WORK OF THE COLLECTOR. 



The Collector has brought in during the year over lOO different 

 species of local fresh- and salt-water fishes and marine inverte- 

 brates, amounting to many thousands of specimens. Some of 

 these were exchanged with other aquariums and great quantities 

 of the smaller forms were used as food for the larger species on 

 exhibition. 



THE FISH HATCHERY. 



The fish hatchery, which was added to the equipment of the 

 Aquarium three years ago, was installed chiefly as an exhibit of 

 the modern methods of fish-culture. It has proved not only in- 

 teresting and instructive to visitors, but profitable to the Aquar- 

 ium. 



The eggs of fishes used in operating it have been supplied from 

 the beginning by Government fish-cultural stations in different 

 parts of the country, and the young fry turned out have been 

 liberated in State waters through the cooperation of the New 

 York Fish Commission. 



A small proportion of each lot of young fishes has been reared 

 in the Aquarium for exhibition, and the tanks now contain food 

 and game fishes, varying in age from one to three years, which 

 were hatched in the building from artificially fertilized eggs.
