The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser
The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser
Electronic Theses and Dissertations
Arsenic is a toxic metalloid that exceeds safe drinking water standards in groundwater in many locations worldwide. Arsenic exposure in fish has been linked to destruction of gill tissues, impairment of growth, decreased muscle mass, memory impairment, increased aggression, and avoidance behaviors. We examined the behavior of mummichogs (Fundulus heteroclitus) following arsenic exposure during development in two studies. Embryos were collected from fish from three reference sites: Scorton Creek (SC), Massachusetts, Wells Harbor (WE), Maine, and Block Island (BLOC), Rhode Island and two contaminated sites: Callahan Mine (CM), Brooksville, Maine, and New Bedford Harbor (NBH), Massachusetts. Embryos were …
Hydroacoustic Analysis Of The Effects Of A Tidal Power Turbine On Fishes, Haley Viehman
Hydroacoustic Analysis Of The Effects Of A Tidal Power Turbine On Fishes, Haley Viehman
Electronic Theses and Dissertations
Tidal currents help shape coastal marine environments and are essential in life cycles of many fish species. Areas with strong tidal currents are also targeted by humans for energy extraction via tidal energy turbines. The effects of these devices on fishes are difficult to predict because fish behavior within fast tidal currents is largely unstudied. Based at a tidal energy site in Cobscook Bay, Maine, this work sought to describe fish reactions to a tidal energy device, to understand the natural presence of fish at the site, and to provide guidance for future monitoring of tidal energy device effects in …

The Fresh-Water Fishes Of Maine, Flavia Lucile Richardson
Electronic Theses and Dissertations
The purpose of this investigation is to determine the present status of the fish fauna of Maine. Data assembled during the course of this study includes descriptions of native and introduced species, records concerning their present distribution, and the extent of the official introduction of non-indigenous species. From this material may be derived conclusions respecting the survival of the introduced species and the probable capacity of the native species to successfully compete with them. Through the use of descriptive material assembled during the investigation of species it has been possible to construct a key as an aid in identifying any …
