* 1 under 31 cm. 
Of the five samples from Yarmouth one came from the mid- 
summer fishery, and the others from the October-December fishery 
of full fish. The first sample, 7th June, from 11 miles E.S.E. 
from Yarmouth, was composed principally of fish with four and 
five winter rings. The size ranged from 26 to 28 cm. The two 
samples taken 20th and 27th October from 11 miles N.N.E. from 
North Haisborough Light and 12} miles east by north of Yar- 
mouth respectively, were very similar in size. Most of the fish 
were from 24 to 26 cm., but the latter sample. had more fish at 
26 cm. and larger. This was due to a slight increase in the number 
of fish.with five winter rings. 
The 29th November and 15th December were the dates when 
the last two samples were taken. They both had the majority 
of the fish between 26 and 28 cm. 
These samples contained older fish than those of October, 
but this does not account fully for the difference in size. The 
following data show that the November herrings had a larger 
size for age than those from the sample of 27th October.
