WISCONSIN AQUATIC NURSERIES, 
IMPORTANCE OF AQUATIC VEGETATION 
FOR GAME FISH 
Many of the same plants which are important 
food plants for waterfowl are also important food 
and cover plants for game fish. Therefore, one will 
improve both hunting and fishing by establishing a 
growth of aquatic vegetation in that lake, pond or 
stream. 
Plant life takes a very important part in the puri¬ 
fication of waters by taking up the poisonous carbon 
dioxide gases given off by soil decomposition which 
asphyxiate fish life, and sending forth in its place 
the oxygen into the waters which is so essential to 
fish life. These plants also support countless num¬ 
bers of minute animal life upon which the young 
fry are dependent for their feed. They also provide 
excellent shelter and hiding places for the younger 
fish to hide and escape the larger ones which are of 
a cannibalistic nature, feeding upon their smaller kin. 
Food, protection and better living conditions for 
the small fish mean that many more grow to matur¬ 
ity, thus more fish, larger fish, healthier fish and 
better fishing. 
Aquatic vegetation also assists in the clarification 
of the waters. It binds the soils and prevents turbid 
water, also collects the floating particles of sediment. 
It shades the under waters keeping them cool which 
is very helpful and healthful to the fish life; also 
provides better spawning beds. 
In order that there be a plentiful supply of fish 
in any waters it is first necessary to protect the 
small fry. They cannot feed upon the larger insect 
life or upon one another as the larger fish do and 
as a result in waters barren of aquatic vegetation 
millions of the small fish* perish unbeknown to you.
