REJ'OKT OF THE FISH AND GAME COMMISSION. 



AVith its five hatchery buildings and auxiliary battery, containing in 

 ail over 500 troughs, and its 52 breeding ponds, the Sisson Station 

 must be considered one of the largest hatcheries in the world. The 

 station now has a capacity of fifty million trout and salmon fry per 

 season. 



One new pond was rented from ]\[r. Riijii). during the Avinter of 

 1915-16. The lease on the large pond, known as Sisson Lake, expired in 

 the fall of 1915 and we were not able to have it renewed, so Mr. Eupp,

who owns one of the large ponds leased by the commission for salmon 

 culture, agreed to construct another pond and lease it to the commission 

 for the rearing of fish. The pond was completed early last winter and 

 stocked with salmon, where they are thriving. These fish will be dis- 

 tributed during the fall of 1916. We would respectfully recommend 

 that the commission take measures to purchase these leased ponds or 

 acquire more land near Sisson Hatchery to construct large ponds such 

 as these, of one acre or more in area, for the rearing of salmon fry. The 

 more experience we have in rearing salmon fry in ponds, the more we are 

 convinced that the best results in salmon culture are to be obtained 

 by rearing several million fry each season on the upper reaches of the 

 Sacramento River where the Avater is pure and cold and where the fry 

 can be liberated in Hit- fall out of the reach of the predatory fishes 

 that infest the Sacramento River after it enters the valley proper.
