This study focused on the relationship between catch diversity of set net fishery and discards based on the relationship between the amount of landings, species diversity, and the amount of discards. The data used in the analysis represent the daily total landing and total discards from set nets operated in Taiji Bay, southern part of Kumano-nada (33°36´N, 135°58´E) during the 1998 and 2001 fishing periods. The results suggest that the amount of discards decreased with increase in the landings.
