Mussels & Duck RiverCurrent Lecture Fisheries Conservation- Pigeon Rivero They had to come up with a species list of native fish in order to reintroduce them. They did this by viewing historic stream records before the mill, field guides (Range Maps), and similar, adjacent river fauna. o Then, the collection of fish from other rivers was conducted to reintroduce the fish to the Pigeon River. These methods are listed below. Kick seining: It required several people. No gaps could exist under the net. People would stir up sediment and kick rocks to guide the fish into the net. Canary in the coal mine: Saffron shiners, mirror shiners, silver shiners, and telescope shiners were collected. The telescope shiners are not tolerant to sedimentation; therefore, they are a test for nonpoint source pollution. Backpack shocking: Fish are temporarily stunned by the electrical current.o The fish must be tagged to be able to define the reintroduced fish. They were tagged using various colors of Visible Implant Fluorescent Elastomer (VIE). Silicone-based liquid was injected into the fish. This liquid would cure into a pliable solid. The color was implanted beneath transparent tissue. o While handling these fish, precautions were taken to minimize stress on the fish. The temperature of the water needed to be similar to the temperature of the river of origin. The water must also be well oxygenated. Hands were used as littleas possible or none at all.

Salinity and pH are important factors to consider. o These fish were monitored by snorkeling and seining surveys. The annual Index of Biotic Integrity (IBI) can be used. The introduced fish are located by their tag. Also, untagged fish are indicative of good reproduction. o The survival of the relocated fish and reproduction in Tennessee led to the expansion into North Carolina in 2004.o 21 species of fish, 2 genera of snails in 11 miles, and 6 species of mussels have been reintroduced into the Pigeon River.- Mussels and Duck Rivero Mussels are filter feeders and clean the water. They do this by their siphon. Theycan filter up to 50 gallons per day.o Fish are the hosts for mussels in the beginning stages of life. A mussel will imitate a fish by their foot to attract other fish. When this fish attacks the mussel’s foot, the mussel releases her young into the fish’s mouth. These young mussels will attach to the fish’s gills and feed off of their blood. o Mussels were originally eaten by Native Americans. They were even used as buttons by Americans until plastic was invented.o Mussels can be aged by the rings on their shell.o They can be harvested by diving and brailing.o Mussels serve as food for otters, raccoons, muskrats, waterfowl, and fish.o A mussel silo hold mussels in a container so they can clean the water.o Mussels can grow to be 10-12 pounds, but it depends on the species. Growth also is affected by water temperatures, which should be cold but warmer, and nutrients.o Duck River contains 55 species of mussels, but 3 species are endangered. This number is significant compared to other rivers. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a
