Dolphins Encountered in Kepulauan Seribu
Abstract: Kepulauan Seribu has
been considered as one of the dolphin migration routes. This is based on the
number of reports from fishermen and communities in Kepulauan Seribu on the
existence of cetacean. The purpose of this study was to assess the type,
behavior, deployment location, and estimate the number of dolphins found in
Kepulauan Seribu. th th nd thResearch was conducted on May 10 to May 27 , 2010 and 22 June to 3
July 2010. Observations were made every day, except Friday, and started
at 7:00 a.m. to 6:00 pm. Observation by boat was used in the research.
Observation of the amount, type, and behavior of cetacean had been done
visually. Based on research results, it can be concluded that the
species of dolphins
found in Kepulauan
Seribu are Delphinus
delphis, Pseudorca crassidens,
Stenella longirostris, and Tursiops truncatus, with a total number of
145 individuals. Species of dolphins are most often found is T. truncatus,
whereas the least common type is Delphinus delphis. In addition there are also
calf and unidentified species. The location of the encounter with the dolphins
most often occurs around Pulau Gosong Congkak (Karang Congkak) and Karang
Lebar. Judging from the observed behavior, it can be said that Kepulauan Seribu
is a foraging area and migration routes for cetacean. In addition, Kepulauan
Seribu was also considered as nursery ground for calf.
