GREY GURNARD. 
109 
Malm found ripe eggs in a female Grey Gurnard at 
the middle of July; and the fishermen assured him 
that this fish "has no (visible) roe, either in spring or 
in autumn.” According to Sars the eggs float at the 
surface during their development". 
This fish is eaten in Sweden as well as in other 
countries, though it is not considered a delicacy, as 
the flesh is somewhat flabby and insipid. There 
is no special fishery for it, hoAvever. Its food con- 
sists chiefly of shellfish, crustaceans and small fishes. 
Malm found the stomach of a female crammed with 
Sprats.
