FOREWORD. 



In placing the following paper before the notice 

 of those interested in Marine Biology the writers 

 desire it to be understood that the present contribu- 

 tion forms the first of a series of pamphlets to appear 

 at irregular intervals. The subjects to be dealt with 

 relate largely to the scientific and economic aspect of 

 certain fisheries, together with phases of Marine 

 Bionomics having more or less connection therewith. 



Applications for copies of the present paper may 

 be addressed to G. E. Bullen, The Hertfordshire 

 Museum, St. Albans.
