Australian scientists have recorded a Murray cod named Arnie swimming a record 530 miles mostly upstream along a river system, highlighting significant fish migration and environmental health insights.
Scientists captured rare footage of the bumblebee catfish Rhyacoglanis paranensis climbing waterfalls in Brazil, revealing unique adhesion and movement behaviors that are crucial for understanding their migration and conservation needs amid habitat fragmentation.
Scientists captured rare footage of thousands of bumblebee catfish climbing a waterfall in Brazil, likely as part of a reproductive migration triggered by seasonal water level changes, highlighting the importance of preserving natural river habitats.
In the Netherlands, a live underwater camera feed allows viewers to ring a "fish doorbell" that signals workers to open a dam, aiding fish migration for spawning. The project, initially aimed at assisting fish, has unexpectedly gained international attention, with viewers eagerly participating in helping Dutch fish reach warmer waters.
California officials will spend $60 million to build a channel along the Yuba River to allow salmon and other threatened fish species to bypass a Gold Rush-era dam that has cut off their migration for over a century. The project is part of state and federal officials' efforts to reverse the environmental damage caused by century-old infrastructure along California's major rivers and streams. The dam blocks three species of fish from migrating up the river to spawn, and the National Marine Fisheries Service declared in 2012 that the dam posed a threat to the survival of those fish species.
