Abstract

Eastern Indonesia is known as the center of marine biodiversity of the world as well as habitat and marine mammal migration path. Not all marine mammal events in eastern Indonesia are well documented. The purpose of this study was to determine the occurrence of marine mammals in eastern Indonesia in 2016. Data collection done through observation, indepth interview with the community and experts. The results of this study were 8 (eight) occurrences of marine mammals which were in Mollucas, North Mollucas and West Papua Provinces with the highest incidence in August. That marine mammals were Duyung (Dugong dugon), Sperm Whale(Physetermacrocephalus), Risso’s Dolphin(Grampus griseus), and 2 types of unidentified Whales. The marine mammals exist were deliberately netted by people, stranded, trapped in fishing nets or deliberately commercialized. This marine mammals stranded occurence indicate the requirement of strategies development for handling these protected marine ‘biota’ to store their population.

Highlights

Indonesiahas a variety of species of Cetacea but few records related to its spread, especially from remote areas[1]
There are 8 stranded marine mammal in Mollucas, North Mollucas, and West Papua involved 9 individual, 5 individual stranded, 2 individualdeliberately arrested, 1 individual using spectacle and 1 individual trapped in Um Island (Table 1)

Summary

Introduction

Indonesiahas a variety of species of Cetacea but few records related to its spread, especially from remote areas[1]. The spread of Cetacean in Indonesian waters has not been known for certain yet because research on Cetacean is still very rare[2]. Information on distribution, population size and behavior of cetaceans is not widely known to the world[3].BBird’s Head. Whales are known to migrate to breed in warmer tropical waters.Thedeepwater region of Mollucas is an important migration path for Whalesffrom the PacificcOceantto the Indian Oceann[5]. Marine mammals are protected under The Minister of Forestry and Environment
