1904 DEPARTMENT OF FISHERIES. 15 



Coarse Fish in the Nipigon. 



The work of capturing and destroying coarse fish in the River Nipigon 

 was again carried on and 375 pike, 100 pickerel, and 380 suckers were 

 caught. 



Pollutions from Sawdust and Other Causes. 



A number of complaints have been received of the pollution of waters 

 from various causes, no fewer than twelve being with sawdust. Upon in- 

 vestigation, however, it was found that the practice had not been carried 

 on to any great extent, and was at once stopped when attention was directed 

 to the fact that it was illegal. One or two canning and sugar factories have 

 also been warned that some other disposition of their refuse must be made, 

 and they have acted accordingly. 



Black Bass in France. 



We gather from the English Fishing Gazette that . the experi- 

 ment of introducing the "American Black Bass" into French 

 waters has been such as to warrant further enterprise in the 

 same direction. In December of 1902, Mr. E. Roger received 

 from the Max. v.d. Borne fish-breeding establishment at Berneuchen, 

 n^ar Custrin, Germany, a consignment of 200 large-mouthed black 

 bass fry, which were put into a pond at his country home near 

 Paris. The fry were about 2\ inches in length when put out. In March 

 of 1903 he received and deposited in the same pond 22 fish which were about 

 seven inches in length. The bass thrived in their new home, and this year 

 ^n June it was discovered that they had spawned, "myriads" of fry beinar 

 observed. In July a fish of nine inches was caught, and is said to have 

 been "the first black bass ever served on a French breakfast table." 



Fishways. 



The Department has been advised by the Dominion that instructions for 

 the erection of fishways in several dams had been given. The subject being 

 cne coming under the head of regulations, applications made to this Depart- 

 ment have been transferred to Ottawa for whatever action might be con- 

 sidered proper or necessary. The prevailing opinion seems to be that if 

 fishways were erected in all the dams of the Province, thus affording a 

 roadway from one water to another, fish would soon be plentiful; but this 

 would ue far from desirable, as admitting into waters at present free there- 

 from fish of undesirable kinds. As has been recommended in former re- 

 ports, it would be much better to stock the waters where suitable with the 

 kinds desired and dispense with the fishways. The public should give the 

 matter very thoughtful consideration. 



The Georgian Bay Biological Station. 



This is one of three stations established in Canada (the others being 

 located in Quebec and British Columbia, respectively), in which to conduct 

 biological investigations as to the habits of the larger fishes, but more par- 

 ticularly those of food and game value, the artificial rearing of their young, 

 embryonic development, their natural food, and the microscopic life of the
