Resource Assessment Report Temperate Demersal Elasmobranch Resource Of Western Australia, Matias Braccini, Nick Blay, S. A. Hesp, Brett Molony
Resource Assessment Report Temperate Demersal Elasmobranch Resource Of Western Australia, Matias Braccini, Nick Blay, S. A. Hesp, Brett Molony
Fisheries research reports
This document provides a cumulative description and assessment of the TDER and all of the fishing activities (i.e. fisheries / fishing sectors) affecting this resource in WA. Future Resource Assessment Reports will assess the Statewide Sharks and Rays Resource. The report is focused on the temperate indicator species (whiskery, gummy, dusky and sandbar sharks) used to assess the suites of demersal sharks and rays that comprise this resource. These species are primarily captured by demersal gillnets used in the TDGDLF that operate in the West Coast and South Coast Bioregions. For the North Coast bioregion, no commercial fishing for sharks …

Development And Application Of Aquatic Toxicology Studies For The Assessment Of Impacts Due To Chemical Stressors Using Non-Standard Indigenous Organisms, Abraham Jeffrey Smith
Development And Application Of Aquatic Toxicology Studies For The Assessment Of Impacts Due To Chemical Stressors Using Non-Standard Indigenous Organisms, Abraham Jeffrey Smith
FIU Electronic Theses and Dissertations
Research in the multidisciplinary science of ecotoxicology is crucial to assess injuries to ecosystem resources from chemical spills or other stressors used to support environmental decision-making. Established guidelines recommend the use of non-standard native species in toxicity investigations. This work focused on the use of native species for aquatic toxicity assessment to make more relevant conclusions on the potential for adverse biological effects to occur as a result to single chemical exposures or exposures to a complex mixture like oil. We apply these studies to investigate petroleum product impacts from the Deepwater Horizon incident and concerns for metal toxicity in …
Barriers To The Elimination Of Plastic In Single Use Beverage Containers In Byron Bay, Nsw, Katherine Senechal
Barriers To The Elimination Of Plastic In Single Use Beverage Containers In Byron Bay, Nsw, Katherine Senechal
Independent Study Project (ISP) Collection
Plastic debris is a global threat to the natural environment. The accumulation of plastic debris has resulted in the destruction of marine habitat as well as a threat to marine wildlife. Single use plastics, including plastics associated with single use food and beverage containers are contributing to a considerable amount of debris and other litter in the world’s oceans. As awareness of this issue spreads, both large corporations and small businesses are beginning to transition to plastic alternatives for their single use beverage containers. In Byron Bay, Australia, an area of increasing environmental awareness, businesses are beginning to reduce single …
Takataka Talk: Waste Presence And Management In Ushongo, Kristen Jones
Takataka Talk: Waste Presence And Management In Ushongo, Kristen Jones
Independent Study Project (ISP) Collection
Increasingly high levels of waste are being generated each year, resulting in millions of tonnes of plastic and other debris ending up in marine and coastal environments. The impacts of the debris on these environments are wide ranging, affecting both environmental health and human wellbeing. Still though, there is a lack of information concerning the presence and effect of garbage in many coastal and marine ecosystems around the globe. This project studied the presence and management of coastal waste along a small portion of the coast of Tanzania, near the village of Ushongo. General distribution, level, and type of garbage …

Aerial applications of liquid methoprene are used in salt marshes to control mosquitoes by preventing adult emergence. Despite concern about toxicity to non-target organisms, little is known about environmental concentrations after applications, nor methoprene's persistence in salt marsh environments. Aqueous and sediment samples were collected from two marshes receiving weekly applications. Aqueous samples were collected as early as 30 minutes after applications and as long as nine days afterwards; sediment samples were taken within hours of application and as long as 19 days post-application. Use of time-of-flight liquid chromatography – mass spectral analysis allowed for ultra low detection limits (0.5 …

Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle
Theses, Dissertations and Capstones
Traditional direct water quality methodologies limit the ability to spatially and temporally predict algal blooms in lotic systems due to the size and characteristics of large river systems. Algal blooms potentially can be predicted by knowing the spatial and temporal patterns of change in cyanobacteria concentrations at large scales. Remote sensing studies investigating freshwater algal blooms, some known to secrete harmful toxins, are primarily conducted on lentic systems while large lotic systems are greatly ignored. In this study I developed a chlorophyll concentration estimation model for the Ohio River using a satellite remote sensing approach. Ground-truth water quality measures, including …
