3. The water bailiffs employed are 10 in number and one superintendent. 



4. Particulars as to prosecutions instituted are briefly as follow : — There were 



tour contraventions of the Salmon Fishery detected for 1912, implicating 

 5 men and 2 boys. The cases consisted of having unclean fish in 

 possession, kiiling and having salmon smolts in possession, taking 

 salmon during the annual close time, fishing with rod and line during 

 the close time for rod and line in the Forth District, and fishing for 

 trout with salmon roe. 



Obstructions to the Passage of Pish— 



2. Are the bye-laws observed in every case ? — No. Hecks are not kept at 



intakes and outlets of the mill lades. 



3. Fish passes built or in prospect :— The fish pass on the Allan at Airthrey 



Dam Dyke has lately been improved by the erection at the intake of a 

 sluice to regulate the flow of the water into the pass. The sluice this 

 year has been a great success. When the river came down in flood the 

 fish that failed to enter the pass were carried down into the pool below 

 the pass, and, finding an easy access into the pass, and an equally easy 

 ascent from the operation of the sluice, the fish ascended the pass in 

 large numbers, and for the first time for several years practically the 

 whole of the spawning fish were enabled by the improvements on the 

 pass to ascend to the upper reaches of the Allan. Large numbers of 

 fish have been seen on the spawning grounds, and it is anticipated that 

 the present season will be one of the best spawning seasons in this 

 district for many years.
