The first consigumeiit of shad eggs was received from Bryan Point 

 on April 14, and shipments continued uninterruptedly from that time 

 until the 29th of May, 31,877,000 of the 39,719,000 shipped being received 

 in good condition. A consignment of 640,000 was also received from 

 the Delaware River on May 22. 



During the season 25,346,000 fry were hatched and distributed, and 

 2,070,000 eggs were shipped to Nashville for exposition purposes; the 

 balance were lost during incubation. The eggs were transferred from 

 Bryan Point by means of the Fish Commission launch instead of by 

 passenger boat, as in past years. 



At the close of the year the superintendent was detailed for duty in 

 connection with the construction of the station at Erwin, Tenn. 



Aquarium at Central Station (L. G. Harrox, in charge). 



In October arrangements were made to restock the aquarium with 

 salt-water fishes from Chesapeake Bay, but owing to the prevalence 

 of heavy gales it was impossible to obtain good collections. Fresh- 

 water fishes were collected from time to time in the Potomac River, 

 and consignments of trout and salmon were received from the New 

 England stations. 



Comparatively little difficulty was experienced during the year with 

 fungus or disease of any kind. 



During March and April 19 yellow perch spawned in the aquarium, 

 but eflbrts to hatch their eggs were unsuccessful; this was attributed 

 to the presence of alum in the filtered water. Two rainbow trout 

 spawned early in March and another on May 12; none of the eggs 

 hatched, though effort s were made to save them. The goldfish spawned 

 in April and May and the eggs were placed in a separate aquarium in 

 the greenhouse, where they^were hatched. 



The fresh-water fishes, with the exception of the lake trout, were held 

 without loss until May 6, when a part of the steelhead trout and quinuat 

 salmon were transferred to Nashville. The balance v/ere retained with 

 comparatively light losses until June 18, when they were liberated in a 

 small spring fed pond about 10 miles from Washington. Several adult 

 rainbow trout, weighing from li to 2 pounds, a number of 2-year-olds, 

 and a few steelheads were retained in the aquarium for experimental 

 purposes, and lived until July 4, when they died at a temperature, 

 of S20.
