How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a qualified veterinarian specialising in fish health with a focus on pathology. My PhD thesis addressed the impact of harmful algal blooms & gelatinous zooplankton on salmonid gill health, including the role microbial communities play in gill disease. My more recent focus is in aquatic animal health for both fisheries and aquaculture, studying emerging disease and host response through histopathology, molecular investigation, and application of epidemiological principles.
Cnidarian jellyfish are pest species of marine aquaculture, with their acute impacts well documented in farmed fish, particularly affecting the delicate gill tissue. Less is known about subsequent consequences of exposure, including their association with secondary bacterial infections. The aim of this study was to identify whether potentially path...
Gelatinous plankton present a challenge to marine fish aquaculture that remains to be addressed. Shifting plankton distributions, suggested by some to be a result of factors such as climate change and overfishing, appear to be exacerbated by anthropogenic factors linked directly to aquaculture. Fish health can be negatively influenced by exposure t...
An unusual condition affecting market size rainbow trout was investigated. This condition was prevalent for several years at low levels but affected a large proportion of stock during 2018 and 2019. Chronic fibrosis affecting cranial tissues and the jaw was observed in samples collected in 2018. A larger sampling was then conducted in 2019 to inves...
Background Understanding the influence of methodology on results is an essential consideration in experimental design. In the expanding field of fish microbiology, many best practices and targeted techniques remain to be refined. This study aimed to compare microbial assemblages obtained from Atlantic salmon ( Salmo salar) gills by swabbing versus...
The gill of teleost fish is a multifunctional organ involved in many physiological processes, including protection of the mucosal gill surface against pathogens and other environmental antigens by the gill-associated lymphoid tissue (GIALT). Climate change associated phenomena, such as increasing frequency and magnitude of harmful algal blooms (HAB...
Covers the competencies necessary to assure the highest quality of aquatic veterinary services Fundamentals of Aquatic Veterinary Medicine provides systematic, highly practical guidance on the treatment of aquatic mammals, amphibians, fish, and invertebrates in veterinary practice.

This is the supplementary table for the publication "Impacts of jellyfish on marine cage aquaculture: an overview of existing knowledge and the challenges to finfish health". This table details the known cnidarian jellyfish of concern to aquaculture, and the impact of their exposure on fish health.
