The scars of bottom trawling are still visible on seamounts in Chile’s Juan Fernández Archipelago, even 25 years after the fishing practice took place in the area, according to a new study. In 2024, scientists from Chile and the U.S. used remotely operated vehicles aboard the Schmidt Ocean Institute’s research vessel R/V Falkor to survey four seamounts, underwater mountains that rise up from the seafloor, off Chile’s coast. Three of the seamounts are located in the Juan Fernández Archipelago, a cluster of volcanic islands that has one of the highest known rates of marine endemism on the planet. An estimated 62% of the reef fish species of Juan Fernández and the neighboring Desventuradas Islands are found nowhere else in the world. Other unique endemic species include the Juan Fernández fur seal (Arctocephalus philippii) and the Juan Fernández rock lobster (Jasus frontalis).  The fourth study site was the Solito Seamount, located north of the Juan Fernández Archipelago and known to harbor similar marine communities. In the late 1990s and early 2000s, fishers conducted bottom trawling on the Juan Fernández seamounts, dragging weighted nets across the seafloor to catch orange roughy (Hoplostethus atlanticus) and alfonsino (Beryx decadactylus), long-living, deep-sea fish. After catches dwindled, these fisheries collapsed and the trawling stopped. Later, in 2015, Chile permanently banned bottom trawling on all of its seamounts. At Solito, by contrast, the study, published in July in Deep Sea Research, found no evidence that bottom trawling had ever occurred. Twenty-five years after bottom trawling had taken…This article was originally published on Mongabay

Thirteen beluga whales, part of a pod of about 30 that were left languishing in a shuttered Canadian theme park, arrived in the U.S. The first transfer of six whales happened on July 21, and another seven were shipped out on August 3. These whales are part of the emergency transfers from Canada’s Marineland to their new homes in the U.S., marking the beginning of the end to a year-long saga of uncertainty. Shipped in specialized, cold-water containers, the belugas (Delphinapterus leucas) traveled for hours, on trucks and a plane, to two U.S. facilities: nine individuals went to SeaWorld in San Antonio, Texas, and four females to Shedd Aquarium in Chicago, Illinois, in two batches. Marine mammal veterinarians accompanied the cetaceans throughout their journeys, according to a press release from Georgia Aquarium. A spokesperson from the Atlanta-based aquarium said in an email it hopes to receive two beluga whales from Marineland in subsequent transfers. The international transfer came to fruition after several aquariums, all accredited with the U.S.-based Association of Zoos and Aquariums (AZA), drew up an emergency rescue plan earlier this year to transfer the belugas out of Marineland. These cetaceans had spent years at the theme park in Niagara Falls, Ontario. In 2019, Canada passed the landmark Ending the Captivity of Whales and Dolphins Act, which banned the keeping, breeding and trading of cetaceans — whales, dolphins and porpoises — for entertainment, affecting Marineland’s business model. By 2021, Marineland was Canada’s only entertainment park with cetaceans and was…This article was originally published on Mongabay
