<p>Sport fishing has become popular, and a practice of so-called catch and release has become common in which a fish that has been caught is released at the place where it was caught. When exercising such a practice, care should be taken to avoid damage to the caught fish. Barbless hooks have been invented for that purpose, which have no barbs in the hook tip, but with barbless hooks fishing failure often occurs.</p><p>[Solution]</p><p>For solving this problem, according to the invention grooves 3 are formed at a position 2 near the hook tip 1 where normally barbs are provided. This can meet the contradictory needs of avoiding damage to a caught fish and avoiding fishing failure.
