These tables show that the great majority of fish investigated were 

 from 12 to 13 f inches in length. 



The Lowestoft and Ilamsgate samples closely resemble one another in 

 size, the latter having a slight preponderance of the larger fish. 



The samples of smallest-sized fish were those from Plymouth and

 fish below 12 inches in length, a percentage much higher than that in 

 any other of the local samples. The percentage of fish above 13f 

 inches in length is also excessively small in these two samples, being
