Fingerling Production in Japan Interim Report Sep. 2002 - Aug. 2003
Reported by Aqua Culture Network

1.Red Sea Bream
SALES:Approx 50 million fingerlings (To fish farmers)
-produced by 32 private hatcheries. 15 million fewer than last year.-
It seems that many hatcheries still have a lot of fingerlings in stock, and this slump in the aquaculture industry lasts until the stocked larval fishes are cleared off. The price is expected to be recovered in the end of this year since there are so many extremely cheap fishes in the market sold for the purpose of converting into money, and the production of last year is fewer by 15 million fishes than the year before last. But so many hatcheries are in financial difficulties.
PRICE:Expected to be JPY70-80/fish(7cm up size, EX-firm) although it is very difficult to figure out the prices exactly. When Tatego fishes were sold at a loss last autumn some fingerlings were sold at lower than JPY50/fish.
*Tatego:The fingerings hatched before Bon Festival (Aug. 15) and sold within the year.

SALES:Approx 13.5 million fingerlings (To fish farmers)
-produced by 31 private hatcheries. 1.5 million lower than last year-
PRICE:JPY115/fish(5cm up size, Sold this January)
The price of adult fishes declined sharply in the autumn of 2000, but thanks to the improved quality and decreased imports of China origin puffers, the price had been recovered to be JPY2,500-4,000/kg (kg size). It was expected that the demand for fingerlings increase since it was reported that Nagasaki prefecture had decided to cope with the formalin disinfection problem occurred in Takashima city, Nagasaki at their public expense. But in fact they denied it , so the surplus larval fishes has started to be sold at a loss since the middle of this June, and some fingerlings were sold at JPY30/fish at the of this June
It is expected that the home-produced puffers will decrease, but China origin puffers(200g size-adult) will be imported more.

SALES:Approx 9.5 million fingerlings (To fish farmers)
-produced by 26 private hatcheries.-
4.5 million lower than last year, and the worst sale in the past. -.
The reasons for this small production are supposed as follow
The farmers had no empty tank since Korean origin flatfishes were imported all year round and the demand for high-price fishes was low.
  The start of culturing season was delayed due to the low price of adult fish(JPY1,100-1,500 EX-farm)
  The damages of virus diseases such as VNN and VHS, bacteria disease, and deformity have been more serious year by year. So it was expected that the fingerlings would be in short supply in this July, but in fact the stocked fishes hadn’t been sold well as expected. So 250 thousand fingerlings (10cm up size) still have been stocked by the hatcheries.
PRICE:JPY85-100/fish (6cm up size, Sold last Oct.)
JPY70-90/fish (7cm up size, Sold from last Nov.-)
JPY60-70/fish (Sold from the beginning of this year-)
The price of Korean origin (in Korea) is 10,000-12,000.-/fish (JPY1,000-1,200.-), and the Korean farmers are in financial difficulties, so some farmers in Yeosu and Chung Mu have give up their business. Now the main producing district in Korea is Jeju Island.

4.Striped Jack
SALES:Approx 3.1 million fingerlings (To fish farmers)
-produced by 6 private and 2 public hatcheries. 50 thousand lower than last year-.
There still have many problems to be solved, such as the way to secure and select the breeding stocks, measurement for Virus, selection for living feeds although the hatcheries are trying to solve the problems by using PCR and so on.
PRICE:JPY1,600/kg (EX-farm)
The prices are staying high for these years since the fingerling are in short supply.

5.Ocean perch
SALES:Approx 1.2 million fingerlings (To fish farmers)
-produced by 3 private hatcheries. 50 thousand lower than last year-.
An Ocean perch grows up slowly, and it takes more than 150days to bring up the larval fish to be 6cm size, but the larval fish can be sold at a good price in brocks of 100 thousand fishes. Furthermore 100 thousands fishes can be cultured in a 10M square tank and the fish can grow up even at a low temperature.
PRICE:JPY60/fish (6cm size)
The Korean origin fishes, which are said to grow up better, are used as breeding stocks. If the well-selected fishes can be brought up to breed stocks successfully, it is expected that the fishes which grow up much better is available

6.Sweet fish
Production:Total approx 200 million thousand
For release:100 million (1,164ton)
For farming:90 million (8,000ton, as an average 90g/fish)
70-80% of the produced fishes were Biwa Lake origin 7years ago, but now about 60% are artificially hatched fishes. It is expected that the reasons for this change are the disease such as Cold Water Disease which are often seen in Lake origin fishes and the improvement in producing fingerlings artificially. The sum of fingerling production was 60-70 million( produced by both private and public companies), but this year it has increased to be about 140million since the number of companies specialized in selling fingerlings and the hatcheries which also have fish farms has increased.
The number of hatcheries has also increased and there seem to be 40 public hatcheries and 30 private hatcheries now.
But even now many problems still remain to be solved in artificial larval fishes, The instability in sizes of scales, forms of fishes, and producing larval fishes whose hatching time is staggered to be shipped frozen or with spawn.

Stingfish, Rockfish, Mackere, Moara grouper, Grouper, Amberjack, Yellowtail, Sole, Leatherfish, Japanese perch, and milkfish are cultured.
