want ot' u steamer especially was greatly felt, as tlie vessel at the disposal of the 

 Biologicai Station at that time, a transport-boat of the fleet cailed »Stationen«, 

 though well-fitted up with laboratory, well and store-room, had to have a special 

 steamer of the navy to tow it each time it was moved. 



On account of these difficulties in changing from place to place, the Di- 

 rector in the spring of 1901 decided, to moor »Stationen« in Fænø Sound in the 

 Little Belt. Tlie current runs so strongly there, that townetting can be carried 

 on pélagically by merely hanging the net over the side from the anchored ship, 

 and the surface-water is usually of a sufficiently high salinity to float the pelagic 

 eggs and newly hatched larvæ. 



From April 1891 uutil September 1892 the investigations were being 

 carried on in Fænø Sound. They furnished a rich collection of pelagic organisms, 

 as also of the eggs and young of fishes, so that in 1892 the Director was able to 

 publish a review over the pelagic Ufe in Fænø Sound during the twelve months 

 of the year (Biol. Stat. Beretn. III). 



Ou the couclusion of the 1891 — 92 investigations in Fænø Sound, the 

 Biological Station was engaged in other directions for a number of years, but in 

 1899 the Director again took up the interrupted investigations on the pelagic 

 eggs and young of fishes, with the special object in view of carrying out simid- 

 taneoiis ohservations at differeiit jdaces in the Danish ivaters. The method of procee- 

 dure had therefore to be diff urent from that used in 1891 — 92. The Biologicai 

 Station was not yet in possession of a steamer, and was thus unable to make the 

 raany necessary collections by itself. Other means had therefore to be eraployed, 

 and most of the gatherings Avere taken from a number of lightships, which were 

 specially suited for the purpose on account of their proximity to deep channels. 

 Vertical hauls with the pelagic net were taken twice monthly and the gatherings 

 sent in to tbe Biological Station. Wheu these collections had been continued for 

 two years, April 1899 — April 1901, they were brought to an end and the material 

 was theu worked out. The results are published in »De danske Farvandes FlanMon 

 i Aarene 1898—1901, I -II« (D. kgl. Vidensk. Selsk. Skrifter, 6. Række, natur- 

 vidensk. og raath. Afd. XIII, 3.). The first portion, written by tbe Director, con- 

 tains a section on fish eggs and young, based ou tlie collections mentioned. The 

 number of eggs and young in each gathering is given in the form of lists, the 

 determinations being added so far as they could be made. 



In the spring of 1902 Fænø Sound was again cbosen as the mooring- 

 place for »Stationen«, but as the Biological Station now had a steamer at its 

 disposal, the investigations were extended so as to embrace, not only the neigli- 

 bouring portions of the Little Belt but the other Danish waters also. The methods 

 were also improved; es]jecially was this the case with au excellent apparatus for 

 the capture of fish young, constructed by the Director and described under the 

 name of Petersen' s i/oiing-fish-trawl by Dr. Jobs. Schmidt in »Fiskeriundersøgelser 

 ved Island og Færøerne i Sommeren 1903« (Skrifter udgivne af Kommissionen for 

 Havundersøgelser Nr. I). 



From March 4th to the 22nd of May 1902, »Stationen« was at Fænø 

 Sound. »Bobbin« tow-nets were employed, huug from the boat's side in the 

 current and usually emptied and hung out again several times in the day. Now
