How to say "barb" in Japanese

• 羽枝うし
  nounThe technical term for a barb of a feather, one of the slender branches of the vane. This is a specialized ornithological word, not everyday vocabulary for 'barb' in other senses.
• 触鬚しょくしゅ
  nounPrimarily means a barbel or palp — a whisker-like sensory appendage near an animal's mouth. As a rendering of 'barb' it applies only to such feeler structures and is seldom the word you want otherwise.
• 顎あごJLPT N1approx.Common
  nounA common word meaning chin or jaw, also used for the barb of a fishhook, the pointed part that keeps the fish from slipping off. Choose this for fishing contexts.

Use 顎 for the barb of a fishhook; 羽枝 is the technical barb of a feather; 触鬚 really means barbel or palp, so it suits 'barb' only in that whisker-like sense.
