APPENDIX J: HOLLAND

For Ymuiden, calculations of the income and catch of the trawifishing boats are 

 possible for the years 1900 — 1903 only. The items for the years 1892 — 1894, are of no 

 use: they are rough, too rough estimations. For the year 1895, no figures have been 

 published. For the years 1896 — 1899, figures are at hand; they inform us about the total of 

 the fish landed. But as this total is partly composed of trawl and partly of longline fish 

 and as the ships which landed the fish are partly longline fisherboats and partly trawlers, 

 but as no division is given, a c-alculation of the catch and the income pro boat has been 

 impossible for the said years.

For the years 1900 — 1903, the Ymuiden statistics inform us about the value and 

 quantities of longline and trawl fish separately; for these years, it is also known what the 

 income was for all the bumboats, all the coast-fishing boats, all the steamtrawlers etc. 

 which fished with the trawl and landed their fish in Ymuiden. As, moreover, the number 

 of voyages (not the number of boats of each category) is known, it has been possible to 

 calculate for these years, for each type of boat, the income per voyagé, as also the quan- 

 tity of some of the main fishes (haddock, plaice, sole and dab). These figures are given 

 in the two following tables, as far as those of Table LUI are concerned, without believing 

 that a really satisfying ^ result has been obtained. 



' The main error arises from the fact that it was necessary for this calculation to suppose, that the 

 catches of the different vessels are composed in the same way on an average. It is clear, however, that 

 this is by no means the case! As for an example the haddock occurs in the catches of the steamtrawlers 

 only, the smaller boats have more sole on an average etc.
