EGG COLLECTIONS 
A large output of fish is the result, of course, of a large take of 
eggs. However, there is considerable discrepancy between the num- 
ber of eggs handled and the number of fish obtained from them, as 
inevitably losses will occur during hatching and rearing. The 
quantity of eggs collected from hatchery brood fish (principally 
trout) is regular and dependable, but if wild fish must be depended 
on for the supply of eggs, the number that will be obtained will be 
uncertain. Weather conditions influence the extent of the fishing, 
and unlooked-for events may affect the abundance of fish or their 
readiness to spawn. As the following tabulation will show, declines 
in the take of certain species are more than offset by gains in other 
groups, but it is more desirable that the output of shad, for instance, 
be increased 1,000,000 than that a decline in the abundance of shad 
be offset by an increase of 100,000,000 in some other species, such as 
the cod.
