Abstract

The extensive construction works of container terminals progressed since 2006 was converted to small scaled construction works or reclaiming works since 2012 in Busan New Port area. To investigate changes in activity of otters with the change of construction work scales, the linear densities of spraints at 15 localities of 5 areas (I-V) near the Busan New Port construction areas were surveyed during the period from 2012 to 2016. As the results, the average linear density of spraints has a tendency to increase since 2014. That is, the linear densities of spraints have increased at the area II and IV where the reclaiming works have been progressed, although have decreased or unchanged in the areas I, III and V where small scaled construction works have been progressed. Based on the fact that there were habitats at the Honamdo in the area II and the Yeondo in the area IV, otters seemed to restore their activities around the habitats as the center regardless of the reclaiming works.
