According to a statute from 1324, what does Queen Elizabeth II technically still own?

Explanation

Queen Elizabeth II is the second-longest reigning monarch in the world. According to a statute from 1324, technically, the Queen still owns the sturgeons, whales and dolphins in the waters around the UK. To this day, when these animals are captured within three miles of UK shores, or washed ashore either dead or alive, they may be claimed on behalf of the Crown.
