In the following table the relative numbers of dabs and plaice caught 

 during the two periods of investigation are displayed according to the 

 plan adopted for the other bays. It will be observed that during each 

 period the total number of dabs was generally less than half the total 

 number of plaice at each season of the year, the only important excep- 

 tion being in the summer quarter of 1902, when, as in the other bays, 

 there was a great relative increase in the number of dabs. This increase 

 did not, however, lead to the plaice being actually outnumbered, as was 

 the case in Start Bay. The fact that in Teignmouth Bay the plaice 

 always maintain their superiority in point of numbers over the dabs is 

 doubtless due to the perennial supply of young plaice from the estuaries 

 which open into this bay, whereas the young dabs do not derive the same 

 advantage from the proximity of these estuaries, owing to their less 

 restricted habits. It will also be observed that during 1901-2 the 

 proportion of dabs to plaice was distinctly lower than during the 

 previous period 1895-8 at each season of the year for which there are 

 corresponding records. This contrast holds whether the totals or the 

 large fish alone are taken into consideration. 



Table XIX., shoiving,for Teignmouth Bay, (1) the total proportion of Bahs 

 to Plaice, and (2) the proportion of Large Bahs (8 inches and upwards) 

 to Large Plaice (12 inches and uinvards), for each quarter during the 

 two series of investigations (Plaice = 100).
