Burbot to come Back?

Natural England have suggested that they are to attempt to reintroduce a predatory cod species, the Burbot, to the UK rivers (https://www.theguardian.com/environment/2020/mar/06/return-of-the-burbot-great-lost-fish-to-be-reintroduced-to-uk). The species only disappeared about 50 years ago and the thinking is that the newly-cleaned waters will facilitate the return of this fish. Of course, there may be problems with the fish's  diet as predatory species might well endanger other inhabitants of these ecosystems.
