Abstract
Pothoven SA, Hondorp DW, Nalepa TF. Declines in deepwater sculpin Myoxocephalus thompsonii energy density associated with the disappearance of Diporeia spp. in lakes Huron and Michigan.
Ecology of Freshwater Fish 2011: 20: 14–22. Published 2010. This article is a US Government work and is in the public domain in the USA. Abstract – The deepwater sculpin Myoxocephalus thompsonii is a glacial relict in the Laurentian Great Lakes that primarily consumes two glacial relict crustaceans, Mysis relicta and Diporeia spp. Deepwater sculpin were collected in Lake Michigan off Little Sable Point (in 2001) and Muskegon, Michigan (in 2001 and 2009), and in Lake Huron off Harbor Beach, Michigan (in 2007) for energy density and diet analyses. These sites and years represented differences in available prey. In Lake Michigan, energy densities of deepwater sculpin in 2001 were similar to those reported in 1969–1971. In contrast, energy content declined at least 26% at Muskegon between 2001 and 2009. Overall, energy density was 31–34% higher at a site with abundant Diporeia spp. compared with two sites without Diporeia spp. Deepwater sculpin diets consisted primarily of M. relicta at all sites, but included 10–17% (dry mass) Diporeia spp. at sites where this crustacean was still abundant. Food biomass in stomachs was higher at sites with abundant Diporeia spp. than at those without Diporeia spp. Deepwater sculpin energy density and food biomass in stomachs were similar between two sites without Diporeia spp. despite differences in abundance of remaining prey, M. relicta. Declines in deepwater sculpin energy density suggest the potential for further effects on other species and changes in the flow of energy through the food web of the Great Lakes.

In contrast, energy content declined at least 26% at Muskegon between 2001 and 2009. Overall, energy density was 31–34% higher at a site with abundant Diporeia spp. compared with two sites without Diporeia spp. Deepwater sculpin diets consisted primarily of M. relicta at all sites, but included 10–17% (dry mass) Diporeia spp. at sites where this crustacean was still abundant. Food biomass in stomachs was higher at sites with abundant Diporeia spp. than at those without Diporeia spp. Deepwater sculpin energy density and food biomass in stomachs were similar between two sites without Diporeia spp. despite differences in abundance of remaining prey, M. relicta. Declines in deepwater sculpin energy density suggest the potential for further effects on other species and changes in the flow of energy through the food web of the Great Lakes.</abstract><subject lang="en"><genre>Keywords</genre><topic>glacial relict</topic><topic>deepwater sculpin</topic><topic>Diporeia</topic><topic>Mysis</topic><topic>Great Lakes</topic></subject><relatedItem type="host"><titleInfo><title>Ecology of Freshwater Fish</title></titleInfo><identifier type="ISSN">0906-6691</identifier><identifier type="eISSN">1600-0633</identifier><identifier type="DOI">10.1111/(ISSN)1600-0633</identifier><identifier type="PublisherID">EFF</identifier><part><date>2011</date><detail type="volume"><caption>vol.</caption><number>20</number></detail><detail type="issue"><caption>no.</caption><number>1</number></detail><extent unit="pages"><start>14</start><end>22</end><total>9</total></extent></part></relatedItem><identifier type="istex">61E9C2A82117D0BA1719935544FBC0FA2C2BF71E</identifier><identifier type="DOI">10.1111/j.1600-0633.2010.00447.x</identifier><identifier type="ArticleID">EFF447</identifier><accessCondition type="use and reproduction" contentType="copyright">Published 2010.
