A new, cost-effective selective breeding method for improving how resistant salmon are to sea lice is being developed by a Scottish research consortium.

A veterinary scientist in the Faroe Islands has been credited with helping to halt the spread of Covid-19 in the archipelago by adapting tests previously used to detect infectious salmon anaemia (ISA).

Scotland’s salmon farming sector has welcomed the steps taken by industry regulators to adapt the rules governing sea lice treatments during the COVID-19 pandemic.

Emerging research has demonstrated that Ivermectin, which was previously used as a means of removing sea lice from farmed salmon, inhibits the causative virus for COVID-19 (SARS-CoV-2) in vitro.

Providing rainbow trout with enhanced oxygen and exercise levels leads to improved growth performance and cardiac health.

Researchers in Scotland are embarking on a project that aims to enhance the global aquaculture sector’s understanding and treatment of gill disease.

The levels of anti-sea lice medication residues in Norwegian farmed salmon and trout may be below the EU’s maximum residue limit (MRL), but a longer withdrawal period for emamectin should be considered.

A new device for improving fish welfare during the vaccination process has been launched by Socorex today.

Problems with sea lice in salmon farms are making it increasingly cost-effective to on-grow smolts past 100g in land-based systems, according to a new study.

Fish that are subjected to chronic exposure to microplastic fibres suffer from issues including aneurysms and gill damage, according to a new study.

Detailed analysis of big data has revealed that cleaner fish have highly variable - but generally poor - efficacy in terms of combating sea lice infestations in salmon farms.

Scottish salmon farmers have welcomed a new consultation on the merits of introducing legally binding rules to control the harvesting of wrasse for use as cleaner fish.

New research suggests that cleaner fish are nine times less effective at removing sea lice from salmon in pens surrounded by lice skirts, possibly due to the increased depth the salmon swim at in such pens.

Scotland's salmon farming sector had an average monthly survival rate of 98.60 per cent during 2019, according to the latest figures.

A new study suggests that environmental and dietary changes are the key factors explaining why numerous seemingly healthy farmed salmon die in the run-up to harvest.

Certain tilapia families have been shown to be completely resistant to tilapia lake virus (TiLV), offering hope that breeding programmes can combat one of the worst diseases to hit the global fish farming industry in rec…

A new tool that is designed to give salmon farmers advanced warning about outbreaks of sea lice and pancreas disease (PD) has been launched by Manolin today.

Benchmark Holdings, the aquaculture health, nutrition and genetics business, has raised £43 million, as it seeks to scale up its CleanTreat sea lice treatment system.

Claims that using cleaner fish to remove parasitic sea lice from farmed salmon can be economically or ethically justified are not backed up by “robust evidence” according to a new scientific report.

Researchers in the US have made a discovery which could help the trout farming industry’s battle against the mucosal parasite Ichthyophthirius multifiliis, commonly known as Ich, and other microbial threats to fish healt…
