week in the »Deutsche Fischerei-Zeitung« what German trawlers (having visit- 

 ed, among other piaces, the Skager Rack) bring to land at GeestemiUide and 

 Bremerhafen. We do not get any closer information, certainly, as to the 

 fishing-grounds, but from my personal knowledge of the matter I may presume 

 that Skager Rack in this case meaus the Skager Rack uear the Skaw. 



From this souree it may be stated that a steara-trawler after a single 

 voyage to the Skager Rack, of c. 8 — 10 days, eau bring home 100 — 200 — 400 

 cwt. of fish of the foUowing species: 

 Of haddoclc {Gadits ceglefinus)* ofteu 70 — 120 cwt. 



- cod ( — caUarias)* - 30 — 



- green cod. ( — virens) - 11 — 30 — 100 — 



- haJce {Me7-h(cms smiridus)* ■ ...12—20-40—50—160 — 



- Ung [Molva vulgaris) - 8 — 



- the pole dah [Fleiironecfes ci/noglossns)* - ... .15 — 20 — 30 — 70—80 — 



- plaice ( — platessa)* - 18 — 65 — 80 — 



- hrill [Bothiis rhombns) - 8 — 10 — 



- turbof ( — maximus) - 4 — 10 — 



- sole (Solea vulgaris) - ■"/, — 



Moreover the following fishes are soraetimes caught by the hundred- 

 weight: Raja s/j. (12 cwt.), Argentina silns (14 cwt.), Clupea finta (16 cwt.), 

 shurlcs, lialibut [Hippoglossus) , cat-fish [Anarrhichas) , gurnard [Trigla sp. sp.), 

 Norwai/ haddoch (Sebasfes): besides a few salmon (Salmo sp.) at 10 Ibs. the piece. 



The five species marked * form by far the greater part of every trawler's 

 catch in these regions. Of these 5 agaiu the haddoch and the pole dab are the 

 commonest. — It is a matter of course that a nuraber of other smaller species 

 of fish are caught in the trawl, which are not uamed in the said periodical; 

 they have no pecuniary value, and do not occur either in greater numbers. 



The following 7 species of fish are here for the first time introduced 

 into the Danish fauna: Careproctus Reinhardi Kroycr, Gctdus Esmar- 

 Idi, Gadiculus argenteus (.unoiieiiot, Lgcodes graciUs sars, Lycodes Sarsii coueit, 

 Raja circularis, Raja lintea. 

 The Lycodes of 1897 have been determined by Professor R. Collett. By 



Petersen's investigatious in former years in the Cattegat a siugle Lycodes had 



already been found, but not till now the species has been determined. 



Professor Collet! has in »Videnskabernes Selskabs Skrifter 1898« rendered 



an account of his determination of L. Sarsii. 



When Petersen in the summer 1897 assisted Dr. Johan Hjort in a series
