Paracetic acid ‘very promising’ as treatment for amoebic gill disease

Paracetic acid ‘very promising’ as treatment for amoebic gill disease

Scientists looking into peracetic acid as an alternative to hydrogen peroxide for the treatment for amoebic gill disease (AGD) in farmed salmon have said initial results are very promising, but the treatment needs further optimisation before it can be used.

Salmon gut simulator to be used by feed ingredient maker Royal DSM

SalmoSim – the Scottish start-up company behind an Atlantic salmon digestion simulator – has secured a new contract with Dutch nutrition, health and bioscience multinational Royal DSM to support the development of its sustainable aquaculture feed ingredients offering.

Taking a deep dive into salmon production in RAS

Taking a deep dive into salmon production in RAS

The growing importance of recirculating aquaculture systems (RAS) for Scottish aquaculture has been explored in a two-day event organised by fish health and research company STIM.

Alternative ingredients make inroads into salmon feed

Alternative ingredients make inroads into salmon feed

Producers of Norwegian salmon feed have begun to use completely new ingredients, according to a report on raw materials for salmon and trout.

Researchers seek to put salmon back in the pink

Researchers seek to put salmon back in the pink

The colour of salmon fillets is one of the most important quality criteria and paler salmon with paler colour are downgraded, resulting in financial losses for fish farmers. Norwegian research institute Nofima wants to find out why some fish are paler, and what can be done about it.

Dead bacteria in the fish gut can originate from feed

Dead bacteria in the fish gut can originate from feed

The intestines of animals are teeming with bacteria, affecting how animals digest their food. Studying these microbes is therefore an interesting part of research when investigating the effects of feed on animals, including farmed fish. However, recent research sheds new light on the value of these studies.

Sterilised salmon 'perform just as well as fertile fish'

Sterilised salmon 'perform just as well as fertile fish'

Salmon made sterile by a method developed by Norwegian scientists perform at least as well as fertile fish in terms of growth and welfare, a study has shown.

PD vaccines linked to salmon deformity

PD vaccines linked to salmon deformity

Oil-based vaccines used to prevent pancreas disease (PD) in salmon can cause a deformity called cross-stitch vertebrae, Norwegian research institution Nofima says.

Nofima orders 20 mini-RAS to study intensive fish farming

Nofima orders 20 mini-RAS to study intensive fish farming

Norwegian aquaculture, fisheries and food research institute Nofima has ordered 20 small-scale fully automated recirculating aquaculture systems from Dutch supplier Landing Aquaculture BV.

Researchers win prize for reducing experiments on fish

Researchers win prize for reducing experiments on fish

Two scientists from Norwegian research institute Nofima have been awarded a prize for their efforts to advance strategies for reducing the number of laboratory animals in fish health studies.

Hydrolysed krill doubled smolt growth in first six weeks in sea

Hydrolysed krill doubled smolt growth in first six weeks in sea

Experiments conducted at Norwegian aquaculture research institute Nofima show that salmon smolts that eat feed containing hydrolysed krill will eat considerably more and their weight will increase during their first days in the sea.

British men more negative to fish farming than those in EU

British men more negative to fish farming than those in EU

Young British men are most negative about farmed fish, and they were also among those who know the least about aquaculture, a survey among residents of the United Kingdom, Italy, Spain, France and Germany has revealed.

AquaGen questions need for warm seas salmon

AquaGen questions need for warm seas salmon

Salmon egg producer AquaGen has challenged the necessity for “climate-robust” salmon to be bred to compensate for rising sea temperatures, pointing out that its own research shows .

Study finds ‘optimal’ current speed for RAS post-smolts

Study finds ‘optimal’ current speed for RAS post-smolts

The optimum velocity of water in recirculating aquaculture systems used for post-smolt salmon should be slightly above one fish body length per second, researchers in Norway have concluded.
