The brood xics fed regularly several times day and night. 

 Mostly we used hard boiled and minced eggs for food, -u'hich the 

 young ate with great appetite. Besides vre used minced, raw 

 mussels, two different kinds of shrimp (crushed), finely ground 

 boiled meat and finely ground rav/ fish. All this food v/as eaten 

 by the young with appetite, but we found out that eggs were inost 

 practicals as they made the control of the consumption in the 

 boxes easier, so that v;e could prevent pollution. The difficul- 

 ties in connection with artificial rearing of lobster are very 

 great, and very much greater in a large hatchery than in a small 

 experi:..iental h.atcheryo 



Experiments were also made with living food, ioe» small 

 Crustacea which vms caught in the sea by means of a dip net. But 

 the young lobsters did not try to get hold of them. 



The first difficulty is to get a sufficient nvimber of spavm- 

 ing lobsters. They had to be purchased at a very high price, as 

 the lobster dealers found out that "the average quality of their 

 stock decreased Y^hen the egg-bearing lobsters vrere taken out* 

 As the protection period starts before the vrork at the station 

 begins, all the spca'm lobsters Virhich we intend to use, have to be 

 brought in beforehand and stored; this leads to loss of eggs as 

 well as of lobsters. 



The nexb difficulty is to innlce the lobster hatche In 1913, 

 T;e used a method which was recommended in the report on the work 

 at the American rearing station at Rhode Island, This consisted 

 in putting about 20 spav^rn lobsters into a rearing box \7ith n 

 propeller. HoY/everj the method did not prove satisfactory, 

 because the lobsters lumped together in the corners of the box 

 and ate the sparm off each other. In 1914, therefore, boxes v;ith 

 separate rooms for each lobster v/ere designed. These boxes were 

 at first kept floating near the surface, but it appeared that 

 the lobster in one vray or another got hold of the nev;ly hatched 

 . larvae and ate them.. Probably the young vrere dravm in under the 

 carapace v/ith the respiratory water, which is released near the 

 front of the carapace, vrtiere any solid particles are caught by 

 the feather-shaped sides of the m.anillipeds and are eaten. Several 

 times T/e stated that lobsters in the above described position had 

 young in the stomach; the brood was in all stages of dismemberment; 

 (the chewing is performed in the stomachy vyhich is equipped with 

 tools for crushing of food). The boxes were therefore placed on 

 the bottom, so that the lobster could not catch the young j T/hioh 

 are kept floating by the rotatip-g propeller. 



Still we got very few young. Spoiled eggs soon appeared under 

 the rear part of the lobster's body. Such eggs are easily noticed 

 because of their scarlet color. Only during the first part of the 

 season did vre get some young from the spawn lobster v.'hich had been 

 bought near the stationo After tliree weeks, all the eggs vrere
