42 FISH AND GAME. 



in captivity, it has been raised to a less extent than the brook 

 trout at our State hatcheries. An interesting hybrid with 

 beautiful markings was produced by crossing brown and brook 

 trout at the Sutton hatchery. 



Rainbow Trout. --The rainbow trout (Salmo irideus}, which 

 is a native of the mountain streams of the Pacific coast, has 

 been introduced with some slight success in Massachusetts. 

 This fish usually spawns in January, February or March, with 

 an average yield of about 900 eggs. It will live in water of a 

 higher temperature, and thrives in tidal streams. 



Chinook Salmon. The Chinook salmon (Oncorhynchus tsha- 

 wytscha) of the Pacific coast is the largest and finest of the 

 Pacific salmon. It has recently been introduced into Massa- 

 chusetts with the hope that this valuable fish may become 

 landlocked in our lakes. The practicability of rearing this fish 

 in a landlocked condition has already been fully demonstrated 

 in France. So far the most extensive stocking has been done 

 in Lake Quinsigamond at Worcester, where excellent results 

 have been obtained. 



White Perch. - - The white perch (Morone americana) is found 

 in both salt and fresh water, and is frequently taken in large 

 numbers in tidal creeks. Spawning takes place in May and 

 June. The eggs are very adhesive, and on this account arti- 

 ficial hatching is difficult. In captivity it is very susceptible to 

 attacks of fungus. No attempts have been made to rear the 

 young fish, but large quantities of small adults, seined in the 

 brackish water ponds, are annually shipped to the inland ponds, 

 where the species become landlocked. White perch is both a 

 gamey and an excellent pan fish, and for all classes of fishermen 

 is perhaps the most satisfactory pond fish. 



Yellow Perch. - - The yellow perch (Perca flavescens) , a native 

 of Massachusetts, is abundant in the southeastern part of the 

 State. It is found throughout the Great Lake region in the 

 United States, and east of the Alleghenies as far south as 

 Georgia. Spawning extends from December to April, and large 

 quantities of eggs furnished by the United States Bureau of 

 Fisheries are hatched each year at the Palmer hatchery for dis- 

 tribution. 



Pike Perch. - - The pike perch (Stizostedion vitreum), fre-
