Appendix C 
First Report on the Statistical Material received by the Bureau regarding 
the quantities of small plaice landed in the various countries 
by 
EH. M. Kyze 
(With 12 tables) 
As the collection of statistics bearing on the question of the destruction of 
small plaice has now been carried on for more than a year and the material 
received by the Bureau is already very considerable, it seems very advisable to 
draw up a brief report at the present time in order to indicate the methods used 
in working up the material and the difficulties in the way of obtaining accurate 
results. The estimation of the total quantities of small plaice under any given 
size landed in the countries concerned will always be a matter of approximations; 
nevertheless, the endeavour should be made to lessen the amount of approximation 
as far as possible. As will be seen, the materlal to hand might be improved upon 
in many directions, and the purpose of the present report is, by means of working 
out the material from beginning to end as if it were the best obtainable, to suggest 
how improvements might be made. An estimate (Table III) has been made of 
the quantities of small plaice under certain sizes landed from the North Sea area, 
but this estimate does not pretend to be anything more than a first rough 
approximation. 
The general difficulties applicable to the material from all countries alike may 
be mentioned first of all before dealing with each country separately. 
Representative material: The first condition for an approximately 
accurate estimate of the quantities of small plaice landed is, that the fish measured 
should be representative of the fish landed. In this regard, some of the countries 
have an advantage over the others. In Denmark (North Sea), for example, only 
one class of plaice is landed, and the measurements of a number of samples of
