 . The decrease in the lobster populatioaa, which started in the 

 lost part of the 1880s and later on coati.nued for years, raised 

 the question whether anything could be done to increase the lobster 

 populo-tion and the steadily decreasing profit of the fisheries. For 

 this reason the Stavanger Branch of the Association fpr Promotion 

 of Norwegian Fisheries in 1891 asked for a grant of kr. 2,000 in 

 order to build a so-called lobster park at Kvitings/, so j:hat a 

 lorger number of mother lobsters could be put in there every year to 

 hatch their spawno One assuiTied thn.t the brood would grow up in the 

 park, then be put out in larggr districts, and thereby, contribute to 

 an increase of the lobster population. After the necessary money 

 had been grnntedj, the park vras started, and in 1892 it- was ready for 

 use. It is built in such a way that five larger or smaller rocks are 

 combined by walls which consist of big stones. At the beginning there 

 were two larger openings, covered with a net, in the walls, in order 

 to- let water pass throtigh into the parko These vrere, hoirever, soon 

 removed, as it appeared that there was sufficient water circulation 

 betv/een the park and the ocean outside through the holes in the vialls. 

 The bottom of the park is partly ledge, covered vrith brovm algae 

 ( Fucus and Lai'iinaria ) , partly mud, grovm vrith eel-grass (Zostera). 

 The depth is betvreen three and four meters at the most« 



The first year (1892) there vrere put into the park about 450 

 mother lobsters with external eggs which should be hatched the same 

 year, and in 1893' also more than 400 vrere put in after the populat- 

 ion from 1892 had been caught in the spring of the same year. . . . 



The purpose of my first invest igrtions was to find the differ- 

 ent stages of the lar^rae in the park,i and for this purpose a dip-net 

 was usedft We succeeded in finding, c lot of young, but we could never 

 get larvae other than those .of the first stages The same Investigat- 

 ions were carried on for two yecirs^.but always wdth the sarae result. 

 He also tried to catch young on, the bottom,^ but v/ithout result. In 

 1893 we tried to catch the one year old bottom stagers from 1892, 

 but vre did not succeed* The experiments in the park were then 

 stopped. However^ also in the following year, lobsters with external 

 eggs vrere put in there. 



V/lien I started ray experiments again in 1897 in the same place, I 

 caught some small sized lobsters, which in all probability had groi'm 

 up in the park. Similar things have happened later. It must there-
