Abstract Throughout their life history, many animals transition among heterogeneous environments to facilitate behaviours such as reproduction, foraging and predator avoidance. The dynamic environmental biological conditions experienced by mobile species are integrated in the chemical composition of tissues, providing retrospective insight into movement. Here, we present a unique application nitrogen stable isotope clocks (‘isotopic clocks’), which integrate tissue turnover rates, consumer...
Understanding the fundamental reproductive biology of a species is first step toward identifying parameters that are critical for reproduction and development assisted techniques. Ejaculates were collected from aquarium (n = 24) in situ 34) sand tiger sharks Carcharias taurus. Volume, pH, osmolarity, sperm concentration, motility, status, morphology, plasma membrane integrity assessed each ejaculate. Semen with highest proportion motile was between April June both indicating seasonal cycle....
Piscine lactococcosis is an emergent bacterial disease that associated with high economic losses in many farmed and wild aquatic species worldwide. Early accurate detection of the causative agent piscine essential for management fish farms. In this study, a TaqMan quantitative polymerase chain reaction (qPCR) targeting 16S-23S rRNA internal transcribed spacer region was developed validated. Validation qPCR performed DNA previously typed L. petauri garvieae recovered from different hosts...
Aspergillosis is a common respiratory fungal disease in penguins managed under human care. Triazole antifungal drugs, including itraconazole, are most commonly used for treatment; however, itraconazole treatment failures from drug resistance becoming more common, requiring newer options. Voriconazole, triazole, being often. Until recently, no voriconazole pharmacokinetic studies had been performed penguins, leading to empiric dosing based on other avian studies. This has led increased...
Abstract Non-lethal methods for semen collection from elasmobranchs to better understand species reproduction has accompanied the development of artificial insemination. Ejaculates (n = 82) collected whitespotted bamboo sharks Chiloscyllium plagiosum 19) were assessed and cold-stored raw or extended at 4 °C. Females 20) inseminated with fresh 24–48 h paternity offspring determined microsatellite markers. Insemination females 10) resulted in 80 hatchlings 27.6% fertility. 24 4) 48 1) 17...
Aspergillosis is a common respiratory fungal disease in African penguins (Spheniscus demersus) under managed care, and treatment failures with itraconazole due to drug resistance are increasingly common, leading recent use of voriconazole. Empirical dosing voriconazole based on other avian studies has resulted adverse clinical effects penguins. The objective this study was determine oral pharmacokinetics (PK) (n = 18). Single once daily multiple doses 5 mg/kg were evaluated 4-mo washout...
Hyatt, M.W.; Anderson, P.A., and O'Donnell, P.M., 2016. Behavioral release condition score of bull bonnethead sharks as a coarse indicator stress. Capture handling stress can induce acidosis sometimes mortality in sharks. To approximate physiological after capture, fisheries researchers may use behavioral health assessment at release. The goal this study was to assess the efficacy (BRCS) estimating response. tested against changes acid-base, blood gas, metabolite analytes (pH, partial...
Fusarium spp. are saprobic moulds that responsible for severe opportunistic infections in humans and animals. However, we need epidemiological tools to reliably trace the circulation of such fungal strains within medical or veterinary facilities, recognize environmental contaminations might lead infection improve our understanding factors onset outbreaks. In this study, used molecular genotyping investigate clustered cases solani species complex (FSSC) occurred eight Sphyrnidae sharks under...
Preventative health care of elasmobranchs is an important but understudied field aquatic veterinary medicine. Evaluation inflammation through the acute phase response a valuable tool in assessments. To better assess bonnethead sharks ( Sphyrna tiburo ) under managed care, normal reference intervals protein electrophoresis (EPH) and proteins, C-reactive (CRP) haptoglobin (HP), were established. Blood was collected from wild caught, captive raised housed at public aquaria. Lithium heparinized...
Abstract: A captive adult crevice kelpfish, G ibbonsia montereyensis , developed a cutaneous mass, approximately 9 × 7 mm on the right side of head in an area nonscaled skin. Following surgical debulking, examination both impression smears and histologic sections tumor revealed predominant population round to spindloid polygonal cells with moderate amount lightly basophilic cytoplasm. The cytoplasm was filled round, variably‐sized reddish‐brown granules that often obscured nucleus. Nuclei...
Fundamental characteristics of the reproductive biology female sand tiger sharks Carcharias taurus are needed to understand periodicity, seasonality and environmental factors essential for reproduction in this iconic species. Animals managed care, such as aquariums, provide unique opportunity longitudinal study contrast situ that examined opportunistically, at a single point time. Additionally, comparison observations from successfully reproducing aquarium may help elucidate reasons lack...
Hyatt, M.W.; Anderson, P.A., and O'Donnell, P.M., 2018. Influence of temperature, salinity, dissolved oxygen on the stress response bull (Carcharhinus leucas) bonnethead (Sphyrna tiburo) sharks after capture handling.Capture handling can induce acidosis in sharks. This response, endured during commercial bycatch catch-and-release recreational fisheries, could be exacerbated certain environmental conditions. To assess influence changes acid-base, blood gas, metabolite analytes (pH, pCO2,...
Enteromyxum leei is an enteric myxozoan parasite of fish. This has low host specificity and the causative agent emaciation disease, known for heavy mortalities significant financial losses within Mediterranean, Red Sea, Asian aquaculture industries. The disease rarely been documented public aquaria and, to our knowledge, never confirmed USA. case report describes outbreak E. in a population mixed-species east African/Indo-Pacific marine fish undergoing quarantine at aquarium Four 16...
Sarcocystis falcatula is a well-known cause of fatal pneumonia in some birds, particularly Old World psittacines. Here we describe sarcosystosis due to S. 3 penguins (Family Spheniscidae) under managed care, including one African penguin (Spheniscus demersus), and two Southern rockhopper (Eudyptes chrysocome). Randomly distributed foci necrosis, inflammatory cell infiltrates, edema, variable numbers round elongated protozoal schizonts were observed sections lung. Protozoal organisms...

Elasmobranch cardiac anatomy and physiology has been well described; however, there is a dearth of information regarding disease. In support clinical case suspected congestive heart failure in 22-yr-old male sand tiger shark (Carcharias taurus), study was undertaken to identify feasible echocardiographic imaging planes preliminary indices for this species. Eleven echocardiograms were performed on six apparently healthy sharks. Echocardiographic parameters are presented using descriptive...
Abstract An aquarium-maintained female Red Irish Lord Hemilepidotus hemilepidotus presented with severe coelomic distension. The fish was anesthetized for ultrasonographic examination, which highlighted multiple cyst-like lesions in the liver and a distended ovary that filled follicles an inspissated egg mass. Multiple exploratory celiotomies were performed mass removal, biopsy, ovariosalpingectomy, body wall rupture repair. Fourteen weeks after original presentation, subsequent to 2 of...
