Article Synopsis
- Recirculating aquaculture systems (RAS) use less water and produce less waste, but growing fish this way can lead to more diseases from germs.
- Scientists studied rainbow trout raised in RAS to find out about different germs affecting fish health, finding a mix of known and new germs that can cause problems.
- They created a special testing method to detect multiple germs at once, which could help predict and stop fish diseases that are causing high death rates.
Infection levels with the parasitic nematode Contracaecum osculatum in Eastern Baltic cod have increased in the last decades. Eastern Baltic cod is transport host for this parasite that has a high affinity for the liver of the fish. The liver is a highly vital organ and damage to the liver tissue can result in reduced functionality of the organ.

While the virus appears to be widespread in farmed rainbow trout, disease outbreaks associated with detection of PRV-3 have only occurred in recirculating aquaculture systems, and has predominantly been observed during the winter months. To explore the possible effects of water temperature on PRV-3 infection in rainbow trout, an cohabitation trial was conducted at 5, 12, and 18°C.

In 2015, a new genotype of PRV (genotype 3, PRV-3) was discovered in Norway, and in 2017 PRV-3 was detected for first time in Denmark in association with complex disease cases in rainbow trout in recirculating aquaculture systems (RAS). To explore the epidemiology of PRV-3 in Denmark, a surveillance study was conducted in 2017 to 2019.

- Piscine orthoreovirus genotype 1 (PRV-1) is commonly found in farmed Atlantic salmon in northern Europe and has been detected in wild fish in Norway and Canada, but its impact on wild populations is not well understood.
- A survey conducted on 1,130 wild salmonids across various countries revealed the first instances of PRV-1 in wild fish from Denmark, Sweden, Faroe Islands, and Ireland, with prevalence rates varying by region.
- The study highlights the need for monitoring PRV-1 in wild fish populations, especially broodfish for restocking programs, due to the virus's geographical spread and genetic diversity.
