Reasons for marine mammals stranding on Indonesian beaches being studied

Jakarta – The Ministry of Marine Affairs and Fisheries (KKP) in cooperation with several institutions and marine experts, is performing a study on reasons for mass stranding of marine mammals on Indonesian beaches.

” This is done to prepare for that a similar occurrence (such as stranding of lots of pilot whales on Madura Island) will not occur once again in the future,” the ministry’s Director General of Marine Area Management Tb Haeru Rahayu said in a statement here on Sunday.

The study is in accordance with a direction of Marine Affairs and Fisheries Minister Sakti Wahyu Trenggono to maintain marine animals for the well-being of the country and future generations.

Marine mammals are threatened animals which have been given security status nationally and worldwide.

Indonesian waters are one of the migration paths for marine mammals such as whales, dolphins, and dugong on the planet. Of the existing 90 types of marine mammals in the world, 35 of them are found in Indonesia.

” One of the risks to marine mammals in Indonesia is marine mammals that strand themselves on Indonesian beaches time to time,” he stated.

Data of the ministry’s Directorate of Conservation and Marine Biodiversity (KKHL) reveal that there were 103 marine mammals stranded themselves in 2015, 255 in 2016, 143 in 2017, 154 in 2018, 142 in 2019, and 107 in 2020.

This year, during the January-February duration, 66 marine mammals were found stranded. They consisted of 52 pilot whales that stranded themselves on Patereman beach, Modung, Bangkalan, Madura Island, East Java, recently.

He discussed that speed and accuracy in handling every stranded life event is very important and has a significant influence on the security of these marine biota.

” Understanding the causes of stranding marine mammals is really essential for future management. I invite experts from Unair (Surabaya-based Airlangga University), IPB (Bogor Farming University), WSI (Whale Stranding Indonesia), RASI (Uncommon Marine Types Indonesia), and Flying Vet to discuss this phenomenon,” he discussed.

RASI Preservation Foundation biologist Danielle Kreb stated efforts to expose the existence of marine mammals are very crucial for the balance of marine environments, as marine mammals offer a really essential ecological contribution to the ecosystem in the world and people who use or relate to these biota.

On The Other Hand, Whale Stranding Indonesia (WSI) scientist Putu Lisa Mustika stated that in basic there are 11 causes of stranded marine mammals, particularly caught in low tide, disease, predation, noise, fishing activity, being hit by ships, marine contamination, seabed earthquakes, severe weather, algae flowering, and solar storms.

Meanwhile, IPB speaker Adriani Sunudin said the Madura Strait is a perfect protected environment for marine mammals. Based upon oceanographic data, at the time of the occurrence the water conditions tended to be cool due to the impact of extreme rain throughout Java, Sumatra, and Kalimantan, and with low salinity conditions.

Based upon the pathology technique, Unair researcher Bilqisthi Putra stated among causes of marine mammal deaths are emation, dehydration, sun scorched, and respiratory tension.
