The welfare and quality of farmed salmonids at harvest.
… on the stress response and carcass quality of farmed salmonids with a view to recommending best practice. Current salmonid harvesting techniques were determined via a questionnaire circulated to the industry. Commonly used killing/ stunning methods were tested for their effects on the welfare …

Animals without Borders: Farmed Animal Resistance in New York
While billions of farmed animals are immobilized within agribusiness, every year some of these animals manage to break free. This thesis examines the stories of those who flee slaughterhouses and the public response to these individuals. My objective is to understand how animals resist and the role …

Epidemiology of Mycoplasma bovis in farmed bison in western Canada
… bovis is emerging as an important pathogen of farmed bison in North America, associated with high morbidity and mortality. The present work aimed to investigate the epidemiology of M. bovis-associated disease in western Canadian farmed bison. A telephone survey determined that 6% of 202 bison …

Variance Components of litter size in Icelandic farmed mink (Neovison vison)
An analysis of variance components and a study of pedigree structure was carried out using Icelandic field data. Data from six farms was included, total of 88°928 animals in the pedigree. Two methods were employed, MCMC Gibbs sampler method and REML. The two different methods gave similar results. …

The Use of Fishery Wastes in the Feeds for Farmed Fish
… of using fishery wastes in commercial feeds for farmed fish was investigated; the first of these is their use in semi-moist feeds. It was found that neither the inclusion of fishery products nor the moisture content of the diet had a significant effect upon the growth rate or dry matter …

Wild Turkey Ecology in Two Intensively Farmed Landscapes in Central Illinois
Hens moved long distances between seasonal activity centers and annual range size averaged 712.4 ha. Fall/winter ranges averaged 701.4 ha (SE = 102.3, n = 71) and were larger and more variable than nesting season ranges which averaged 404.0 ha (SE = 36.7, n = 93). Upland forest was preferred during …

Optimising the growth of Cryptococcus species SS1, a potential probiotic for farmed abalone
Farmed abalone is a reliable and good quality source of abalone. Cryptococcus species SS1 was isolated from the gut of the South African abalone, Haliotis midae, and has been identified as a potential probiotic for farmed abalone. The implementation of strain SS1 as a probiotic for aquacultured …

Pseudoalteromonas sp. strain C4 as a probiotic for farmed South African abalone, Haliotis midae
… the growth and decreased the susceptibility of farmed abalone to pathogenic bacterial infection. The mechanism by which the probiotic is able to increase growth rates and reduced susceptibility to pathogen infection was investigated. A number of bacterial strains were isolated from the digestive …

Developing Production Techniques and A Site Assessment Tool for Forest Farmed Ramps in Appalachia
The Allium tricoccum Aiton (ramps, aka wild leeks), a native spring ephemeral, is a cultural keystone species in Appalachia, a mountainous physiographic region encompassing 205,000 square miles of the eastern United States. People in Appalachia have long harvested ramps in the wild. However, …

Experimental field studies and predictive modelling of PCB and PCDD/F levels in Australian farmed Southern Bluefin Tuna (Thunnus maccoyii).
Farmed Southern Bluefin Tuna (SBT) (Thunnus maccoyii) is an important export product for South Australia (SA). It is exported to Japan, China, Korea and the United States for the sushi and sashimi markets. The primary purpose of SBT farming in SA is to fatten wild-caught juvenile fish (2-4 years of …

Characterization of the molecular genetic variation in wild and farmed Nile tilapia Oreochromis niloticus in Ghana for conservation and aquaculture development
… climate change, and hybridization with farmed populations. Knowledge of the genetic variation among wild populations also can contribute to foundation and selection of genetically diverse populations for aquaculture. I assessed the genetic variation among tilapia populations using …

Chemical, Physical and Sensorial Compositions of Farmed and Wild Yellow Perch (Perca flavescens), Southern Flounder (Paralichthys lethostigma) and Coho Salmon (Oncorhynchus kisutch)
… physical and sensorial properties of wild and farmed fish. Farmed yellow perch fillets showed higher lipid contents (2.78% vs. 1.39%); softer texture (0.41 J/g vs. 0.53 J/g); whiter color (higher L* and lower b* values); different fatty acid profile (higher n-3/n-6 ratio), and mineral …

Probiotic effect of Vibrio midae SY9, Cryptococcus sp. SS1 and Debaryomyces hansenii AY1 on the growth and disease resistance of farmed Haliotis midae
… the growth rate and disease resistance of farmed H. midae. Erasmus et al. (1997) showed that abalone enteric bacteria enhanced digestive efficiency by secreting polysaccharolytic enzymes and it was suggested from these results that these bacterial enzymes could affect the growth rate of …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
Unlike most prairie nesting ducks (Anas spp.), the North American population of northern pintails (A. acuta, hereafter pintails) has failed to respond as expected to improved wetland conditions on the U.S. and Canadian prairies during the mid to late 1990s. My primary objectives were to test the …

A Physiological Assessment of Wetland Habitats for Spring-migrating Ducks in the Agricultural Landscapes of the Southern Prairie Pothole Region
… the contributions of wetlands in intensively-farmed landscapes for spring-migrating ducks. I measured a number of biotic attributes of wetlands including the density of aquatic invertebrates and submersed macrophytes and abundance of spring-migrating ducks. I also measured concentrations of …

Ulva as a functional feed: a practical investigation into the effects of Ulva lacinulata on the growth, consumption, health and gut microbiota of the farmed abalone Haliotis midae
Since around 2000, there has been increased adoption of cultivation of the macroalga Ulva by the South African abalone aquaculture industry using IMTA systems. Farms that use fresh Ulva as a supplement to formulated feed have reported a reduction in the volume of formulated feed required to achieve …
