On the southern coast of South Korea, dark-banded rockfish, sea bass, and red seabream are caught by single-line fishing. In particular, bass in Jeollanam-do region using gear with attached fishing hooks, such as long-line gear, live shrimp bait.

Interviews were conducted relevant parties determine preference for bait, results showed a greater shrimp. Further, an survey between these bait investigations once or twice month June October. total, amounts fish naturally 56 52, respectively.
