Fishers in the east Indonesian Maluku Islands say rough seas are keeping them ashore and shrinking their catches as El Niño builds, according to early local monitoring and interviews. Yustinus Pesireron, a 64-year-old fisherman from Kaibobo village on Seram island in Maluku, told Mongabay on Oct. 2 he had not been to sea for almost a month — the longest break of his three decades on the water. He said fishing is the main source of income in the village of about 1,800 people. Yustinus said the earnings he makes from selling his catch finance daily household needs and school expenses for three of his six children. Local monitoring by partners of the UK-headquartered conservation group Blue Ventures shows the amount of fish caught on an average fishing trip in coastal waters around Ambon and Seram islands fell to an average of 3.6 kilograms (7.9 pounds) in April-July 2026 at one monitoring site, down from 8.3 kg (18.3 lb) in 2025 and 10.6 kg (23.4 lb) in 2024. The group said the data do not show that fish populations are shrinking. Rather, fishers report that higher waves and rougher seas are limiting how long they can fish and how far they can travel. “Sometimes, even when the weather isn’t good, we still go out to sea and catch some fish,” Yustinus told Mongabay in a phone interview. “But, as we say here in Maluku, such a catch is only enough to cover the cost of fuel, and perhaps food.

Two critically endangered Sumatran rhinos are pregnant at an Indonesian sanctuary, a rare success for a species reduced to a few dozen animals in the wild. The pregnancies also highlight the genetic constraints facing the country’s captive-breeding program. Indonesia’s Ministry of Forestry and the NGO Yayasan Badak Indonesia (YABI), which manages the sanctuary, announced the pregnancies on Oct. 3. A female named Ratu is carrying her fourth calf, fathered by Andalas, while her daughter Delilah is carrying her second calf, fathered by Harapan. Both are due around May 2027. Ratu was captured from the wild in Sumatra in 2005, while Andalas and Harapan, who are full brothers, were born at Cincinnati Zoo in the U.S. in 2001 and 2007, respectively. Delilah was born to Ratu and Andalas at the Sumatran Rhino Sanctuary in 2016 — meaning the father of Delilah’s calf is her paternal uncle. Experts at the Sumatran Rhino Sanctuary seek to pair the least-related males and females possible, Nina Fascione, executive director of the International Rhino Foundation, told Mongabay in an email. They also must consider factors such as differences in body size, she said, but their choices are limited by the small number of rhinos under human care. The 11 animals in Indonesia’s breeding program are the only captive Sumatran rhinos in the world, and all of the males in the program are related. “The current critical situation outweighs the genetic diversity considerations,” Fascione said. Ratu, a captive female Sumatran rhino, is expecting her fourth calf. Image…This article was originally published on Mongabay

Wildfires in West Kalimantan, Indonesia, are leaving wildlife without fresh water as ponds turn brackish and forest pools dry up, driving animals into villages and toward the coast. Residents and conservation groups are responding by providing water, rescuing affected animals and treating them as smoke and fires continue to affect their habitat. Preliminary findings by NGO Yayasan Planet Indonesia recorded at least 16 dead animals, including silvered langurs (Trachypithecus cristatus), long-tailed macaques (Macaca fascicularis) and proboscis monkeys (Nasalis larvatus, an endangered primate found only on Borneo), from early August through late September amid an intense fire season in coastal Kubu Raya, a district in West Kalimantan. That compares to 13 dead non-fish animals recorded during nearly six years of SMART patrols — a system for monitoring wildlife and threats in the forest — in the area, from September 2020 through June 2026, with most deaths attributed to natural causes or left unexplained. As freshwater pools dried up and village ponds turned brackish, Planet Indonesia found dehydrated wildlife moving closer to homes and the coast in search of water. “We have never had findings like this before,” said Adam Miller, co-founder of Planet Indonesia, in a statement sent to Mongabay. The NGO has worked alongside the village institutions in Kubu Raya since 2017. “When the mangroves lose their fresh water, the animals die,” Miller said.
