Oncorhynchus mykiss is a Pacific native and has been farmed since the 19th century. Today it is farmed in both fresh water and seawater around the world. Major centres of production are Europe and the Americas, with the greatest production being in Chile.
We are in the advanced stages of developing markers for selection of high fillet yield broodstock. These markers will allow breeders of any size to efficiently select the optimal animals from the natural variation within their strain, leading to more profitable offspring.
Work is also underway to develop markers for high muscle fibre number, which is an important biological determinant of growth rate flesh quality.
