The stations W. of the British Isles marked on Chart T, were mostly investigated in 

 the month of June (1905 and 1906) but a few on the N., N. W. and W. of Scotland and 

 in the Straits between the Hebrides and Scotland are included for the end of May (1905 and 

 1908); also a larger number of the stations on the S. W. part of Ireland are for the middle 

 and end of May (1906) and the station at the mouth of the Moray Firth for 7th May 1905. 

 At the latter station a half hour's haul gave no less than 221 pelagic fry of the cod (the 

 majority had a length of about 1 cm.), which is a considerable number and indicates even 

 in comparison with Iceland and the Faeroes the presence of large quantities of cod. With 

 regard to the waters N. of Scotland the largest number of pelagic cod fry I have taken 

 per 1/3 hour's haul was 79, on May 21st 1908 at Station 3. 



Most of the stations on the W. of Scotl and which have given us pelagic cod youug, 

 lie in the Minch (Straits between Scotland and the Hebrides). Here we took, in a half 

 hour's haul on May 27th, 1908, 74 pelagic cod young, the majority of which were ca. 1 cm. 

 long; on June 27th 1906 a one hour's haul gave 166 which had a length of about 

 3—4 cm. and on May 27th 1908 (St. 10) 122 mostly about 1 cm. long were taken W. of 

 the Hebrides. Pelagic cod young occur regularly however in all our hauls off the west coast 

 of Scotland within the 200-meter curve. If we could thus so late in the year as the end 

 of June take so many large fry of the cod, there can scarcely be any doubt that we could 

 have taken largue quantities here earlier, i.e. during the spawning time. It is men- 

 tioned by British biologists (e. g. Mc Intosh and Masteeman, 1897, p. 241), that the bot- 

 tom stages can be found in the littoral zone already in June or end of May ; and this 

 appears also from a haul with the eel drag-seine we were able to make , with the kind 

 permission of the authorities, in Glumach Harbour at Stornoway (Hebrides) ^ 



It may be supposed however, that a considerable proportion at least of the many 

 young cod a little larger which were found on the northern part of the west coast of 

 Scotland, were spawned further to the south on this coast (perhaps even on the north 

 coast of Ireland and the northern part of the Irish Sea), and from there carried northward 

 by the north-going current. 



Ireland. In the latter half of May and the first half of June 1906, the south-western 

 parts of Ireland (Co. Kerry) were investigated rather thoroughly and gave the result that 

 the cod fry were there much more scarce than further to the north on the 

 Scottish coast. This applies not only to the pelagic stages but also to the bottom stages. 

 The occurrence of the latter was investigated in Valencia Harbour, which lies on the south side 

 of the large Dingle Bay, County Kerry. In 1906 the "Thor" passed several days in Valencia 

 Harbour in May, June and the end of August, partly for repairs, partly on account of the 

 bad weather. With the kind permission of the authorities we were able to utilise this time 

 to a thorough investigation of the inner waters round about in the littoral region. A 

 large number of hauls was thus made with the young-fish trawl, a small narrow-meshed 



' The seine was dragged to land from a depth of 29 meters ; the temperatures at the bottom and 

 surface were respectively 905° and 9-15°. In this haul 16 cod and 28 coaliish of the following length 

 were taken; 



Gadus callarias 



Gadus virens 



No. 14432321441 

 The cod were in the tessellated stage.
