 The object in view was to stock the rivers with 

 fish by the iatroduction of ova and young fry of 

 the best lands, and those of rapid growth — salmon, 

 trout, ombre chevalier, and fera, heuch, alose, and 

 sturgeon, the sterlet, and silure. The operations 

 on such species of fish as spawned in winter suc- 

 ceeded at once, whilst great difficulties attended 

 the impregnation and transport of the ova of other 

 kinds that spawned in the spring and summer. 



The ova have been principally collected in Swit- 

 zerland and Germany, and procured at various 

 seasons with great care and by competent men 

 employed for the purpose. On their arrival at 

 Huningue they are examined, and the quantity 

 ascertained by means of small stamped measures, 

 according to the kinds of fish and the size of the 

 ova, the spoiled ova being separated from the 

 soimd, and the whole is then carefully recorded; 

 the sound ova being carefully deposited for incu- 

 bation in separate compartments, and such as may 

 become addled are daily abstracted from the boxes; 

 and after two or three weeks those that remain in 

 a healthy condition are selected, packed up in wet 

 moss, and. inclosed in wood cases, and are for- 

 warded to various districts by the Government free 

 of any expense. The ova are given away for re- 

 stocking the waters, but the parties who receive 

 packets of ova are required to give detailed 

 accounts of the success of their previous operations 

 before a second supply be granted to them, the 

 demand for ova having always been greater than 

 the means of supplying it.
