Capstone Abstract

December 27, 2016

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …


Stress Physiology And Weapon Integrity Of Intertidal Mantis Shrimp Under Future Ocean Conditions, Maya Devries, Summer Webb, Jenny Tu, Esther Cory, Victoria Morgan, Robert Sah, Dimitri Deheyn, Jennifer Taylor Dec 2016

Stress Physiology And Weapon Integrity Of Intertidal Mantis Shrimp Under Future Ocean Conditions, Maya Devries, Summer Webb, Jenny Tu, Esther Cory, Victoria Morgan, Robert Sah, Dimitri Deheyn, Jennifer Taylor

Faculty Publications, Biological Sciences

Calcified marine organisms typically experience increased oxidative stress and changes in mineralization in response to ocean acidification and warming conditions. These effects could hinder the potency of animal weapons, such as the mantis shrimp’s raptorial appendage. The mechanical properties of this calcified weapon enable extremely powerful punches to be delivered to prey and aggressors. We examined oxidative stress and exoskeleton structure, mineral content, and mechanical properties of the raptorial appendage and the carapace under long-term ocean acidification and warming conditions. The predatory appendage had significantly higher % Mg under ocean acidification conditions, while oxidative stress levels as well as the …

Journal of Marine Science and Technology

Coastal zones located in populated and rapidly developing areas face high risks of natural and anthropogenic disasters. In this study, a framework was developed to determine the indicators of vulnerability to natural and anthropogenic disasters in Chuwei and Tamsui, two northern Taiwanese fishing villages in the coastal zone of the Tamsui River. The analytical hierarchy process (AHP) was used to determine the vulnerability indices of the locations, with experts evaluating the weights assigned to a range of criteria, namely hydrological data (such as sea surface temperature and sea level), stakeholder perceptions, and fishery data. These two villages have a considerably …


Predicting The Catch Potential Of Skipjack Tuna In The Western And Central Pacific Ocean Under Different Climate Change Scenarios, Kuo-Wei Yen, Nan-Jay Su, Tooreka Teemari, Min-An Lee, Hsueh-Jung Lu Dec 2016

Predicting The Catch Potential Of Skipjack Tuna In The Western And Central Pacific Ocean Under Different Climate Change Scenarios, Kuo-Wei Yen, Nan-Jay Su, Tooreka Teemari, Min-An Lee, Hsueh-Jung Lu

Journal of Marine Science and Technology

Skipjack tuna (Katsuwonus pelamis) constitute an important migratory species that contributes significantly to the economy and the global fishery industry. Skipjack tuna play a vital role in the marine ecosystem, particularly in tropical waters of the western and central Pacific Ocean (WCPO). However, climate change may affect the characteristics of fishery resources, leading to substantial reallocation and reduction of the biomass of this species in the WCPO. In this study, catch and effort data for skipjack tuna were collected from a purse seine fishery and subsequently analyzed in combination with remote-sensing environmental variables and simulation data from climate models under …

Journal of Marine Science and Technology

In this study, information on landform change in Baramarae tidal flat, Korea is analyzed using multi-temporal Landsat images and grain size measurement data. Unlike previous studies that focused on the extraction of topographic changes from intertidal digital elevation models (DEMs), information on landform change is assessed in the present study by considering both topography and surface sediment characteristics. DEMs in 2000 and 2010 were first generated using waterlines extracted from 16 Landsat images. Mean grain size distribution maps were also generated by interpolating sample data acquired in the field in 2002 and 2012. The non-spatial and spatial characteristics of the …


Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang Dec 2016

Impact Of Climate Change On Shihmen Reservoir Water Supply, Tai-Yi Chu, Jyun-Long Lee, Wen-Cheng Huang

Journal of Marine Science and Technology

This study evaluated the impact of climate change on the water supply of the Shihmen reservoir in northern Taiwan. Five downscaled general circulation models that represent the daily meteorological data of 2046-2065 were adopted. The future inflow of the Shihmen reservoir was estimated using the tank model. Subsequently, the water supply risk under the given demand and operating conditions was simulated and assessed. Compared with 2004-2011, the average annual precipitation of the Shihmen watershed in 2046-2065 is lower, particularly during the wet season (May-October). Therefore, the risk to the water supply will increase in the first cropping season (from March …


Risk Maps And Coastal Defense Criteria In Taiwan, Wei-Po Huang, Lien-Kwei Chien, Lee-Hsueh Lee Dec 2016

Risk Maps And Coastal Defense Criteria In Taiwan, Wei-Po Huang, Lien-Kwei Chien, Lee-Hsueh Lee

Journal of Marine Science and Technology

To promote sustainable development, the Coastal Zone Management Act prescribes that coastal areas should be divided into two levels of protection zones. However, the complexity and variety of coastal defenses and land use cannot be described completely by using these two levels alone. Coastal risk maps, based on natural and manmade characters of a region, showing different degrees of vulnerability and hazard potentials, can aid in making decisions. In this study, the criteria for coastal protection and land use in terms of risk maps were adopted. A tentative risk map was presented for the northern Kaohsiung City coastal area, Southwest …


Understanding The Importance Of Intermittently Fragmented Stream Habitat For Isolated Westslope Cutthroat Trout (Oncorhynchus Clarki Lewisi) In The Colville National Forest, Washington, Forrest Michael Carpenter Dec 2016

Understanding The Importance Of Intermittently Fragmented Stream Habitat For Isolated Westslope Cutthroat Trout (Oncorhynchus Clarki Lewisi) In The Colville National Forest, Washington, Forrest Michael Carpenter

Dissertations and Theses

Climate change and anthropogenic effects have vastly reduced Westslope Cutthroat Trout (Oncorhynchus clarki lewisi, WCT) habitat throughout their range, including the Colville National Forest in northeastern Washington where this study was conducted. Many native salmonid populations have declined in abundance since the early 1900s due to a variety of climate- and human-driven forces. Westslope Cutthroat Trout are especially sensitive to habitat loss or degradation and to climate change. Together, climate change, habitat degradation, and non-native salmonid invasions are contributing to increasingly fragmented WCT populations. Ongoing and predicted future warming trends are expected to further fragment these populations and …

Gonadal Intersex In Teleosts: Mechanisms, Molecular Biomarkers And Diagnostic Assays, Ahmed M.E. Abdel-Moneim Mohamed

Open Access Dissertations

Natural and synthetic estrogenic and androgenic compounds are continuously released into aquatic ecosystems. Exposure of teleost fishes to these contaminants can negatively impact sex differentiation and reproductive output. Specifically, development of gonadal intersex in gonochoristic (fixed sex) fish species has been studied extensively in relation to exposure to this class of compounds. The main objectives of this dissertation were to: 1) conduct field and laboratory studies to investigate the molecular signaling pathways behind the development of gonadal intersex; and 2) establish molecular biomarkers and assays for testing the ability of environmental pollutants to develop this condition using a battery of …

Bloom Or Bust: Retrospective Analysis Of The Giant Jellyfish, Nemopilema Nomurai (Scyphozoa: Rhizostomeae), Ecology In The East Asian Marginal Seas, Naomi Yoder Dec 2016

Bloom Or Bust: Retrospective Analysis Of The Giant Jellyfish, Nemopilema Nomurai (Scyphozoa: Rhizostomeae), Ecology In The East Asian Marginal Seas, Naomi Yoder

Master's Theses

The Giant Jellyfish, Nemopilema nomurai, is a large-bodied bloom-forming jellyfish that occurs in the semi-enclosed basins of the East Asian Marginal Seas. N. nomurai has bloomed more frequently in the past 20 years than in any period previously recorded. In Japan, recent N. nomurai blooms were responsible for millions of dollars in lost revenue and equipment damage to commercial fisheries alone. This study statistically analyzed 21 environmental factors in connection with N. nomurai occurrence (using occurrence as a proxy for blooms). Eight factors resulted in a statistically significant or marginally significant (p ≤ 0.10), linear or non-linear relationship with …

Impact Of Environment And Ontogeny On Relative Fecundity And Egg Quality Of Female Oysters (Crassostrea Virginica) From Four Sites In Northern Chesapeake Bay, Hl Glandon, Ak Michaelis, Et Al, Kimberly S. Reece, Et Al

VIMS Articles

Resource allocation to reproduction is a primary physiological concern for individuals, and can vary with age, environment, or a combination of both factors. In this study we quantified the impact of environment and individual age on the reproductive output of female oysters Crassostrea virginica. We determined the relative fecundity, egg total lipid content, and overall and omega- 3/omega-6 fatty acid signatures (FAS) of eggs spawned by female oysters over a 2-year period (n = 32 and n = 64). Variation was quantified spatially and ontogenetically by sampling young and old oyster populations from two rivers in Chesapeake Bay, totaling four …

Regional Recruitment Dynamics And Seasonal Ecology Of Juvenile Bluefish (Pomatomus Saltatrix), David G. Stormer Nov 2016

Regional Recruitment Dynamics And Seasonal Ecology Of Juvenile Bluefish (Pomatomus Saltatrix), David G. Stormer

Doctoral Dissertations

Recruitment in fishes, defined as the survival of a cohort through the first year of life, can be highly variable and affected by small changes in biological and physical factors. Much of the historical focus into the sources of recruitment variability has concentrated on the larval stage, but recent attention has shifted to the relatively longer juvenile period. Spawning behavior that results in the production of multiple cohorts over time and space within a year-class may dampen recruitment variability by decreasing natural mortality risk. The bluefish (Pomatomus saltatrix) is a migratory marine species that produces multiple cohorts of …


Early Nutritional Programming To Enhance The Utilization Of Plant Based Diets In Fish (Largemouth Bass, Micropterus Salmoides), Maya Rene Jackson, Cora Teets, Amit Kumar Yadav, Waldemar Rossi Nov 2016

Early Nutritional Programming To Enhance The Utilization Of Plant Based Diets In Fish (Largemouth Bass, Micropterus Salmoides), Maya Rene Jackson, Cora Teets, Amit Kumar Yadav, Waldemar Rossi

Posters-at-the-Capitol

Aquaculture has been the fastest growing animal food-producing sector for over half a century. Sustainable aquaculture should include replacement of fish-based feed sources by plant-based ingredients. However, this approach is often impeded by poor growth in carnivorous fish such as largemouth bass (LMB, Micropterus salmoides) fed high levels of plant-based protein. Therefore, our overall goal of the present work was to develop alternative methods of utilizing the plant-based diets (PBD) for sustainable LMB production. When fish is exposed to PBD early in their life, they may accept them more efficiently at later stages (so called Nutritional Programing, NP). Therefore, …


Ecological Consequences Of Lost Anadromous Forage Fish In Freshwater Ecosystems, Steven R. Mattocks Nov 2016

Ecological Consequences Of Lost Anadromous Forage Fish In Freshwater Ecosystems, Steven R. Mattocks

Masters Theses

Beginning in the early 1600s, dam construction in New England obstructed anadromous fish access to spawning grounds during migration. As a result, anadromous forage fish populations have declined, which has impacted freshwater, marine, and terrestrial ecosystems. To determine the impacts of dams on anadromous forage fish and freshwater ecosystems, I used historical and current data to estimate population changes in alewives (Alosa pseudoharengus) from 1600-1900. A significant reduction in spawning habitat occurred in New England as a result of 1,642 dams constructed between 1600 and 1900, resulting in 14.8% and 16.6% lake and stream habitat remaining by 1900, …


River Herring Conservation In Freshwater: Investigating Fish Reproductive Success And The Educational Value Of Citizen Monitoring Programs, Meghna Marjadi Nov 2016

River Herring Conservation In Freshwater: Investigating Fish Reproductive Success And The Educational Value Of Citizen Monitoring Programs, Meghna Marjadi

Masters Theses

Over the last century anadromous alewife (Alosa psuedoharengus) and blueback herring (Alosa aestivalis), collectively called river herring, suffered drastic declines throughout their range from Newfoundland (Canada) to North Carolina (USA). A 2011 petition to include river herring in the Endangered Species Act (ESA) was rejected, partly due to inadequate information towards identifying coast-wide population status. Additionally, knowledge gaps were identified with basic ecology of the river herring life cycle in freshwater, including species reproductive strategies. In Chapter 2, I investigated how body size, spawning arrival time, and sex influence river herring reproductive success. I collaborated with …


Whiting Events Off Southwest Florida: Remote Sensing And Field Observations, Jacqueline Long Nov 2016

Whiting Events Off Southwest Florida: Remote Sensing And Field Observations, Jacqueline Long

USF Tampa Graduate Theses and Dissertations

“Whiting” is a term used to describe a sharply defined patch of water that contains high levels of suspended, fine-grained calcium carbonate (CaCO3). These features are named for their bright (at times white) appearance when compared to surrounding waters, and have been found to occur globally, persisting for multiple consecutive days. Although whitings have been widely studied using chemical, biological, geological, and physical techniques, there has been little effort to document their spatio-temporal distributions in a systematic way, not to mention the lack of consensus on what generates whitings and allows them to persist for days to weeks …


Fish Names Variability Traces The Geo-Historical Dynamics Of Moroccan Fishermen Communities, Hicham Masski, Abdelaziz Ait Hammou Nov 2016

Fish Names Variability Traces The Geo-Historical Dynamics Of Moroccan Fishermen Communities, Hicham Masski, Abdelaziz Ait Hammou

Journal of Ecological Anthropology

Fish vernacular names in Morocco needs a structuring system. Though used widely, these names are highly variable and do not necessarily meet trade requirements. The 138 species considered in this study have 691 vernacular names and the vernacular names lists of the 16 study sites show large disparities. The most part of this variability is of linguistic origin coming from four geographic regions and thus cultural groups. Even if possible, the adoption of a unique standard, which is the goal of the national fisheries regulation authorities, might encounter resistance to its dissemination throughout fishermen and the local population.


Penobscot River Restoration, Catherine Schmitt Nov 2016

Penobscot River Restoration, Catherine Schmitt

Maine Sea Grant Publications

BETWEEN THE HEAD of tide above Bangor to where it widens into the bay at Searsport, the Penobscot River shifts from a flowing freshwater waterway banked by cedar and pine to a brackish, wave-lapped marsh with a rocky shoreline. In this estuary, salt concentrations fluctuate as the winds and tides push sea water and sediments back and forth. The estuary and the river that feeds it have taken on a new character recently, and have become an international example of watershed restoration. Despite two centuries of intensive timber harvesting and pulp and paper manufacturing, and the construction of hundreds of …

Policy On The Application Of Fish Size Limits In Western Australia, Western Australia. Dept. Of Fisheries

Fisheries management papers

Fisheries managers can utilise a range of different types of management tools to assist with the sustainable management of fish stocks and to achieve other fisheries management objectives. For commercial fisheries these types of tools may include input controls (e.g. a limit on the number of operators, explicit effort limits and gear restrictions) and output controls (e.g. total allowable catches, individual catch quotas) or spatial and temporal restrictions. Recreational fisheries often have daily bag limits and possession limits as quasi output controls, while seasonal or other temporal closures can operate as input controls and be a component of limiting total …
