Report on the progress of management plan implementation for the yellow lampmussel (Lampsilis cariosa) in Canada for the period 2010-2015 . : En3-5/6-1-2017E-PDF

"The main threats to both populations of Yellow Lampmussel include changes to habitat and water quality and the potential introduction of non-native and invasive aquatic species. Specific threats to the Sydney River Yellow Lampmussel population include sedimentation resulting from shoreline activities and the use of garden or agricultural chemicals; the presence of invasive aquatic predators such as Chain Pickerel (Esox niger) and Smallmouth Bass (Micropterus dolomieu) that threaten their host fish species; the potential use of molluscicides (pesticides targeting molluscs, used to control snail and slug pests); the potential introduction of Zebra Mussels (Dreissena polymorpha); and predation by Muskrats (Ondatra zibethicus). Specific threats to the Saint John River Yellow Lampmussel population include riparian development and sedimentation resulting from poor forestry and agricultural practices; eutrophication and pollution due to run-off of agricultural chemicals and other inputs; the potential introduction of Zebra Mussels and the presence of the invasive aquatic predatory fish that may impact their host fish populations. The goal of the Management Plan is to maintain the existing Yellow Lampmussel populations in Canada. The five objectives of the Plan are to: maintain current quality and quantity of known Yellow Lampmussel habitat; reduce direct threats to Yellow Lampmussel populations; improve our understanding of Yellow Lampmussel populations in New Brunswick and Nova Scotia; maintain existing host fish populations; and increase public awareness and involvement in Yellow Lampmussel conservation efforts"--Executive summary, p. iii.
