If the museum confirmed that Stanley really was the endangered and protected British sturgeon, then the man who caught it would be guilty of a serious crime. It didn' t fit the normal pattern for our British sturgeon. You can look at the patterns on the scoots. But these are not in two. Yeah? Yes, that' s arguable evidence. The position of the whiskers on the snout. Oh, yeah. And most importantly the general shape of the snout was wrong. With the visual identification and inconclusive, Ollie and his team turned to DNA analysis. We got a big surprise. It was an American sturgeon. This meant that Stanley was the first American sturgeon ever recorded in British waters. So, Stanley could actually make everybody reevaluate the distribution of the North American sturgeon, totally. And that would have indications for the conservation movement ' cause people do want to reintroduce the sturgeon to the UK. |
