Nguyen et al. describe #Dermisichthinium_pseudosporum, a novel #Cyst-forming #Parasitic #Dinoflagellate from a distinct lineage, infecting #FreshwaterFish in WI, USA. This highlights the need for accurate #Diagnostics in #FishHealth. bit.ly/dao_164_67

Analysis of wild juvenile #Salmon #Monitoring data both during and after removal of intense finfish #Aquaculture operations in #BritishColumbia #Canada, shows no change to #SeaLice #Infestation #Prevalence or #Intensity between 2016 and 2024. bit.ly/dao_163_107

The #Neurotoxin #DomoicAcid (#DA), produced by #HarmfulAlgalBlooms, accumulates in #SeaStar digestive tissue. Experimental exposure to a DA analog had immediate effects on sea stars: deflating arms, prolonging righting time, and curling up. bit.ly/dao_163_95

Retrospective analysis of #Erysipelothrix_rhusiopathiae in #Cook Inlet, #Alaska found infections in 28.6% of #Beluga necropsied during 2006–2023, but only rare detection in other species or the environment. Several lineages were sequenced. bit.ly/dao_163_1

A #FranciscanaDolphin #Pontoporia_blainvillei stranded in northern #SãoPaulo, #Brazil, was subject to #Necropsy, #Histopathology and #Radiography, presenting a likely adrenal #NeuroendocrineTumor and #Lumbar #AnkylosingSpondylosis. bit.ly/dao_163_17

Spirometry accurately assesses #RespiratoryHealth in #StrandedDolphins. This rapid, non-invasive tool enhances diagnostics and boosts survival during rescue efforts, offering new hope for #MarineMammal #ConservationScience 🐬 🌊 bit.ly/dao_161_113

#ViralHemorrhagicSepticemiaVirus #VHSV was detected and identified in healthy #BastardHalibut #Paralichthys_olivaceus on the east coast of #China through virus isolation, #qRT-PCR, and conventional #RT-PCR followed by #Sequencing. bit.ly/dao_161_69

High adult #PacificOyster #Mortality associated with #Vibrio_aestuarianus reduced the effectiveness of #SelectiveBreeding for resistance against the #OsHV-1 #Microvariant in #Aquaculture in #RíaDeArousa (#Galicia, #Spain). bit.ly/dao_161_55

Parasites such as #Bonamia_exitiosa are capable of devastating #Oyster populations and identifying #Carriers can help minimize the spread of #Disease. Could the widely distributed #PacificOyster have aided in the #Dispersal of Bonamia? bit.ly/dao_161_39

Water #OxygenContent is the primary limiting factor for #GillFunction. Fish capable of adaptive #Interlamellar #Hyperplasia (reversible remodeling) appear to be particularly vulnerable in conditions of #Aquatic #Hypoxia. bit.ly/dao_161_29

Craig et al. measured temperature dependent velocities and #ThermalTolerance of the infective stage of an #Amphibian #Chytrid pathogen, finding evidence of #ThermalAcclimation responses at rapid time scales predicted by #MetabolicTheory. bit.ly/dao_160_101

#Nitrogen #GasBubble #Disease occurred in 2 #GiantSalamanders in an #Aquarium tank. Our case report describes the #ClinicalSigns, #Macroscopic and #Histopathological findings in the salamanders and case #Etiology. bit.ly/dao_160_95

Over 33 years, #MarineMammal #Necropsies from the #Croatian #AdriaticSea coast showed intentional, human-inflicted #Injuries in 13/311 cases. We recommend educational campaigns and stronger legal penalties to discourage such criminal acts. bit.ly/dao_160_75

In Sep-Dec 2023, an #HPAI-H5N1 #Outbreak caused high #Pinniped #Mortality in #Uruguay (92.4% dead of 2713 stranded), and a 15% loss of the #SouthAmerican #SeaLion population. Of 159 swabs, 22.6% tested positive, most unidentified pinnipeds. bit.ly/dao_160_65

Western et al. report a #Rescue effort and #Necropsy findings in a live-stranded #Manatee from #Alabama waters; #CauseOfDeath was multifactorial, including #ColdStress, #HeartFailure, and a plastic bag stuck in the esophagus. bit.ly/dao_160_57

Barrett et al. describe #Polycystic #Ovarian #Disease in captive #CownoseRays across multiple institutions, provide insights into #Diagnosis and #Pathogenesis, and suggest future research into predisposing factors and treatments. bit.ly/dao_160_47
