Sockeye salmon ground outside of Alaska. Illegal fishing in Kamchatka is subject to environmental concern. Sockeye is almost never farmed. A facility in Langley, BC harvested its first salmon in March 2013, and continues to harvest farmed salmon from its inland facility. United States sockeye salmon populations are currently listed under the US Endangered Species Act by the National Marine Fisheries Service as an endangered species in the Snake River and as a threatened species in Lake Ozette, Washington.

Robot fish the speed of swimming will increase. It exhibits a state of shock and confusion to the foreign object much like a real fish would. Robot fish record this type of behavior in advance. Military defense and marine protection are of rising concern in the research field. As missions become more complicated, high-performance Autonomous underwater vehicle (AUVs) become necessary. AUVs require fast propulsion and multidirectional maneuverability. Robotic fish are more competent than current AUVs propelled by motion because the fish is a paradigm of bio-inspired AUV. Like living fish, robot fish can operate in complex environments. They can not only perform
