In continuation he expresses the opinion that the alert- 

 ness of the gravel-hatched fish is a factor worthy of consid- 

 eration when estimating the relative chances of survival of 

 these and hatcherj^-reared fry. 



One hundred cohoe salmon eggs were planted in coarse 

 clean gravel, within an hour after the parent fish were strip- 

 ped. Seventy-five fry hatched in healthy condition. 



The following plantings of sockeye eggs were made 

 during the past season at the Harrison Lake Hatchery by 

 means of the Harrison Planting box :

 eggs planted sultant fry. 

 No. 1 500 456 

 No. 2 500 420 

 No. 3 500 407 

 No. 4 500 200 

 No. 5 500 401 



The superintendent reports that there was a hole in the 

 screen of No. 4 and fry escaped which were not counted. 



Two plantings of green eggs in gravel were also made, 

 in one case with soft and in the other with hardened eggs» 

 with the following results : 



1,000 soft green eggs produced 350 fry 



1,000 water-hardened eggs produced 400 fry 



Altogether at this hatchery 300,000 sockeye eggs were 

 planted in gravel in the vicinity of the hatchery last fall, 

 including the experimental plantings mentioned above. The 

 superintendent reports that the results of these plantings 

 have been good. Careful watch was kept and large num- 

 bers of young sockeye resulting from the plantings were 

 seen. The plantings at Morris Creek amounting to 1,413,- 

 000 eyed eggs also turned out very well. This point was 

 inspected and great quantities of sockeye fry were later 

 observed in the creek. 



On January 29th, 1923, three plantings of eyed spring 

 salmon eggs were made in Oliver Creek near the Cowichan 

 Lake Hatchery — 500 in each planting, with the following 

 results : 



Planting No. 1 — 437 fry, 



2 — 465 " 



3 — 476 "
