The aquatics lab was a facility on board the USS Enterprise-D. In 2370, this lab and the arboretum both attracted personnel who had succumbed to Barclay's Protomorphosis Syndrome. (TNG: "Genesis" ) The existence of such a facility was canonized in the episode "The Perfect Mate" , but it was not mentioned by name in that episode. To date, the facility has never been shown. It may be the same facility mentioned in the episode "Yesterday's Enterprise" , where it was referred to as "Cetacean Ops".
