30. Acipenser sturio Z. Sturgeon. 



Not uncommon off the coast, also at the mouth of the Tees, 

 in the Humber, and in the tidal reaches of its tributary 

 rivers, which it ascends about June, its upward progress 

 being, however, barred by the first dam or weir. Formerly 

 before the erection of these obstructions it has been 

 known to ascend the Ouse as far as Boroughbridge, and 

 the Wharfe to Boston Spa and Arthington. Near Bridling- 

 ton, it has been several times caught in the stake-nets.
