Jeju's Indo-Pacific Bottlenose dolphin population in dangerThe National Fisheries Research & Development Institute recommends immediate action |
|
Measures to preserve Korea's Indo-Pacific Bottlenose dolphin population are urgently needed, according to a presentation given by the National Fisheries Research & Development Institute for members of the Jeju provincial government on March 24.
Until recently it was thought that only the common Bottlenose dolphin inhabited Korea. However, the National Fisheries Research & Development Institute's Whale Research Center said that according to research on Korean seas that was conducted from 2007 to 2010, it was found that Indo-Pacific Bottlenose dolphins also live in Korean waters, exclusively around Jeju Island.
The research involved distinguishing the types of dolphin by filming the animals’ dorsal fin. Ultimately it was deduced that about 110 Indo-Pacific Bottlenose dolphins inhabit the shores of Jeju.
This newly found dolphin population turned out to be the smallest of all Indo-Pacific Bottlenose dolphin populations in the world. Accordingly, the institute recommended preservation measures should be urgently prepared.
A typical Indo-Pacific Bottlenose dolphin population is normally composed of 200 or more animals.
The main reasons for the decrease in population numbers are fixed shore nets and dolphin shows, which have captured an estimated seven or eight dolphins. The Whale Research Center said that if this situation continues, the current population will be cut by half in 20 years and less than 20 dolphins would survive by 2060.
For more information, contact National Fisheries Research & Development Institute’s Whale Research Center, at 052-270-0911.
