First study into GM Atlantic salmon mating reveals danger of escape to wild gene pool
Date:7/13/2011

sgenic counterparts in terms of a variety of spawning behaviours. Moreover, despite being less aggressive, non-transgenic male parr were also able to outperform their GM rivals in terms of spawning behaviour, and as a result, achieved higher overall fertilisation success.

"While the transgenic males displayed reduced breeding performance relative to their non-transgenic rivals they still demonstrated the ability to successfully participate in natural spawning events and thus have the potential to contribute modified genes to wild populations," said Moreau. While the study provides an estimate of breeding performance under only a single set of physical and demographic environmental conditions, it does mimic a likely invasion scenario where the genetic background of the transgenic population differs from that of the wild population.

"Our study provides the first empirical observations on the natural reproductive capacities of growth hormone transgenic Atlantic salmon," concluded Moreau. "While the resulting ecological and genetic effects of a transgene escape remain uncertain, these data highlight the importance of preventing reproductively-viable GM salmon from entering natural systems."
