SW: →Biological Containment: add info on triploidy and sterility
=== Biological Containment ===
The AquAdvantage salmon will all be female triploids (fish with three compete sets of chromosomes instead of two). TriploidyAccording to the EA: "The induction of triploidy is the only accepted method currently available for sterilizing fish on a commercial scale." However, the EA later notes that triploidy is not 100% successful at producing sterility in most causesGE fish. One potential problem is the possibility that some fish will not successfully become triploids. According to the EA, AquaBounty Technologies examined its effectiveness at inducing triploidy at its Prince Edward Island facility and found that it successfully averaged batches that are 99.8% triploids (with a range from 98.9% to 100%). AquaBounty Technologies plans to perform quality control tests, ensuring that "the likelihood of releasing a batch of eyed-eggs that are not at least 95% triploid is less than 0.05." In tests, results producing sterility by inducing triploidy is more successful in sterilityfemale fish than in males. (And all of the AquAdvantage salmon will be female.) Thus, AquaBounty is relying on the fact that all of the fish will be female as well as triploids to further prevent them from reproducing, should any of the fish actually be fertile.
=== Physical Containment ===
The application for commercialization of AquAdvantage is for only two facilities: one in Prince Edward Island, Canada (PEI) that will produce eyed-eggs, and one in Panama that will raise the GE salmon from the eyed-egg stage to market size.<ref>[http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/VeterinaryMedicineAdvisoryCommittee/UCM224760.pdf Environmental Assessment for AquAdvantage Salmon (Aqua Bounty Technologies, Inc.)
