Comparison of survival rates between domesticated and semi-native char using Bayesian multi-variate state-space model

Streams depleted of their native salmonid populations are often stocked with domesticated fish for supplementation. However, these domesticated salmonids have a lower adaptability to environmental conditions and thus have a lower survival rate than “native” salmonids. Recent studies suggest the stocking of “semi-native” strains of fish (hybrids between native males and domesticated females) as an alternative to domesticated fish. We evaluated...
