Good information concerning the distribution of the oyster when discovered 
in the Lim Fjord about 1350 is given in H. Krøyer's three reports to the Direc- 
tor of Crown Lands; his reports are of considerable general interest and may there- 
fore be reprinted here. 
H. Krøyer's Report. 1851. 
Ås soon as the Royal Commission, to whom the task was delegated of 
draughting improved legislation for the Lim Fjord fisheries, had completed its 
labours at Nibe, I betook myself without delay to Lemvig, in order to make 
investigation of the oyster bank said to be there according to a report to the 
Ministry from the Amtmand of the district Ringkjøbing, Greve Schulm. Ås the 
result of this investigation I beg to submit the following report. 
The small and narrow bay of the Lim Fjord running from north to south 
at the end of which Lemvig is situated, has a depth of three to four, even five 
fathoms at some places, but as a rule the depth is much less. The bottom is 
partly sand, sand and gravel mixed, large stones and partly also soft alluvial clay. 
Vegetation, of Zostera etc., appears here and there hut it seems to me not very 
richly. The water is of considerable salinity, so much so that a salt factory has 
been set up within recent years in Lemvig. On account of the sheltered position 
of the bay there can be no strong currents or collecting of the broken ice there 
in the spring. 
Under such conditions, so favourable to the preservation and production 
of oysters, I found if not an actual bank yet a by no means small number of 
oysters scattered or distributed here and there, not quite equally but in varying 
quantities, and it seemed to me that most were collected together on the west side 
of the bay (the side most sheltered from the currents), especially on gravelly bot- 
tom at a depth of four to six feet, with none on pure sand bottom. The size of 
the oysters observed here was considerable; I even believe that they were larger 
than any I have seen elsewhere in Denmark or in Norway. Very few of the spec- 
imens showed in their shells signs of old age, on the contrary, the majority 
were thin-shelled or might be considered from the nature of the shell 
as about three to four years old. The quality of these oysters will prove to 
be very good at the right time of year. On not a few I observe young oysters 
growing; on the other hand I never found empty shells; although the fauna in 
this part of the Lim Fjord has almost the same character as in the open sea 
or in other words, although almost the same small forms of animal life live 
in company with the oysters at Lemvig as for example on the Schleswig banks, 
yet I never met with many of the forms which are harmful to the oyster, namely, 
of star-fish very few and of crabs not any. 
In carrying out these investigations I was supported in the most friendly 
manner by Kancelliraad Voigt, Sheriff of the town and district, and it was due to 
his instructions and help that the investigation was both relatively easy and quickly 
brought to an end. 
The apparatus used consisted partly of an oyster dredge brought by myself, 
which however was found to be too small and light to be used with success on 
the hard gravelly bottom, partly an instrument something like an iron rake but
