in to shore. Such varying conditions are of great importance in studying the progress 
of the fishery, and may considerably affect the yield. In such years, when the herring 
spawn deep, there will probably be a great discrepancy between the prospects as to size 
of the stock and the yield of the fishery. An investigation of these conditions is therefore 
of great importance, and it is highly desirable that such should be regularly carried out. 
Similar conditions also prevail in the skrei fishery. It may perhaps be of interest 
in this connection to consider an example illustrative of the Lofoten industry; I will 
therefore briefly mention the observations made during the last season (1913), with the 
assistance, at first of Mr. Einar Lua and Mr. Oscar Sun», later also of Capt. RONNESTAD, 
as to the temperature and salinity in Vestfjorden. Figs. 127—130 illustrate some of 
Fig. 127. Temperature in Vestfjorden (Lofothavet) at 50 m. depth, 
during the skrei fishing season in 1913. The innermost stations correspond to the Tranö section 
(Fig. 128) those in East Lofoten waters to the Gröttö section (Fig. 129), and the West Lofoten 
stations to Fig. 130. 
the results here obtained as to the distribution of temperature in this water in March- 
April 1913, Fig. 127 showing the various temperatures at 50 metres depth. It will be 
seen that the temperature outside Vestfjorden was at this depth over 5° C., decreasing 
inwards to 2°.5 (at Tranö). This must be presumed to be due to the presence of 
colder water from the fiords, a view which I have already previously advanced, and is 
also evident from the temperature sections shown in Figs. 128—130. 
The three figures show the conditions of temperature as discernible in cross sections 
of the fiord, one far up, from Kanstadfjord to Tranö, (Fig. 128) one from Henningsvær 
to Gröttö, (Fig. 129) and a third from Moskenes in West Lofoten to Helligvær, (Fig. 130). 
All the sections exhibit a wedge of colder water on the left of the figures, 1. e. the 
Lofoten side, indicating that a part of the banks on which the spawning takes place
