Minecraft wiki entry for Survival_in_an_infinite_desert, associated text: As sticks can be collected from dead bushes and string is dropped by spiders, you could use a village crafting table to craft a fishing rod, giving you a sustainable food source (using water from wells or river biomes and repairing or replacing rods with anvils/grindstones/crafting tables). However, this is likely unnecessary as village farms provide better food anyway.
