 why this is allowed is because the burbolts are so very 

 destructive to the eggs of all other fish in the lake, 

 especially perch. Burbolt stands frost well, and after 

 having been frozen quite stiff will revive. They eat an 

 enormous quantity of fry ; they swim after the fashion 

 of eels. They leave the lake for the rivers at night. 

 About ten o'clock they ascend the rivers, and retm-n

 the fishermen. No explanation of the fact is known. 

 Night-lines are laid for burbolts in the lake ; trammel- 

 nets are also used for them, especially at the time when 

 they are feeding on young perch. The flesh is said 

 to be good, especially the liver when fried, but it is 

 indigestible.
