REPORT ON HERRING MEASUREMENTS. 

 By W. Riddell, M.A. 



During the past year 19 samples of herring have been 

 examined, amounting to 1,068 fish. Particulars of these 

 will be found in Tables III-V. 



As some errors have been found in the tables published 

 in last year's Report, these have been checked, and the revised 

 figures are here re-published as Tables I and II. 



In Tables I and II, and sample (1) of Table III, the 

 length T is measured to the line joining the tips of the lobes 

 of the caudal fin when this is in its natural position ; A is 

 measured to the anus. After this, at the request of the Board 

 of Agriculture and Fisheries, these measurements were slightly 

 altered. T is now measured to the tip of the dorsal lobe of 

 the caudal fin when extended in line with the body, and A 

 is taken to the beginning of the anal fin. The other characters 

 are : — 



T.cd. Total length to base of tail. 



D. Length from tip of snout to beginning of dorsal fin. 



V. Length from tip of snout to beginning of pelvic fin. 



l.cp.l. Lateral length of head. 



K 2 . Number of keeled scales between anus and pelvic 



fins. 

 8. Sex. 



g. Condition of gonads on Hjort's scale. 



I do not consider that the measurements recorded up to 

 now present any definite evidence either for or against the 

 question of local races. 



There are differences between samples from different areas, 

 but samples from the one area differ just as much among
