nev;- apparatus for transportation of young lobsters. This is placed 

 affc on the motor cutter (vessel), but in such a way that it night 

 be easily removed v/hen vie do not need it# 



The transportation apparatus consists of a \TOodcn box vrxth a 

 cubic capacity of about 1,6 cu» meters divided into four rooms. 

 These are comparatively long in the fore and aft direction of the 

 cutter, but narrow in the other direction. This is to prevent too 

 much agitation v/hen the vessel rolls* 



The necessary sea water is delivered from a centrifugal pump 

 connected with the engine of the cutter. This, is led into the 

 transportation basin according to the same system which \ic have 

 in the re-ring apparatvis. Besides supplying the young lobsters 

 vdth fresh water it also provides the right motion in the boxes* 



It appeared that the apparatus functioned excellently in the 

 preliminarj- experiments while the vessel was lying at the pier;- 

 there was no opportunity for a larger transportation because we 

 lacked the sufficient number of young lobsters t Further, experiments 

 were made by letting the young lobsters out by means of a rubber 

 hose, 'i'his v/as used as a siphon an:', was so long that it vras lowered 

 to the bottom and dragged afbor the vessel. In this v/ay the young 

 lobsters went from the transportation tank directly down to the 

 bottom. By experiment it v;as proved that the young lobsters v/ere 

 not inj\ired by this method of release* 



On July 22, 1933, about 2,500 yoimg lobsters were in this way 

 let out at GjesBsanden (TromBy county).

Hatching work. Rearing of lobsters . , 



Purchase of spavj-n lobsters started on Juno 9 and terminated 

 on July 7o The supply wr^s scarce and we did not get the number we 

 vrantede A total of 50'"' spawn .lobsters were purchased from which 

 were gathered 248 /79(; you.ig?. 244,624 of these vrere used for rear- 

 ing; 50,777., ices,, 20^-3 per .cent wore reared to the 4th and 5th 

 stages • Some-vrere released, in earlier stages* 



To gather a sufficient ^numberj.pf^brood- for the planned trans- 

 portations to the Csiofjord, some of the 4th stagers vrere kept in 

 the aquaria so long bhat they changed shells once more and so 

 entered the 5th stage. Two shipments'- of young lobsters were sent
