 inoretcsed vifith the present experimental apparatus o The latter had 

 finished its task; noviT wc have to go one step further and try to 

 increase the supply of lobsters in the sea; but for this purpose a 

 larger apparatus was required, vrhich v:ould be capable of producing 

 considerc^bly more youngo In anticipation of a grant for a new 

 appart'.tus _, the rearing of lobsters ivas therefore suspended during 

 the s-Lirjier 1930, 



Tlio i:arl:ing experiments mentioned in earlier reports have been 

 continued on a small scale, chiefly for the purpose of studying 

 specific questions concerning the biology of the lobster. Similar 

 to earlier years statistics hare been gathered concerning the catch 

 of certain lobster fishermen in the ristrict Mn.ndai-Krager8. This 

 first-hand statistical information will probably be of great 

 importance for the study of the variations of the lobster fishery.

Fl/devigen hatchery 1882-1932 



V Lobsters ppo 31-36 



Already in the construction of the yearly report for 1884, v:e 

 find the successful experiment in question, with regards to the 

 hatching of separated lobster spciVinic This is so much mere \7orth 

 reinarkable because at that time they thought that the external eggs 

 of the lobster had a physiological connection v.dth the mother animal 

 and could not be separated from her without arresting their develop- 

 ment o 



One opinion, which Prrfessor G« Oe Sars gave expression to; "You 

 may well try Danncvig ('s advice) j but I do not think it will v/orkc" 



In 1885, they ma.nrged to hatch m.any thousand young lobsters in 

 this manner anr' they Vi^ere fortuncte also in raising a lot of then 

 through the larval stage; certain ones v/ere kept until they v.'-ere 56 

 days old and thei_f habits recorded. 



They had a great deal of trouble raising then on account of 

 cannibalism; one youngster ate the other right along*
