ANALYSIS - In this week's news round-up, a more natural method to protect fish from fanged parasites has been identified by researchers at James Cook University, Australia, writes Lucy Towers, TheFishSite Editor.

The researchers found that adding garlic as a supplement to fish diets kept fanged parasites away as well as improving the immune system.

Compared with other parasite treatment, garlic was happily accepted by the fish, helping to increase feed intake.

Parasites can severely compromise the welfare of fish farmed though aquaculture. Specifically, a monogenean flat-worm parasite, Neobenedenia sp., has caused severe problems for farmers rearing fish in tropical marine waters.

Fish farmers in the US may soon struggle to find fully legally registered aquaculture drugs if planned operational budget cuts for fiscal year - 2014 go ahead.

The Aquatic Animal Drug Approval Partnership (AADAP), which works on fish drug approval research, will lose 22 per cent of its funding and half of its staff if Congress pass the cuts.

The devastating affect would be a reduction in drug registrations in the US, leading to a limited choice for farmers needing to treat sick fish and eventually, it could lead to drug resistance in fish.

Norway experienced good salmon exports during August 2013, with a total value of NOK 3.3 billion, 31 per cent more than August 2012. The increase in value for the month was attributed to strong salmon prices.

In total, the country noted a value of NOK 4.7 billion for total fisheries exports in August, a 20 per cent increase from the same period last year.

Despite an overall increase across the sector, the export value of herring and mackerel fell during August 2013 by 18 per cent to a total of NOK 155 million.
