Tuna prices down

PORT Lincoln's southern bluefin tuna harvest has finished with the industry seeing close to the worst prices for fish in 20 years.

Although the quality of fish from the harvest was very high, Australian Southern Bluefin Tuna Industry Association chief executive officer Brian Jeffriess said prices were the second lowest he had seen since farming started in 1993.

He said the industry's harvest finished last week.

"It was (an) earlier finish than normal because the frozen harvest started in June, about two weeks ahead of 2012," he said.

"The final data on the harvest is not yet available but we know it is between 7000 and 7700 tonnes, including some fish put in the farms in late 2011 for longer term growout."

Mr Jeffriess said the low price for fish this season was a result of a very weak Japanese Yen.

He said an uncertain Japanese economy and heavy competition from other tuna catch from Mexico and Japan also affected the price of the fish.

"However, for 2014 and 2015, there are a lot of positive developments for Australian southern bluefin tuna including an increased quota and less competition," he said.
