Rekefisket som naturhistorie og samfundssak
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1938)1. Trawl fishing for deep sea prawns commenced in Norway in the autumn of 1898 after Hjort had proved in 1897 the existence of great quantities of P. borealis in the fjords of East Norway.

Scale Character and Growth Rate - A study on small fat herring from North Norway
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1959)From the mean values it can be seen that herring of the "Southern-type" in both years have the same growth rate as those of the "Northern-type". The conclusion must be, therefore, that the correlation, "N-type" - slow ... -
