Diagnosis of Mycobacteriosis in Cultured Hybrid Tilapia (Oreochromis spp.) in Trinidad and Tobago

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Mycobacteriosis is a significant disease in fish husbandry, with negative impacts on production facilities. Moreover, some Mycobacterium spp. that infect fish have zoonotic potential. Morbidity and mortality events at hybrid tilapia (Oreochromis spp.) farms in Trinidad and Tobago (T&T) associated with mycobacterial infections prompted a ...

Development and Validation of a Viability RT‐qPCR Assay for Detecting Infectious Spring Viraemia of Carp Virus (SVCV)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Spring viremia of carp virus (SVCV) is a contagious pathogen associated with significant mortality and economic losses in freshwater aquaculture. Although reverse transcription quantitative PCR (RT‐qPCR) enables rapid detection, it does not distinguish between infectious and non‐infectious viral particles, which may lead to overestimation of ...

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Unveiling coralline diversity of mesophotic rhodoliths in subtropical Japan, including new species of Sporolithon, emended genera Orientalilithon and Roseolithon (Corallinophycidae, Rhodophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract The mesophotic zone off Tanegashima Island (approximately 30–40 m deep) is a marine macroalgal hotspot in subtropical Japan; however, the taxonomic diversity of calcifying red algal community remains poorly understood. Our phylogenetic analyses based on psbA, rbcL, and COI‐5P gene markers disclosed the presence of at least 12 rhodolith‐forming
