The Impact Of Multiple Nursery Areas On The Population Structure Of Atlantic Menhaden, Brevooria Tyrannus, Kristen A. Anstead
OES Theses and Dissertations
Understanding the population structure and patterns of connectivity in marine fishes is essential when making predictions about a species' resiliency and persistence in an increasingly changing environment. The Atlantic Menhaden Brevoortia tyrannus is a clupeid that plays a critical role in the marine food web and supports one of the largest fisheries on the US East Coast. In addition to a decrease in overall numbers and spawning stock biomass, recruitment levels have remained low since the 1990s. Menhaden use numerous estuaries along the Atlantic coast for juvenile development before recruiting to the adult population and the contribution of each of …

Steps Towards Successful Cryopreservation Of Fish Gametes: Improving Laboratory Protocols In The Zebrafish Model To Increase Gamete Viability And Efficiency, Megan Chastain
EWU Masters Thesis Collection
Cryopreserervation is a powerful tool for the long term storage of genetic material from endangered species. While mammalian gametes have long been freezable, eggs and embryos from fish have yet to be successfully frozen. Furthermore, protocols for freezing fish sperm have low success rates. In an effort to overcome the limitations in gamete manipulation currently impeding successful fish gamete cryopreservation, I outline two experiment using zebrafish (Danio rerio) as a model for freshwater fish species. First, I attempted to extend working time in both eggs and sperm by incubating the gametes in rainbow trout oviductal fluid (RTOF), RTOF + HEPES, …

Winter Survival Strategies Of Benthic Invertebrates In Temporary Habitats In A Northern Minnesota Lake, Cal Oldenburg
Journal of Earth and Life Science
During the winter months in the northern hemisphere, above 40 degrees latitude, a freezing event occurs that can last several months. Some lakes may have large portions of the shallow littoral zone frozen completely solid down into the sediments. Invertebrates affected by these events have developed survival strategies to cope with the harsh environment. The two main strategies for invertebrates in these areas are to either migrate to a different area and recolonize the original area when it becomes available again, or to burrow into the sediments and withstand the freezing. A 1- month study took place on Lake Bemidji …

Phenology Of Annulus Formation In Walleye And Smallmouth Bass Otoliths, Brianna J. Graff, Daniel J. Dembkowski, Melissa R. Wuellner
Natural Resource Management Faculty Publications
Walleye Sander vitreus and smallmouth bass Micropterus dolomieu were sampled monthly (May-October) from Lake Sharpe, South Dakota during 2006 and 2007 to estimate the timing of otolith annulus formation and to evaluate the influence of fish age, sex, and sample location (walleye only) on the timing and detection of annulus formation. Timing of annulus formation was evaluated using marginal increment analysis. Walleye samples were stratified by age, sex, and sample location (i.e., upper and lower Lake Sharpe) and smallmouth bass samples were stratified by age and sex. Monthly mean marginal increment measurements for both species generally increased from May to …

Theses and Dissertations (Comprehensive)
The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), has been highly successful in the control of sea lamprey (Petromyzon marinus) populations in the Great Lakes. Treatments with TFM involve applying it to streams, where it targets larval sea lamprey which live burrowed in the stream substrate. While the toxic mechanism of TFM has been elucidated, and its effects on sea lamprey described, its effects on non-target fish species such as rainbow trout (Oncorhynchus mykiss) and lake sturgeon (Acipenser fulvescens) are not as well understood. The present work demonstrated that rainbow trout show a great capacity to detoxify the lampricide using glucuronidation, when exposed to …

Effects Of Predation Upon The Long-Spined Sea Urchin Diadema Antillarum By The Spotted Spiny Lobster Panulirus Guttatus, Meredith D. Kintzing, Mark J. Butler Iv
Biological Sciences Faculty Publications
Sea urchins, important herbivores in marine ecosystems, are strongly impacted by both the direct and indirect effects of predation, and the long-spined sea urchin Diadema antillarum is no exception. Once abundant on Caribbean coral reefs, D. antillarum populations were decimated by disease in the early 1980s, and only where their natural predators have been over-fished has D. antillarum recovery been observed. Spiny lobsters (Palinuridae) are predators of sea urchins, and although there are several species of spiny lobster in the Caribbean, only the spotted spiny lobster Panulirus guttatus is restricted to coral reefs where D. antillarum dwells. We investigated the …

Assessment Of Range, Habitat Use, And Diel Movement Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River Using Ultrasonic Telemetry, Sarah Mary Huck
Masters Theses
Flathead Catfish (Pylodictis olivaris) are one of the most targeted species for recreational and commercial fishing within the Mississippi River Basin. With heavy harvest pressure placed on many populations, proper management is crucial; however, the species range, habitat requirements, and diel movement patterns have rarely been investigated in free flowing rivers. Therefore, I used ultrasonic telemetry with active tracking to monitor movement and habitat use of 44 Flathead Catfish from August 2012 to December 2013 in the lower 280 km of the Wabash River. This system is ideal to evaluate broad and fine scale movement of Flathead Catfish …

The Reproductive Ecology Of Two Sympatric Demersal Fishes: The Naked Goby Gobiosoma Bosc And Striped Blenny Chasmodes Bosquianus, Rachel M. Tremont
Electronic Theses and Dissertations
The naked goby (Gobiosoma bosc) and striped blenny (Chasmodes bosquianus) are sympatric oyster reef fishes within temperate estuaries. The reproductive biology and early life history of these fishes were described during two consecutive spawning seasons from 2012-2013 in North Inlet, SC. The naked goby and striped blenny spawning seasons lasted for 21 weeks and 30 weeks, respectively, for 2012 and 2013. The naked goby spawning season began 3 weeks later than the striped blenny spawning season for both years. The temporal offset in the start of their spawning seasons may reduce competition for nest habitat between the two species. Naked …

OES Faculty Publications
Reproductive stage determination of male gonads has received sparse attention in fish biology literature with few studies detailing the building of gross anatomical- and histologic scales. The meagre (Argyrosomus regius) is one of the world's largest sciaenids and supports a significant regional fishery in European and North African waters whose reproductive patterns are yet to be fully investigated. In the present study, we derive a macroscopic grading system for meagre testis using semi-quantitative graphs that feature the testis variability along the species size range and time of the year. We then describe the histological stages and reproductive phases of male …

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, …

The effect of initial channel catfish (Ictalurus punctatus, Rafinesque, 1818) fingerling biomass (1.4, 1.8, or 2.3 kg m-3) on phytoplankton communities, common off-flavours and stocker catfish production parameters was evaluated in biofloc technology production tanks. Stocker catfish size (145.5–172.6 g fish-1) at harvest did not differ among treatments, but net yield increased linearly as initial biomass increased (R2 = 0.633). Mean total feed consumption increased linearly with initial catfish biomass (R2 = 0.656) and ranged from 10.7 to 15.8 kg m -3. Total suspended solids (TSS) in all treatments increased linearly …

Müller was the first to describe a monogenean, collected from the skin of the halibut (Hippoglossus hippoglossus). However, he regarded the parasite as a leech and named it Hirudo hippoglossi. It was not until 1858 that its status as a monogenean was established by van Beneden and named Epibdella (now Entobdella) hippoglossi. Van Beneden published a detailed and accurate description of the parasite and one of his excellent illustrations is reproduced here. Entobdella hippoglossi is one of the largest monogeneans, measuring up to 2 cm in length. It has a smaller relative, measuring 5 to …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Previous research on sensitization in Aplysia was based entirely on unnatural noxious stimuli, usually electric shock, until our laboratory found that a natural noxious stimulus, a single sublethal lobster attack, causes short-term sensitization. We here extend that finding by demonstrating that multiple lobster attacks induce long-term sensitization (>= 24 h) as well as similar, although not identical, neuronal correlates as observed after electric shock. Together these findings establish long-and short-term sensitization caused by sublethal predator attack as a natural equivalent to sensitization caused by artificial stimuli.

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Habitat disturbances affect wildlife populations through numerous mechanisms, and determining specific components of habitat disturbances affecting those populations is challenging. For example, a single disturbance can both change local habitat conditions and impose limitations on dispersal of animals. Both of these components can negatively affect biological responses, such as body condition, local movement patterns, or survival. Culverts are a habitat disturbance having both of these components. Culverts affect local habitat conditions by increasing sediment levels in downstream reaches, negatively affecting animals downstream of culverts. Culverts also impose limits on dispersal by blocking passage of stream organisms to upstream reaches, negatively …

Using Hydroxyapatite From Fish Scales To Prepare Chitosan/Gelatin/Hydroxyapatite Membrane: Exploring Potential For Bone Tissue Engineering, Yi-Cheng Huang, Hao-Wen Chu
Journal of Marine Science and Technology–Taiwan
Concerns have recently been raised about the treatment and use of hydroxyapatite, an important component of fish scale. The goal of this investigation is to evaluate the feasibility of using hydroxyapatite extracted from fish scale (FHAP) for bone tissue engineering. FHAP or sintered FHAP (sFHAP) was added to chitosan/gelatin (CS/GEL) mixture to prepare membrane. The effect of FHAP and sFHAP on the physical and chemical properties of the membrane and their affinities towards MG63 cells were studied. Accordingly, the prepared CS/GEL/FHAP membrane was characterized by FTIR (ATRFTIR) and SEM. Following sintering at 800°C for 4 h, the CS/GEL/sFHAP membrane had …
