54 Interrelationships of Fishes and Lake Habitats 



their population from winterkill can be managed by stocking large num- 

 bers of bass fry, which are often obtainable in quantity. The rapid de- 

 velopment of a fishable population after a partial winterkill often rests 

 with the ability or willingness of the lake or pond owner, whether an 

 individual, a club, or a State Department of Conservation, to quickly 

 appraise the damage and execute a plan to rectify it before the fish 

 surviving the winterkill have produced young. However, once a lake 

 becomes overloaded with a superabundant population of sunfish, crappies, 

 bullheads, carp or buffalo fishes, much more radical measures are needed 

 to restore fishing.

SUMMERKILL 



Summerkill, as a major catastrophe, is less common than winterkill. On 

 the other hand, there is some evidence that more fish die naturally in the 

 summer period (and are never observed by man) than at any other 

 time of year. There are several records of the disappearance of relatively
