An Investigation of Albacore 



Purpose 



To clarify the habits of albacore by conducting a biological study 

 of albacore caught by the Fuji Ivlaru. (_ TN: research vessel of Shizuoka 

 Pref.V 



Results 



In order to determine the food of albacore, more than 70 fish were 

 examined. Almost all of these albacore contained sardines, ami / TN: 

 %sis ./, squid, octopus, and other common food. Fish 7'hich had ingested 

 fish bones, scales, and pieces of radishes and carrots (possibly thrown 

 overboard from fishing vessels) were also found. 



Judging from the condition of the gonads of albacore in January, June, 

 and from August to September, it may be assumed that albacore spavm around 

 November. 



Note: Fishing grounds covered by the Fuji iiaru are as follows: 



Although Mr. Hascgawa / TN: biologist v/ith Shizuoka Prefecture Fisheries 

 Experiment Station_7 believes that the spa'vning grounds of albacore are 

 possibly located near the Midway Island 3 in v/aters from 26°-27° C., this 

 has not been yet confirmed. It is thought that the femiale releases over 

 300,000 eggs at a single spavming and that these eggs arc pelagic.
