suitable. for pltiiee iu this wak'r; Imt il it Ijreuds iii tlicri', \\u .sliall alsn t'eed 

 tlie fisli of the two preceding yeais. Tliis diiuinishes tlie productivity some- 

 wliat, and certaiuly niucli luore tliau llie traiisplantation will eust; iiioi'eover, it 

 would be uecessary then to sutter u uuiiiber of plaice to grow uji to a larger 

 size thau 1 Ib., wliicb at present, no doubt, it is the most protitaltle to ])roduce, 

 and, tinally, we could not tlien regulate the number of plaiee in this expansion 

 of the Fjoi'd. The number might now ))e too small, now too large, and in 

 the latter case the result would be a production of many, but small and 

 (heap plaice. 



The size that gives the greatest pecmiiary protit depends nn the current 

 ])riees. If a plaice of 1 Ib. fetches tiie higbest price wbicb oii the \\liole is 

 paid for this iiieat, I sliall propose to begiu with a yearly transplantation, so 

 that the lish are carricd in tbere in spring and fished np in the eourse of tlie 

 same autuiun and winter. 'i'hey liave tlien reached a weight of c. 1 Ib. and a 

 length of c. lo — 14 indies to the tip of the tail. At present tlie few tish that 

 are transplai^ted grow so ([uiekly that this ean be done. Hmr »laiti/ fish there 

 ran grow up so ([KicMi/ creri/ i/car is a ((uestiou to wiiieh the experiraent must 

 give the answer. 



1 shall not at all here eiiter iiito caleiilatioiis of liuw uiueli Thisted-Bred- 

 ning mav ))e able to produee in this w&y every year, but I should tl\ink, if we 

 waut to prodnce plaice of 1 Ib. a piece, that we inay try. at tirst, to place 5<t 

 011 each Tonde Land. If then these could gr<»w as ijuickly as the j)resent 7 per 

 Tomle Land, and consetjuently weigh 1 ll>. in the autumn, everybody ean judge 

 for himself what these c. o5U,U00 transplanted fish will be worth in the autumn. 

 The mortality will scarcely be great in this short time. 



it miglit be thougiit perha[is that .^uch a production would impair other 

 H.siieries in this e.xpansion of the Fjord. Of more considcrable ones there are the 

 eel and the cod-fisheries; but in other expansions of the limfjord, for instance 

 at Venø, tliesc tlirive pretty well togetiier with great plaice-fisheries, so tiiat I 

 eanuot think there is iiny serious causc for fear. -- Finally, it niight be said 

 that this transi)iantatif)n is no real ad\antage to our stock of Hsh, for it ouly 

 takes from one water (The Geriuan Sea) and give.s to another . I think this 

 objection is sutTiciently refuted by my ]ireceding remarks on the local over- 

 populatinii wliicli iiiay be supposed tn esist iu se\'eral i<\ our waters.
