Default Human-generated Sounds May Be Killing Fish

Human-generated Sounds May Be Killing Fish
ScienceDaily (Mar. 13, 2009) — Anthropogenic, or human generated, sounds have the potential to significantly affect the lives of aquatic animals - from the individual animal's well-being, right through to its reproduction, migration and even survival of the species.

According to a new study marine animals could suffer detrimental effects ranging from a loss of hearing to increased stressed levels as a result of environmental noise - in ways not dissimilar to humans and land animals. The study also describes some recent well-controlled experimental studies while highlighting areas for future study.

"Human generated sounds in the marine environment may result in only small shifts in behavior for some animals, but immediate death in others. With the vast increase in production of sound in the marine environment due to human activity such as oil exploration, shipping and construction, the effect of human-generated sounds on the aquatic life becomes a growing issue", said Dr. Arthur Popper from the University of Maryland, USA.

Marine animals use sounds to communicate and to glean information about their environment. Unlike the "visual scene" developed by the animal's sense of sight, the "auditory scene" derived from sounds provides marine animals with a three dimensional view of the world and extends far beyond the visual scene.

Where are these sounds coming from? The article was not clear on that. Interesting concept, fish don't like rap either?

Off shore drilling is one. Sonar is the worst and it has killed whales. Boat propellers would be another. Lots of noise pollution disrupting sea life.

Wish they could use that noise to kill Asian carp.

Dolphins can be made deaf by sonar, scientists find
Dolphins suffer temporary hearing loss from Navy sonar, scientists have found, suggesting military activity could be causing the animals to become stranded.

Dolphins can be made deaf by sonar, scientists find - Telegraph
excerpts from above:
Quote:
The animals, which communicate using a natural form of "sonar ping", are said to confused and frightened by the much louder man-made noise of military vessels.
Quote:
The paper, published in the Royal Society journal Biology Letters, read: "With several marine mammal strandings linked to naval sonar activities, concerns are rising about the effects of naval sonar on marine mammal physiology and behaviour. In controlled laboratory studies, we show that actual sonar pings can induce at least temporary hearing loss in dolphins."

LFA sonar systems generate intense noise capable of propagating across entire ocean basins. The court in NRDC v. Evans found it “indisputable that marine mammals, many of whom depend on sensitive hearing for essential activities like finding food and mates and avoiding predators, and some of whom are endangered species, will at a minimum be harassed by the extremely loud and far traveling LFA sonar.” Id. at 1188. Other marine species, including fish and sea turtles, have also been shown to be harmed by intense sonar. Understanding the great risks in allowing LFA training throughout the world’s oceans without sufficient environmental review and mitigation, the court held inadequate the Navy’s original EIS for this system and required that the Navy strengthen its mitigation and monitoring measures in order to protect marine wildlife.
