REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



39 



The followiug table shows the number and kinds of fish on hand at 

 the beginning of the year: 



These fish were held at the station and cared for in the rearing-ponds 

 until late in the fall. The distribution commenced in December and 

 lasted until January 22, during which time 73,930 yearling rainbow 

 trout, 3,440 Von Eehr trout, 53,019 rock bass, 3,761 black bass, 3,970 

 tench, 340 carp, 1,905 catfish, and 7,857 goldfish were distributed. The 

 net output of the basses and trout was very discouraging in view of 

 the fact that these fish were carefully assorted each month and the 

 different sizes kept separate. The loss of the bass was undoubtedly 

 due to cannibalism, though enormous quantities of Coriza were collected 

 as food for them. This food is very acceptable to the rock bass, but 

 the black bass have been observed to eat each other when the bottom 

 of the pond was covered with young Coriza. In view of these losses 

 it is strongly recommended that the distribution hereafter be made 

 duriug the mouths of September and October, as it is believed that a 

 much larger percentage of the fish can be saved by so doing. In addi- 

 tion to this better results can be obtained by planting fish in the early 

 fall, when the water is full of natural food. 



Rainbow trout. — The brood stock consisted of 362 2-year-old and 503 

 5-year-old fish. The spawning of this speties extended from December 

 8 to February 24, during which time 782,000 eggs were obtained. Of 

 these, 448,000 were shipped to State Fish Commissions and to the other
