The Salmon 



we did not know the change that had taken place was caused by their 

 having spawned. They are now spotted, and have maggots in their 



gills. These kelt grilse keep on re- 

 turning until December, and spawn 

 the same season (Fig. 39). 



I will now treat of what becomes 

 of the small spring fish kelts (Fig. 

 40) — those from December to the 

 middle of June. A smaller number 

 of this second run die after spawning 

 than of the kelt grilse. These kelts 

 return during the autumn, winter, 

 and spring, and most of them dis- 

 appear by the end of April. Like 

 the grilse kelt, they begin to return 

 again about the middle of June ; and 

 many of them are of the same size 

 as the grilse kelts — about 5 or 

 6 lbs. They increase in weight as 

 the season advances, and by Sep- 

 tember some are caught up to 

 12 and 14 lbs., according to the 

 weight of the kelt that went down. 

 Strange to relate, almost all the kelts 

 that have been marked on the Tay 

 and recaptured have been females. 

 Particulars of some of these kelts 

 that were marked and afterwards 

 nets are given
