Antibiotic resistance research sounds warning for Vietnamese freshwater aquaculture

High levels of antibiotic resistance have been found in samples of the bacterium Aeromonas hydrophila extracted from farmed freshwater fish as part of a study in Northern Vietnam, underlining the need for more responsible disease management practices in the region.

Screening work sheds new light on disease risks in northeast Pacific salmon farming

The use of cutting-edge technology has helped Canadian researchers carry out some of the most detailed screenings to date of pathogens affecting Atlantic salmon aquaculture.

Antibiotic-resistant bacteria found in US supermarket shrimp raise red flags

Analysis of raw and cooked shrimp bought from supermarkets in Florida and Georgia has revealed the presence of a range of antibiotic-resistant bacteria (ARB) — a finding that could have implications for processing of imported shrimp products.

Mycobacteriosis could prove growing problem in aquaculture

Intensification of aquaculture and domestication of wild species are leading to an increased prevalence of mycobacteriosis in farmed aquatic invertebrates, according to a review of the disease’s emergence by an international team of researchers.

Microplastics harbor pathogens affecting farmed seafood

There is growing evidence that microplastic pollution in seawater could serve as reservoirs for pathogens in aquaculture, according to a University of Exeter review of current evidence in this emerging field.

Taming tilapia lake virus requires improved expert collaboration

Tilapia lake virus (TiLV) is an emerging threat to aquaculture, having been discovered in 2014 and now reported in 16 countries.

China making up for lost time in aquatic vaccine development

China is now responsible for over 70% of global farmed-fish production. Finding appropriate responses to fish disease has not been as rapid, researchers from Huazhong Agricultural University acknowledged — but new options in development suggest that the nation is fast catching up.

Why prophylactic use of antibiotics poses a problem for aquaculture

Aquaculture needs to change its “widespread and unrestricted” use of prophylactic antibiotics and accelerate the move toward vaccination and more sanitary practices globally, according to Felipe C. Cabello, MD, professor emeritus of microbiology and immunology at New York Medical College.
