Salmon runs in B C are depleting — but some have the potential to come back, report shows

#114 of 158 articles from the Special Report: Food Insider Pink, chum and coho populations could all increase, the study found, if given the opportunity.

The report, released by the Salmon Coast Field station, a field research base and charity near Echo Bay, analyzed more than 150 salmon populations in the Broughton Archipelago and inlets on northeast Vancouver Island and the central coast. They assessed fish in 92 river systems for abundance and 24 for resilience, which is the salmon s ability to come back from low numbers.

Human noise pollution is harming ocean creatures

NationofChange Human noise pollution is harming ocean creatures Noise from vessels, sonar, seismic surveys and construction can damage marine animals hearing, change their behaviors and, in some cases, threaten their ability to survive. Humans are changing the way the ocean sounds, and it is having a profound impact on marine life. A major new literature review published in Science on Thursday found that noise from vessels, sonar, seismic surveys and construction can damage marine animals’ hearing, change their behaviors and, in some cases, threaten their ability to survive. “When people think of threats facing the ocean, we often think of climate change, plastics and overfishing,” Neil Hammerschlag, a University of Miami marine ecologist who was not involved with the paper, told The Associated Press. “But noise pollution is another essential thing we need to be monitoring.”

In the Oceans, the Volume Is Rising as Never Before

In the Oceans, the Volume Is Rising as Never Before A new review of the scientific literature confirms that anthropogenic noise is becoming unbearable for undersea life. Credit.Jon Han Published Feb. 4, 2021Updated Feb. 8, 2021 Although clown fish are conceived on coral reefs, they spend the first part of their lives as larvae drifting in the open ocean. The fish are not yet orange, striped or even capable of swimming. They are still plankton, a term that comes from the Greek word for “wanderer,” and wander they do, drifting at the mercy of the currents in an oceanic rumspringa. When the baby clown fish grow big enough to swim against the tide, they high-tail it home. The fish can’t see the reef, but they can hear its snapping, grunting, gurgling, popping and croaking. These noises make up the soundscape of a healthy reef, and larval fish rely on these soundscapes to find their way back to the reefs, where they will spend the rest of their lives that is, if they can hear
