A fisherman does much the same thing anywhere, but the body of water in which he fishes makes a difference. On the Nile River, Egyptian fishermen might go out on a raft or canoe with a net or in a larger boat with a large net. They could use spears to harpoon fish, trap fish in baskets, or use hooks and lines.
The Instructions of Khety has this to say about the life of a fisherman in ancient Egypt:
"I mention for you also the fisherman. He is more miserable than one of any other profession, one who is at his work in a river infested with crocodiles. When the totalling of his account is made for him, then he will lament. One did not tell him that a crocodile was standing there, and fear has now blinded him. When he comes to the flowing water, so he falls as through the might of God."
