answered. Even if these question sheets are returned, the answers are 

 as a general rule of doubtful value. 



The observations made last year on the KUddow and Eheda corre- 

 spond, according to the statements of the fishermen, entirely with the 

 facts observed by them for years, but they difier greatly in the tw^o 

 rivers. 



In the Kliddow, about 40 to 50 miles from the sea, the first ascending 

 salmon are usually noticed in August 5 but when the water is low, not 

 until September pr October; and only when the water is very high have 

 they been seen as early as June. The fishermen are very well informed 

 on the habits of the salmon during its ascent. In 1884: the period of 

 observation was limited to November and December; last year the 

 fisheries began in August and ended in the second half of November, 

 the largest catches being made during the first half of November. The 

 total number 0/ fish caught during the 4 months was 99, with a total 

 weight of 2,305 pounds; the average weight of the fish "was therefore 

 23.2 pounds. Of this number of fish 36 were males, with a total weight 

 of 1,012.5 pounds, the average weight of each fish, therefore, being 28.1 

 pounds. The maximum weight of the male fish was 44, and the mini- 

 mum IG pounds. Their length varied from 44 to 54 inches. The num- 

 ber of female fish was 03, with a total weight of 1,292.5 pounds. The 

 average weight was 20.5, the maximum 33, and the minimum 11 pounds. 

 Their length varied from 31^ to 47^ inches. No difference could be 

 noticed in the period of migration of the two sexes. The fish are 

 salmon and sea-trout. 



The conditions are entirely different in the Eheda. At the salmon 

 trap before-mentioned the ascent of salmon and sea-trout, which can 

 here be distinguished with certainty is observed all the year round. 

 During winter the trap has to be opened occasionally on account of ice 

 or high water, in order to save it from destruction ; but it is probable 

 that even at such times fish ascend the river. Very low water occa- 

 sionally renders the ascent of the fish difficult or impossible, owing to 

 the great quantity of sand in the mouth of the Stromming. In this 

 river also the governor of the j^rovince has permitted the catching of 

 salmon during the winter season of protection, so as not to hinder our 

 observations. 



The number of migratory salmon caught during the four months was 

 245, with a total weight of 1,558.25 pounds, the average weight there- 

 fore being G.3 pounds. Among this number there were 145 salmon 

 with a total weight of 982.5 pounds, the average weight therefore 

 being 0.8 pounds, the maximum 18, and the minimum 1 pound. The 

 total weight of the 100 sea-trout was 575.75 pounds, the average weight 

 5.75 pounds, the maximum 13, and the minimum 1 i)ound. As to sex 

 there were 144 males and 101 females. The largest number of lish as- 

 cended the river during the first half of July, both when taking all the 

 fish together, and when taking the salmon separate from the sea-trout.
