Dr Tamsyn Uren Webster and co-authors have recently developed a novel qPCR assay to detect and quantify Nucleospora cyclopteri in lumpfish. This novel assay identified high prevalence of the infection among asymptomatic fish. All analyzed tissues were affected, including blood, suggesting systemic infection. Asymptomatic lumpfish had

Salmon microbiome is sensitive to environmental factors during early life. For fish farmers this means early rearing condition affect the microbiome development and potentially the health of the fish throughout life. This exciting new study by Dr Tamsyn Uren Webster and co-authors opens an exciting path of future

A veterinarian at Swansea’s Centre for Sustainable Aquatic Research has pioneered the use of a non-destructive method to assess the health of lumpfish broodstock. Utilising his experience with ornamental fish in public aquaria, CSAR’s consultant veterinarian, Dr Richard Lloyd, has adapted the use of laparoscopy (keyhole surgery)

This new study identifies two genes in Nile tilapia related to the expression of stress in crowded environments: sstl and fosab. This is good news for breeders as it might be possible to selectively breed fish that perform better under crowded conditions. Figure 1. Experimental set up
