518 THE COAL-FISH. 



statement, that it spawns at tlie same time as the Common 

 Whiting, namely, in March and April ; as also that of 

 Couch, quoted by Yarrell. that the Pollack sheds its roe 

 in the winter. Its flesh seems to be the least valued of 

 all the Gadi, that is in Sweden ; but in Denmark, as well 

 as in France and England, it seems to be rather liked. 



Nilsson notices another kind of Pollack, called by him 

 the Gadiis EsvKD-kti, Nilss., that is common, he says, in 

 the Christiania Pjord, and there goes by the name of 

 Oien-paal. This small iish, whose length seldom exceeds 

 six to eight inches, and which was first recognized as a 

 species by Professor Esmark, might be easily mistaken 

 for the young of the Pollack, but for the presence of the 

 small beard, the shorter head, and the larger eyes and 

 scales. Nothing is known respecting its habits. 



The Coal-Pish* [Grd-sej,^w.; Sej, Graa-s^y, Danish ; 

 Gaelics carbonar'ms [old fish?], G. virens [young fish?], 

 Linn.), whose proper home would seem to be the Arctic 

 seas, is common in the Bohus Skargard and Cattegat, and 

 also all along the Norwegian coast up the North Cape ; 

 but it is said to be somewhat scarce in the Sound ; and 

 thougli Kroyer admits that some few enter the Baltic, 

 he altogether gainsays Yarrell's statement as to their 

 being plentiful there. It attains to a large size, three feet 

 and upwards. Kr5yer speaks of having seen an indi- 

 vidual three feet eight inches in length. The adult fish 

 hold most to the deeps, where the bottom is rocky ; but 

 the young resort greatly to bays and inlets, the water 

 there being comparatively shallow. In their habits, also, 

 the old and the young differ widely; the former assimilating 

 more to the Cod, whilst those of the latter are more akin 

 to the Mackerel ; for in the summer they seldom keej) to 

 the bottom, but for the most part in mid-water, following 



* The Green Cud of Pennant and Yan-ell is not recognized by Northern 

 naturalists, they considering it as no other than the young of the Coal-Fish.
