There are several synonyms for the term "cast hook" in fishing lingo. One common alternative is simply "fishing hook", which refers to any hook designed for use in catching fish. Another option for more targeted fishing is a "bait hook", which has a barb specifically designed to hold bait in place and entice fish. If you're after larger game fish, a "circle hook" might be the way to go - this type of hook is designed to lodge in the corner of a fish's mouth and prevent deep-hooking for safer catch-and-release fishing. Finally, a "treble hook" is a type of hook with three prongs that can be used for a variety of different fishing techniques.
