THE BARENTS SEA ("WHITE SEA ") TO THE NORTH SEA. 507 



How rapid these individual growths are in comparison with those 

 of the North Sea fish can be seen by reference to any published report. 

 To illustrate this rapidity, a number of records have been taken from 

 the English marking experiments in various localities in the North 

 Sea. These have been put together in the form of a table, and fish 

 have been chosen which mostly resemble the five White Sea plaice in 

 original size, the sex being of necessity also the same. 



At the head of each of five columns is given the label number of 

 the White Sea plaice with its original size, growth, and number of days 

 at liberty. Below each comes a list of North Sea fishes marked in 

 the same way, and set out again in whatever part of the North Sea 

 they happen to have been caught. Comparison can thus with ease be 

 made by taking any of the North Sea fish and comparing the growth, 

 or period at liberty, given at the top of the column : —
