Reoring of lobsters 



The purchase of spt.wn lobster started on June 7, 1937, nnd v;r.s 

 finished on July 3e We hrvd then bought c little more than 700 lob- 

 sters» The supply v>rris, contrary to earlier years, very Inrge^ so 

 that vfe could have obtained much more thnn vre could usee 



From. June 25 to August 21 v/e g rt about 600,000 young 

 Of these the following were liberated 



at once due to lack of sj>ace 75 .,000 



Left for further rearing,, about 525,000 

 Of these, reared to ith stage 62,500 



Reared to 3d stage 4.^.000 



You will see that the supply of young xn.s quite good^ but as 

 we obtained the essential part of the ?iatching in the course of six 

 days, botvreen July, 25 and 31, the hatchery vms overloaded T/ith 

 ■young and the net result of the rearing was therefore not as great 

 as it could 'have been. If vrehad had some more hatching boxes, 

 the results v/ould have been much larger. 



This year there ivas a great nuiaber of spawn lobsters in 

 Sl^rlandet (southern part of the country), and there vras comparative- 

 ly many eggs on the lobsters. We got about IjOOO young lolsters 

 from each spavra lobster this year, a result which we regard as quite 

 goodo But also this year we had a good deal of the earlier mentioned 

 parasite Eiohelotaj liov:e^7or, this v:as not so nuiaerous that it had any 

 harmful effect on the hatching work. The' yoiing lobsters v: ere let out 

 in the Krager3 district.

Note: This article was not translated completely. A 

 suraE:ary follows: 



Work in hatching lobsters was begun in 1883. It was continued 

 in 1884. Too high tei.iporature led to poor results. In 1885, hatch- 

 ing was successful. Also some lobsters vrere reared. One of the big 

 causes of death was cannibalism.
