Genetic Study of Farmed Rainbow Trout in Norway
Author Information
Author(s): Kevin A Glover
Primary Institution: Institute of Marine Research, Norway
Hypothesis
Can genetic analysis identify the farm of origin for escaped rainbow trout?
Conclusion
The study found significant genetic variation among rainbow trout strains in Norway, aiding in the identification of escapees.
Supporting Evidence
- The study analyzed 35 escaped rainbow trout to determine their farm of origin.
- Genetic variability was significant across all samples tested.
- Self-assignment tests showed an overall correct assignment of 82.5% for the samples.
Takeaway
Scientists looked at the DNA of rainbow trout to figure out where some fish that escaped from farms came from.
Methodology
DNA was extracted from fin clips and analyzed using microsatellite loci to assess genetic variation.
Potential Biases
Potential bias in sampling as farms were not named for legal reasons.
Limitations
The study did not identify a single farm of origin for the escapees due to shared genetic material among the farms.
Participant Demographics
The study involved rainbow trout from multiple farms in Norway.
