 Callgus macarovi attacks both the epidermis and the 

 mucosa but never becomes imbeded In the muscular 

 tissue. Saury with scars have a lower condition factor 

 than saury without scars. The percentage of Infected saury 

 increased during the late summer and fall as the popula- 

 tions moved from the northern feeding grounds to the 

 southern spawning grounds.

 mary.) 

 North and south migration patterns of saury are dis- 

 cussed as they relate to the oceanographic conditions in 

 the sea off the Tohoku region of Japan. The so-called 

 spring-spawning saury generally occupy coastal waters 

 during the early fall, and the so-called fall-spawning saury 

 occupy offshore waters during the fall. Saury generally 

 inhabit waters of 10° to 20° C.

(IV). Bull. Tohoku Reg. Fish. Res. Lab. 



24: 48-64. (In Japanese with English 



summary.) 



It has been previously confirmed that two populations of 



saury exist in commercially fished areas during the fall. 



Possible correlations between a regular saury population 



cycle and the fluctuation of fishing conditions between 



1929 and 1963 are discussed. The author concluded that 



a stable cyclic population pattern results in good fishing; 



however, the migratory pattern may be altered from year 



to year by oceanographic variations.

 65-72. (In Japanese with English sum- 

 mary.) 

 The relation between the population density and the 

 growth of large and medium-sized saury is discussed and 

 correlated mathematically. The author suggested that the 

 population of medium-sized fish is decreasing while the 

 population of large-sized fish is increasing. The total 

 standing stock of saury is composed of two separate 

 breeding populations, which, in this article, are referred 

 to as medium and large fish.

(In Japanese with English summary.) 



Japanese saury landings for each 10-day period in 



September to December were compared during 1953-66. 



Landings increased rapidly during mid-September, reached 



one or more peaks between the last week of September 



and late October, decreased slowly until early December, 



and then dropped rapidly. The fishing peak during each 



10-day period occurred during the new moon.

 The spawning grounds of saury and the affect of tem- 

 perature on developing embryos are discussed. The authors 

 believe that saury spawn offshore in the fall, whereas 

 middle-sized fish spawn among coastal seaweed in the 

 spring. The time of hatching was 8 days at 25° C. to 

 33 days at 10° C. The biological zero temperature for 

 hatching was calculated to be 5,5° C, Temperatures of 14° 

 to 20° C. were considered optimal for the development of 

 saury eggs.

saury, Cololabis saira . Bull. Tohoku 



Reg. Fish. Res. Lab. 7: 60-69, (In 



Japanese with English summary.) 



Food and feeding habits were investigated throughout 



1951-55, The contents of about 1,500 digestive tracts 



indicated that crustaceans were the primary food source 



and Sagittoidea the secondary source. After the fish 



reaches a length of 60 mm., the type of food eaten does not 



change. The feeding rate {food weight/body weight x 100) 



of small saury is usually higher than that of adults. Saury 



feed heaviest during May to July and October to November, 



The authors also believe that saury feed heavily during the 



morning and very little at night.

California. Calif. Fish. Game 39: 127- 



131. 



The stomach contents of 32 marlin caught near San Diego 



in late August and throughout October were analyzed. 



Pacific saury constituted about 75 percent of the diet, 



both in numbers and volume. The next most abundant food 



was anchovy, which constituted about 20 percent of the 



diet by number and 12 percent by volume.

 net (Bouke- Ami) fishery. Bull. Jap. Soc. 

 Sci. Fish. 23: 745-748. (Translation by 

 Bureau of Commercial Fisheries Bio- 

 logical Laboratory, Honolulu, Hawaii, 

 U.S. Department of the Interior.) 

 The authors reported how the fishing power of the saury 

 blanket net (stick-held dip net) varies with different-sized 

 vessels, the size of the net and auxiliary equipment (num- 

 bers of alluring lights, light color and intensity). They 

 concluded that net size and the number of attraction lamps 

 have no relation with the fishing power of the Bouke-Ami* 

 and that the average catch of a iO- to 29-ton vessel is 

 about 60 percent of a vessel 30 tons or larger. Consider- 

 able information on Japanese saury vessels, crew size, 

 and fishing equipment is presented. 



♦Reviewer's note: This conclusion contradicts several 

 other studies.
