Part III — Twenty -fifth Annual Report 



Fraserburgh, July 7, 1906. 



These herrings were caught 30 miles N.N.E. from Kinnaird Head, and 

 were of the class known as " Fulls." In the catch, however, which would 

 be about 25 crans, the bulk consisted of much smaller immature fish.

*The measurements (length and girth) are given in centimetres, and the weights in 

 grammes. The diameter of the ova is given in millimetres. 



The muscle of the male fish was also analysed, but the results of the 

 analyses were practically identical with the female muscle, and so will 

 not be given.

These herrings were sent by the fishery officer, labelled " Fulls," but, 

 as will be seen from the table, they were by no means fully developed.
