| 概要 |
Seasonal variations in caught fish by gill net and benthos at the places near the artificial reefs (Sta.B-1) and 200m from the artificial reef (Sta.B-2) were observed 4 times a year of 2010. The numbe...r of species and individuals of caught fish at Sta.B-1 is larger than those at Sta.B-2 throughout the year. The number of species and individuals, wet weight, and bio-diversity of benthos are larger at Sta.B-1 than those at Sta.B-2 throughout the year. Such results suggest that the suitable human interaction (construction of artificial reef) increases the bio-diversity and bio-productivity in the coastal sea.続きを見る
