 (See the tables). The fish in these tables are caught just in order to get 

 information of all sizes of plaice (also the small) which may be pointed out 

 in these seas. On that account prawn-catchers of bobinet, plaice-seines with small 

 meshes, and Ammodytes-seines (of a peculiar coarse sort of linen from the Skaw) 

 have been used in catching them. A few times we have tried to supple- 

 ment the researches by the purchase of larger fish from the fishermen, who 

 as a rule do not catch the small individuals. (See for instance table VI, 

 column 3). What sort of fishing-tackle we used is generally indicated in 

 the tables. — For further information as to the character of the fishing- 

 tackle, I shall mention that prawn-catchers are used while wading on the shores, 

 and are fit for catching very small young flat-fishes; the larger ones gene- 

 rally are swimming too quickly. This is clearly seen in table III, column 3. 

 — Ammodytes-seines can catch both small and large fish, but not so great num- 

 bers of the latter as the plaice-seine -with small meshes, which, as the water 

 more easfly passes through its meshes, is capable of being moved more 

 quickly along the bottom; on the other hand the plaice-seine cannot catch 

 the very small flat-fishes (under c. 2 inches in length) except quite excep- 

 tionally. Ammodytes-seines and plaice-seines with small meshes can both be used, 

 partly from land to be drawn towards the sea-shore, partly as »Snurrevaad« 

 from a vessel lying at anchor on the sea on any depth. — By combining 

 the use of these three sorts of fishing-gear we have succeeded in getting 

 good information of all the present sizes of plaice (and other flat-fishes), 

 as shown in the tables, both in the Gattegat 1891 — 93 as also, with the assi- 

 stance of Lieutenant Hansen, in the Baltic Sea properly so called in 1893, 

 table VII — VIII. Further there is information of the size of the plaice 

 from the places where the Biological Station has been anchored up during 

 these years, viz. the Lesser Belt and the Great Belt, table II, and moreover 

 much information of a more varied kind in the section » Researches No. 

 1 — 238«, which has not been included in the tables. Further, in table V, 

 column 3 — 9, I can give information of the plaice which are caught in the 

 Limfjord by the fishermen with various sorts of fishing-gear, with small 

 as well as with large meshes — information which I ove to Mr. Tranum. 

 Finally, in table V, column 10, is shown the contents of plaice in one draught 

 with an Ammodytes-seine, as this fishery is carried on at the SJcaiv. We have 

 then here really considerable materials (many thousand fish), which cannot 

 be denied a certain demonstrative power, even though we must be very 

 careful, as always when we have to do with fishery, especially when we
