The experiments vj-ith the renrlng of lobster youn^j, rifhich took 

 place during the revenue year, are described in ITorges Kiskerierj

 gations, Vol» 111, IToe 9n The results of the exj-iorir.cnts T/ere 

 generally satisfactory;, the apparatus functioned v;ell, and the nc^-r 

 experiments vith vlifrcrert fo^-' for the brood led to solution of 

 this quest i '.-no Ox liver proved very satisfactory; it can be 

 supplied in sufficient quantity, it it; easy to handle, and the 

 y9i.m5 thrive on a liver diet. 



Durin^i the season about 24,000' neiTly .hatched lobster young 

 were liberated d.ue to lack of space, and about 21,300 r/cre 

 released in the botton sta'irc.

Reai ing of lobster di-irin;.; the svjmr ier 1928 



On June 28 a total of 200 spavm lobsters were purchased fron 

 a storehouse at Agerj/en© The lo''-'Sters vrere placed in the hatching 

 boxes the sane day, but the hatching proceeded sl'-arlyc 'le did not 

 get young enough to begin collucting until July 10; up to that day 

 the newly hatched young were released into the sea» 



• On July 13 the night watch started and therefore also the 

 ordinary work. 



As in the preceding season vve liave used ox liver and crabs, 

 the laitter proves to be the best, as it prex^ents the cannibalisn 

 better than the ox liver. The supply of crabs has been sufficient 

 during the last half ~f the season;, but the price has been high, 

 so that a crab diet is rather expensive* 



The apparatus have functioned vrell; the large rearing appara- 

 tus of concrete is, how^-verj rather difficult to work with, and 

 when wc again are going to buy new apparatus, \re shall go back to 

 the soruewhat smaller ■'.Toodcn boxes - but s oiiievdiat larger than the 

 present i<7ooden boxes.
