of the rearing str.ti.iii can be fully utilized. The developinent shcvj-s 

 the right tendency - we cr\n now count on about five /re production 

 expenses per individual in the botton stage. There is reason to 

 believe that it will be possible to reduce the expenses to a fract- 

 ion nf the fl^vre mentioned. But \ie cannot expect it to happen 

 in the near future. VJe need time .and money to carry on the 

 experiments. -; 



At this time I do not want to make any predictions as to \vhich 

 results we mij^ht be able to obtain. in the rearing. of lobster. I 

 •would rather tell about our attempts at getting inforlnation about 

 these things. 



. In the immediate neighborhood of the rearing sta.tion we 

 release varying quantities o.f young without any definite p-urpose. 

 lie must simply have a place to liberate the young v;hich\Te do not 

 use for our experiments. But more and, more we now chose certain 

 isolated districts wh'ere the brood is released according to a 

 definite purpose. In these places v/e get accurate information 

 about the catch of the lobster fishery from year to year, partly 

 together with measurement of both the regular and the small sized 

 lobster. In this vifay we will gradually obtain some accurate infor- 

 m.ati6n about these difficult problems. For the time being we must 

 .-content ourselves by working further on the theoretical basis of 

 ■the justification of the rearing, vmich I have mentioned before. 

 Some people point out that it is impossible to know anything aboiit 

 the advantage of hatching and rearing. Here I do not agi^ej the 

 more information ',76 get, the closer we get to the solution of these 

 difficult problems.' By intensive work we shall certainly reach our 

 aim.

Hatching work. Rearing of lol'Ster . 



On account of the high temperatiore of the sea water in the early 

 summer of 1933 the lobsters hatched their eggs about a; month earlier 

 than normal. In spite nf the fact that we vrere on the m.arket to 

 buy spavm lobsters at least K- days earlier than usual, it was there- 

 fore Impossible to buy a sufficient quantity of spavm lobsters. 



Jie started the rearing on June 29 with a supply of 139 spaym 

 .lobsters (56 kilograms) of which only a very few had a normal amount 

 of external eggs. The rearing therefore lasted only for a very 

 short time in order to procure young for some experim.cnts vdth ovr
