Enriched rearing environment enhances fitness-related traits of salmonid fishes facing multiple biological interactions
To improve stocking success in threatened populations, captive-reared animals are often familiarized to natural environment. However, whether such actions improve ability to cope with multiple biological interactions, such as competition, predation and parasitism that impose contradicting pressures...

Salmon with different backgrounds of enrichment and parasite infection (eye fluke Diplostomum pseudospathaceum) were released to semi-natural ponds and monitored for activity, growth and predation susceptibility. Fish from enriched rearing showed lower short-term activity and higher short-term growth, suggesting that they coped better with novel conditions.

Importantly, parasitism did not remove the positive effect of enrichment on growth, although the infection decreased both short-term and long-term growth and survival. These results suggest that enriched rearing can enhance fitness-related traits of stocked fish particularly during the critical early days, which can have important implications for stock enhancement activities. peerReviewed Article in Journal/Newspaper Atlantic salmon Salmo salar JYX - Jyväskylä University Digital Archive |
