RESULTS OF SALMON MARKING 83 



Helmsdale fish took 506 days to increase 10 lb., 

 nearly double the increase, but in almost six times as 

 many days. Probably, however, the second fish had 

 spawned in the interval. The majority of the coast 

 recaptures show movement in the opposite direction 

 from those two similar records. Five fish have 

 followed a very similar course in going from the 

 Deveron right round out of the Moray Firth in an 

 easterly and southerly direction to the neighbour- 

 hood of Aberdeen. The intervals between marking 

 and recapture are 88, 109, 122, 126, and 187 days, 

 and the increases in weight respectively 4j, 3f , 2f , 

 9, and 4|- lb. In the last-mentioned fish the 

 estimate of weight could alone be obtained, as the 

 mark was not noticed till the fish was displayed in 

 a fish shop in Newquay, Cornwall. The increase of 

 9 lb. in the kelt weight in four months is consider- 

 able, more especially since the fish was a 16 lb. male 

 kelt when marked. 



Twenty coast recaptures are charted in the twenty- 

 fourth Annual Report of the Fishery Board for 

 Scotland, and of these, fifteen show a southerly and 

 easterly and only five a movement in the opposite 

 direction. It is unwise to lay too much stress upon 

 a result which after all is deduced from a limited 

 number of recaptures, but the trend of the currents 

 corresponds with the direction in which the majority 

 have travelled. 



Before completing the records which are obtained 

 from kelt marking, we have to deal with the fish 

 which are afterwards recaptured as kelts. These 

 fall into two classes : first the fish which have been
