water, with shrimp nets (one of Ijobbinet, witli veiT fine meshes, another 

 witli more open meslies, it mm from knot to knot), and nearly always by 

 wailing with the nets, i. e. when tlie water was sufficiently low; which was 

 generally tlie case in all piaces where the fry of the year occurs in this 

 season. The piaces which are specially suited for the occurrence of the fr}' 

 of i)laice are flat sand-hanlcs with shallow water (2—3 feet), which can be 

 heated through by the sunbeams, and with a clean, sandy bottom without 

 any vegetation and without any great interspersion of organic substance. In 

 piaces where the shore was so steep that it was impossible to wade, we 

 made use of a shrimpuet from the joUy-boat, kept in place by a man in 

 the stem, while another man was rowing. In this way we sometimes 

 caught pretty much, though never so much as when we were wading, when 

 it was much easier to give the apjiaratus the suitable speed, so tliat none 

 of the larger and quicker young plaice could escape. Later in the year, in 

 the end of August and in September, we also employed, now a bait-seine 

 with very small meshes, now a small-nieslied ammodytes-seine ("inchseine") for 

 the catching of young plaice. From these investigations, the results of 

 which are partially to be seen on the map, p. 8 and table II, we learn 

 more particularly the foUowing. 



On the Occnrrence of the Fry on the Sea-shore on Low Water. 



On the Shores of the Cattec/at we found the fry of plaice everywhere 

 where we were looking for it, except where too much fresh water from 

 rivulets is intermixed. In sucii cases it is replaced by the fry of flounders, 

 tor instance at the mouth of Mariagerfjord where, otherwise, the bottom 

 is excellent for the fry. 



In the Little and the Great Belt together with the adjoining seas (the 

 archipelago south of Funeu and the Langelandsbelt) the fry is found every- 

 where in suitable piaces, with the sole exception of Marstal Sande where, 

 moreover, the fry of the year of flounders is not found either. If we now 

 go easttvard to Siudalandshavet, the number of the fry decreases. At Fejø 

 we found c. 2;"), at Glænø some few, at Knudshoved 1, and farther eastivard 

 none at all, neither in Grønsund nor Ulfsund. At Rødsand and S. of the 

 isle of Møen') at Klintholm harbour there were excellent sand- banks, but 

 not one young plaice was found here, nor did we tiud any on the northern 

 shore of Møen, in Faxebugt, Køgehuyt, or on the shore of Amager. We may 

 say, therefore, that the fry of plaice was missing in the Baltic Sea prope/>- 

 and in the sonthern part of the Sound. We meet it again in the northern 

 part of the Sound, from Straudmøllen, but here as well as more northward 

 in the Sound in small number.-i only. 



The Isefjord. The fry is found here only just at the mouth of the 

 fjord; higher up in the fjord it is quite missing. This is the case perhaps 



') OfE Bøtøgaard, in South-Falster, on the 4. Septbr., we caught a young plaice, 

 8 inches long, on 1' , fathom of water.
