SCANDINAVIAN FISHES. 
In his ‘Travels in WestergotlancV (1746, p. 259) 
Linnaeus gives a description of some perch-fishing in 
Lake Yngen in Wermland in which the tackle consisted 
of a circular net two yards in diameter. “The Perch 
always keeps close to the crags or rocks in the lake. 
Thither the fisherman rows and drops the net to the 
bottom, whereupon the Perch, which are always fond of 
rings and circles, begin to sport in crowds above it. 
When the net is drawn up, the Perch becomes frigh- 
tened, darts towards the bottom and is thus taken in 
the net, often in considerable numbers.” 
The Perch is also often caught by nearly all sorts 
of fishing-tackle set near its haunts for other fish. Thus 
large Perch are often taken by trolling, on a hook drawn 
along the surface of the water ( dragkrok ) and on a line 
fastened to a pole which is fixed in the bank (st any kr ok). 
In the autumn too it is often struck with a gig. 
Besides the culinary value of the Perch, its usefulness 
in other ways deserves mention. It is a fact well known 
from the earliest times that, by boiling, an excellent 
glue may lie extracted from its skin. In several places 
in Sweden the scales are used in making all sorts of 
personal ornaments, being arranged in the shape of 
leaves and flowers for bracelets, necklaces, earrings and 
ornaments for the hair. As the Perch is of such com- 
mon occurrence, it is a comparatively cheap fish. In 
spring the average price of a middle-sized, live Perch 
in Stockholm is from 2 7 4 d. to 37 4 d. ; at midsummer 
it is scarcer and the price higher, in autumn the price 
sometimes rises as high as 5 1| 4 d. and during winter 
it is sometimes as much as 6 3 / 4 d. (Ekstrom, Smitt.) 
Genus STIZOSTEDIUM A 
Body oblong. Scales small with the margin sharply dentated. Preoperculum and shoulder-girdle serrated ( inferior 
margin of the preorbital bones even). Cheeks scaly , scattered scales on the occiput. Teeth set in one row ( some- 
times irregularly in 2 or 3) on the inter maxillaries, the lower jaw and the palatines , with scattered canine teeth 
largest on the anterior part of these bones. A transverse row of car di form teeth ( often disappearing in older spe- 
cimens) on the vomer. Tongue without teeth. From 3 to 7 pyloric appendages. Pseudobranchice complete. Bran- 
chial membranes separate with 7 rags on each. From 13 to 16 rags in the first dorsal Jim. In the anal fin 2 
spinous rags; the base shorter than that of the second dorsal fin. In the caudal fin 15 branched rags.
