An Assessment Of Alternative Feed Ingredients In Practical Diets For Florida Pompano (Trachinotus Carolinus) Held In Low Salinity Recirculating Systems, Terhea Nichole Williams Dec 2008

An Assessment Of Alternative Feed Ingredients In Practical Diets For Florida Pompano (Trachinotus Carolinus) Held In Low Salinity Recirculating Systems, Terhea Nichole Williams

Electronic Theses and Dissertations

The identification of alternative protein sources for partial or whole replacement of fishmeal (FM) is a priority in the development of suitable, low cost feed formulations for the Florida pompano (Trachinotus carolinus). To evaluate alternative feed ingredients for the potential replacement of FM in diets fed to juvenile pompano, a series of four experiments were conducted. The objectives of Experiments 1 and 2 were to determine the apparent digestibility of crude protein (ADCP), energy (ADE), and apparent amino acid availability (AAAA) of three plant based ingredients (soybean meal (SBM), soy protein isolate (SPI), corn gluten meal (CGM)) and three by-product …


Effects Of Fish Introductions On The Geographic Distribution And Native Invertebrate Biodiversity Of Naturally Fishless Lakes In Maine, Emily Gaenzle Schilling Aug 2008

Effects Of Fish Introductions On The Geographic Distribution And Native Invertebrate Biodiversity Of Naturally Fishless Lakes In Maine, Emily Gaenzle Schilling

Electronic Theses and Dissertations

Widespread fish stocking has led to a worldwide decline in naturally fishless lakes and their associated communities. Little is known about the historical distribution or native communities of these freshwater ecosystems. The objectives of this study were to: 1) develop a quantitative method to remotely detect naturally fishless lakes in Maine, 2) conduct a landscape-scale assessment of unique attributes of fishless lake macroinvertebrate communities, 3) identify macroinvertebrate bioindicators of fish absence, and 4) assess effects of introduced fish on native macroinvertebrates. I identified two physiographic types of naturally fishless lakes in Maine: kettle lakes in the eastern lowlands and foothills …


A Continued Study Of The Use Of Created Ponds For Amphibian Breeding In Fragmented Forested Areas, Amy Elizabeth Schneider Jan 2008

A Continued Study Of The Use Of Created Ponds For Amphibian Breeding In Fragmented Forested Areas, Amy Elizabeth Schneider

Theses, Dissertations and Capstones

Amphibian populations are declining worldwide due to factors such as habitat degradation, fragmentation and destruction. I conducted a study to explore the use of created ponds in a forested habitat by breeding amphibians, specifically Rana sylvatica and Ambystoma maculatum. The objectives were to examine the movement of these animals after leaving the ponds, the survival and movement of juveniles, how both respond to fragmentation, and how similar the created ponds were to natural ones. Nine ponds were constructed in December 2003 in the MeadWestvaco Wildlife Ecosystem Research Forest (MWERF) in Randolph County, West Virginia. All trapped amphibians were measured and …
