch between here and his landing-place, but that they would do better with minnows.
They catch fourteen perch, but when Roger hooks another one it is attacked by a huge pike when he is hauling it in. Roger asks I say, do you think its really safe to bathe in this place? They catch no more as the pike has frightened them off, so they stop, and Susan fries their catch. The name Dixon’s Bay is given up, and they call the bay Shark Bay after Roger’s great fish (SA7).
