This detailed study on the life history of the autumn- 

 spawning saury population In the western Pacific is based 

 on data for 1959-67. A hypothesis is presented on the 

 yearly life cycle of the saury based upon sexual develop- 

 ment, feeding habits, and migration patterns.

 Information on migration patterns, sexual development, 

 spawning habits, and egg and larval development of the 

 Pacific saury, resulting from Soviet investigations, is 

 reported. Contrary to Japanese beliefs, this author found 

 that saury do not spawn until they are 3 or 4 years old 

 and that 5-year-old fish are common. Information regard- 

 ing migration patterns has limited value because of the 

 use of local geographical names. Sexual development 

 during the year are classified in a six-step scale, which 

 was not defined.

 The stomach contents of larval and juvenile saury 

 collected between October 1958 and March 1959 were 

 analyzed qualitatively and quantitatively. Newly hatched 

 larvae, 6 to 8 mm. long and planktonic in nature, are 

 indiscriminate feeders. Small planktonic moUusks, cope- 

 pods, Globigerinae, Tintinnidae, and sand were found In 

 their stomachs. Large larvae are active swimmers and 

 seemed to feed selectively on copepods. Juvenile saury 

 feed mostly on Clausocalanus .

 Seasonal variation of the fat content of saury was 

 examined during 1953-55. All body oils were squeezed out 

 or extracted with ethyl ether and weighed. The fat content 

 was high from the beginning of the fishing season (August) 

 through the middle of October. The fat content dropped 

 rapidly toward the end of the season (presumably late 

 November or early December).

Soviet attempts to develop a commercial saury fishing 



industry In the northern Sea of Japan and the Okhotsk Sea 



are reported. The author found that, in September and 



early October, the rate of southward migration depends 



largely upon weather conditions. Cold northerly winds 



resulted in a rapid southward movement of fish, and very 



poor commercial catches. These areas might be fished in 



August.

 Thermal stratification patterns are considered very 

 important in saury fishing off the coasts of Russia and 

 northern Japan. The author believed that southerly winds 

 create strong thermal gradients at the current junctions, 

 resulting in good fishing even on moonlight nights, whereas 

 irregular or northerly winds result In poorly defined 

 thermal gradients and less productive fishing.

Techniques of operating various types of alluring light 

 in the fisheries for saury, mackerel, sprat, anchovy, and 

 skipjack are discussed. The following information per- 

 taining to saury are reported; (1) saury are attracted into 

 catchable schools by overhead lights but not by underwater 

 lights, (2) saury do not make significant vertical migra- 

 tions; however, they are found In the surface waters at 

 night, (3) the amount of vertical migration tends to in- 

 crease during the autumn, and (4) the reaction of saury to 

 light may vary depending upon sexual development and 

 feeding periods.

 This is the second and concluding part of the paper by 

 Nikonorov (1965a). The following pertinent conclusions on 

 light fishing for saury are presented: (1) use many low- 

 power lights rather than a fewhigh-power lights, (2) do not 

 use blue lights, (3) dim briefly or sweep slowly back and 

 forth the lights to attract saury closer to the light source, 

 and (4) use red lights during the final fishing stage.
