1 895 ^O 9 HYDR.-BIOL. STUDIES OF THE XORW. FISHERIES. JS 



placed at 120 to 140 mm. in July and ^August. The next group that 

 may be formed is a size which, during Summer, varies betAveen iSj and 

 160 mm., and which during the Autumn are called by the fishermen 

 s5-stregs sild Five Point Herrings), and which I conclude therefore are, 

 in the Summer, 2^/2 years old. During the Summer of 1894, the older 

 sizes were only met with in small numbers, and some were found be- 

 tween 200 and 280 mm. in length. I beHeve that all sizes above 185 to 

 160 mm. must be Herring which in tlie following Winter must belong, 

 either to the »250 mm. group or that of 300 ram.« 



In the trade, a difference is made, as is known, between Kjobmands- 

 sild' (Tradesman s Herrings), Middelssild Average Herrings), 3 Stor 

 Kristiania Sild< (Large Christiania Herrings), -Liden Kristianiasild« 

 ^Small Christiania Herrings) and »Fem stregs sildî (Five Point Herrings;. 

 In order to find out if these assortments, which Sars, in his Report for 

 the year 1873, presumes correspond to annual classes, I measured the 

 Herrings at several salting works which were caught during the Nord- 

 land Fishery in 1893. Of these measurements I add here a few which 

 I made in the stores of Mr. Lemkuhl at Bergen. 



ist sample assorted, as Kjebmandssildt (Tradesman's Herring . 12 

 chosen samples caught in Nordland, September 1893: 



250, 250, 245, 235, 250, 250, 250, 250, 238, 250, 250 and 238 mm. 

 which one will see are ver}" uniform sizes. 



2nd sample, assarted itAIiddelsildi Average Herrings) caught in 

 Nordland, September 1893: 



245, 244, 240, 242, 250, 230, 250. 240, 240, 240. 250, 240 mm. 



jrd sample, assorted »Stor Kristianiasild v. Large Christiania Her- 

 rings), caught in Nordland, September 1893: 



238, 240, 22Z, 230, 248, 230, 238, 240, 230, 232, 228, 232, 233 mm. 



4th sample, assorted ^ ^-stregs silda. (Five Point Herrings), caught in 

 Nordland, September 1893: 



195, 190, 200. 190, 200, 190, 210, 188, 185, 190, 195, 194. 



»4-stregs sild Four Point Herrings, .Liden Kristiania Sild« 

 (Small Christiania Herrings', were, according to report, of the same 

 size as 5 stregs sild i (Five Point Herrings), y only fatter and heavier.^ 



From the measurements it will be seen that the sorting between 

 »Kjobmandssild, ^ : Middelssild and »Large Christiania Herrings is not 

 made according to the length, and all my other measurements confirms 

 this, the sorting being made, as the warehousemen, too, always have 

 stated, according to the weight, and quantity of fat on the herring.
