Before I liavc had furtlicr <ip|Mn(,iiiiitrii>s to t^xaiuiiu', whctliei' these comli- 

 tions ot' the western parts of the Limfjord can be explained only by a suppo- 

 sition of a local overpopulation of })laice, I dåre not advise to rnake arrauge- 

 meuts liere to counteract uverpopulatiou, bul sliall pro tenip. only rocommend 

 t'xi>eriments with transplantation of plaioe from the German Sea. 



Before tids ipiestion of overpopulation is further elucidated, it will be no 

 oasy matter to regulatf the plaice-tishery in the western jjarts of the Limfjord 

 in the best way. The size limit that is suitable for Thisted will probably Ijc 

 too high liere. One tliing, however, seems to be advisable: to commence the 

 Kshing with plaioe-seines as late in tlie year as possible, for instance on the ]. 

 November, in order to give the tish as much time as possible to grow, if wc 

 will not (juite do away with this apparatus; now the plaice are tished up 

 already in the first half of September. 



The followiug is the tirst paragraph of the instruotious given by the Home 

 Department to the Direotor of the Biologicai Station: The object of the Bio- 

 logical Station is to acquire laiovvledge of all sueh matters \\ithin the science 

 of nature as mav be of moment for the development of pi'actical tishery aml 

 serve to elucidate (|uestions concerning our fishery-legislatioii . 



It must be supposed that the ubove will be of greut moment to the }>ra<'- 

 tical tishery. particularly in Thisted- Bredning, but we must sup[)ose also that 

 transplantation of plaice into Visby-Bredning, Liv- Bredning, and Louns-Bred- 

 ning. when carried out on a sufficieutly large scale, will have a similar intlu- 

 ence. — 1 shall not liere enter furtlier into the (|uestion, whether ther.e is any 

 probability of succeeding by this means elsewhere in our seas. It lies near 

 to think of the Issefjord, for instance, or the Sound between Ivlsinore and 

 Saltholm, the waters north of the isle of Funen with Middelfart-Sund, Kaløvig, 

 and sirailar seas. in enclosed fjords, overgi'owu with /ostera, such as Mariager, 

 we cannot expect any good results of transplantation, as proved by a small 

 experiraent in 1894; the plaice does not thrive well there. If there are /e«' 

 hiif lanjc plaice in a certain water, a good result may be exjiected; in that case 

 the transplanted plaice most likely will thrive and add considerably to the 

 number. '•') 



It is unito prtibalile tliat sm-ccsj^ful results mav ln' obtained l>y a siiuilar transplan- 

 tation of young tisli into iinr hiri/cr iriiterK, for instanco the Cattegat. Tiie object 

 liere must be to distriljute the fry artificially over the whole area that is suitable 

 for thb jrripwth of plaioe. It seoms as if tlic fry is only spread jn-oportionnlly slo« 

 liy iniiriation, so lliat large tracts probably are overpeoplcd with ymmi^ lish, uhile
