Tennessee Valley Authority Recommends Curtains of Bubbles to Mitigate Asian Carp

he Tennessee Valley Authority (TVA) recommended in their final programmatic environmental assessment to install what’s called a bio-acoustic fish fence (BAFF) that includes sound signals, directional strobe lighting, and a bubble curtain in order to keep the invasive species of Asian carp from Tennessee rivers.

According to the assessment, the species “has the potential to threaten native ecosystems, rare and protected species, sports fisheries, and public safety, which can lead to reduced recreation, tourism, and property values; and ultimately impact local economies.”

The TVA notes in their detailed report that there are are four fish that fall into the Asian carp family; the bighead carp, the silver carp, the black carp, and the grass carp. The species was introduced to America in the 1960s and 1970s. The fish were imported to improve the water quality in fish farms, and after they were utilized for other aquaculture purposes were allowed to be released into the Mississippi River.

Speaker-Elect Glen Casada Will Dive Into Solutions for Problem of Invasive Asian Carp In Tennessee Rivers

Speaker-Elect Glen Casada will convene an open forum this week to discuss the invasive Asian carp problem in Tennessee waters, according to a press release. The forum, scheduled for Thursday, December 20 at 12:45 p.m., will include several current and newly elected State Representatives who will attend the forum along with current TWRA Commission Chair Kurt Holbert as well as other TWRA officials and experts. According to the Tennessee Wildlife Resource Agency (TWRA), there are four species of Asian carp, originating in China, now in Tennessee and throughout the United States. The carp, brought to the U.S. for aquaculture purposes as far back as the 1970s, escaped into the delta areas of the Mississippi River during extreme floods in the late 80’s and early 90’s. While all four species of Asian carp can impact fish and other aquatic life in a number of ways, TWRAs most immediate concern is for the safety of boaters. Some species of carp are known for jumping when encountered by a boat. When they jump, the carp colliding with a passenger can cause serious injury. A number and variety of efforts are underway to control the spread not only in Tennessee, but nationwide. While controlling…
