Natural, biodegradable compositions are described as well as methods for their manufacture. Fishing lures and other items made of the biodegradable materials disintegrate over time in fresh or salt water to reduce pollution. The materials are digestable by fish and other aquatic animals, reducing potential harm to the animal from ingesting a fishing lure or other item made from the natural biodegradable materials disclosed. Because the material is digestable, it can also be used as a food source or supplement for fish and aquatic animals.
