Researchers study acoustic communication in deep-sea fish
Date:9/24/2008

RICHMOND, Va. (Sept. 24, 2008) An international research team studying sound production in deep-sea fishes has found that cusk-eels use several sets of muscles to produce sound that plays a prominent role in male mating calls.

These findings, published online today in the Royal Society journal, Biology Letters, may help researchers gain further insight into acoustic communication in the deep sea and the role of sound in fish behavior.

Virginia Commonwealth University Life Sciences biologists Michael L. Fine, Ph.D., Kim Nguyen and Hsung Lin, both graduate students at VCU, together with Eric Parmentier at the Universit de Lige in Belgium, examined the sonic muscles of the fawn cusk-eel, Lepophidium profundorum, a species found in the Atlantic Ocean.

"Little is known about acoustic communication in the deep sea because of the difficulties of observing fish in this habitat. Based on anatomy, ophidiid fishes, or cusk-eels, are likely one of the chief sound producers. They have unusual sonic muscles that occur in antagonistic pairs and are typically larger in males," said Fine, a professor in the VCU Department of Biology.

Many fish use an organ known as a swim bladder to produce sound. According to Fine, the fawn cusk-eel uses two muscle pairs to pivot a modified rib, 'the wing-like process,' forward. This action stretches the swim bladder. An antagonistic muscle pair then restores the swim bladder to its original position.

In previous work outside of the mating season, they found that the tiny intermediate muscle of the fawn cusk-eel was larger in females, which was quite surprising since male fish are usually more vocal than females, said Fine.

The research team obtained the fish during the summer mating season and found that intermediate muscle weight increased four fold and had become heavier in males than in females.

"Our findings suggest that the intermediate muscle likely assumes a pr
