Salmonidas of Norway, 8i 



Nothing was recorded of their proceedings for an 

 entire season. 



Thus of 48 fish marked and recaptured, it is proved 

 that 18 spawned twice in consecutive breeding seasons, 

 and that 30 fish spawned one season, that nothing was 

 seen of them during the next season, but that during 

 the second season after marking they were recaptured 

 as kelts or fish about to spawn. 



These 30 fish may have spawned or may not have 

 spawned in the season during which nothing is recorded 

 of them ; but, as Mr. Walter E. Archer points out, there is 

 negative evidence in favour of their having missed a season. 



Fish remaining in the sea from twelve to eighteen 

 months at a time would be expected to gain more in 

 weight per annum than those which spawn annually, 

 and we have here the fact that these 30 fish which, so 

 to say, were lost sight of for an entire season, gained 

 half as much again in weight per annum as compared 

 with the 18 fish which spawned annually for two years. 



Again, of the marked fish, on account of the risks 

 run by fish and labels, it would have appeared probable 

 that more would have been recovered during the first 

 season after marking than in later years, but the opposite 

 has been the case — 18 fish having been recaught during 

 the first season after marking, whereas 30 fish were re- 

 captured during the second year after marking.
