tie POWAN=Or LOCH. LOMOND 
(Coregonus clupeordes) 
Powawn are found in large numbers in Loch Lomond, and are said to 
attain to the weight of 2 Ibs. None of the specimens I have seen, 
however, weighed more than 1 lb. The powan is a beautiful fish. 
The head and back are light olive brown, and the fins light slate 
colour. The scales above the lateral line are well defined in eight 
rows, while below the lateral line to the anal fin there are also eight 
well-defined rows. The scales are silvery like those of a grayling, 
and the belly is white and covered with scales. The eyes are very 
large, and the upper edge is on a level with the head. The centre of 
the eye is black and is surrounded by silver, while the side of the head 
is like burnished silver intermingled with irradiating pink colour. The 
number of rays on the fins are as follows: the dorsal eleven; the 
second none; the pectoral seventeen ; the anal ten; the ventral ten ; 
the caudal twenty. The specimen figured was 12 inches long, and 
weighed three-quarters of a pound. Like all the others I examined, 
its stomach was full of daphnie. This is their principal food, although 
I have occasionally found them to feed on the larve of the blood- 
worm. The scales are like those of the salmon, except that the rings 
continue right round. The rings are well defined, showing that the 
feeding has been rich. From the number of rings I make the age 
of the specimen shown to be four years. 
Powan are rather coarse for the table. Large numbers are 
netted in Loch Lomond and sent to the markets, and occasionally 
they are caught by the angler. Loch Lomond is of vast size, 24 miles
