COMMERCIAL FISHERIES REVIEW 



Vol. 28, No. 9 



Japan (Contd.): 



pinks, and 4. 6 percent kings and silvers, while 

 another claimed it to be 45 percent reds, 47 

 percent chums, and 8 percent pinks, silvers, 

 and kings. 



5. The reds and chums were larger in 

 size than usual. Towards. the middle of the 

 season, the reds averaged 2.3 kilograms (5 

 lbs.) per fish, with the larger fish running to 

 3 kilograms (6.6 lbs.). Chums ranged 2.3- 

 2.6 kilograms (5.1-5.7 lbs.) per fish. 



6. The newly established closed area 

 (bounded by north latitudes 48°-52° and east 

 longitudes 160°- 165°, which was closed to 

 fishing July 1-14) hardly had any effect on 

 fleet operations since fishing was good else- 

 where and the catch target was met early. 

 (The fishery ended on July 12, the earliest in 

 many years.) 



7. The weather was good and the 11 fleets 

 were able to fish almost continuously. Only 

 one catcher vessel was lost without loss in 

 lives, but there were five fatal accidents in 

 the entire fleet. ( Suisan Keizai Shimbun and 

 Hokkai Suisan, July 25; Suisan Tsushin , July 

 23, 19667)

SALMON CATCHER VESSELS LAID -UP: 



As a result of the early closure (July 12) 

 of the high-seas salmon fishery, the catcher 

 vessel owners were at a loss to know how to 

 use their vessels. Usually the salmon fish- 

 ery lasts into mid-August and the vessels 

 then fish for saury, bottom fish (trawl), or 

 cod (long line). This year the owners had an 

 extra month's time for which work for their ■ 

 vessels needed to be found. (Fisheries At- 

 tache, United States Embassy, July 28, 1966, 

 from Suisan Keizai , July 19, 1966.)

DEVELOPMENTS IN SALMON 



AND TROUT CULTURE: 



The Miyagi Prefectural Experimental Sta- 

 tion has been conducting experiments on the 

 culture of salmon and rainbow trout at sea. 

 The fish were held in cages of seven cubic 

 meters' in size and suspended at a depth of 

 lOmeters. They were introduced in the cages 

 (number not given) and fed an artificial diet. 

 In 20 months, the 200 rainbow trout remain- 

 ing in the experiment had grown to a size 5 



times that of wild fish kept in fresh water. 

 The meat was red and of excellent flavor. 

 Salmon (species not given) were also reared 

 in the same way. The 400 remaining after 18 

 months had reached an average size of 500 

 grams or about 50 percent greater than wild 

 fish in the ocean. The flavor was not as good, 

 however, as that of wild fish. 



The Japan Salmon Resources Conserva- 

 tion Association has asked the Fisheries 

 Agency to take whatever steps are necessary 

 to increase salmon hatchery production to 1 

 billion eggs a year. (Fisheries Attache, 

 United States Embassy, Tokyo, July 13, 1966.)

EXPORTS OF FROZEN RAINBOW 



TROUT, APRIL 1966: 



In April 1966, Japan exported a total of 

 246.1 short tons of frozen rainbow trout val- 

 ued at US$168,937. This amount is almost 

 identical with the 246.1 tons exported in the 

 previous month but the export value is con- 

 siderably less, being about $10,843 below the 

 value reported for March. (Fisheries Atta- 

 che, United States Embassy, Tokyo, June 24, 

 1966.)

JAN. -MAR 1966: 



In March 1966 Japan exported a total of 

 1,211 metric tons of canned salmon valued'at 

 US$2,224,636. There was a continuing in- 

 crease in exports of canned salmon in the 

 first three months of 1966: January 841 tons; 

 February 1,102 tons; March 1,211 tons. 



The United Kingdom received 88 percent 

 of the March exports from Japan; Australia 

 received about 8 percent; and Belgium about 

 3 percent. Exports to all other countries
