different lines and are different from those built in states like 

 Kansas, Missouri and Illinois, where fish that spawn adhesive 

 eggs are to be hatched and reared. For the successful propa- 

 gation of fish that produce adhesive eggs it is necessary to fur- 

 nish a water supply great enough for the fish to live m and for 

 them to spawn in and care for their own eggs, nests and young. 

 Therefore, the number of fish producing adhesive eggs that can 

 be hatched and raised to any given size, in any given body of 

 water, depends largely upon the "household room furnished 

 by that particular body of water, and its successful operation 

 depends largely upon its natural food supply. 



THE KANSAS FISH HATCHERY. 



The fish that will be propagated at the Kansas State Fish 

 Hatchery belong to the group which produce adhesive or 

 sticky eggs. The number of spawners or breeding fish that 

 should be placed in a given body of water, say an acre, de- 

 pends upon a number of things, and especially upon the kind 

 of fish and the food supply of the water. First, it is necessary 

 for that acre of water to have a supply of food that will sup- 

 port the breeding stock. Second, that acre of water must 

 contain minute animal and vegetable life sufficient to supply 

 food for the thousands and hundreds of thousands of young 

 fish that hatch and come into existence soon after the spawn- 

 ing or egg-laying season is over. If the food supply of animal

and plant life is not very great, it is easy to understand that a 

 great number of these young fish will perish, a thing that 

 actually does happen in all ponds that are not well supplied 

 with food. The above suggestion will explain in a way what 

 will be more fully explained later, namely, that it is necessar> 

 to have a large fish hatchery, or at least a large acreage of
