Large quantities of eels are caught in the Frisian lakes.
The most valuable catches of food fish in 1904 were those of bluefish ($556,527), squeteague ($212,623), flounders ($67,159), eels ($53,832), cod ($52,710), scup ($48,068) and shad ($36,826).
Salmon, lampreys and eels are caught in some of the larger rivers; trout abound in the streams of the northern provinces; but many fresh-water fish common elsewhere in Europe, including pike, perch, tench and chub, are not found.
Owing to the long line of coast and the numerous lakes, fishing forms an important industry, and large quantities of herrings, eels and lampreys are sent from Pomerania to other parts of Germany.
The kinds of greatest economic value are sturgeon, shad, salmon, lampreys, eels, pike and whiting.
