Protocols for monitoring spawning populations of Lake Utopia rainbow smelt (Osmerus mordax) [electronic resource] / by D. MacDonald and C. Burbidge. Dartmouth, N.S. : Fisheries and Oceans Canada, Maritimes Region, 2017. iv, 51 p. : ill. (mostly col.), col. map Canadian technical report of fisheries and aquatic sciences, 1488-5379 ; 3195 Includes biliographical references (p. 28-29). "Two populations of Rainbow Smelt (LURS) co-exist in Lake Utopia: a small-bodied form (SbP) listed as threatened under the Species at Risk Act (SARA), and a large-bodied form (LbP) under consideration for listing under SARA. The two populations differ in physical characteristics, life-history, and are reproductively isolated. This report outlines methods (and provides corresponding data collection forms) for monitoring the occupation and spawning by LURS in their Lake Utopia spawning streams and includes four activities: 1) Annual monitoring for the occupation (presence or absence) of LURS in specified spawning streams; 2) Annual monitoring for the presence of obstructions and barriers in specified LURS spawning streams; 3) Monitoring water depth in Mill Lake Stream; and 4) Nighttime monitoring in Mill Lake Stream in support of LURS-LbP abundance surveys. Following these protocols should promote a consistent approach to measuring progress towards survival and recovery of LURS as outlined in their Recovery Strategy and Action Plan"--Abstract, p. iv.
