Quick Summary

Recent whale and whale shark deaths in Indonesia, including five incidents over three weeks, have raised concerns about a potential increase in strandings. A study from 2025 shows an uptick from fewer than ten annual cases between 2011 and 2019 to more than twenty-two since 2020. Experts attribute this rise to factors like oceanographic changes and increased smartphone reporting, rather than a genuine increase in strandings.

Story summary

Since September 12, five whale and whale shark deaths have occurred within a three-week period along the coasts of Indonesia. These incidents include a dead whale shark on Bali, another dead whale shark in South Sulawesi, a decomposed whale carcass in mangroves of Riau province, and a stranded whale that died in West Java. Another whale shark became stranded and died on a beach in Aceh province just days later.

A 2025 study published in Scientific Reports by the Elasmobranch Institute Indonesia and Konservasi Indonesia observed an increase from fewer than 10 whale shark strandings per year between 2011 to 2019 to more than 22 cases a year starting from 2020. Researchers link these strandings to seasonal changes, oceanographic conditions such as sea-surface temperatures and wave height, as well as marine productivity influenced by upwelling processes that draw feeding marine life closer to the coastlines. However, experts also note an increase in smartphone use and social media reporting which might contribute significantly to perceived increases in stranding incidents.

Narrative

Published in Scientific Reports, the study linked strandings to seasonal and oceanographic conditions – including sea-surface temperatures, wave height and marine productivity – particularly in areas affected by seasonal upwelling, an oceanic process where wind-driven currents pull cold, nutrient-rich deep water to the surface, drawing feeding marine life closer to coastlines.
