Movement And Habitat Use Of Selected Nongame Fishes In A Minnesota Lake, Michael David Habrat Dec 2007

Movement And Habitat Use Of Selected Nongame Fishes In A Minnesota Lake, Michael David Habrat

Theses and Dissertations

Aquatic vegetation provides important habitats for fish, but these habitats are increasingly being altered anthropogenically. My research evaluated the movement and habitat use of three small rare fish species, the blackchin shiner Notropis heterodon (BCS), blacknose shiner Notropis heterolepis (BNS), and banded killifish Fundulus diaphanous, in a Minnesota lake. BCS and BNS traveled farther in spring than summer, but selection of habitat based upon macrophyte biovolume did not explain these differences. All three fish species traveled long distances (> 1,800 m) and were capable of reaching all available habitats in Square Lake. Macrophyte species richness and prey (zooplankton) abundance were …

Relationships Between Volatile Flavor Compounds, Sensory Descriptors And Consumer Acceptability Of American Dry-Cured Ham, Alessandra Julian Pham-Mondala Dec 2007

Relationships Between Volatile Flavor Compounds, Sensory Descriptors And Consumer Acceptability Of American Dry-Cured Ham, Alessandra Julian Pham-Mondala

Theses and Dissertations

The relationships between volatile flavor compounds, sensory descriptors and consumer acceptability were determined for eight commercial American dry-cured hams using external preference and flavor mapping. The majority of consumers preferred (p<0.05) hams that had more intense caramelized, smoky, savory and molasses aromas as well as more intense sweet and savory flavors. Sixteen aroma impact compounds were identified from the headspace volatiles of dry-cured hams. The consumers with the highest acceptability scores preferred (p<0.05) hams that were characterized by 4-methyl-2-methoxyphenol (sweet ham), 4-ethyl-2-methoxyphenol (sweet ham), 2-methoxyphenol (smoky, cocoa), 2,6-dimethoxyphenol (smoky ham, savory) and 2uranmethanol (burnt meat, vitamin). Fourteen percent of consumers preferred (p<0.05) two hams that were characterized by methional (baked potato). Consumer acceptability scores were lower for hams either characterized by methanethiol (sulfur), carbon disulfide (sulfur), 2-butanone (sweet), 3-methylbutanal (malty, fermented), 2-heptanone (burnt meat, vitamin), hexanal (cut grass), benzeneacetaldehyde (floral), 1-octen-3-ol (mushroom) or characterized by benzaldehyde (burnt meat, cooked meat) and limonene (citrus).
