Researchers Work to Keep Rare Fish Off Endangered Species List

On the bank of the Little Tennessee River, downstream from the town of Franklin, biologists squeeze tiny yellow eggs from a fish into a plastic bag. Unlike caviar, these eggs won’t be eaten, but rather trucked to a high-tech aquatic lab in Knoxville, Tenn., to join an effort to keep a rare fish off the endangered species list.

The fish is a sicklefin redhorse, a recently discovered species found only in the western tip of North Carolina and a small bit of North Georgia. The extremely limited range of the animal and the precarious state of the streams where it lives raise questions about its long-term well-being, and whether it needs protection under the Endangered Species Act.

These eggs are part of a project to conserve the fish and expand its range, undertaken by the N.C. Wildlife Resources Commission, Eastern Band of Cherokee Indians, U.S. Fish & Wildlife Service, and Conservation Fisheries, Inc., a Knoxville-based non-profit specializing in the captive propagation and rearing of the region’s most imperiled fish.

“With the sicklefin redhorse, we have a chance to take some early conservation action and hopefully increase the size and number of spawning populations,” said Mark Cantrell of the U.S. Fish & Wildlife Service.

Biologists collected 27,000 eggs from seven different fish in this, the second year of the project. The eggs were taken to CFI’s Knoxville laboratory where they’ll be fertilized, hatch, and grow for about three months.

“No one has done this type of work with the sicklefin redhorse, so there is a steep learning curve,” said CFI’s Pat Rakes, commenting on the fact these fish have never been reared in captivity.

In the Tuckasegee River, spawning sicklefins swim from as far away as Fontana Reservoir. But instead of swimming well up the Tuckasegee River, they turn and swim up the Oconaluftee River, spawning below Ela Dam, and fueling a lot of speculation.

There is some thought the fish might imprint on a river, returning to that spot for spawning. With that in mind, Steve Fraley, a biologist with the N.C. Wildlife Resources Commission, hypothesizes that decades of pollution may have wiped out sicklefin that spawned in the Tuckasegee River, while those spawning in the cleaner Oconaluftee River would have survived, though the construction of Ela Dam cut short their migration.

Once the fish in CFI’s aquaria are about 1.5 inches long, about half will be moved to a hatchery operated by Cherokee Fisheries and Wildlife Management, in the Oconaluftee River watershed. From there, they’ll be released above Ela Dam, where biologists hope they’ll expand their range up into the Oconaluftee River. The remainder of the fish will be put in the Tuckasegee River, above Dillsboro Dam. The fish hatched this year will return to spawn in about 5 to 7 years, well after the scheduled removal of Dillsboro Dam.

CFI’s captive rearing has been supported with money from the Service, and next year a grant from the Cherokee Preservation Foundation will allow the Eastern Band of Cherokee Indians to hatch and rear eggs at their hatchery, an expanded role of a facility that has always produced trout.

The sicklefin is one of 15 redhorse species and was favored by native Americans who built extensive fish traps and weirs for this important source of protein. The sicklefin, which derives its name from its long, sickle-shaped dorsal fin, was first recognized as a distinct fish species by Roanoke College professor Robert Jenkins in 1992. Looking at various redhorse specimens, he noticed some specimens from the Little Tennessee River basin were different, and it became clear that instead of being an odd fit for other species, this was a new species, the sicklefin redhorse, which is also found in the Hiwassee River basin.

Growing to about a foot and a half long, sicklefins are bottom feeders, eating aquatic insects, though they will forage along downed logs, even turning upside down and eating along the log all the way to the water’s surface where one biologist has even heard them slurp.

Hunt for Imperiled Plant Leads to Little Tennessee River Discovery

In late May, a team of biologists canoeing the Little Tennessee River discovered two new patches of the federally-protected Virginia spiraea plant growing on the river’s banks.

The search was part of an effort to catalog where the rare plant is found along the river, and it also confirmed the plant’s continued presence at four spots where it was previously known to occur.

“Knowing where these plants are means we know where to focus our time and energy in conserving the species,” said Dennis Desmond, search organizer and land stewardship coordinator for the Land Trust for the Little Tennessee. “Of course, the ultimate goal is to recover them so they no longer need protection, and this was a tiny step toward that goal.”

The search brought together a host of organizations interested in both the conservation of the Little Tennessee River and Virginia spiraea, as biologists from the Land Trust for the Little Tennessee, Little Tennessee Watershed Association, Wilderness Society, Western North Carolina Alliance, Friends of the Greenway, USDA Forest Service, N.C. Natural Heritage Program, and two private citizens paddled canoes down the river, eyeing the banks for the flower’s tell-tale white flowers. The effort also garnered the support of a local business, as Jerry Anselmo of Great Smoky Mountain Fish Camp & Safari provided boats and shuttle services for the search.

The search was coordinated by the Land Trust for the Little Tennessee, a Franklin-based non-profit focusing on the conservation of the Little Tennessee River basin. This was one of two searches planned for this year, the next coming June 25th – both timed to take advantage of the plant’s showy, early-summer white blooms. This first float trip concentrated on the stretch of river below Emory Dam, while the second effort will concentrate on the stretch of river through the Needmore tract.

Virginia spiraea was listed as threatened by the U.S. Fish & Wildlife Service in 1990, and today it’s found in seven states across Appalachia from West Virginia to Georgia, including seven counties in North Carolina. The plant is typically found along stream banks where it’s able to take advantage of the stream-bank scouring that comes with periodic flooding and makes these areas inhospitable to many other plants. The plant’s decline can be linked to the widespread building of dams across its range, which temper the rise and fall of river floodwaters, allowing other plants species to become established; and the increasing preponderance of invasive exotic plant species, like Japanese knotweed, Japanese honeysuckle, and kudzu, that take over sites where Virginia spiraea is found.
