Breeding for improved disease resistance
in European farmed fish
Identifying genetic factors of disease resistance
Improving the genetic resistance of farmed fish to some of the most problematic infectious diseases in European aquaculture is the goal of Work Package 1 (WP1) of the FISHBOOST project.
In year 1, a series of disease challenge experiments have been undertaken on populations of juvenile fish with known pedigree. The data collected from these challenges will be used to quantify the genetic variation in disease resistance in these populations, and to develop genetic markers that can be used to find underlying resistance genes and to breed more resistant stocks. Infectious disease outbreaks present one of the biggest threats to reliable and sustainable production of finfish in Europe. During such outbreaks, typically some fish in a population are much worse affected than others. This variation is due to both genetic and environmental factors. Quantifying and characterising the genetic factors can lead to development of more resistant stock via selective breeding programmes. Read more.
