A novel qPCR assay for the rapid detection and quantification of the lumpfish (Cyclopterus lumpus) microsporidian parasite Nucleospora cyclopteri

  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

Environmental plasticity and colonisation history in the Atlantic salmon microbiome: a translocation experiment

Environmental plasticity and colonisation history in the Atlantic salmon microbiome: a translocation experiment

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

Cortisol-Related Signatures of Stress in the Fish Microbiome

Cortisol-Related Signatures of Stress in the Fish Microbiome

  Cortisol – a stress related hormone, disrupts the gut microbiome in salmon. This can cause poor fish health – check out our new publicationby Dr Tamsyn Uren Webster and co-authors. This paper also highlights the value of using non-invasive faecal samples to monitor stress, and simultaneous

HOW KEYHOLE SURGERY IS IMPROVING LUMPFISH WELFARE AND PRODUCTION TECHNIQUES

HOW KEYHOLE SURGERY IS IMPROVING LUMPFISH WELFARE AND PRODUCTION TECHNIQUES

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)

The transcriptomic response to aggression and crowding in Nile tilapia aquaculture intensification

The transcriptomic response to aggression and crowding in Nile tilapia aquaculture intensification

  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

New findings about tilapia welfare

New publication from SMARTAQUA team suggests that stocking farmed tilapia at high densities could be beneficial to their welfare and make them less invasive should they escape. The study was published in the Royal Society Open Science in early December and looks into how crowding in Nile
