Integrated Periphyton Biofilters In Marine Recirculating Aquaculture Systems, Adam N. Bell

USF Tampa Graduate Theses and Dissertations

Marine aquaculture is a growing industry that has the potential to reduce eutrophication, overfishing, and loss of biodiversity. Recirculating aquaculture systems (RAS) are a type of aquaculture system that decreases discharge, raises biological control, and conserves water; however, RAS are challenged due to high energy cost, low biodiversity, water quality control, and waste nutrients. Periphyton biofilters are a new technology that allows for feed production, water quality control, microbial diversity, and resource recovery in marine aquaculture systems. The overarching question that this dissertation investigates is, how can periphyton biofilters be integrated into RAS to address the challenges of modern sustainable …

Characterisation Of Sex Chromosome Aneuploidy In Female Cattle Using Genotype Information, Cliona Ryan

ORBioM (Open Research BioSciences Meeting)

Background

Aneuploidy is a genetic condition characterized by the loss (monosomy) or gain (trisomy) of one or more chromosomes. Aneuploidy affecting the sex chromosomes often leads to infertility. The objective of this study was to estimate the prevalence of sex chromosome aneuploidy in a large juvenile population using routinely available genotype intensity information.

Methods

Genotype and genotype intensity data was available on 145,476 female dairy and beef cattle below 15 months of age at the time of genotyping, with no recorded progeny. Genotype intensity data included the LogR Ratio (LRR), R-value (the sum of X and Y SNP probe intensities), …

Grass-Based Supplementation To Reduce Slaughter Age In Dairy-Beef Steers, Jamie O'Driscoll

ORBioM (Open Research BioSciences Meeting)

Background

Reducing slaughter age, while maintaining carcass output, will improve the sustainability of beef production systems. This will result in lower lifetime emissions from cattle, while also reducing the carbon equivalent per kilogram of beef carcass. The objective of this study was to investigate the strategic use of concentrate feed within pasture-based dairy-beef steer production systems, to establish its effectiveness in reducing slaughter age in differing animal genotypes.

Methods

Three contrasting supplementation strategies were implemented: 1) grass only (GO), pasture only diet in the first and second grazing season, 2) intermediate (INTER), concentrate supplementation throughout the first grazing season, pasture …

The Detection Of Putative Recessive Lethal Haplotypes In Irish Sheep Populations, Rory Mcauley

ORBioM (Open Research BioSciences Meeting)

In livestock populations, recessive lethal alleles are a known contributor to poor reproductive performance due to embryonic death in homozygous individuals. Despite their lethal effect in the recessive form, these alleles may be maintained at high frequencies among carrier animals because of their positive pleiotropic effects on economically important traits. Although several such recessive alleles have been identified in cattle and pig populations, limited studies have been completed in sheep, and none within Irish sheep populations. Genotype data for 69,034 animals from five major Irish sheep breeds genotyped on a variety of panels was available for this study. Only animals …

Comparison Of Dna Extraction Methods For The Detection Of Canned Tuna Species With Dna Mini-Barcoding, Aubrey J. Emmi, Biola Fatusin, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Tuna is susceptible to species mislabeling due to its high demand, quick rate of production, and wide range of price points. DNA barcoding, a sequencing-based technique, allows for the detection of species mislabeling by targeting a standardized region of DNA. A mitochondrial control region (CR) DNA barcode has been found to be capable of species discrimination for tuna, but it is challenging to recover the entire DNA fragment from canned tuna. While a short fragment of CR, referred to as a “mini-barcode,” has shown some success with canned tuna species identification, more research is needed to improve identification rates. The …
