Some Aspects Of The Biology Of Monogenean (Platyhelminth) Parasites Of Marine And Freshwater Fishes, Graham C. Kearn

Harold W. Manter Laboratory of Parasitology: Library Materials

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 …

Effect Of Stocking Biomass On Solids, Phytoplankton Communities, Common Off-Flavors, And Production Parameters In A Channel Catfish Biofloc Technology Production System, Bartholomew W. Green, Kevin K. Schrader, Peter W. Perschbacher

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

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 …

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, …

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 …

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 …

Distribution And Elimination Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) By Sea Lamprey (Petromyzon Marinus) And Non-Target, Rainbow Trout (Oncorhynchus Mykiss) And Lake Sturgeon (Acipenser Fulvescens), Michael W. Le Clair

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 …

Connecting Model Species To Nature: Predator-Induced Long-Term Sensitization In Aplysia Californica, Maria J. Mason, Amanda J. Watkins, Jordann Wakabayashi, Jennifer Buechler, Christine Pepino, Michelle Brown, William G. Wright

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.

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 …

Ba/Ca Ratios In Otoliths Of Southern Bluefin Tuna (Thunnus Maccoyii) As A Biological Tracer Of Upwelling In The Great Australian Bight, Yu-Ting Lin, Chia-Hui Wang, Chen-Feng You, Wann-Nian Tzeng

Journal of Marine Science and Technology–Taiwan

The southern bluefin tuna (Thunnus maccoyii) is a longlived, large, and highly migratory marine fish in the Indian Ocean. They can live up to 40 years and migrate to the Great Australian Bight in the summer when 1-4 years old. The Great Australian Bight is characterized as the most productive coastal upwelling zone in southern Australia and is the largest area of cool-water carbonate sedimentation in the world. The barium (Ba) level is poor in the open ocean but rich in the upwelling area. This study used otolith Ba/Ca ratios as a natural tag to confirm that southern bluefin tuna …

Mortality In The Ocean - With Lessons From Hydrothermal Vents Off Kueishan Tao, Ne-Taiwan, Hans-Uwe Dahms, Jiang-Shiou Hwang

Journal of Marine Science and Technology–Taiwan

There is evidence of plankton mortality and extinction at various temporal and spatial scales induced by man-made pollution, or by natural causes (ageing, competition, predation, diseases, natural pollution). If mortalities take place at large scale they might become of environmental concern and may impact other biotic compartments including fisheries substantially. Such mortalities are a consistent phenomenon at time scales from geological mass extinctions to regularly occurring HABs, that appear to be increasing on a global basis. Several mass mortalities might have escaped our notice for their patchy and erratic occurrences. This also holds for mortalities caused by hydrothermal vents (HVs) …

Wuhanlinigobius, a new genus of Hemigobius generic group would been established and assigned from Mugilogobius polylepis Wu and Ni, 1985. Mugilogobius polylepis has been regarded as belong to genus Eugnathogobius based on lacking head pores and representing longitudinal sensory papillae in previous taxonomic study. However, we compared the osteological features of Mugilogobius polylepis Wu and Ni, 1985 and Eugnathogobius microps Smith, 1931 as well as the molecular phylogenetic analysis based on the mtDNA ND5, Cyt-b genes and D-loop region. The molecular phylogenetic tree including 9 related Hemigobius generic group reveal that this new genus represents an independent clade which is …

Does High Organic Matter Content Affect Polychaete Assemblages In A Shenzhen Bay Mudflat, China?, Li-Zhe Cai, Jiang-Shiou Hwang, Hans-Uwe Dahms, Su-Jing Fu, Xin-Wei Chen, Chen Wu

Journal of Marine Science and Technology–Taiwan

Coastal areas are the first marine systems being impacted by anthropogenic pollution and eutrophication. Organic matter poses a particularly negative impact on the environment due to its oxygen depleting and eutrophying effects. Shenzhen Bay mudflat contains rich organic matter. Here, we compare changes of polychaete assemblage parameters on seasonal data obtained from a Shenzhen Bay mudflat in a three-year study. The results based on the seasonal and spatial variations of polychaete species number, density and biomass, ShannonWiener diversity index, evenness index and richness index confirmed that high organic matter content impacted their distribution. A significant negative correlation between the density …

Decadal Variation Of Wintertime Sea Surface Temperature In The Taiwan Strait, Yi-Chun Kuo, Ming-An Lee

Journal of Marine Science and Technology–Taiwan

Long-term advanced very-high-resolution radiometer (AVHRR) data with a resolution of 0.04° provided clearer views of sea surface temperature (SST) warming and variation associated with ENSO in the Taiwan Strait (TS) during wintertime (1981-2013). Over the 33 year period, the spatial average of winter SST warming in the TS reached to 3°C. From 1981- 2001, the SST exhibited an increasing trend, with the fastest warming taking place from 1991-2001 after which it seemed to pause. From 2002-2012, the SST showed a cooling trend (-0.08°C/yr). Spatial variation of the warming was distinct, with the highest values concentrated in the winter fronts region, …
