The apparatus is described, and it (also, in addition) gives a 

 guide for those vrho would like to hatch out the young lobsters and 

 raise then. Yilhat has been said here (in the report of 188 i) v/ill 

 benefit nen to notice to this very day. 



It "•.vas especially the question of hatching that interested ny 

 father - he thought that the eggs laid in the epring should be taken 

 fron tht lobster before it was exported* VJ]rien the young had been 

 hatched and retixrned to the ocean tliat shor/ed a distinct advantage 

 over exporting with lobster and eggs together. 



Economic difficulties j hov/e-'er, hindered the continuation of 

 the work in great lae^sure until 1892, when the hatching and rearing 

 vras resumed in tl^e new (political) set-up. 



The \Tork continuos in order to find thf; best living conditions 

 for the lobster young; it estoblishcG, for one thing, which salinity 

 is best, — end what influence the tenperature has on their developnent . 

 The vrork proceeds very well, but may well be entirely suspended since 

 Fl/devigen has no authorization to do it. The \Tork v;ith lobster 

 culture is apportioned to Stavanger under the leadership of Dr« 

 Appell/f , of the Bergen nusouris 



In 1914, the present director of Fl/devigen received a request 

 fr on trie Director, of Fisiicries, to ta]-:e over the lobster cult-ye here 

 in this country, /.t this tii.ie it is the rearing that is iuportant* 

 JLfter a great :na.ny unsuccessful experiences with an apparatus after 

 the ijaorican patterns it (Ai.ierican apparatus) had to be abandoned. 

 Instead they continued with difficult laboratory experinents to find 

 out the best living conditions and the best raethodg. After an infinity 

 of experiments, more or less unsuccessful, the problem was cloared up, 

 little by littleo The difficulties were:- to furnish quickly adequate 

 circulation of seavnter vdthout injuring the young; to get the 

 apparatus cleaned; and to furnish the proper foodo 



In 1922, they established a worlcrble method. The main idea vras 

 that the stream (of sea water) was introduced into the apparatus in 

 such a Y.'ay that the water rotated around a horizontal axis. In this 

 manner the yoiong which gathered in the center in the calm area 

 (doldrums) little by little vro-ald sinlc into the rotating stream of 

 water r. Vlith the American apparatus the stream rotated around a ver- 

 tical axis, with the result that the young gatliered at the bottom, 

 nerr the axis, whore it vras easy for them to be injured. The clean- 

 ing of the apparatus goep on now practically automatically and is 

 m.ore effective. It was ill luck that sh.ovrod us the way© During 

 the experiments at one time it v:as found that the -sea v/ater became
