Monthly Catches. — From the same statistics Table I. has 

 been obtained. The quantities landed each month of the year 

 during a period of five years, 1907-1911, are given. From these 

 the mean quantity for each month has been calculated in order 

 to show the months during which the greatest quantities are 

 landed. These are clearly from September to January. The 

 smallest quantities being landed from March to July. 



TABLE I. 



By means of statistics, kindly supplied by the Board of Agri- 

 culture and Fisheries, it is possible to show that the results 

 obtained above are not altogether due to an increase in the 

 number of vessels fishing for Nephrops during the winter 

 months. In Table II. the quantity in cwts. landed during each 

 month of 1911 by vessels which have been absent on a voyage 

 not exceeding one day in duration, and the number of such 

 landings are given. From these the mean quantity for each 

 landing of one day's catch has been determined. It will be 

 seen that, on the whole, during the months when the greatest 

 quantities were landed the greatest catches were made by 

 individual boats. The figures are taken for vessels which have 

 been absent on a voyage not longer than one day, because in 

 summer when the trawlers are absent more than one day it is 

 seldom that the whole of the time is spent on the prawn ground, 

 this region generally being fished the day before landing.
