"The temperature of the vrater (in) the tarHc is that of sea

 is few. There are in the vjliole country 50 stations v/here they 

 appear. It is an apparatus easy to construct, cost a little and

The very active industry of lobster canning destroyed every 

 yeai- in Now Fcundland and Canada a considerable quantity of berried 

 fema.les. 



Thanks to the use of the floating incubator numbers of eggs 

 vrerc collected, more T;ith the aid of the super intendant of fisheries 

 of Nevj- Foundland than v.'ith the directors of lobstering themselves 

 and vrere able to be brought up to the hatching stage. 



It should not be necessary to believe, however, that the oper- 

 ations rendered with the use of the floating incubator do not 

 require any precaution. It is necessary that the latter be placed 

 in the regions v/here the vfater is as pure as possible and that they 

 (waters) be as approximately brisk and the eggs should be absolute- 

 ly healthy. It is also necessary that the apparatus be kept rigid- 

 ly clean and that they be visited frequently to disentangle the eggs 

 of the slimy particles which are able to pollute them. Finally, it 

 is necessary to remove from the incubators the embryoes (eggs?) 

 ViThich die in the course of development. Y/ithout these precautions, 

 it is to be feared that the pores such as the micropyle of the 

 vitelline membrane will be obstrticted by the elements in the course 

 of development and that the stopping of oxygenation may involve the 

 development of the embryo. 



The following Table (p« 156) gives us in a complete manner the 

 progress of operations effected at Dildo Island for the artificial 

 propagation of the American lobster (H. americanus.) 



In Canada, they continue, at the Bay Yxavr establisl-imont, to i;ise 

 the incubation ncthod used at first at Dildo and vfhich vras made to 

 develop fecund eggs in LfcicDonald jars. It is reported in the accounts 

 contained in the 28th Annual Report of the Canadian Fisheries Depart- 

 ment that the owners of the lobster factories appreciated already 

 the -influence of the release of fry effected thru the efforts of the 

 lobster station at Bay Viev/* 



The director of that station, at the time of the lobster fish- 

 ery, visits the coastal factories aboard a snail steamer fitted out 

 for this service. He brings back from the factories the eggs 

 removed from under the tail of the berried females vrhich have been
