This book was released on 2016 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 2006, the Deepwater Sculpin (Great Lakes-Western St. Lawrence populations) was designated a species of Special Concern in Canada by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), and was listed on Schedule 1 of the Species at Risk Act (SARA) in 2007. The COSEWIC designation was based on the species' restricted distribution and the loss of two populations in addition to the possibility of a decline in one further population. Although the Deepwater Sculpin is also widely distributed in western Canada (Western populations), these populations were assessed as Not at Risk and, hence, are not included in this management plan. The long-term (> 20 years) goal of this management plan is to ensure the long-term persistence of Deepwater Sculpin throughout its current and historical distribution in the Great Lakes - Western St. Lawrence DU. Management should be directed towards ensuring the conservation and restoration of habitat for known populations. More quantifiable objectives relating to individual populations will be developed once the necessary sampling and analysis have been completed"--Executive summary, p. iv.

This book was released on 2019 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Great Lakes, slimy sculpins (Cottus cognatus) and deepwater sculpins (Myoxocephalus thompsonii) were historically abundant native deepwater fishes that served as important prey items for native piscivores (e.g., lake trout, Salvelinus namaycush, and burbot, Lota lota). However, both of these species have been declining in abundance and biomass recent decades according to USGS trawl surveys. The timing of these declines in sculpin biomass and abundance coincides with several ecological disturbances that have occurred throughout the Great Lakes, including the invasions of dreissenid mussels (zebra, Dreissena polymorpha; quagga, D. bugensis) and the aggressive round goby (Neogobius melanostomus), along with the collapse of Diporeia (formerly one of the most important prey items for these sculpin species). In this dissertation, we provide a comprehensive review of the state of knowledge and investigate the effect of these ecological disturbances on slimy and deepwater sculpins in the Great Lakes. We predicted that these ecological disturbances have negatively affected both slimy and deepwater sculpin populations, particularly slimy sculpins, which we could observe through changes in their spatial (depth) distribution patterns (e.g., shifting deeper to avoid round goby) and body condition (e.g., lower body condition associated with ecological disturbance). Our results indicate that slimy sculpins may be more vulnerable to these ecological disturbances than deepwater sculpins, but data limitations prevent us from offering conclusive causal mechanisms for sculpin spatial and body condition patterns. Both our review and analyses implicate that we need to gain a better understanding of sculpins in order to restore these species in this system.
