REPORT OF STATE HOARD OF FISH COMMISSIONERS. 



mon — and any work in the water is disagreeable to say the least. Early in the summer 

 of 1905, after consultation with your Chief Deputy, Charles A. Vogelsang, as to ways 

 and means, and being assured by him that, owing to the large amount collected in fines 

 for violations of the fish laws, which he thought would enable us to meet the expense 

 of this new building without wailing for aspecialappropriation, I recommended to your 

 Honorable Board the construction of a new and permanent hatchery of a slightly 

 greater capacity than the old building As soon as our pond work would allow, we 

 began tlie erection of a building 40 by 120 feet, one third pitch roof, 10 foot sides. It was 

 built by, our regularcrew, and when completed was the most substantial building on the 

 grounds. It was made plain and durable. The troughs were set on long sills running 

 lengthwise with the building, and no joists < r flooring used. A gangway or walk was 

 built between each of the sections, thus making a good dry walk or aisle between the sec- 

 tions of troughs. The outlets for the escape of water from the troughs are built so as to keep 

 the volume of water in view until it falls into the waterway that carries it away from 

 the building. This enables the assistants cr any one passing through the main aisle of

the building to see at a glance if the water is running freely through all the troughs. 

 This is quite an improvement over the old system. The building contains 92 troughs, 

 and with those in the other two hatcheries make a total of 230 troughs, which have a 

 capacity of over 1,300 baskets. 



Early in the fall of 1905 the great number of salmon in the Sacramento River gave 

 promise of a larger number of eggs than were taken the previous season, showing that 

 the salmon in the Sacramento River were still on the increase. This proved to be true. 

 We received from the Bureau of Fisheries Stations during the fall and winter of 

 1905-06, 96,550,000 Quinnat salmon eggs, which were successfully hatched with only a 

 small loss, and the fry liberated in the Sacramento River. This we were enabled to do 

 by having the new hatchery completed and the nursery system for rearing the fry 

 improved. The fry were ieleased at a time when they were in the best condition for 

 starting on their journey to the ocean ; that is, when their sac of pabulum was absorbed 

 enough to allow them to swim freely. This plan of liberating the fry has proven most 

 successful. If they are fed or held too long at the hatching station, they do not move 

 down the stream as rapidly as they should, and consequently a larger percentage are
