Trout eggs resistant to VHS and IHN
Welcome to our website, we are the leading breeder and supplier of VHS-resistant and IHN-resistant trout eggs.
Our trout breed is well known for its high level of resistance to both the viral hemorrhagic septicemia (VHS) virus and the infectious hematopoietic necrosis (IHN) virus. Our team of experts utilizes the latest genetic selection methods and biosecurity measures to ensure that our eyed eggs are free from any virus contamination and are of the highest quality.
In this page we will explore how breeding for disease resistant is made on rainbow trout, and we will talk about the most common and most dangerous viruses for trout, as VHS and IHN, and how our company is developing trout resistant to these pathogens. We understand the impact that these diseases can have on your trout farming business and we are committed to helping you protect your investment.
The rhabdoviruses affecting trout
Trout are organisms susceptible to various diseases, including the VHS virus and IHN virus. Both pathogens are rhabdoviruses and are well known and illustrated by the scientific and technical literature of the sector.
VHS in rainbow trout
VHS is among the most studied and most widespread fish viral disease, especially in rainbow trout and can affect all life stages of this organism, which in general tend to develop immunity once the disease has passed. Morality can be devastating and put a company’s economic survival at risk. Some particularly sensitive strains of trout do not even guarantee that the acquired immunity is protective for a long time. There is no therapeutic remedy, and no commercial vaccines are available.
IHN in rainbow trout
IHN virus is the second rhabdovirus affecting trout. Generally, it is more typical of the juvenile phases, and its pathogenicity depends a lot on the size and age of the fish.
For this pathogen too, there are no remedies, nor effective vaccines.
Solutions to deal with these viruses
Since there are no effective remedies against VHS and IHN, and in consideration of the high economic impact of these pathogens, generally the solution has been to prevent entry of these diseases with strict biosecurity measures, and to eradicate (stamping-out) once the disease has entered the fish farm.
We too recommend that you always keep your guard up and prevent these viruses from infecting your fish. But in the unfortunate event that this happens, eradication is not always possible (for example in the case in which there is a complex hydrogeographic network). In these cases, the use of trout breeds resistant to VHS and IHN is the only viable solution
VHS-resistant trout and IHN-resistant trout
The development of trout resistant to VHS and IHN is the result of a selection research that lasted over twenty years. Our company has used an original system of breeding and crossing which, starting from Italian trout strains considered quite resistant to these viruses, has made it possible to develop new breeds whose resistance is considered very high, or even absolute, by fish farmers who have tested them in hostile environments. The original selection scheme has allowed the breed to be developed even in the absence of the virus (indirect selection) and without subjecting the broodstock candidates to the pathogen. In this way, by using a combination of genetic selection and strict biosecurity measures, we ensure that our eggs are of the highest quality and are free from any virus contamination.
The production and exportation of resistant eggs
After a long and laborious work, we are now ready to supply fellow farmers around the world with VHS and IHN resistant eggs.

At our breeding facility, we utilize the latest technology and equipment to ensure that our customers receive only the best products and services. We take great pride in our commitment to excellence and are dedicated to helping our customers succeed.
Resistance to other diseases and growth rate
Scientific research has shown that there is a genetic basis of resistance for most diseases affecting trout and fish in general. Beside resistance to viruses, we are working on other bacterial and parasites pathogens, so that we can offer trout eggs that have been selectively bred for their high level of resistance to a wide range of diseases, and still maintain a very good growth rate. Our company is involved for example in an important research project called Supertrout, which aims to develop trout genetically resistant to lactococcosis (Lactococcus garviae). Moreover, we are involved in other important research projects aiming to develop trout that are resilient to climate change, specifically those that can tolerate high water temperatures and resist proliferative kidney disease (PKD). We understand the urgency of this issue and are working to breed trout that can adapt to changing environments and remain healthy. Our team of experts is dedicated to identifying the genetic markers that enable trout to survive and thrive in warmer waters while resisting the harmful effects of PKD. By selecting the best specimens for breeding, we hope to create a new generation of trout that are more resilient and better equipped to handle the challenges of climate change.
