most cases been given in detail. This material will give us some idea of the 
quantitative relation and quantities of the different sizes of the plaice landed in the 
various countries. Our conclusion will depend, however, on the extent to which 
the fish measured are representative: i. e. how far the composition of the samples 
measured is the same as that of the total quantity. When the fish landed on the 
markets is arranged in different classes, as large, medium and small, the work of 
determining the quantities under and above a given size is very much facilitated. 
“The statistical material will also permit us to report on the size of the plaice 
landed in general, as also on the variation in size in the different months and on 
the distribution of the various stages over the fishing grounds. 
“The statistical material at the Bureau’s disposal concerning the total quan- 
tities of plaice landed is summarized in Table II of Appendix C. The Table shows that 
monthly returns of the plaice landed have been obtained for the principal markets of 
Belgium, Denmark, England and Holland as also for the markets of Geestemünde and 
Bremerhaven in Germany. In these returns the quantities of plaice are given under 
three classes, or the small plaice is registered in one class and the medium and 
large plaice in another (Geestemtinde and Bremerhaven): It is evident, that the 
more complete and trustworthy the statistics of the different countries are on this 
point, the more valuable will be the results from the material concerning the 
destruction of undersized fish. 
“It is necessary, that the measurements of plaice should be continued regu- 
larly for some time, so that we may have a definite and reliable basis from which 
to estimate and compare the quantities of small plaice landed year by year. It is 
also very desirable, that the system of measurements should be extended to other 
species, especially the sole, turbot, haddock and cod. 
“The Bureau has entrusted the elaboration of the statistical material to the 
Biological Assistant, Dr. H. M. Kyze. The experience of the past year has shown, 
that additional funds will be required by the Bureau in order to CHE on this 
work in an efficient manner. 
“A first report on the elaboration of this material is printed with this Proces- 
Verbal as an Appendix (Appendix C).” 
The General Secretary stated, that the method the Bureau intends to employ
