The barbed wire jellyfish (Apolemia uvaria) has been a problem in Norway and Scotland.

Jellyfish on the menu at fish vets’ conference


New research on hydrozoan modelling features on the programme for the Fish Veterinary Society’s two-day spring conference to be held at the Norton House Hotel, Newbridge near Edinburgh on March 5 and 6.

Hydrozoans include Muggiaea atlantica, a micro jellyfish that caused considerable mortality in Scotland’s salmon farms in 2022 and 2023, and Apolemia uvaria, the “barbed wire” jellyfish that killed farmed salmon in Norway and Scotland last year.

The conference programme also features talks on new treatments and diagnostic approaches from across the globe, policy updates, sessions on trout, salmon, and African aquaculture, and an ornamental fish session with Dr Richmond Loh.

Life support

Day 1 features four sessions: Aquaculture in a changing environment; Diagnostics; Nutrition and novel approaches; and Treatments.

Presentations include “Life support interventions in net pen salmon farming” by Matt Clarke of Poseidon Ocean Systems, a Canadian company that produces aeration systems, among other things.

Cargill specialist Ashleigh Currie will talk about fish welfare in hatchery production.

Ashleigh Currie, technology application specialist at Cargill Aqua Nutrition (EWOS), will talk about the role played by the company’s health product, Dermic, in fish welfare in hatchery production, and Sean Black, senior scientific officer (aquaculture) at the RSPCA, will present on new insights and regulations in salmon and rainbow trout aquaculture welfare standards.

Act fast for discounts

Day 2 also has four sessions: Bacterial challenges and microbiome; Freshwater; Ornamental, genetics and reproduction; Policy updates, social science, and foreign aquaculture.

Speakers include Sandra Vesanto, veterinarian with Mowi Ireland, who will talk about experience with salmon rickettsial septicaemia (SRS) in that country, and Marius Takvam, a PhD researcher from the University of Bergen, who will present on new methodologies to better understand seawater tolerance in salmon smolts.
