CHAPTER XIII. 



SEASON 1874-75 continued. 



FISH-CULTURE. 



THE experiments of this season I have described. I will now 

 touch on the actual fish-culture. My original stock were derived 

 from two sources only, for I never reared any of the Swiss trout 

 hatched in 1873-74 into breeders: the hill burns at Sauchie 

 supplied the fario, while the levenensis were obtained from Loch 

 Leven itself. 



1 had only a few Swiss trout and a very few Sauchie burn trout 

 at the beginning of the year 1874. Of the Swiss trout 120 were 

 placed in Loch Coulter in summer, and for seven years little was 

 heard of them ; the burn-trout, or rather the few that survived, 

 were placed in Craigend dam. 



The Loch Leven trout were all spawned at the loch (except 

 one spawner brought to Sauchie, whose eggs were used in Experi- 

 ment 8). The burn-trout were caught, and kept till ripe, and then 

 spawned, the kelts being placed in Craigend dam. The sea-trout 

 were guddled in the Touch burn. This burn is so small, it was 

 impossible to net it with any nets I had, but fortunately some old 

 man on the place liked sea-trout, and had made himself acquainted 

 with all their haunts. These were principally in the founds of a 

 stone wall, where the burn was banked to form a terrace in front 

 of Touch House, the understanding being, I was to return half 

 the sea-trout fry and half the Loch Leven fry. I returned half 

 the sea-trout fry, and placed the remainder in one of the reservoirs 

 on the Touch burn that supply the town of Stirling with water. 

 The sea-trout hybrids I retained. 



On the 21st I find the following note : " October 21. Sorted 

 56 spawning trout : 29 males, 27 females. Spawned 2 females :
