DISCOVERY REPORTS 



A reshuffling of these weight data, with the addition of corresponding numerical values for the fish 

 categories, is given in Tables 43 and 44. These permit direct comparison and contrast of the three 

 regions, considered as possible fishing grounds ; but for a full appreciation of the possible implications 

 of these, the reader must refer to the general account of the region given in the introduction, and to the 

 individual accounts of the more important species given in the body of the paper. It is hoped that the 

 table of contents will make it possible to do this without the necessity for reading through the whole 

 report. 



Table 43. Further analysis of zveight data: occurrence, relative numbers and relative zveights of 



the main fish categories in each of the three regions 



Table 44. Further analysis of weight data: mean numbers, mean weights and relative zveights per 

 hour's trawling of the main categories, in each of the three regions 



* Almost negligible in northern region except for Palinuricthys (useful) at one station. 



f Mainly large numbers of the tiny flatfish Thysanopsetta, too small to be of value. 



I Of some importance in the southern region — sizeable Macrurids, Falkland herring, Parana signata. 



CONCLUSIONS 



In the exploration of natural resources the primary function of the naturalist is to provide fundamental 

 information on the nature, quantity and accessibility of the raw material. Thereafter the administrator 

 and technologist are in a better position to assess the prospects of commercial development. It is felt, 

 however, that a report such as this would be incomplete without some practical suggestions from those 

 who have collected and collated the biological data. In the remarks which follow, I am confident that
