REPORT OF COMMISSIONER OF FISH AND FISHERIES. 5] 
did the previous year, and this field will doubtless prove even more 
productive in future. 
On April 24 the superintendent was relieved from duty, and Mr. 
J. B. Rogers, fish-culturist, was placed in charge until the close of the 
season. The egg productions by areas were as follows: From the 
Chowan River, 1,905,000; Roanoke River, 10,872,000; Albemarle 
Sound, 62,623,000, a total of 75,400,000. By apparatus the production 
may be recapitulated as follows: Trap nets, 2,783,000; gill nets, 
3,766,000; seines, 68,851,000. 
The number of fry produced was 51,280,000, or 68 per cent of the 
number of eggs received. <A study of completed tables of production 
shows an abnormal loss on 13 lots of eggs between April 8 and May 1. 
Two of these lots suffered from an electric storm, namely, those on 
April 30 and May 1. The other 11 lots referred to were selected from 
the records as representing the largest individual shrinkage, and are 
as follows:

While on the 8,285,000 eggs of April 30 and May 1, killed by an 
electrical storm, there was a loss of 50 per cent, on the above 11 lots 
there was a loss of 60 per cent. On all other eggs of the season there 
was a loss of only 11 per cent, as shown below:

Of the eggs collected in 1900, 63 per cent were hatched. 
Air bubbles again formed in the water supply to the hatchery on 
sudden rises of temperature, due probably to rapid expansion of air 
in the water-pipes between the suction well and hatching-jars; this 
suggests the desirability of covering the exposed parts of the pipe 
system with asbestus or some other nonconductor. 
The fry were distributed by messengers in North Carolina waters, 
principally in Albemarle Sound and its tributaries.
