CATCHING YOUR FISH AND COOKING IT WITHOUT MOVING FROM YOUR TRACKS 
The Yellowstone Trout {Salmo lewisi) is very abundant in Yellowstone Lake, Yellowstone National 
Park. The “boiling pot” is one of the numerous hot-water holes to be found in this region. The sur¬ 
rounding water is cold. 
its peculiar forms of these, all well known 
to ichthyologists, who have described and 
named them by the score. 
Some of our smallest fishes have been 
found useful in combating malaria and 
annoyance caused by mosquitoes, and are 
even being shipped by the United States 
Bureau of Fisheries to mosquito-plagued 
foreign countries. There is now in prog¬ 
ress much active investigation regarding 
the value of several species of fishes for 
the control of the mosquito. 
UNITED STATES HAS FIVE TIMES AS MANY 
KINDS OF FISHES AS EUROPE 
The richness of fish life in our fresh 
waters is amazing. The United States 
has a smaller area than Europe, yet it has 
nearly five times as many kinds of fresh¬ 
water fishes. We have about 585 species 
of these, while Europe has but 126 
species. 
We find that a single State may have 
considerably more than 100, the number 
known to Illinois being 150, while New 
York is credited with 141. It could doubt¬ 
less be shown that our fresh-water fish¬ 
ery resources are greater than those of 
any other country. 
Many of the fishes commonly taken for 
food or in sport fishing, and naturally of 
wide distribution, have, as a result of fish- 
cultural operations, been established in 
sections of the country far removed from 
their original habitat. 
A fish belonging to the Mississippi 
system or to the Atlantic slope often 
takes full possession of a new water¬ 
shed, as the result of mere trans-planta¬ 
tion of limited numbers. 
Although the numbers of fishes caught 
by anglers do not figure in statistics of 
the catch made for market, they are not 
without high economic and other values. 
Most of the Northern States are visited in 
summer by tourists interested primarily 
in good angling waters. 
Lakes far and wide have become 
summer resorts for people who find much 
of their recreation in fishing. Railways 
and summer resorts widely advertise the 
resources of their waters. Summer 
visitors, moving actually by hundreds of 
thousands, carry into these States millions
