Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg 2017 University of Southern Mississippi

Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg

Master's Theses

Invasive Red Lionfish (Pterois volitans) were first detected in the northern Gulf of Mexico (nGOM) in 2010 and since then their numbers have increased dramatically. From 2010 to 2015, more than 15,000 Red Lionfish were collected opportunistically from the nGOM for this study. Length and weight relationships differed significantly among ecoregions by sex and there was clear sexual dimorphism in size with males being larger and heavier. Red Lionfish age ranged from 0-4.5 years old and males achieved greater growth rate (K) and asymptotic maximum lengths (Linf) compared to females and these parameters were also different by ...


From Disaster To Sustainability: The Story Of The Pacific Groundfish, Matthew Richards 2017 Utah State University

From Disaster To Sustainability: The Story Of The Pacific Groundfish, Matthew Richards

All Graduate Plan B and other Reports

This paper reviews the circumstances that led to the collapse of the Pacific groundfish fishery and the steps that fishery managers took to curb over-harvesting and bring the fishery back to sustainability. Fishery managers utilized various management tools such as a vessel buyback program, regulatory mechanisms, and market strategies to improve the available data on the fishery, improve safety for fishermen, and reduce harvest rates and overcapitalization. By employing a diverse range of measures, managers developed a system by with they successfully balanced conservation objectives and minimized adverse impacts to fishing communities. Overcapitalization and overharvest continue to degrade the health ...

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 2016-2017, Brian K. Gallagher, Mary C. Fabrizio, Troy D. Tuckey 2017 Virginia Institute of Marine Science

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 2016-2017, Brian K. Gallagher, Mary C. Fabrizio, Troy D. Tuckey

Reports

The 2016 Striped Bass juvenile abundance index was 5.15 and was not significantly different from the reference mean of 7.77 observed in 1980-2009. Abundance indices in the James, York and Rappahannock rivers in 2016 were not significantly different than their historic averages (1967-2015). Juvenile White Perch abundance indices in 2016 were near historic averages in the York and Rappahannock rivers, but below the historic average in the James River. Because a new seine net was used during the 2016 survey, catches of Striped Bass and White Perch were adjusted using preliminary calibration factors derived from paired hauls of ...

Determination Of Metal Concentrations In Sediments Of Big Walnut Creek, Hayley Quinn, Joan M. Esson, Kierra M. Lathrop, Michael A. Hoggarth, Kevin Svitana, Nathan Hess

Distinction Papers

The freshwater mussel populations in the lower stretch of Big Walnut Creek in central Ohio have been found to vary along the run of the creek with the lowest population of mussels in the middle stretch. One possible cause for the decline is the presence of contaminants in the sediments of the creek. In this study, nine Sites along the creek were examined. At each Site, sediment samples from a pool region and two quadrants from where mussels were also studied (the area of interest) were collected, along with pseudo feces, which is the waste mussels produce as they filter ...

A Reexamination The Freshwater Mussels (Family Unionidae) In Lower Big Walnut Creek, Kierra M. Lathrop 2017 Otterbein University, Ohio

A Reexamination The Freshwater Mussels (Family Unionidae) In Lower Big Walnut Creek, Kierra M. Lathrop

Distinction Papers

Freshwater mussels (family Unionidae) have become increasingly rare as the threats to water quality, habitat quality, and other aquatic animals, which the mussels depend on, have increased. The absence of mussels can provide evidence that one of these factors is insufficient. Lower Big Walnut Creek (BWC) is known to support a diverse community of mussels but they are unevenly distributed throughout the creek with abundance, density, and richness being high in the upper section, very low in the midsection, and intermediate in the lower section. It has been suggested water quality nor symbiotic fish host communities are responsible for this ...

The Effect Of Water Levels On Crayfish Aggression, Emory B. Johnson, Sarah E. Blase

Seaver College Research And Scholarly Achievement Symposium

Crayfish are a very prevalent invasive species that affect many different environments all over the world. Crayfish, specifically Procambarus clarkii, are an invasive species that have currently taken a foothold in the Santa Monica mountains and are threatening native stream species. There is currently a severe drought occurring in the Santa Monica mountains. The drought has been reshaping many aquatic environments by limiting space and resources such as food and shelter. Crayfish are a very aggressive species and adversely affect the habitat they inhabit by rapidly colonizing, burrowing, and their voracious diets. Due to the adverse effects crayfish can have ...

Urban Recreational Fisheries In The Australian Coastal Zone: The Sustainability Challenge, Daryl McPhee 2017 Bond University

Urban Recreational Fisheries In The Australian Coastal Zone: The Sustainability Challenge, Daryl Mcphee

Faculty of Society and Design Publications

Recreational fishing is an important wildlife harvesting activity in urban coastal areas, and recreational harvest in these areas can frequently exceed the commercial harvest. Recreational fishing is a key way that many members of the public experience the environment. The activity enhances social capital, promotes respect for nature, provides health benefits and can provide economic benefits to coastal communities. It is also an important driver of the science on aquatic animals and habitats, and an important tangible reason for many members of the public to conserve and protect aquatic resources. Overall, there has been little specific consideration of urban recreational ...


Transcriptome Approach For Identifying Potential Biomarkers For Endocrine Disruption Due To Crude Oil Exposure Using Killifish (Fundulus Heteroclitus)., Frank J. Zadlock IV 2017 Seton Hall University

Transcriptome Approach For Identifying Potential Biomarkers For Endocrine Disruption Due To Crude Oil Exposure Using Killifish (Fundulus Heteroclitus)., Frank J. Zadlock Iv

Seton Hall University Dissertations and Theses (ETDs)

The killifish, Fundulus heteroclitus, is a common fish model in aquatic toxicology. However, little is known in this organism about how endocrine disrupting compounds, (EDCs) including polycyclic aromatic hydrocarbons (PAHs), impact the reproductive status from a molecular standpoint. The objective of this project is to apply high throughput sequencing to F. heteroclitus testes to examine the molecular mechanisms that impair reproduction when exposed to crude oil. First, a crude oil exposure experiment was conducted. Following exposure, semi-quantitative PCR was performed to detect changes in gene expression of the following genes known to respond to EDCs: gonadal aromatase (CYP19a), vitellogenin (VTG ...

An Overview Of Aquaponic Systems: Hydroponic Components, D. Allen Pattillo 2017 Iowa State University

An Overview Of Aquaponic Systems: Hydroponic Components, D. Allen Pattillo

NCRAC Technical Bulletins

Aquaponics is the union of hydroponics (growing plants without soil) and aquaculture (farming fish or other aquatic organisms) for a fast, efficient method of producing both plant and fish crops. Fish waste from the aquaculture portion of the system, is broken down by bacteria into dissolved nutrients (e.g., nitrogen and phosphorus compounds) that plants utilize to grow in a hydroponic unit. This nutrient removal not only improves water quality for the fish but also decreases overall water consumption by limiting the amount released as effluent.


Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2016, Mary C. Fabrizio, Troy D. Tuckey 2017 Virginia Institute of Marine Science

Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2016, Mary C. Fabrizio, Troy D. Tuckey

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193 ...

Tracking Decadal Changes In Striped Bass Recruitment: A Calibration Study Of Seine Surveys In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Olivia M. Philips, Brian K. Gallagher

Reports

In this study we estimated calibration factors necessary to maintain the long‐term integrity of the juvenile striped bass surveys in the Chesapeake Bay region. These surveys provide annual indices of recruitment (estimated as juvenile fish abundance in summer) and are used by fisheries managers in Virginia and Maryland to inform adjustments of annual harvest limits for striped bass from the commercial and recreational fisheries in Chesapeake Bay. During the multi‐decadal history of the survey, a potentially influential change occurred: VIMS deployed a net (the VA net) with a mesh material that differed from the standard net that MD ...
