The Skipjack Fishery 



In putting a skipjack fishery into operation the first essential 

 is to understand clearly the habixis of and other facts about the fisho 

 What it has been possible to learn about the skipjack's habits is actively 

 made use of in the fishery, and methods are devised to take advantage 

 of the weak points cf the fish^ The thing to do is to direct the main 

 force of one's attack tov/ard the weak point cf one's opponent and at one 

 stroke attain success in fishings In Chapter I we traced the changes 

 in fishififa -uthods from ancient times to the present dayj, provided materials 

 for critici.'.ing them, and discussed features which should be corrected. 

 In Chapter II we considered the natm^e of the skipjack and discussed the 

 rationality of the old methods of operation in the skipjack fishery in 

 order to give some indications cf the course to be followed in the futi^re„ 



The author, vihc has presented the foregoing material as data to be 

 us.-d in understanding the character of the fishery in its present advanced 

 5="ate, feels that there is still a necessity for criticism and discussion 

 of som.e of the basic premises. To be specific, these are the charac- 

 teristics of the skipjack fishery^ 



(1) The skipjack fishery has been spread all over the country, and in 

 each locality it has its cwn peculiar historyo As a result, studies of 

 all sorts were made in each region separately, conclusions were drawn, 

 and the people in these arear. believe in those conclusions and identify 

 themselves with the-.i„ The fishing grounds have been epochally extended, 

 but people will not lend an ear to conclusions based on the combined
