CHANGES IN WEIGHT AND SIZE OF TAGGED COD. 
In the comparatively short time elapsing between the release and the 
capture of the tagged fish, but little opportunity has been afforded for 
obtaining data of much value on the rate of growth of the species. 
The records show a great irregularity in the changes in weight, some 
fish increasing inordinately, some but iittle, and some not at all. 
The tagged fish recaptured were at liberty from 2 days to 15 months, 
the average time being 4+ or5 months. The number at large 6 months 
or more was 11. Only 3 fish were taken in the fall or winter succeed- 
ing release; one of these (No. 458), liberated January 31, 1898, was 
caught November 15, 1898; another (No. 880), liberated December 
30, 1898, was caught November 1, 1899, and the third (No. A 870), 
released January 18, 1901, was caught in December, 1901. Only 1 
fish was taken more than a year after release; this (No. C 95) was 
released February 3, 1899, and caught May 9, 1900. 
In the case of the weight the basis for comparison is diminished in 
value by the poor condition of the fish at the time of release (owing 
to the loss of weight incident to captivity and the spawning condition) 
and by the questionable accuracy of the figures as submitted by the
