| Research Abstract |
The hook selectivity of longline fishing for red tilefish was elucidated. The appropriate hook size for both of the sustainable fishing and resources management is presumed as J#15 for Tainawa-bari hook.
Red tilefish from several Japanese costs, East China sea and Taiwan coast are presented as a same population. The whole population, not only the local area population, should be considered for resources management.
