Available in PDF, EPUB and Kindle. Book excerpt: The spawning period is of a short duration, approximately 5 days, and can begin before the ice is out of the lake. [...] At the time of the study, a beaver dam was across the mouth of a culvert under Route 785 located at the outflow of Mill Lake Stream. [...] The spawning tributaries of the large-bodied form of LURS, Mill Lake Stream and Trout Lake Stream, are located at the northeast portion of the lake. [...] Through real-time reporting of the presence of smelt, DFO initiated the mark-recapture project when the smelt appeared at the mouth of Mill Lake Stream at the beginning of spawning season. [...] However, the increase in nightly spawner abundance between the first and last day of sampling suggests that there is immigration and the system may not be closed, a violation of the assumptions of the Schnabel method, which would result in a less precise estimate.

This book was released on 2017 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Available in PDF, EPUB and Kindle. Book excerpt: Rainbow smelt (Osmerus mordax) occupy the middle of the pelagic foodweb in Lake Champlain as zooplanktivores and cannibals, while serving as the major forage fish for piscivores. The focus of this study was to (i) relate spatial and temporal distributions of young-of-the-year (YOY) and yearling-and-older (YAO) smelt to zooplanktivory patterns and (ii) to determine the effects of density and availability of larger prey (Mysis relicta and YOY smelt) on smelt individual growth rates. We used hydroacoustics to obtain smelt abundance, midwater trawling to verify acoustic targets and to collect fish for size and stomach content information, and sampled zooplankton with vertical tows throughout the lake from June to September in 2001 and 2002. From these data, diets of smelt and zooplankton consumption were related to zooplankton abundance and species composition and we calculated individual growth rates of smelt. The 2001 smelt yea class was very large, which subsequently resulted in a large number of YAO smelt in 2002. Therefore, in 2001 YOY smelt consumed a major portion of the available zooplankton whereas the majority was consumed by YAO smelt in 2002. Through bioenergetics modeling and zooplankton production estimates, we determined that zooplankton production remained positive in most months and areas during both years despite high consumption of zooplankton by smelt. Seasonally, smelt consumed more zooplankton in September than in June or July. Through AIC analyses, we concluded that YOY growth rates were negatively influenced by YOY density and YAO growth rates were positively influenced by the abundance of Mysis in diets. The findings of this study provide a substantial contribution to our knowledge of the Lake Champlain food web, especially in light of the recent invasion of alewife (Alosa pseudoharengus). Preinvasion levels of smelt consumption and growth rates will be the information needed to document the effect of alewife on the food web as the alewife population becomes more abundant.
