 SMALL-MOUTHED BLACK BASS WINTERING IN NEW YORK AQUARIUM 



Although the various species of fresh water fishes react differently to cold, it is known that many can 

 endure very low temperatures, even freezing. Certain species of the North like the Alaska blackfish 

 have extraordinary vitality, and when thawed out after lying frozen for many months will prove as 

 lively as ever. In winter at the New York Aquarium the water flowing through the tanks sometimes 

 reaches a rather low mark. When it is below forty degrees Fahr., some of the fishes become sluggish 

 and take little food. Young yellow perches remain on the bottom but the young black bass poise in water, 

 fifty or more compactly bunched, mostly heading one way. For the game qualities of black bass see Fishes,
