LOBSTER INVESTIGATIONS AT LONG BEACH POND, N.S. 



(A. P. KxiOHT, M.A., M.D., F.R.S.C., Professor of Animal Biology, Queen's 

 University, Kingston, Ont.) 



RECOMMENDATIONS. 



1. That the rearing operations hitherto conducted by the Board at Long Beach 

 pond be discontinued. 



2. That the executive committee consider the advisability of securing from the 

 Fisheries Branch of the Department of Xaval Service full control over the operation 

 of one of the present lobster hatcheries, in which to conduct a series of experiments on 

 the rearing of lobster fry, using warm sea-water, as suggested by Professor Macallum. 



3. That the executive committee confer with the department as to the best method 

 of collecting statistics regarding the relative numbers of male and female lobsters 

 trapped next season, and also the percentage of females carrying fertilized eggs. 



4. That several more enclosures be built at a moderate cost, by either the Board 

 or by the Fisheries Department at different points along the maritime coast, for the 

 purpose of determining more definitely the percentage of commercial lobsters which 

 extrude eggs in July and August. 



ACKNOWLEDGMENTS. 



Acknowledgment is due the Department of Naval Service for furnishing a plenti- 

 ful supply of both berried and commercial lobsters for the purpose of carrying on the 

 experiments described in the following report; also for placing at the disposal of the 

 Board the services of Mr. Andrew TIalkett. Mr. Halkett gave us every assistance. 

 More particularly, he kept an accurate count of the lobsters received at the pond, 

 allotted to the various enclosures, and returned to the sea. 



The Board is also indebted to the department for moving the rearing plant from 

 the southwest end of the pond, and placing it within the cement pound. 



POUND AND POND. 



In the following report the reader must distinguish carefully between the natural 

 pond of some 5 acres, and the artificial pound of about three-fourths of an acre, 

 enclosed by cement walls and forming the northeast part of the pond.
