OBSERVATIONS ON FISHES. 



especially such as inhabit ponds, and other pieces of 

 water, from which there is no outlet. 



STURGEON.* 



STURGEONS, I believe, are seldom found but in 

 the larger rivers ; and then, according to Mr. Yar- 

 rell, " most frequently in the estuaries, or but a 

 short distance up." Every instance of their occur- 

 rence, therefore, under other circumstances is inter- 

 esting ; and I may mention the capture of one in 

 the Ouse, near Ely Bridge, on the 18th of June, 

 1816. This must be at least thirty-five miles from 

 the sea. The weight of this fish was Impounds 

 exactly. Its entire length was six feet seven inches : 

 from the extremity of the snout to the insertion of 

 the pectoral fin measured eighteen inches and a half: 

 from the end of the tail to the posterior part of the 

 dorsal fin, nineteen inches. These measurements 

 were taken by myself from the stuffed skin, which is 

 still preserved at Ely. The weight given above is 

 on the authority of the person into whose hands it 

 came when first taken. 



* Acipenser sturio, Linn.
