2. Comparison of commercial and sport catches for certain species

Statistics 



Detailed statistics are the basis for the study and management of 

 our fisheries. In order to facilitate tabulation and to make available 

 the details of our fisheries data, the records since 1931 have been han- 

 dled by the system of punched cards. Monthly reports are prepared 

 for each of eight geographical regions of the State, showing species, 

 pounds, boat, dealer, price, locality of catch and point of delivery 

 segregated by : 



1. Species. 



2. Daily and monthly catch of each individual fishing boat. 



3. Pounds of each species handled by each dealer. 



4. Species and weights landed in each city. 



In addition a cross-reference index is maintained for all fishing 

 vessels and the yearly records of boat registrations have been tabu- 

 lated. Other records, such as commercial fishing licenses issued, are 

 systematically filed at the laboratory. 



The above activities have been organized into routine procedure 

 but in addition, most valuable assistance to the research and admin- 

 istrative work has been rendered by a variety of special reports made 

 up to meet a specific need, and the wealth of detailed information 

 made available by these special reports has justified the punched card 

 system for handling mass data. 



The following examples illustrate the wide range of information 

 made available by these special reports : 



1. Sardine boat catches for analysis of fishing effort. 



2. Mackerel catches by type of boat for past years. 



3. Tuna catches by boat type for each of the five species for past 

 and current years. 



4. Bottom fish trawl catches from 1924 to date to show species of 

 flatfish and incidental catches of other species. 



5. Rockfish catches and incidental species for selected areas. 



6. Water area yield tables for the most important species. 



7. Tabulations of marine sport catches by party boats, charter 

 boats, barges and from piers. 



Since equipment and trained personnel were available, the statis- 

 tical department has been charged with the compilation and report- 

 ing of: 



1. Hunting license applications and records of game kill. 



2. Angling license applications and records of freshwater angling 

 catches. 



3. Deer kill in the State.
