The nevrly hatched young lobsters, about 41,000, were all 

 released in Flyi^de^'ii^en . 



The temperature in the rearing apparatus varied between 15ol° 

 and 18c7° Cc - the lobsters hatched early and the water was relatively 

 warm. Of the young reared in the aquarium, three lobsters are now 

 alive; they are 87, 50 and 39 millimeters long (July 29). These are 

 nov.' two years olda The difference in size is remarkable, as they 

 have lived under the same conditions all the tirae<. It is interesting 

 to note that the largest youn;-;; lobster now very seldom tries to hide - 

 contrary, to vriiat usuall;/ takes place* Is the reason that it has nov/ 

 reached such a size that it leaves its hidden life and starts creel- 

 ing about? And is this in accordance with conditions in natia-e? 



Also some young lobsters from 1925 were reared; of these are two 

 aliveg 51 and 45 millimeters long« (July 29., 192So)
