Diversity of sea bass pathogen strains highlights challenge in Mediterranean aquaculture

A new study analyzing three strains of the bacterium Vibrio harveyi found among farmed sea bass in the Mediterranean has underlined the diversity of the pathogen, which poses a severe threat to the region’s aquaculture.

Sea bass immunity to parasitic disease

Sea bass immunity to parasitic disease could lead to new treatments

No effective licensed therapies exist against amyloodiniosis, a disease of fish species caused by Amyloodinium ocellatum (AO) ectoparasites. However, new research has shown that European sea bass (ESB) can develop specific immunity to the disease, which could in turn lead to the development of vaccines.

Diagnostic approaches for fish disease

Advanced diagnostic approaches for fish disease are welcome, but sometimes simpler is better

With technologies for molecular diagnosis of fish disease increasingly available, sometimes simpler approaches that have great diagnostic power are being ignored.

Safety and welfare concerns drive shift to licensed anesthetic in Mediterranean aquaculture

Improving standards on Mediterranean fish farms is driving interest in Tricaine PHARMAQ — the only authorized fish anesthetic product.

Vaccines boost Greece’s seabass and seabream aquaculture — but challenges remain

Aquaculture in Greece has endured some ups and downs since its establishment in the 1980s, from the Greek financial crisis to the Covid-19 pandemic.

Producing healthy barramundi — one of sustainable aquaculture’s great hopes

Barramundi has much potential as a sustainable fish in the marine tropics — but health challenges remain for producers. Josh Goldman, CEO of Australis, explains his company’s approach.

Eastern Mediterranean sea bass more resistant to highly pathogenic virus strain

Eastern Mediterranean populations of sea bass showed three times the survival rate of Atlantic Ocean and Western Mediterranean stocks against a pathogenic strain of nervous necrosis virus (NNV) in a new challenge study.

Vaccine ‘work in progress’ in major aquaculture markets, Part 1: Sea bass

European sea bass aquaculture is centered on the Mediterranean basin, and there are a number of notable pathogens which can cause high mortality on production sites through direct and indirect effects.
