REPOET OF COMMISSIONER OF FISH AND FISHERIES. LXXIX 



chevalier. Through the courtesy of the presideut of the Deutsche Fisch- 

 erei-Verein a number of the eggs were received in January, 1881. and 

 sent to the fish commissioners of New Hampshire, at Plymouth, for 

 development. They proved hardy and grew satisfactorily, and on De- 

 cember 3 of the present year about 600 eggs were taken by Commis- 

 sioner Bodge. These will be transferred to another station, to be 

 hatched and reared ; and it is hoped that the species may in time be- 

 come weU known in this country. The fish is specially adapted to the 

 deep waters of cold lakes, being very abundant in the Geneva and 

 other lakes of Switzerland.

The McCloud Eiver Station. — The season for taking trout eggs opened 

 on January 3 and continued until the 5th of April, when it was found 

 that from over 33 spawning females 388^000 eggs had been taken. Mr. 

 Loren W. Green was more particularly in charge of this station, although 

 Mr. Stone retained the general supervision, and the latter states that 

 Mr. Green is entitled to great credit for the endurance and persever- 

 ance exhibited in his work. 



Each year a number of parent ferout are taken from the river for the 

 purpose of replenishing the trout ponds and to make up for the yearly 

 losses sustained. This season, for the first time, several thousand 

 young trout were reserved in the liatching troughs, and, later, 12,000 

 were placed in a pond by themselves to be reared for breeders. This 

 necessitated some new ponds, which were built during the year. In 

 order to help maintain the supply 20,000 fry were turned loose in the 

 river. Of eggs there were lost during the various operations but 24,000, 

 and the remainder, 332,000, were forwarded to Washington and various 

 State . hatcheries. For further details of the work reference maybe 

 made to the report of Mr. Stone in the appendix, where will be found 

 some interesting remarks upon the abundance of panthers, wild-cats, 

 lynxes, raccoons, minks, otters, and other frequenters of the region. 



The Northville Station. — It has been found that since the rainbow 

 trout were brought from California to this station their habits have so 

 far changed that they have become winter spawners. Mr. Clark be- 

 lieves that in a few years they will spawn simultaneously with the brook 

 trout. In January and February he took 125,000 eggs, but only suc- 

 ceeded in fertilizing one-fourth of them. He shipped 12,000 eggs to Mr. 

 Mather for Germany, 3,000 for France, and 3,000 for England. He 

 hatched 10,000 fry, which were planted in Indiana, Michigan, and Ohio. 

 There was also received a case of 4,000 rainbow-trout eggs on March 18 

 from the McCloud Eiver station. These arrived in prime condition, 

 and the fry which were hatched from them were added to the breeding 

 stock. Two new trout ponds were completed in June of the present 

 year.
