EASTERN BROOK TROUT. 



Our efforts with this beautiful and gamy fish are being richly- 

 rewarded, as it can now be considered permanently established in all 

 suitable waters where it has been planted, but especially in the small 

 lakes and meadow streams of the higher Sierras-. Eastern brook trout 

 have shown some adaptability to the large reservoirs in lower altitudes, 

 but to the Coast Range streams they are not as well adapted. We 

 have made some large plants of fine, healthy fish, but no increase has 

 been apparent. We believe this is due to the fact that these streams 

 are subject to sudden rises in the winter, which interfere with their 

 spawning season, the eggs or alevins being easily destroyed by the tor- 

 rential floods to which the streams are subject. We therefore would not 

 recommend their planting to any extent in the Coast Range streams, 

 except in reservoirs or such waters as are not subject to much change. 

 We shall, however, continue to stock all the small streams, and those 

 larger ones in the higher elevations where neither the Rainbow nor the 

 Cut-throat trout will remain. 



From our stock of breeders at Sisson that are a result of eggs secured 

 in exchange for Rainbow eggs with the Federal Bureau of Fisheries 

 station in Colorado, we have now an ample supply in our rearing ponds. 

 During the season of 1905 we liberated upwards of 600,000. The season 

 just closed we planted about 750,000 fry ranging from 24 to 4 inches in 

 length, and expect in 1907 to reach 1,000,000, which will be not only 

 ample to maintain the supply in streams and lakes already stocked, 

 but sufficient to stock new waters. 



These fish possess a decided advantage over our native trout in respect 

 to their spawning season, which occurs in the latter part of October and 

 November, a period when they can breed in the high elevations unmo- 

 lested. They also mature a year earlier than any of our native fishes. 



During the past two years we have stocked barren waters in the 

 eastern end of Tulare and Fresno counties, in the Giant Forest region, 

 Paradise Valley, and the Sequoia and General Grant National Parks, 

 and also furnished a new supply for the Yosemite region. For stocking 

 the National Parks in Tulare County substantial assistance was received 

 from the Department of the Interior, which set aside a sum of money 

 to bear the expense of transporting the fish long distances by team and 

 pack animals. New lakes in the Glen Alpine region, tributary to the 

 Tahoe basin, have been stocked with these fish, and substantial plants 

 have been made in lakes and streams at an elevation of from 8,000 to
