ICELAND - An outbreak of Viral Hemorrhagic Septicemia (VHS) has been reported for the first time in Iceland this week.

The outbreak was detected in wild lumpfish (Cyclopterus lumpus) in Hafro Grindavik, Gullbringu, which were intended for use as broodstock for the breeding of cleaner fish.

In total, 5,145 kg of lumpfish were destroyed.

Following the announcement of the outbreak, Chile's Sernapesca issued Resolution 9844 which suspends the import of eggs from Iceland.

In the US, fish farmers are now able make use of a new quick reference guide which provides information on all approved drugs for use in aquaculture.

The guide, published by the US Fish & Wildlife Service’s Aquatic Animal Drug Approval Partnership Program, lists all currently approved drugs for use on aquaculture species. It also describes how each drug may be legally used (e.g., dose, concentration, duration) and under what circumstances (i.e., the specific disease or conditions).

In other news, researchers in Norway have undertaken the first ever study that highlights just how much phosphorus is consumed and wasted in the Norwegian aquaculture industry. 

The phosphorus contained in imported raw plant materials destined for fish feed production currently accounts for almost one-third of the phosphorus imported to Norway, and is larger than domestic fertiliser consumption.

In addition, fish farming is the largest source of phosphorus emissions, generating about 9,000 tonnes a year.

Researchers at the Norwegian University of Science and Technology and Nibio, the Norwegian Institute of Bioeconomy Research say that finding a way to reuse waste phosphorus could allow for new business opportunities as well as cut pollution from aquaculture.
