Salmon Conservation

The sound way to protect salmon
and safely deter predators.

Protecting salmon and ecosystems

A new approach to salmon conversation in oceans and rivers

Seals and sea lions (collectively known as pinnipeds) play a large role in our marine and aquatic ecosystems, acting as predator and prey for various species. Though populations were once severely depleted due to human impact, numbers seem to have increased in the past two decades. Given that these animals are sheltered under the Marine Mammal Protection Act (MMPA), negative interactions between humans and pinnipeds are avoided whenever possible. However, this becomes challenging in instances where pinnipeds predate on threatened/endangered fish populations, particularly at passage “bottlenecks” in riverine environments.

Using an auditory startle signal, Targeted Acoustic Startle Technology (TAST) can keep hunting seals away from human-created barriers to salmon migration, allowing a greater number of fish to reach their spawning grounds.
