of the Salmon in Freak Water. 69 



In drawing conclusions from these figures, it must be remembered 

 that fish of from 8 to 10 Ibs. were asked for, but as the supply available 

 was limited, the size of the fish sent was not specially regarded by the 

 senders. Fortunately, the question has been elucidated by the investiga- 

 tions at Berwick-on-Tweed. The following Table shows the results 

 obtained from the examination of female salmon as given in the Fishery 

 Board Report for 1895, pp. 64 to 72. 



TABLE XI. 



Showing Average Length of Fish in Kstiiaries : 



FEMALE FISII, 1895. 

 (a) Fish from B&rvnck-on-Tweed. 



In seven of these the ovaries, liver, and muscle thick and thin were 

 weighed. The percentage results obtained agreed generally with those 

 obtained from fish caught in the various estuaries during 1896, but as 

 the weight of muscle per fish of standard length was not determined 

 it is unnecessary to give the results of these analyses. 



(6) Fish from Montrose. 



So far as I am aware, all the fish received from Montrose were 

 captured in the lower waters of the North Esk or in Montrose Bay. 

 They are therefore to be considered as estuary fish and compared with 

 the estuary fish of 1896. 



Table XII. gives the length, weight, weight of muscle, and weight of 

 ovaries. 



A comparison of this Table with Table 1. (p. 64) shows a close correspond- 

 ence, and bears out Conclusions 1 and 4. As regards the growth of the 

 ovaries, it is to be noted that in the North Esk fish in July the ovaries 

 were more developed than in the July and August fish of 1896, but that 

 their average development did not exceed the greatest development 

 observed in the 1896 fish. In the later months the North Esk fish have 

 a somewhat less average size of ovary than the 1896 fish.
