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

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 …

Assessing The Vulnerability Of Fishery Villages Influenced By Climate Change And Anthropogenic Activity In The Coastal Zone Of The Tamsui River, Sheng-Yuan Teng, Ming-An Lee, Jhen Hsu, Tzu-Ping Lin, Yu-Chen Lin, Yi Chang

Journal of Marine Science and Technology–Taiwan

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 …

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

Journal of Marine Science and Technology–Taiwan

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 …

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–Taiwan

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 …

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

Journal of Marine Science and Technology–Taiwan

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 …

Assessment Of Landform Changes In Baramarae Tidal Flat, Korea Using Combined Analysis Of Multi-Temporal Remote Sensing Images And Grain Size Measurement Data, Yeseul Kim, Dong-Ho Jang, No-Wook Park, Hee Young Yoo

Journal of Marine Science and Technology–Taiwan

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 …

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 …

The western rock lobster Panulirus cygnus (George) is taken by commercial and recreational fishers throughout its geographic range along the lower west coast of Western Australia. The main commercial fishery for P. cygnus is the West Coast Rock Lobster Managed Fishery (WCRLMF), which is Australia’s largest single-species fishery, currently worth about $400 million annually. Western rock lobster provides the basis for the economies of a number of coastal towns and also supports a recreational fishery.

Effective Tandem Hoop Net Sampling Effort For Evaluation Of Channel Catfish Populations In Reservoirs, Philip B. Malone

Theses and Dissertations from 2016

Channel Catfish Ictalurus punctatus have an important role in Arkansas’s commercial and recreational fisheries. This importance promoted sampling strategy investigations for obtaining information that assist with future management decisions. My study focused on determining effective sampling effort and sample size requirements needed for detecting changes in relative abundance within Channel Catfish populations, and explored relationships between catch per unit effort (CPUE) and reservoir habitat characteristics. My study was conducted during the spring of 2014 in six reservoirs (Lake Nimrod, Lake Overcup, Lake Catherine, De Queen Lake, Lake Erling, and Lake Columbia). General stock assessments consisting of length frequency distributions, growth …

Reproductive Characteristics Of Landlocked Fall Chinook Salmon From Lake Oahe, South Dakota, Kelsen L. Young, Michael E. Barnes, Jeremy L. Kientz

The Prairie Naturalist

Lake Oahe, South Dakota, USA, landlocked fall Chinook salmon (Oncorhynchus tshawytscha) reproductive characteristics were examined over a 27 year period, from 1988 to 2015. Mean total lengths of spawning females ranged from 665 mm (1995) to 812 mm (2015) with considerable year-to-year variation. Post-spawn female weights varied, ranging from 2.02 kg (2000) to 5.55 kg (2015), with an overall mean of 3.04 kg. Fecundity peaked at 4,555 eggs per female in 2003, which was just 3 years after a low of 2,011 eggs per female in 2000. Relative fecundity based on female weight was greatest at 1,211 eggs/kg …

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

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 …

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, …

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

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.

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 …

Changes In Sublethal Effects And Lead Accumulation In Acanthopagrus Latus Under Various Lead Concentrations And Salinities, Wen-Ching Tsui, Jiann-Chu Chen, Sha-Yen Cheng

Journal of Marine Science and Technology–Taiwan

This study investigated the sublethal concentration of lead and calcium levels in yellowfin seabream juvenile (Acanthopagrus latus) (4.367 ± 0.470 cm; 1.408± 0.478 g) following exposure to a series of lead concentrations at various salinities (0‰, 9‰, 17‰, 25‰ and 34‰). Yellowfin seabream juveniles exposed to 17‰ salinity were the most tolerant to lead. After 96-h, the 50% lethal concentration (LC50) values were 0.33, 1.43, 3.78, 2.32 and 1.46 mg Pb2+ /L following exposure to 0‰, 9‰, 17‰, 25‰ and 34‰ salinities, respectively. The 6-, 12-, 24-, 48- and 96-h LC50 for fish exposed to 17‰ salinity were 124.67, 33.02, …

A Lota Lota Consumption: Trophic Dynamics Of Non-Native Burbot In A Valuable Sport Fishery, Stephen L. Klobucar, W. Carl Saunders, Phaedra Budy

Watershed Sciences Student Research

Unintentional and illegal introductions of species disrupt food webs and threaten the success of managed sport fisheries. Although many populations of Burbot Lota lota are declining in the species’ native range, a nonnative population recently expanded into Flaming Gorge Reservoir (FGR), Wyoming–Utah, and threatens to disrupt predator–prey interactions within this popular sport fishery. To determine potential impacts on sport fishes, especially trophy Lake Trout Salvelinus namaycush, we assessed the relative abundance of Burbot and quantified the potential trophic or food web impacts of this population by using diet, stable isotope, and bioenergetic analyses. We did not detect a significant …

Intensive, Regular Sampling And Removal Of Modest Numbers Of Fishes Shows No Measurable Impact On Fish Populations In Three Streams Of North Georgia, Steven L. Powers

Southeastern Fishes Council Proceedings

Recent publications and restrictions on collecting by state fish and game managers indicate a growing concern regarding the impact of field sampling on native fish populations. To evaluate the validity of these concerns, data from five life-history studies conducted in Cherokee County, Georgia were examined to test the hypothesis that regular sampling has a negative impact on fish populations. Number of individuals collected was divided by time collecting to calculate catch per unit effort (CPUE) as an indicator of relative abundance for each species. The collecting sequence (i.e. the number of times a species had previously been sampled) was regressed …
